Background and purpose : Chemistry examinations can favour the deployment of algorithmic procedures like Le Chatelier’s Principle (LCP) rather than reasoning using chemical principles. This study… (More)
Chemistry students’ explanations of ionisation energy phenomena often involve a number of non-scientific or inappropriate ideas being used to form causality arguments. Research has attributed this to… (More)
ABSTRACTThe effect of intervention activities on the chemistry content knowledge of 92 preservice chemistry teachers (PSCT) was examined via a pre and post true/false with confidence level test… (More)
Literature identifies the insufficiency of Le Chatelier’s principle and research describes a number of problems that students have in explaining and describing chemical equilibrium systems. Hence in… (More)
