Teachers' conceptual subject matter knowledge of stoichiometry is a global concern. Such knowledge is contextually dependent, as is the feasibility of attaining particular outcomes during in-service teacher education workshops. In an attempt to understand what is feasible in various contexts, I explore the relationships between South African…

This study explored the perceptions of teachers and learners regarding the use of Process Oriented Guided Learning Inquiry Learning (POGIL) to teach stoichiometry. A qualitative case study was carried out at two conveniently and purposively sampled township schools in Pretoria, South Africa. For this purpose, two Grade 11 physical sciences classes…

Students' inaccurate ideas about what is represented by chemical equations and concepts underlying stoichiometry are well documented; however, there are few classroom-ready instructional solutions to help students build scientifically accurate ideas about these topics central to learning chemistry. An intervention (two inquiry-based activities)…
