Investgating into Improvement of Chemistry Experiments in Relation to Its Depth for the Concept of Partical of Matter Author: Yong-hwa Yang, Cheng-hsia Wang


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).
