摘要
文章基于化学学科理解的视角以“认识碳酸钠的溶解性”为例,基于研究碳酸钠在不同溶剂中的溶解性情况、碳酸钠溶于水的吸放热情况、碳酸钠的溶解性随温度的变化情况以及比较碳酸钠和氢氧化钠的溶解性与应用等本原性问题进行学科理解的复习,帮助学生对“溶液”核心概念进行结构化思维,以达到提升核心素养的目的。
Based on the perspective of chemical discipline understanding,taking“understanding the solubility of sodium carbonate”as an example,this paper reviews the discipline understanding based on the study of the solubility of sodium carbonate in different solvents,the heat absorption and release of sodium carbonate dissolved in water,the change of sodium carbonate solubility with temperature,and the comparison of the solubility and application of sodium carbonate and sodium hydroxide,help students think structurally about the core concept of“solution”,so as to improve their core literacy.
