Development of Teaching Materials to Support Learning about Lenses in the Classroom

Abstract

Many junior high school students have difficulties in their understanding of learning about lenses. Part of the difficulty may be seen to be derived from laboratory instruments used in learning about lenses. We developed an experiment tool designer to lead to an understanding of the principles of lenses and usage of the optical instruments. In a class using this experimental tool, it was observed that students conducted experiments over and over. Effects of the experimental tool and the active learning program were evaluated.
