A Comparative Study on Energy Concept Development and Slope for Elementary to Senior High Schools Author: Cheng-Hsia Wang, Yong-Hwa Yang

Abstract：

This is a study on the improvement of experimental activities in the chemistry curricula of primary school through senior high school. The correlation and the suitability of each experiment were evaluated according to the following criteria: (a) Data relevant to the concept for the particular learning Level, (b) Correlation of experiments for the same concept at different learning levels, (c) The level of cognitive development of the students, (d) Previously acquired learning of the students, and (e) Safety, simplicity and economy (both of money and of class time).
The key experimental activities of the energy concept in various major curricula (R. p. C., Japan, U. S. A., England) were reviewed.
