Overview Of Cooling System Engineering Essay

In order to cut downing fuel ingestion and run into the emanation criterions, many betterments has been made. The illustrations of the betterments are combustion schemes, fuel injection system, exhaust emanation and fuel quality [ 1 ] . There are four possible beginnings of atmospheric pollution from the car. Without emanation controls, a carburettor and fuel armored combat vehicle emits bluess, the crankcase emits blowby gases and the tailpipe emits exhaust gases that contain pollutants. The chief regulated pollutant in engine fumes are nitrogen oxides ( NOx ) , C monoxide ( CO ) , unburned hydrocarbon ( HC ) and smoke [ 2 ] . These air pollutants are harmful to human existences every bit good as workss and animate beings. The jurisprudence now requires automotive makers to put in emanation controls. Car that gives away inordinate sum of air pollutants may non be allowed on the streets someday. Stronger Torahs restricting automotive air pollution and compulsory review and care has been proposed. These Torahs are portion of the authorities policy that autos must lend every bit small as possible to the job of air pollution. Each auto already have three major systems for commanding pollutants from these beginnings that is positive crankcase airing ( PVC ) , evaporative emanation control and exhaust emanation control. But in this survey we want to concentrate more on engine chilling system and its effects to the emanation decrease, fuel ingestion and engine public presentation. Now, we will through about the constituents of engine chilling system and its maps. Engine chilling system is a system that responsible for chilling the engine by let go ofing heat through the chilling fives so that the auto & A ; acirc ; ˆâ„ ¢s engine is non excessively hot or non excessively cold. This system helps to convey the engine up at to normal runing temperatures every bit rapidly as possible and maintain the operating temperature for efficient map of the auto engine. It is really of import to maintain the engine at its most operating temperature at all velocities and runing conditions. Burning fuel in the engine produces heat. Some of the heat must be taken away before it amendss the engine parts. This is one of the occupations that performed by the chilling system. If the engine temperature is excessively low, fuel ingestion will lift and if the temperature is excessively hot for excessively long, the engine will overheat.1.2 TYPES OF COOLING SYSTEMThere are two types of auto chilling system which is the air chilling system and liquid chilling sys tem. Air chilling system is a system that uses air as a chilling agent. It is normally used in individual cylinder engines such as bikes while liquid chilling system is known as the radiator system. It a system that uses liquid as a chilling agent and is used in a multi-cylinder engine such as autos and trucks. Radiator is the important constituents in the auto chilling system. It ensures the engine is non overheating. Figure 1.1: Cooling System Components [ 12 ]1.3 COMPONENTS OF COOLING SYSTEM1.3.1 WATER JACKETFor operation of the chilling systems, it uses five basic parts or constituents to make the occupation in commanding the engine temperature that is H2O jackets, H2O pump, thermoregulator, radiator and fan. Water jackets are unfastened infinites between the cylinder walls and the outside shell of the block and caput. Coolant from the H2O pump flows foremost through the block H2O jackets. Then, the coolant flows up through the cylinder caput H2O jackets and back to the radiator.1.3.2 WATER PUMPWater pump normally known as impeller pumps. It is attached to the forepart of the engine and are driven by a belt from crankshaft block. The pump circulates every bit much as 28 390 L of coolant an hr. As the impeller rotates, the curving blades draw coolant from the underside of the radiator. It forces the coolant from the pump mercantile establishment to the H2O jackets. The impeller shaft is supporte d on certain bearings which ne'er need lubrication. The seals prevent the coolant from leaking past the bearings.1.3.3 RadiatorRadiator is a heat money changer that removes heat from engine coolant that go throughing through it. The heat transportation from the hot coolant to the ice chest outside air. It has three chief parts that is radiator nucleus, recess and mercantile establishment armored combat vehicles. The nucleus consists of set of tubings and set of fives that attached to the tubings. Figure 1.2: Coolant Flow Inside Engine Cooling System [ 12 ] C: UsersFaisal Mamat.FaisalMamat-PCDesktopCapture.PNG1.3.4 ThermostatFor thermoregulator, it is a heat operated valve that regulates the coolant temperatures. It does this by commanding the coolant flow from the engine to the radiator. The thermoregulator is in the coolant transition between the cylinder caput and the radiator. The valve in thermostat stay unfastened and close as coolant temperature alterations. Equally long as the coolant temperature is below the thermoregulator set point, the thermoregulator remains closed. Once the temperature arrives at the set point, the thermoregulator starts to open, directing heated coolant through the radiator. The radiator so cools the het engine coolant and the H2O pump forces the coolant back through the engine. The transition to the radiator is closed when the engine is cold so the engine can warms up more rapidly. Engine heat corsets in the engine alternatively of being carrie d to the radiator. Figure 1.3: Closed Position of Thermostat [ 12 ] Figure 1.4: Open Position of Thermostat [ 12 ]1.3.5 ELECTRIC FANAn electric fan is turned on by thermostatic switch merely when needed. For illustration, it turns on when the coolant temperature reach 93 & A ; Acirc ; & A ; deg ; C and turn off back the fan if the coolant drops below this temperature. But on vehicles with air conditioning, turning on the air conditioner bypass the thermostatic switch. The fans run all the clip when air conditioner is on. The fan is controlled by electronic control faculty ( ECM ) in many vehicles with an electronic engine control system.1.4 PROPERTIES OF COOLANT1.4.1 TAP WATERTap H2O is drinkable H2O supplied to a pat inside the family or workplace. The application of engineerings involved in supplying clean H2O to places, concerns and public edifices is a major subfield of healthful technology. Specific chemical compounds are frequently added to tap H2O during the intervention procedure to set the pH or take contaminations, every bit good as Cl to kill biological toxins. The usage of tap H2O adversely affect the auto chilling system. Tap H2O contains Mg and Ca ions that will organize the xanthous precipitate ( rust ) when the H2O becomes hot. The xanthous precipitate will be attached to the auto engine after long clip period and this will cut down the soaking up of heat from the engine. If this rust become denser, it can interfere the transition of chilling liquid in the auto chilling system.1.4.2 ETHYLENE GLYCOL ( EG )Ethylene ethanediol is an organic compound widely used as an automotive antifreeze and a precursor to polymers. In its pure signifier, it is an odorless, colorless, syrupy, sweet-tasting liquid. Ethylene ethanediol is toxic, and consumption can ensue in decease. Ethylene ethanediol is produced from ethene via the intermediate ethene oxide. The major usage of ethene ethanediol is as a medium for convective heat transportation. For illustration, cars and liquid cool ed computing machines. Pure ethene ethanediol has a specific heat capacity about one half that of H2O. So, while supplying freezing protection and an increased boiling point, ethylene ethanediol lowers the specific heat capacity of H2O mixtures relative to pure H2O. A 50/50 mix by mass has a specific heat capacity of about 0.75 BTU/lb F, therefore necessitating increased flow rates in same system comparings with H2O.1.5 FuelGasoline is a transparent, crude oil derived liquid that is used chiefly as a fuel in internal burning engines. It consists largely of organic compounds obtained by the fractional distillment of crude oil, enhanced with a assortment of additives. Some gasolene besides contain ethanol as an alternate fuel. A good gasolene quality should hold: Proper volatility, which determines how easy the gasolene vaporizes. Resistance to trip knock or explosion. Oxidation inhibitors, which prevent