Lighten Learners’ Cognitive Load or Create Conceptual Understanding: Looking Beyond Le Chatelier’s Principle.
Year: 2026
Type: preprint
Abstract: Here we explore a novel approach to teaching the effect of temperature on exothermic and endothermic reactions. We contend that Le Chatelier’s Principle is best used as a predictive tool. Insights from teacher practice, personal experience and action research are shared. This narrative is a reflective professional journey supported by empirical evidence from action research (n = 17). The insights gained offer strategies to build conceptual understanding by applying Johnstone’s Triangle to reactions like the Haber process. We discuss an approach to making connections among the reaction profile, the overall equation and the Boltzmann distribution curve.
