Abstract This paper centers around the discussion on the metamorphism of sodium hydroxide and incorporates relevant properties of acids, alkalis and salts, with the view to integrating the ideas and concepts used in knowledge consolidation as well as solving material transformation problems throughout the entire stretch of classroom experiments and explorations. In doing so, this paper is expected to help students experience the detailed processes of model cognition from the dimensions of conceptual comprehension, modeling, learning activity, actual problems and model evaluation. Furthermore, the method of experimental study was adopted herein to resolve the cognitive conflicts faced by students, as well as in turn rectify and improve the model, so as to construct a mental model based on knowledge consolidation and solving material transformation problems, and enhance core competencies in chemistry-related courses.
