The development of modules for the teaching of chemical equilibrium

Three modules on chemical equilibrium were developed as resource materials for a content‐cum‐methodology course in chemistry for intending teachers and also for general chemistry courses at the senior secondary and tertiary levels. The modules deal with the qualitative and quantitative aspects of gaseous, ionic, solubility, acid‐base and redox equilibria. The modules are based on research articles on the teaching and learning of chemical equilibrium and general science education research on misconceptions, conceptual difficulties and teaching strategies. The development of competence through assigned tasks was addressed. Use of these modules with 46 students on a methodology course in chemistry showed a significant development of competence in the knowledge and understanding, processes, problem‐solving and applications domains. The modules also reduced misconceptions in some aspects of equilibrium.
