Sažetak
In the course of learning chemistry, students develop various alternative concepts [1]. Development of such alternative concepts can exhibit far-reaching consequences on further chemical education. Consequently, in order to achieve a better quality in the teaching of chemistry, it is necessary to: 1. determine the types of pre-concepts that students have already developed prior to entering the elementary chemistry courses, 2. determine the types of alternative concepts that are developed by existing teaching strategies, 3. determine how and why alternative concepts are developed, 4. determine the relationship between student's higher cognitive skills and the ability to develop concepts. A cross-age study was performed with the intention to determine the alternative concepts that were developed by students in explaining and describing observed chemical change through the concept of a chemical equation. The experiments used were the simple and well-known experiments with the candle. The results obtained were correlated with teaching strategies exploited by chemistry teachers in teaching the concept of the chemical equation. [1] Nussbaum J.: Int. J. Sci.
