Pnömatik sistem modeli ile basit elektrik devresinde lambanın hangi durumlarda işık vereceğinin öğretilmesi

The topic of electricity is included in science and physics curricula because of the importance of electricity and its use in daily life. The understanding of a simple electric circuit as the basic system is extremely important for the teaching of electrical concepts. Therefore analogical relationship have been formed with “air pump-battery, transparent plastic hose-power line, valve-switch, plastic balloon-light bulb, inflating plastic balloon-the light emitting bulb” in the Pneumatic System Model. Also the differences between the source and target concepts in the PSM have been expressed for preventing misconception. An experiment-based analogical Pneumatic System Model (PSM) used to teach the 5th students (11 year-old), the variables having an effect on the brightness of a light bulb in a simple electric circuit has been revised and its suitability and operability for teaching of the light emitting bulb conditions in a simple electric circuit, and resolving the faulty circuits have been discussed.