formation of gum in the fuel system. Antirust agents, which prevent rusting of metal parts in the fuel system. Detergents, which maintain aid maintain the carburettor or fuel injectors clean. Dye for designation, such as ruddy oculus which gives leaded gasolene a rust or orange coloring material.1.5.1 VOLATILITYVolatility is the easiness with which a gasolene vaporizes. Gasoline must zap rapidly after it is assorted with air in the throttle organic structure or intake manifold. Otherwise, beads of liquid gasolene enter the cylinder walls. This increases wear of the cylinder walls, Pistons and rings. Gasoline that does non zap will non fire. It leaves the cylinder in the fumes gas and pollutes the air. This wastes gasolene and reduces fuel economic system. Volatility determines how rapidly a gasolene can zap. A high volatility gasolene can zap rapidly while a low volatility gasolene vaporizes easy. Gasoline must hold the right volatility for the clime in which it is used.1.5.2 ANTIKNOCK QUALITYAntiknock is known as octane evaluation. It measure the gasolene ability to defy knock during burning. The higher the octane evaluation, the greater the engine ‘s opposition to strike hard. The knocking in your engine occurs when the air fuel mixture detonates prematurely. Since it is the gasolene vapour that ignites, the air fuel mixture must be right to fire swimmingly. Some of the jobs associated with knock are overheating of engine parts such as valves, Pistons and flicker stoppers.1.6 EmissionThen we will travel for the account about the burning in the engine and how it ensuing emanation. Automotive fuels such as gasolene are made largely of two elements that H and C. They have chemical symbols H and C. This type of fuel is hydrocarbon ( HC ) . During complete burning in the engine, these two elements unite with other component, the gas O. Oxygen, normally in the signifier of free O ( O2 ) , makes up approximately 20 per centum of the Earth atmosphere. This is the air that we breathe. During burning procedure, each atom of O will unify with two H atoms. Each C atom unites with two O atoms. Oxygen unifying with H green goodss H2O ( H2O ) . Carbon unifying with O green goodss gas C dioxide ( CO2 ) . During burning, the combustion of air fuel mixture in the engine cylinder may make 2200oC or higher. This high temperature produces force per unit area in the engine that makes it run and produces power. With perfect burning, all the H and C in gasolene would unify with the O. The fumes would incorporate merely harmless H2O and CO2. But burning is non perfect in the engine. Some of the gasolene ( HC ) does non fire. Besides, some of it merely partially burns. This produces C monoxide ( CO ) . This deficiency of O prevents the formation of C dioxide. The unburned gasolene and partially burned gasolene ( CO ) issue from the engine through the tailpipe. Once in the air, it will do atmospheric pollution. Another group of atmospheric pollutants the engine is nitrogen oxide ( NOx ) . About 80 per centum of the ambiance is gas N ( N ) . High temperatures in the burning chamber do some of the N and O to unify and organize N oxide ( NOx ) .1.7 PROBLEM STATEMENTNowadays the rate of fuel ingestion presently traveling on throughout the universe is rather dismaying. Fuel ingestion and emanation rates are off the chart. This will give negative impact to the environment and increase the pollution rate. Basically the power to travel a motor vehicle comes from the combustion of air fuel mixture in an engine. Air pollutants from vehicles comes from the merchandises of this burning procedure. With perfect burning procedure, the emanation would be H2O ( H2O ) and C dioxide ( CO2 ) . Both of these are harmless gases. But burning is non perfect in an engine. Some of the gasolene ( HC ) does non fire and some of it merely partially burns. This produces C monoxide ( CO ) and nitrogen oxide ( NOx ) . Both of these gases are air pollutants and take a breathing contaminated air is really bad for human and animate beings. Then the demand for low cost auto from client that has good public presentation with low fuel ingestion and emanation besides addition. Normally auto that has good public presentation will hold high fuel ingestion and emanation rate. In order to work out these jobs, the survey about engine chilling system and its effects towards engine public presentation, fuel ingestion and emanation decrease will be conducted. Two types of liquid chilling such as tap H2O and ethene ethanediol will be used and its temperature will be checked in order to look into the influenced to these 3 end products.1.8 OBJECTIVES OF THE RESEARCHTo analyze the consequence of engine chilling system and its constituents to the engine public presentation, fuel ingestion and emanation. To look into the influence of per centum of ethene ethanediol in the coolant and coolant temperature set point to the engine public presentation, fuel use and emanation rate.1.9 SCOPE OF THE RESEARCHThe range of this researched is chiefly about the fluctuations per centum of coolant ( ethylene ethanediol ) mixed with H2O and its temperature effects towards engine public presentation, fuel ingestion and emanation. The per centum that will be used for ethylene ethanediols are 30 % , 50 % and 70 % . For every per centum, the coolant temperature set point will be controlled utilizing two sort of thermoregulator with temperature set point 80oC and 100oC. The increasing temperature in cylinder block by increasing the coolant temperature consequences in fuel nest eggs and emanation decrease.

Then for the fuel, gasoline RON 95 will be used. Three trial will be conducted in investigate the engine public presentation, fuel ingestion and emanation rate. The trial for engine public presentation is dynamometer trial. A ergometer is a device that is used for mensurating force, minute of force ( torsion ) , and power. For illustration, the power produced by an engine, motor or other revolving premier mover can be calculated by at the same time mensurating torsion and rotational velocity ( RPM ) . For the fuel ingestion, we will carry on a fuel trial by utilizing a new armored combat vehicle provided by automotive lab. Unit of measurement to mensurate the fuel trial is in liter/km. To mensurating the emanation rate, gas analyser is used and the measuring unit is in concentration of gas which is parts per million ( ppm ) .1.10 SIGNIFICANT OF THE RESEARCHThis survey will give better apprehension and exposure about the operation in the engine chilling system and how it will effects the engine public presentation, fuel ingestion and emanation. Reducing the fuel disbursals by auto users as the rate of fuel ingestion reduced. The expected end product to cut downing the emanation will ensue in increased the air quality that is harmful to worlds. It besides will take in cut downing the air pollution rate and supply more safer environment for people. The low cost auto with good public presentation and low on fuel and emanation rate besides will be develop.2.0 LITERATURE REVIEW2.1 Cooling SYSTEM OPERATIONA immense sum of heat is generated in the internal burning engines. It is created when the air fuel mixture is ignited inside the burning chamber. The detonation that occur will do the Piston to be forced down indoors the cylinder, prying the connecting rods and turning the crankshaft. The temperatures of the metal parts around the cylinder can transcend 2500oC. To forestall the constituents such as engine oil, cylinder walls, Pistons, and valves from overheating, it is necessary to efficaciously dispose the heat. Approximately 30 % of heat in the burning procedure is lost into the ambiance through the fumes system, 35 % is converted into power to drive the vehicle and the staying 35 % lost as heat through the cylinder walls [ 9 ] . Water pump is attached at the forepart of the engine and driven by a belt from crankshaft block. The impeller rotates and the curving blades draw liquid chilling from the underside of the radiator and force it to flux through pump mercantile establishments and H2O jackets. The liquid chilling will flux through passageways in the engine block and cylinder caput. Temperature in the burning chamber can around 2500oC, so chilling around this country is critical to forestall overheat. The countries around exhaust valve are particularly important and about all infinite inside the cylinder