単純電気回路に関する小・中学生の考え方の再検討 : 事象面接法を通して

抄録

The Osborne models (Unipolar model, Attenuation model, Clashing model, Scientific model) are widely accepted in the field of study about children's ideas about a simple electric circuit. There are many studies which are based on Osborne's study. But there are few studies which reconsider the models proposed jointly by Osborne and his colleagues. The aim of this study is to reconsider children's ideas as proposed by Osborne and his colleagues. We conducted interviews to determine children's ideas about electric current. An electric bulb or a motor is used as a load of a circuit. The subjects were selected from the 1st, 3rd, and 5th graders of primary School and 7th and 9th graders of the lower secondary school. The number of samples was ten per grade. The following suggestions were obtained from the investigation : 1. Students of all grades can use primitive ideas about current. 2. Some of the children's ideas could not be predicted from the Osborne models. 3. The difference of load does not necessarily lead the children to acquire different ideas
