本研究收集並分析國內外（中、美、英、日）各階段（小學、國中及高中）自然科學教材中有關「酸與鹼」主題概念之實驗，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「酸與鹼」主題單元實驗活動與概念的銜接問題。特別針對「酸與鹼」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 is a research project which investigates into the improvement of experi-mental activities in the field of chemistry from primary school through senior high school. The correlation 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 level. (c) The level of cognitive development of the students. (d) Previously acquired learning of the students. (e) Safety, simplicity, economy (both of money and of class time). The key experimental activities of the acid-base concept were reviewed on major curricula (R.O.C., Japan, U.S.A., England).
