基于POE教学策略和比较思维的教学——以“碳酸钠和碳酸氢钠的性质”为例

Teaching of “Properties of Sodium Carbonate and Sodium Bicarbonate” Based on POE Teaching Strategy and Comparative Thinking

以POE教学策略组织教学,尝试用比较思维方法学习碳酸钠、碳酸氢钠的性质,并设计多组实验比较碳酸钠、碳酸氢钠的结构、性质等,以期学生学会用比较思维和化学科学研究的一般步骤。

POE teaching strategy was used to organize teaching, and the natures of sodium carbonate and sodium bicarbonate were studied with comparative thinking method. Multiple experiments were designed to compare the structures and properties of sodium carbonate and sodium bicarbonate, so as to help learners learn the general steps of comparative thinking and chemical scientific research.
