Abstract

USING CRITICAL ASPECTS TO DESIGN CHEMISTRY LESSONS: A LEARNING STUDY WITH COMBINED SCIENCE TEACHERS

Strand: Pedagogy

A group of nine high school Combined Science teachers with the support of two learning study facilitators explored the critical aspects of teaching Chemistry topics of Acids and Bases in the first cycle and Separating Mixtures in the second cycle. In each cycle, teachers and facilitators designed a pre-test to find out what students needed to learn, and that led to the identification of the critical aspects that were incorporated into the lesson plan of each research lesson. In the first cycle, students found it critical to notice a change of pH through observation of colour change from acidic to neutral for the treatment of wastewater. In the second cycle, knowing the physical properties of substances in a mixture is critical to understanding why and how the substances can separate. The research findings show that there was an increase in the discernment of these critical aspects in post-research lessons in both cycles.