caput around the valve that is non needed for construction filled with coolant. But when the engine is still cold, thermostat still near and the liquid chilling is circulated back to the engine. By shuting the transition through radiator when engine is cold, the engine warms up more rapidly. Engine heat corsets in the engine alternatively of being carried to the radiator. This shortens warms up clip, wastes less fuel and reduces exhaust emanations [ 3 ] . After engine already heat up, the thermoregulator keeps the engine running at a higher temperature than it would without a thermoregulator. The higher operating temperature improves engines efficiency and reduces exhaust emanations [ 3 ] .2.1.1 EFFECT OF RADIATORA radiator normally known as heat money changer. The hot coolant that flows through it will reassign the heat by the air blown through the aluminum fives by fan. Nowadays modern autos use aluminium radiators. It normally made by brazing thin aluminum fives to flattened aluminum tubings. Flow of the coolant is from recess to the mercantile establishment through many tubings that mounted in parallel agreement. These fives will carry on the heat from the coolant inside the tubings and reassign it through the air that fluxing through the radiator. [ 1 ] A type of five is inserted into the tubing called turbulator. Its map is to increases the turbulency of the fluid fluxing through the tubings. If the flowing of the fluid through the tubing is smooth, merely the fluid that touching the tubings would be cool straight. The sum of heat transferred from the fluid to the tubes depends on the difference in the temperature between the tubing and the fluid touching it. Therefore, less heat will be transferred if the fluid that is in contact with the tubing cools down rapidly. To forestall that, turbulency is created inside the tubing and all of fluid mixes together. Keeping the temperature of the fluid touching the tubing up so that more heat can be extracted and all of the fluid inside the tubing is used efficaciously.2.1.2 EFFECT OF RADIATOR FANThe map of radiator fan is to pull the air towards the radiator and helps to chill the hot coolant that fluxing through the tubings. It normally has four or more blades that spin quickly to supply s ufficient air to that would chill the engine. The fan will be mounted between the radiator and the engine so that the air can easy fluxing through the radiator. There are besides extra fan in forepart of the radiator in some autos in order to pull more cool air to the engine particularly when vehicle is non traveling fast plenty, really small cool air reaches the radiator and the engine is non cooled decently.2.1.3 EFFECT OF PRESSURE CAPThe radiator cap or besides known as force per unit area cap really increases the boiling point of your coolant by about 25oC. The cap is a force per unit area release valve and normally is set to 15 pounds per square inchs. When the coolant is placed under force per unit area, its boiling point will increase. As the engine running, the chilling system will be heated up and increase the force per unit area. The lone topographic point where the force per unit area can get away is at the force per unit area cap. Therefore, the scene of the spring on th e cap determines the maximal force per unit area in the chilling system. If the force per unit area reaches 15 pounds per square inch, it will force the valve unfastened and leting the coolant to get away from the chilling system. The flowing of the coolant is from overflow tubing to into the underside of the overflow armored combat vehicle. This sort of agreement will maintain air out of the system. After the radiator is already cools back down, a vacuity is created in the chilling system that pulls unfastened another spring loaded valve while sucking the H2O back in from the underside of the overflow armored combat vehicle to replace the H2O that was expelled.2.1.4 EFFECT OF WATER PUMPWater pumps are impeller pumps. They attached to the forepart of the engine and driven by a belt from the crankshaft block. As the impeller rotates, the curving blades draw coolant from the underside of the radiator [ 3 ] . The H2O pump merely thrust to drive the round flow of the coolant within the engine chilling system, so the recess is the point of lowest force per uni t area in the system and the issue point is the highest force per unit area. The force per unit area drops aggressively at the inlet/outlet of the H2O pump during the operational of the H2O engines and this force per unit area bead will change in proportion to the rotational velocity. Water pumps in engines are prone to cavitation and air bubbles are likely to pervade in to antifreeze and will badly cut downing the public presentation, dependability and service life of the engines [ 6 ] . Cavitation means the pits or bubbles are organizing in the liquid that have been are pumping. These pits form at the low force per unit area or suction side of the pump. For the well design engine chilling system, cavitation is less likely to take occur as the temperature of the coolant diminutions. But when the cavitation temperature is reached, the force per unit area of the H2O pumps drops suddenly and all the chilling system loses its functionality.2.1.5 EFFECT OF THERMOSTATThe chief map of the thermoregulator is to let the engine to heat up rapidly and maintain it at its efficient temperature. It control this by modulating the sum of H2O that goes through the radiator. The coolant in the chilling system starts to originate by picking up heat at the H2O jackets. In the coolant circuit, the force per unit area gradient exist and doing the hot coolant flows out from the engine to the radiator or to coolant beltway transition [ 2 ] . Once the temperatures of the coolant rises to 80oC, the thermoregulator starts to open. Different thermostat unfastened at different temperatures and leting fluid to flux through the radiator. The secret of the thermoregulator lies in the little cylinder located on the engine side of the device. Actually this cylinder is filled with wax that starts to run at temperatures 80oC ( depends on the thermoregulator ) . Then, a rod that is connected to the valve imperativeness into this wax. As the wax thaws. It will spread out and forcing the rod out o f the cylinder and opening the valve.2.2 EFFECT OF COOLANTCoolant is the mixture of antifreeze and H2O in the chilling system. The normally used antifreeze is Ethylene Glycol. This coolant will go around through the chilling system. It will take the waste heat from the engine and delivers the heat through the radiator hosiery to the radiator. It is non recommended to utilize merely H2O as a liquid chilling because it would stop dead if the temperature bead below 0oC. This would halt the circulation and the engine would overheat. As the H2O would spread out 9 % as it freezes, it would check the cylinder block and caput, split the radiator [ 3 ] . By commanding the engine chilling system in a flexible manner as comparison to the conventional chilling system, it will better the fuel ingestion rate of flicker ignition ( SI ) engines [ 11 ] . It is known from the cold start research that the coolant and inlet charge temperature are cardinal parametric quantities to cut down pollutant emanations and warrant smooth engine operation. Cold start experiment were performed with coolant temperatures of 15oC and 80oC. In the steady province operation reached after the start, the Piston surface temperature was severally 110oC and 150oC. The HC emanations were 25 % lower and the NOx emanations 7 % higher with the higher coolant temperature. It seems to bespeak that there is an influence of the coolant temperature on the emanations through the cylinder wall temperatures [ 5 ] . In the hunt for greater fuel economic system and decreased emanation end product, the engine chilling system is being targeted for farther betterments to engine public presentation through its effects on engine frictional losingss. Fuel economic system betterments from the alterations to the engine chilling system are derived chiefly from reduced engine frictional losingss with increased oil temperature by raising the engine operating temperature indirectly through the measure addition in the coolant temperature. Hydrocarbon ( HC ) and C monoxide ( CO ) end product are besides shown to diminish with the addition in operating temperature [ 7 ] . There are besides suggestion that higher cylinder block temperatures will cut down the frictional losingss with the Piston and pealing battalion and will take to cut downing fuel ingestion [ 10 ] . But the increasing of operating temperature has a negative consequence on N oxide ( NOx ) end product as the formation of NOx in the burning chamber can be extremely sensitive to temperature alterations [ 7 ] . There are some old plants in the engine chilling country focal points on to the fuel economic system benefit to IC engines through the decrease engine frictional losingss by raising the coolant temperature. As the coolant temperature additions, the cylinder block wall temperaturs besides increases and will ensue in cut downing the HC emanations [ 11 ] . It concentrates chiefly on gasolene engines where oil temperature is comparatively lower and the tailpipe emanations are HC and CO. Fuel efficiency betterments about 10 % are achieved in portion burden conditions by raising coolant temperature [ 7 ] .Methodology3.1 IntroductionIn this chapter, we will discourse about the processs and full activities to transport out in this whole undertaking. The flow chart below will depict the stairss that should be followed during this undertaking. Basically there are 3 trial that will be conducted that is dynamometer trial, fuel trial and emanation trial.3.2 FLOW CHARTPart Choice Choose the type of liquid chilling and thermoregulator that will be used. Preparation and Setup Choose the type of liquid chilling and thermoregulator that will be used. Run the experiment The experiment will be conducted to the conventional and modified chilling system. Emission Trial Fuel Trial Dynamometer Test Datas AnalysisTYPES OF METHODS3.3.1 DYNAMOMETER TrialDynamometer is really a device usage to mensurating force, minute of force ( torsion ) and power produced by an engine or motor. We can see the illustration from the power produced by an engine, motor or other revolving premier mover can be calculated by at the same time mensurating torsion and rotational velocity ( RPM ) . Nowadays dyno trial become more easy to run with the progress of the modern computing machine and bring forth more accurate consequences. A dyno that paired with the computing machine will expose the power evaluation of a given machine as a figure below. Degree centigrades: UsersFaisal Mamat.FaisalMamat-PCDesktopdynamometer-test-2.1-800Ãâ€"800.jpg Figure 3.1: Example Graph of Dynamometer Test Actually dyno trial is used for assorted applications but the most common one is automobile proving. Automobile makers will mensurate the public presentation of a auto or truck in order to market its power. Sports auto will modified their vehicles with aftermarket parts in order to accomplish higher power end product and so run the dyno trial to measure their alterations. Dyno trials can be run in a twosome of different ways which is human body and engine dyno. When running a human body dyno trial, the vehicle to be tested is driven onto the dyno platform that simulates opposition through the usage of machine-controlled wheels. For an engine dyno trial, the engine to be tested is mounted to the dyno device. These different methods produce different measurings such as brake Equus caballus power and torsion from a human body dyno and flywheel Equus caballus power and torsion from an engine dyno. Power is frequently lost through the thrust train of a vehicle so the brake measuring will typically less than the flywheel measuring. The theoretical account that will be used for ergometer testing is Dynapack 3000. The constituents of Dynapack 3000 consists of computing machine, detectors hub adapters accountant and power soaking up units. This trial is a spot from other dyno trial because of the riddance of the tyre to roller interface on a conventional roller dyno. It eliminates this variable by utilizing a hub adapter that provides a direct yoke to our power soaking up units. There will be no tyre faux pas, no turn overing opposition and no opportunity of the vehicle coming off from the dyno at high velocities. For the theory of operation. First the hubs of the vehicle are straight attached to hydraulic pumps. A variable burden can be applied with all of the possible keeping power that hydraulic possess. Figure below show that the wheels are removed from the vehicle and the variable fit hub adapters are bolted to the vehicle axle. The hub adapter is so straight attached to a hydraulic soaking up unit.

CompanyCompany may be defined as a voluntary association of individuals. It is an association of persons formed for some common intent but chiefly it is a voluntary association of individual. It has capital divisible into parts, known as portions. At the same clip it is an unreal individual created by a procedure of jurisprudence. It has a ageless sequence and a common seal. It exists merely in contemplation of jurisprudence ; i.e.it is regarded by the jurisprudence as a individual, merely as a homo. On incorporation of a company becomes a organic structure corporate or corporation with a ageless sequence and a common seal. It besides acquires a personality distinct from its members.Features Of A Company1. Separate legal entity 2. Limited liability 3. Ageless sequence 4. Common seal 5. Transferability of portions 6. Separate belongings 7. Capacity to actionElectronic MediaIt is media that uses electronics or electromechanical energy for the terminal user ( audience ) to entree the content. This is in contrast to inactive media ( chiefly print media ) , which are most frequently created electronically, but do n't necessitate electronics to be accessed by the terminal user in the printed signifier. Most new media are in the signifier of digital media. However, electronic media may be in either parallel or digital format. Although the term is normally associated with content recorded on a storage medium, recordings are non required for unrecorded broadcast medium and on-line networking. Any equipment used in the electronic communicating procedure ( e.g. telecasting, wireless, telephone, desktop computing machine, game console, hand-held device ) may besides be considered electronic media.Incorporation Of CompanyBefore a company is formed, certain preliminary determinations are necessary, for illustration, whether it should be a private company or a public company, what its capital should be, and whether it is worthwhile organizing a new company or pickings over the concern of an already established concern. All these determinations are taken by certain individuals known as â€Å"promoters† . They do the full necessary preliminary work minor expense to the formation of the company.Public Ltd CompanyA Public Limited Company is a Company limited by portions in which there is no limitation on the maximal figure of stockholders, transportation of portions and credence of public sedimentations. The liability of each stockholder is limited to the extent of the unpaid sum of the portions face value and the premium thereon in regard of the portions held by him. However, the liability of a Director / Manager of such a Company can at times be unlimited. The minimal figure of stockholders is 7.

EC 444 Essay Example | Topics and Well Written Essays - 500 words

EC 444 - Essay Example When income becomes scarce, the curve flattens. The third property is indifference map which reflects different levels of utility. An individual will attain maximum total utility on the highest position of the indifference curve. The fourth property is work-leisure preference of the individual. The shape of the curve is determined by individual’s preferences, occupation, and personal circumstances. A flat curve reflects a person with an occupying job. A nursing mother will have a relatively steep indifference curve because much of her time is spent on non-labor market activities. An individual’s budget is controlled by the amount of wages earned. Budget constraint is reflected by the wages earned and this has an overall effect on the shape of the indifference curve. Individual’s maximum utility is attainable at the highest position on the indifference curve. Changes in wage rates have an effect on the number of working hours. An increase in the number of working hours increases the wage rate but with time wage increase may reduce the number of working hours. Wage rate is affected by income and substitution effects.

