モデルを利用した電気教材の学習とその効果

The abstract phenomenon on both heat and electricity has been easily understood in most pupils by use of some models as current of water.
Some models of the macroscopic phenomenon of electricity had been used as the closed circuits of water in the pipes. We devised the new models according to electric circuits by revise of these models, and investigated the effects of our models in learning through experimental education in second year of junior high school.
Considerable effects of model methods in the teaching on materials of electricity were regarded by analyzing the data of the post-test and the retention-test stutistically.
