本研究收集并分析中、美、英、日诸国之各阶段(小学至高中)的影响力较大自然科学教材中有关「能量」主题单元概念之实验活动,研讨其所包含的化学概念,建立其主题概念的发展顺序。分析与比较其所含的科学过程和科学态度,并探讨本主题单元实验活动与概念的衔接问题。特别针对有「量的处理」之实验活动进行评鉴,经由实验过程获得具体结果并提供建议。
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.
