Abstract

<p>We examine the effect of providing external resources that can be manipulated by students on the formation of scientific concepts. Observations were carried out during a lesson on the path of a typhoon. Students were divided into one experimental group and one control group. Weather satellite pictures were prepared for both groups, whereas clear sheets and colored stickers were provided only to the experimental group as external resources. The result was that the experimental group was more effective in forming the scientific concept. In the experimental group, many students used the clear sheets and we could see that they talked about noticing the visualization of the path of the typhoon by using those sheets. In addition, we found many utterances of the students' comparing the path of the typhoon they had obtained against that of other students and discussing it with others by superimposing clear sheets. This suggests that the operatability of the external resources had enhanced the learners' interest in using them. Since the answer to the question could be visualized by the operation of those external resources, it was easier for the learners to solve the question, which aided them in the efficient formation of the scientific concept.</p>