Industrial action Essay Example | Topics and Well Written Essays - 500 words

Industrial action - Essay Example If we are to look into this problem 17 years ago, it was stated that A 1990 survey of working time found that just over one in 16 employees in Britain had their working hours calculated on an annual basis.(1) At present there are a lot of workers that are being paid in output basis rather than the time they consume to finish the work. These works includes the likes of care giving, freelance jobs, journalists and the likes. The kind of workers that are included in these fields are paid in an output basis which most of the companies does, because according to the companies, these people are not required to attend regular working hours and the hours that they consume in fulfilling their tasks are not that identical and this prompted these companies were compelled to do such acts. However, this scheme was not accepted by majority of the workers and this scenario oftentimes creates conflicts and clashes between the workers and the employers. There are accounts that workers are either offered with favorable amount in order for the companies’ make the workers feel that they are compensated. In this way, the workers would think twice in bringing work related matters to the court, particularly the rights of the workers that are deprived by some of the employers. However, workers and managers must know their duties and their limitations. Furthermore, Abramson claimed this vintage virtue stating â€Å"Wherever authoritative roles exist, they differentiate between those who command and those who obey. Moreover, in any organization we can differentiate between those who participate in the hierarchy of command, regardless of their position in this hierarchy, and those who are subordinate.† This means that whatever the circumstance, the workers must comply with the kind of leadership his manager employs. If we are to base it in a British management perspective which deals with relationship with

Cave drawings by natives are often regarded as the earliest form of graffiti irrespective of the fact that it did not have an artistic touch. However, the first form of modern graffiti is believed to have begun in ancient Greece specifically the city of Ephesus which is known as Turkey today. This graffiti is somewhat different from the graffiti practiced today in terms of content in that it was used to communicate messages. For example, in the ruins of the city of Ephesus there is a graffiti composed of a foot, a number and a heart which communicate that there was a brothel nearby. This graffiti is found on a stone and mosaic walk away in the city. There are also drawings of bald men on walls in the city which was used to refer to politicians at the time.

How does the Study of Heat Relate to the Kinetic Theory of Matter Essay

How does the Study of Heat Relate to the Kinetic Theory of Matter - Essay Example If an equal amount of heat is supplied to all of them, the gas will be the first matter to break apart because of its loosely bound particles. On the other hand, a liquid substance would break due to the stretching ability of its particles reacting against the forces of attraction. However, solids take time to break apart and hence, possess the ability to break apart slowly as compared to liquids and gases. Ans. Heat is a form of energy. It is formed in a substance due to the movement of its atoms and molecules in a random motion. When energy is induced in an object, it causes the atoms and the molecules of an object to move at a higher speed thus causing heat in the object. It has also been found out that even the cold objects possess some degree of heat in them because of the movement of their atoms and molecules. Joules is used as a standard unit to measure heat. Ans. The average heat or thermal energy of the particles in an object is known as the temperature of that substance. It is important to know that, since temperature is the average measurement of the heat or the thermal energy, therefore, it is not dependent on the quantity of the particles present in an object. It is the physical property of an object which differentiates between the degree of hotness and coldness. Temperature has three standardized temperature scales such as Kelvin (K), Celsius (C), and Fahrenheit (F). However, Celsius is widely used around the world to measure temperature. Ans. Heat and temperature are closely interrelated with each other. Their relationship is dependent on the change in the state of the matter from solid to liquid and then to gas. We know that heat is a form of energy whereas, the temperature is the effect produced by the heat.

There are still many obstacles women have to overcome before substantial progress can be made on their behalf. In this paper we are going to test a hypothesis that in order for the women of South Africa to develop and take on a more hands on approach toward their future and their country's future they must demand and be given the right and opportunities afforded their male counterparts.This essay discusses that since the dawn of 20th century women of South Africa have been really active in the political and economic life of the country. They were active participants in different kinds of organizations including liberation movements which highlighted their importance in South Africa development. Trade union movements and their stri kes were the road to politicize women.  From 1920s women started to organize, by 1930s women trade unionists led the opposition. With the development of economy in the 1930s and 1940s women became urbanized which gave them power to organize other women and black industrial workers. Though their efforts were crippled by the legislation, they still led illegal strikes.  The union movement served the ground for women to arise as political leaders.

The articles study brain development after birth from a socioeconomic, environmental, dietary, social class, and strata points of view. In 2004, researcher Brenda Jones Harden explores developmental procedures at cognitive levels in â€Å"Safety and Stability for Foster Children: A Developmental Perspective† (Harden, 2004). Phyllis Porter’s 2007 â€Å"Early Brain Development: What parents and caregivers need to know!† argues that children brought up in environmentally poor households like unmaintained orphanages become familiar to less sounds, colors, images, socializations, and visions. Jednorà ³g, et al, wrote â€Å"The influence of socioeconomic status on children’s brain structure† in 2012 to determine the effect of parental SES (Socioeconomic Status) on children’s brain development (Jednorà ³g, et al., 2012).

Lieducation in preliterate societies Essay Example for Free

Lieducation in preliterate societies Essay Education, History of, theories, methods, and administration of schools and other agencies of information from ancient times to the present. Education developed from the human struggle for survival and enlightenment. It may be formal or informal. Informal education refers to the general social process by which human beings acquire the knowledge and skills needed to function in their culture. Formal education refers to the process by which teachers instruct students in courses of study within institutions. Before the invention of reading and writing, people lived in an environment in which they struggled to survive against natural forces, animals, and other humans. To survive, preliterate people developed skills that grew into cultural and educational patterns. For a particular group’s culture to continue into the future, people had to transmit it, or pass it on, from adults to children. The earliest educational processes involved sharing information about gathering food and providing shelter; making weapons and other tools; learning language; and acquiring the values, behavior, and religious rites or practices of a given culture. Through direct, informal education, parents, elders, and priests taught children the skills and roles they would need as adults. These lessons eventually formed the moral codes that governed behavior. Since they lived before the invention of writing, preliterate people used an oral tradition, or story telling, to pass on their culture and history from one generation to the next. By using language, people learned to create and use symbols, words, or signs to express their ideas. When these symbols grew into pictographs and letters, human beings created a written language and made the great cultural leap to literacy. IIIEDUCATION IN ANCIENT AFRICA AND ASIA In ancient Egypt, which flourished from about 3000 BC to about 500 BC, priests in temple schools taught not only religion but also the principles of writing, the sciences, mathematics, and architecture. Similarly in India, priests conducted most of the formal education. Beginning in about 1200 BC Indian priests taught the principles of the Veda, the sacred texts of Hinduism, as well as science, grammar, and philosophy. Formal education in China dates to about 2000 BC, though it thrived particularly during the Eastern Zhou Dynasty, from 770 to 256 BC (see China: The Eastern Zhou). The curriculum stressed philosophy, poetry, and religion, in accord with the teachings of Confucius, Laozi (Lao-tzu), and other philosophers. IVEDUCATION IN ANCIENT GREECE Historians have looked to ancient Greece as one of the origins of Western formal education. The Iliad and the Odyssey, epic poems attributed to Homer and written sometime in the 8th century BC, created a cultural tradition that gave the Greeks a sense of group identity. In their dramatic account of Greek struggles, Homer’s epics served important educational purposes. The legendary Greek warriors depicted in Homer’s work, such as Agamemnon, Odysseus, and Achilles, were heroes