The transformation of the understanding degree of an energy concept in the Japanese school education grade

Abstract

The questionaires were sent out on the energy concept in the school education grade. And, the disparity in sexes, the transfigration by study, and the understanding of an energy concept are investigated, The recults are as follows. 1. The increasing rate of right answers from sixth to ninth drade is larger than that ninth to twelfth grade. Especially, when the answers were examined one by one, a junior high school boy can able to understand and recognize about an energy form, an energy preservation, and an energy change are cleared. 2. Comparing the pattern of an energy recognition of a senior high school boy with a junior high school boy, a junior high school girl, or a senior high school girl, a capable difference cannot be observed in six to fourteen questions, one to fourteen questions, or seven to fourteen questions. On account of this reason, a junior high school boy can study the nature phenomena through an energy concept as well as a senior high school boy, but a senior high school girl can not study on the most of the same subject. 3. In the physical and chemical lines, a capable difference can not be observed within a junior high school boy and a senior high school boy, but a difference can be observed in the biological geological lines. This fact indicates that the formation of an energy concept to a boy at early school grade through the physical and chemical lines is easyer than through the biological and geological lings. Therefore, an energy concept to a girl through the physical and chemical lines is not effective both at junior and senior high school grade. An energy concept can be studied only at senior high school grade through the biological and geological lines.
