中小學科學課程中「物質的粒子概念」之研究

Abstract

本研究收集並分析國內外（中、美、英、日）各階段（小學至高中）有關「物質的粒子性」主題概念活動，研討實驗活動所包含的化學概念，建立主題概念的發展順序。分析與比較其所含的科學過程與科學態度，並探討本主題單元實驗活動與概念的銜接問題。特別針對「物質的粒子性」中有關量的處理之實驗活動進行評鑑，經由實做過程獲得具體結果並提供建議。

This research project investigates into the improvement of experimental acivities in the field of chemistry from primary school through senior high school. The cor-relation and suitability of each experiment was evaluated with the following points as basis: (a) Relevance of data produced 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. (e) Safety, simplicity, and economy (both of money and class time).The key experimental activities of the concept of particle of matter were reviewed on major curricula (R.O. C., U. S. A., England and Japan).
