基于认识模型建构的电解池复习教学

Review Teaching of Electrolytic Cell Based on Construction of Cognitive Model

通过分析电解池学习的知识要求和学生学习电解池知识存在的困难,从原理、装置和任务3个维度提出电解池认识模型,在此基础上设计了高二电解池复习教学,并进行了实践。结果表明基于该模型进行复习教学的设计和实施有利于提高学生解决电解池问题的能力,并在教学反思中总结了存在的不足,指明了后续教学的方向。

Through analyzing the knowledge requirements of electrolytic cell and the possible learning difficulty for students,this paper proposed the cognitive model of electrolytic cell from dimensions of principle,device and task,and applied the cognitive model in the review teaching of electrolytic cells in grade two of senior high school.The results showed that the design and implementation of the review teaching based on the cognitive model could help improve the students’ ability to solve the problems of electrolytic pool.And in the teaching reflection,this paper summed up the existing problems,and pointed out the direction of the follow-up teaching.
