摘要: 无机物溶解性是元素化学教与学中的难点之一。本文选取教学中的代表性实例,通过分析、比较和归纳影响无机物溶解性的因素,对其进行本源性理解,建构一种便于学习者理解无机物溶解性的认识模型。基于“无机物溶解性”这一知识载体深入探讨“建构式”学习模式在元素化学教学中的应用。

Abstract: Solubility of inorganic substances is one of the difficulties in teaching and learning elemental chemistry. This article selects representative examples and provides a fundamental understanding of the solubility of inorganic substances by means of analyzing, comparing, and summarizing its influencing factors. And thus a cognitive model is constructed to facilitate learners’ understanding. Based on the knowledge carrier of “the solubility of inorganic substances”, this paper explores the application of the “knowledge construction” learning mode in elemental chemistry teaching.

Key words: Elemental chemistry, Solubility of inorganic substances, Knowledge construction, Cognitive model