who served as models for the young Greeks. Ancient Greece was divided into small and often competing city-states, or poleis, such as Athens, Sparta, and Thebes. Athens emphasized a humane and democratic society and education, but only about one-third of the people in Athens were free citizens. Slaves and residents from other countries or city-states made up the rest of the population. Only the sons of free citizens attended school. The Athenians believed a free man should have a liberal education in order to perform his civic duties and for his own personal development. The education of women depended upon the customs of the particular Greek city-state. In Athens, where women had no legal or economic rights, most women did not attend school. Some girls, however, were educated at home by tutors. Slaves and other noncitizens had either no formal education or very little. Sparta, the chief political enemy of Athens, was a dictatorship that used education for military training and drill. In contrast to Athens, Spartan girls received more schooling but it was almost exclusively athletic training to prepare them to be healthy mothers of future Spartan soldiers. In the 400s BC, the Sophists, a group of wandering teachers, began to teach in Athens. The Sophists claimed that they could teach any subject or skill to anyone who wished to learn it. They specialized in teaching grammar, logic, and rhetoric, subjects that eventually formed the core of the liberal arts. The Sophists were more interested in preparing their students to argue persuasively and win  arguments than in teaching principles of truth and morality. Unlike the Sophists, the Greek philosopher Socrates sought to discover and teach universal principles of truth, beauty, and goodness. Socrates, who died in 399 BC, claimed that true knowledge existed within everyone and needed to be brought to consciousness. His educational method, called the Socratic method, consisted of asking probing questions that forced his students to think deeply about the meaning of life, truth, and justice. In 387 BC Plato, who had studied under Socrates, established a school in Athens called the Academy. Plato believed in an unchanging world of perfect ideas or universal concepts. He asserted that since true knowledge is the same in every place at every time, education, like truth, should be unchanging. Plato described his educational ideal in the Republic, one of the most notable works of Western philosophy. Plato’s Republic describes a model society, or republic, ruled by highly intelligent philosopher-kings. Warriors make up the republic’s second class of people. The lowest class, the workers, provide food and the other products for all the people of the republic. In Plato’s ideal educational system, each class would receive a different kind of instruction to prepare for their various roles in society. In 335 BC Plato’s student, Aristotle, founded his own school in Athens called the Lyceum. Believing that human beings are essentially rational, Aristotle thought people could discover natural laws that governed the universe and then follow these laws in their lives. He also concluded that educated people who used reason to make decisions would lead a life of moderation in which they avoided dangerous extremes. In the 4th century BC Greek orator Isocrates developed a method of education designed to prepare students to be competent orators who could serve as government officials. Isocrates’s students studied rhetoric, politics, ethics, and history. They examined model orations and practiced public speaking. Isocrates’s methods of education directly influenced such Roman educational theorists as Cicero and Quintilian. VEDUCATION IN ANCIENT ROME While the Greeks were developing their civilization in the areas surrounding the eastern Mediterranean Sea, the Romans were gaining control of the Italian peninsula and areas of the western Mediterranean. The Greeks’ education focused on the study of philosophy. The Romans, on the other hand, were preoccupied with war, conquest, politics, and civil administration. As in Greece, only a minority of Romans attended school. Schooling was for those who had the money to pay tuition and the time to attend classes. While girls from wealthy families occasionally learned to read and write at home, boys attended a primary school, called aludus. In secondary schools boys studied Latin and Greek grammar taught by Greek slaves, called pedagogues. After primary and secondary school, wealthy young men often attended schools of rhetoric or oratory that prepared them to be leaders in government and administration. Cicero, a 1st century BC Roman senator, combined Greek and Roman ideas on how to educate orators in his book De Oratore. Like Isocrates, Cicero believed orators should be educated in liberal arts subjects such as grammar, rhetoric, logic, mathematics, and astronomy. He also asserted that they should study ethics, military science, natural science, geography, history, and law. Quintilian, an influential Roman educator who lived in the 1st century AD, wrote that education should be based on the stages of individual development from childhood to adulthood. Quintilian devised specific lessons for each stage. He also advised teachers to make their lessons suited to the student’s readiness and ability to learn new material. He urged teachers to motivate students by making learning interesting and attractive. VIANCIENT JEWISH EDUCATION Education among the Jewish people also had a profound influence on Western learning. The ancient Jews had great respect for the printed word and believed that God revealed truth to them in the Bible. Most information on ancient Jewish goals and methods of education comes from the Bible and the Talmud, a book of religious and civil law. Jewish religious leaders, known as rabbis, advised parents to teach their children religious beliefs, law, ethical practices, and vocational skills. Both boys and girls were introduced to religion by studying the Torah, the most sacred document of Judaism. Rabbis taught in schools within synagogues, places of worship and religious study. VIIMEDIEVAL EDUCATION During the Middle Ages, or the medieval period, which lasted roughly from the 5th to the 15th century, Western society and education were heavily shaped by Christianity, particularly the Roman Catholic Church. The Church operated parish, chapel, and monastery schools at the elementary level. Schools in monasteries and cathedrals offered secondary education. Much of the teaching in these schools was directed at learning Latin, the old Roman language used by the church in its ceremonies and teachings. The church provided some limited opportunities for the education of women in religious communities or convents. Convents had libraries and schools to help prepare nuns to follow the religious rules of their communities. Merchant and craft guilds also maintained some schools that provided basic education and training in specific crafts. Knights received training in military tactics and the code of chivalry. As in the Greek and Roman eras, only a minority of people went to school during the medieval period. Schools were attended primarily by persons planning to enter religious life such as priests, monks, or nuns. The vast majority of people were serfs who served as agricultural workers on the estates of feudal lords. The serfs, who did not attend school, were generally illiterate (see Serfdom). In the 10th and early 11th centuries, Arabic learning had a pronounced influence on Western education. From contact with Arab scholars in North Africa and Spain, Western educators learned new ways of thinking about mathematics, natural science, medicine, and philosophy. The Arabic number system was especially important, and became the foundation of Western arithmetic. Arab scholars also preserved and translated into Arabic the works of such influential Greek scholars as Aristotle, Euclid, Galen, and Ptolemy. Because many of these works had disappeared from Europe by the Middle Ages, they might have been lost forever if Arab scholars such as Avicenna and Averroes had not preserved them. In the 11th century medieval scholars developed Scholasticism, a philosophical and educational movement that used both human reason and revelations from the Bible. Upon encountering the works of Aristotle and other Greek philosophers from Arab scholars, the Scholastics attempted to reconcile Christian theology with Greek philosophy. Scholasticism reached its high point in the Summa Theologiae of Saint Thomas Aquinas, a 13th century Dominican theologian who taught at the University of Paris. Aquinas reconciled the authority of religious faith, represented by the Scriptures, with Greek reason, represented by Aristotle. Aquinas described the teacher’s vocation as one that combines faith, love, and learning. The work of Aquinas and other Scholastics took place in the medieval institutions of higher education, the universities. The famous European universities of Paris, Salerno, Bologna, Oxford, Cambridge, and Padua grew out of the Scholastics-led intellectual revival of the 12th and 13th centuries. The name university comes from the Latin word universitas, or associations, in reference to the associations that students and teachers organized to discuss academic issues. Medieval universities offered degrees in the liberal arts and in professional studies such as theology, law, and medicine. VIIIEDUCATION DURING THE RENAISSANCE The Renaissance, or rebirth of learning, began in Europe in the 14th century and reached its height in the 15th century. Scholars became more interested in the humanist features—that is, the secular or worldly rather than the religious aspects—of the Greek and Latin classics. Humanist educators found their models of literary