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.
