Thermal stability of inorganic substances is one of the difficulties in teaching and learning chemistry of the elements. In this paper, representative examples are selected to qualitatively analyze various factors affecting the thermal stability of inorganic substances and then the fundamental factors are summarized from the structural perspective. This learning process can help learners to construct the knowledge for understanding the thermal stability of inorganic substances and establish a relevant cognitive model. By taking "the thermal stability of inorganic substances" as the knowledge carrier, this paper demonstrates the "knowledge construction" learning mode, and provides some valuable references for the classroom teaching reform of chemistry of the elements.

Key words: Chemistry of the elements, Thermal stability, Knowledge construction, Classroom teaching reform