style in the classics. The Renaissance was a particularly powerful force in Italy, most notably in art, literature, and architecture. In literature, the works of such Italian writers as Dante Aleghieri, Petrarch, and Giovanni Boccaccio became especially important. Humanist educators designed teaching methods to prepare well-rounded, liberally educated persons. Dutch humanist Desiderius Erasmus was particularly influential. Erasmus believed that understanding and conversing about the meaning of literature was more important than memorizing it, as had been required at many of the medieval religious schools. He advised teachers to study such fields as archaeology, astronomy, mythology, history, and Scripture. The invention of the printing press in the mid-15th century made books more widely available and increased literacy rates (see Printing). But school attendance did not increase greatly during the Renaissance. Elementary schools educated middle-class children while lower-class children received little, if any, formal schooling. Children of the nobility and upper classes attended humanist secondary schools. Educational opportunities for women improved slightly during the Renaissance, especially for the upper classes. Some girls from wealthy families attended schools of the royal court or received private lessons at home. The curriculum studied by young women was still based on the belief that only certain subjects, such as art, music, needlework, dancing, and poetry, were suited for females. For working-class girls, especially rural peasants, education was still limited to training in household duties such as cooking and sewing. IXEDUCATION DURING THE PROTESTANT REFORMATION The religious Reformation of the 16th century marked a decline in the authority of the Catholic Church and contributed to the emergence of the middle classes in Europe. Protestant religious reformers, such as John Calvin, Martin Luther, and Huldreich Zwingli, rejected the authority of the Catholic pope and created reformed Christian, or Protestant, churches. In their ardent determination to instruct followers to read the Bible in their native language, reformers extended literacy to the masses. They established vernacular primary schools that offered a basic curriculum of reading, writing, arithmetic, and religion for children in their own language. Vernacular schools in England, for example, used English to teach their pupils. As they argued with each other and with the Roman Catholics on religious matters, Protestant educators wrote catechisms—primary books that summarized their religious doctrine—in a question and answer format. While the vernacular schools educated both boys and girls at the primary level, upper-class boys attended preparatory and secondary schools that continued to emphasize Latin and Greek. The gymnasium in Germany, the Latin grammar school in England, and the lycee in France were preparatory schools that taught young men the classical languages of Latin and Greek required to enter universities. Martin Luther believed the state, family, and school, along with the church, were leaders of the Reformation. Since the family shaped children’s character, Luther encouraged parents to teach their children reading and religion. Each family should pray together, read the Bible, study the catechism, and practice a useful trade. Luther believed that government should assist schools in educating literate, productive, and religious citizens. One of Luther’s colleagues, German religious reformer Melanchthon, wrote the school code for the German region of Wurttemberg, which became a model for other regions of Germany and influenced education throughout Europe. According to this code, the government was responsible for supervising schools and licensing teachers. The Protestant reformers retained the dual-class school system that had developed in the Renaissance. Vernacular schools provided primary instruction for the lower classes, and the various classical humanist and Latin grammar schools prepared upper-class males for higher education. XEDUCATIONAL THEORY IN THE 17TH CENTURY Educators of the 17th century developed new ways of thinking about education. Czech education reformer Jan Komensky, known as Comenius, was particularly influential. A bishop of the Moravian Church, Comenius escaped religious persecution by taking refuge in Poland, Hungary, Sweden, and The Netherlands. He created a new educational philosophy called Pansophism, or universal knowledge, designed to bring about worldwide understanding and peace. Comenius advised teachers to use children’s senses rather than memorization in instruction. To make learning interesting for children, he wrote The Gate of Tongues Unlocked (1631), a book for teaching Latin in the student’s own language. He also wrote Orbis Sensualium Pictus (1658; The Visible World in Pictures, 1659) consisting of illustrations that labeled objects in both their Latin and vernacular names. It was one of the first illustrated books written especially for children. The work of English philosopher John Locke influenced education in Britain and North America. Locke examined how people acquire ideas in An Essay Concerning Human Understanding (1690). He asserted that at birth the human mind is a blank slate, or tabula rasa, and empty of ideas. We acquire knowledge, he argued, from the information about the objects in the world that our senses bring to us. We begin with simple ideas and then combine them into more complex ones. Locke believed that individuals acquire knowledge most easily when they first consider simple ideas and then gradually combine them into more complex ones. In Some Thoughts Concerning Education (1697), Locke recommended practical learning to prepare people to manage their social, economic, and political affairs efficiently. He believed that a sound education began in early childhood and insisted that the teaching of reading, writing, and arithmetic be gradual and cumulative. Locke’s curriculum included conversational learning of foreign languages, especially French, mathematics, history, physical education, and games. XIEDUCATION DURING THE ENLIGHTENMENT The Age of Enlightenment in the 18th century produced important changes in education and educational theory. During the Enlightenment, also called the Age of Reason, educators believed people could improve their lives and society by using their reason, their powers of critical thinking. The Enlightenment’s ideas had a significant impact on the American Revolution (1775-1783) and early educational policy in the United States. In particular, American philosopher and scientist Benjamin Franklin emphasized the value of utilitarian and scientific education in American schools. Thomas Jefferson, the third president of the United States, stressed the importance of civic education to the citizens of a democratic nation. The Enlightenment principles that considered education as an instrument of social reform and improvement remain fundamental characteristics of American education policy. XIIEDUCATION IN THE 19TH CENTURY The foundations of modern education were established in the 19th century. Swiss educator Johann Heinrich Pestalozzi, inspired by the work of French philosopher Jean Jacques Rousseau, developed an educational method based on the natural world and the senses. Pestalozzi established schools in Switzerland and Germany to educate children and train teachers. He affirmed that schools should resemble secure and loving homes. Like Locke and Rousseau, Pestalozzi believed that thought began with sensation and that teaching should use the senses. Holding that children should study the objects in their natural environment, Pestalozzi developed a so-called â€Å"object lesson† that involved exercises in learning form, number, and language. Pupils determined and traced an object’s form, counted objects, and named them. Students progressed from these lessons to exercises in drawing, writing, adding, subtracting, multiplying, dividing, and reading. Pestalozzi employed the following principles in teaching: (1) begin with the concrete object before introducing abstract concepts; (2) begin with the immediate environment before dealing with what is distant and remote; (3) begin with easy exercises before introducing complex ones; and (4) always proceed gradually, cumulatively, and slowly. American educator Henry Barnard, the first U. S. Commissioner of Education, introduced Pestalozzi’s ideas to the United States in the late 19th century. Barnard also worked for the establishment of free public high schools for students of all classes of American society. German philosopher Johann Herbart emphasized moral education and designed a highly structured teaching technique. Maintaining that education’s primary goal is moral development, Herbart claimed good character rested on knowledge while misconduct resulted from an inadequate education. Knowledge, he said, should create an â€Å"apperceptive mass†Ã¢â‚¬â€a network of ideas—in a person’s mind to which new ideas can be added. He wanted to include history, geography, and literature in the school curriculum as well as reading, writing, and arithmetic. Based on his work, Herbart’s followers designed a five-step teaching method: (1) prepare the pupils to be ready for the new lesson, (2) present the new lesson, (3) associate the new lesson with ideas studied earlier, (4) use examples to illustrate the lesson’s major points, and (5) test pupils to ensure they had learned the new lesson. AKindergarten German educator Friedrich Froebel created the earliest kindergarten, a form of preschool education that literally means â€Å"child’s garden† in German. Froebel, who had an unhappy childhood, urged teachers to think back to their own childhoods to find insights they could use in their