DESCRIPTION OF CONTENTS:

In this study, two teaching methods aiming at improving the learning of highly abstract and complex content of chemistry in lower secondary school have been examined. One is a method based on developmental psychology and the other is a “three-cycle” method based on the distinction of school chemistry into macroscopic, submicroscopic and representational levels. The macro cycle did not include chemical notation, as well as the concepts of molecules and atoms. The representational cycle covered the same course material by adding chemical formulae and equations. The submicro cycle introduced atomic and molecular structure, and stoichiometry. The experimental groups scored higher at tests, mainly on the theoretical questions, but the largest positive effect was shown to be induced by the three-cycle method.

COMMENTS ON THIS DOCUMENT:

Research in chemistry education is able to produce a remarkable improvement in learning chemistry, focusing on teaching methods enriched with features based on psychological theory.
The paper also contains remarkable suggestions for teachers of secondary school.
