基于微粒观建构的化学教学策略——以“弱电解质的电离”为例

Chemical Teaching Strategies Based on Construction of Particle View——Taking “Weak Electrolyte Ionization” as an Example

采用文献研究、定量分析等方法,以"弱电解质的电离"为例,通过对学生已有微观知识的认识发展分析,在明确学生对弱电解质电离认知障碍的基础上,渗透基于微粒观建构的化学教学策略,培养学生从微观角度认识宏观物质的思维方法,促进其观念建构化学习方式的形成。

Using the methods of literature research and quantitative analysis,taking the＂weak electrolyte ionization＂for example,through the understanding of students for micro knowledge development analysis,and makeing clear students of weak electrolyte ionization on the basis of cognitive impairment,the paper explores how to penetrate into the chemistry teaching strategy based on particle view construction,how to train the student to know the macro material from the microscopic view of thinking methods so as to promote the idea to construct the formation of learning style.