teaching. Froebel studied at Pestalozzi’s institute in Yverdon, Switzerland, from 1808 to 1810. While agreeing with Pestalozzi’s emphasis on the natural world, a kindly school atmosphere, and the object lesson, Froebel felt that Pestalozzi’s method was not philosophical enough. Froebel believed that every child’s inner self contained a spiritual essence—a spark of divine energy—that enabled a child to learn independently. In 1837 Froebel opened a kindergarten in Blankenburg with a curriculum that featured songs, stories, games, gifts, and occupations. The songs and stories stimulated the imaginations of children and introduced them to folk heroes and cultural values. Games developed children’s social and physical skills. By playing with each other, children learned to participate in a group. Froebel’s gifts, including such objects as spheres, cubes, and cylinders, were designed to enable the child to understand the concept that the object represented. Occupations consisted of materials children could use in building activities. For example, clay, sand, cardboard, and sticks could be used to build castles, cities, and mountains. Immigrants from Germany brought the kindergarten concept to the United States, where it became part of the American school system. Margarethe Meyer Schurz opened a German-language kindergarten in Watertown, Wisconsin, in 1855. Elizabeth Peabody established an English-language kindergarten and a training school for kindergarten teachers in Boston, Massachusetts, in 1860. William Torrey Harris, superintendent of schools in St. Louis, Missouri, and later a U. S. commissioner of education, made the kindergarten part of the American public school system. BSocial Darwinism British sociologist Herbert Spencer strongly influenced education in the mid-19th century with social theories based on the theory of evolution developed by British naturalist Charles Darwin. Spencer revised Darwin’s biological theory into social Darwinism, a body of ideas that applied the theory of evolution to society, politics, the economy, and education. Spencer maintained that in modern industrialized societies, as in earlier simpler societies, the â€Å"fittest† individuals of each generation survived because they were intelligent and adaptable. Competition caused the brightest and strongest individuals to climb to the top of the society. Urging unlimited competition, Spencer wanted government to restrict its activities to the bare minimum. He opposed public schools, claiming that they would create a monopoly for mediocrity by catering to students of low ability. He wanted private schools to compete against each other in trying to attract the brightest students and most capable teachers. Spencer’s social Darwinism became very popular in the last half of the 19th century when industrialization was changing American and Western European societies. Spencer believed that people in industrialized society needed scientific rather than classical education. Emphasizing education in practical skills, he advocated a curriculum featuring lessons in five basic human activities: (1) those needed for self-preservation such as health, diet, and exercise; (2) those needed to perform one’s occupation so that a person can earn a living, including the basic skills of reading, writing, computation, and knowledge of the sciences; (3) those needed for parenting, to raise children properly; (4) those needed to participate in society and politics; and (5) those needed for leisure and recreation. Spencer’s ideas on education were eagerly accepted in the United States. In 1918 the Cardinal Principles of Secondary Education, a report issued by the National Education Association, used Spencer’s list of activities in its recommendations for American education. XIIINATIONAL SYSTEMS OF EDUCATION In the 19th century, governments in the United Kingdom, Germany, France, Italy, and other European countries organized national systems of public education. The United States, Canada, Argentina, Uruguay, and other countries in North and South America also established national education systems based largely on European models. AIn the United Kingdom. The Church of England and other churches often operated primary schools in the United Kingdom, where students paid a small fee to study the Bible, catechism, reading, writing, and arithmetic. In 1833 the British Parliament passed a law that gave some government funds to these schools. In 1862 the United Kingdom established a school grant system, called payment by results, in which schools received funds based on their students’ performance on reading, writing, and arithmetic tests. The Education Act of 1870, called the Forster Act, authorized local government boards to establish public board schools. The United Kingdom then had two schools systems: board schools operated by the government and voluntary schools conducted by the churches and other private organizations. In 1878 the United Kingdom passed laws that limited child labor in factories and made it possible for more children to attend school. To make schooling available to working-class children, many schools with limited public and private funds used monitorial methods of instruction. Monitorial education, developed by British educators Joseph Lancaster and Andrew Bell, used student monitors to conduct lessons. It offered the fledgling public education system the advantage of allowing schools to hire fewer teachers to instruct the large number of new students. Schools featuring monitorial education used older boys, called monitors, who were more advanced in their studies, to teach younger children. Monitorial education concentrated on basic skills—reading, writing, and arithmetic—that were broken down into small parts or units. After a monitor had learned a unit—such as spelling words of two or three letters that began with the letter A—he would, under the master teacher’s supervision, teach this unit to a group of students. By the end of the 19th century, the monitorial system was abandoned in British schools because it provided a very limited education. BIn Russia Russian tsar Alexander II initiated education reforms leading to the Education Statute of 1864. This law created zemstvos, local government units, which operated primary schools. In addition to zemstvo schools, the Russian Orthodox Church conducted parish schools. While the number of children attending school slowly increased, most of Russia’s population remained illiterate. Peasants often refused to send their children to school so that they could work on the farms. More boys attended school than girls since many peasant parents considered female education unnecessary. Fearing that too much education would make people discontented with their lives, the tsar’s government provided only limited schooling to instill political loyalty and religious piety. CIn the United States Before the 19th century elementary and secondary education in the United States was organized on a local or regional level. Nearly all schools operated on private funds exclusively. However, beginning in the 1830s and 1840s, American educators such as Henry Barnard and Horace Mann argued for the creation of a school system operated by individual states that would provide an equal education for all American children. In 1852 Massachusetts passed the first laws calling for free public education, and by 1918 all U. S. states had passed compulsory school attendance laws. See Public Education in the United States. XIVEDUCATION IN THE TWENTIETH CENTURY At the beginning of the 20th century, the writings of Swedish feminist and educator Ellen Key influenced education around the world. Key’s book Barnets arhundrade (1900; The Century of the Child,1909) was translated into many languages and inspired so-called progressive educators in various countries. Progressive education was a system of teaching that emphasized the needs and potentials of the child, rather than the needs of society or the principles of religion. Among the influential progressive educators were Hermann Lietz and Georg Michael Kerschensteiner of Germany, Bertrand Russell of England, and Maria Montessori of Italy. AMontessori Montessori’s methods of early childhood education have become internationally popular. Trained in medicine, Montessori worked with developmentally disabled children early in her career. The results of her work were so effective that she believed her teaching methods could be used to educate all children. In 1907 Montessori established a children’s school, the Casa dei Bambini (Children’s House), for poor children from the San Lorenzo district of Rome. Here she developed a specially prepared environment that featured materials and activities based on her observations of children. She found that children enjoy mastering specific skills, prefer work to play, and can sustain concentration. She also believed that children have a power to learn independently if provided a properly stimulating environment. Montessori’s curriculum emphasized three major classes of activity: (1) practical, (2) sensory, and (3) formal skills and studies. It introduced children to such practical activities as setting the table, serving a meal, washing dishes, tying and buttoning clothing, and practicing basic social manners. Repetitive exercises developed sensory and muscular coordination. Formal skills and subjects included reading, writing, and arithmetic. Montessori designed special teaching materials to develop these skills, including laces, buttons, weights, and materials identifiable by their sound or smell. Instructors provided the materials for the children and demonstrated the lessons but allowed each child to independently learn the particular skill or behavior. In 1913 Montessori lectured in the United States on her educational method.
