摘要：

“无机物热稳定性”是元素化学内容教与学的难点之一。本文选取代表性实例，通过分析、比较和归纳影响无机物热稳定性的根本影响因素，对其进行结构化、本源化理解，构建认识无机物热稳定性的思维导图，建立无机物热稳定性的认识模型。以“无机物热稳定性”为知识载体，探讨知识“建构式”的学习模式在元素化学教学中的应用。

关键词: 元素化学, 热稳定性, 建构式学习, 课题教学改革

Abstract:

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
