基于问题的“四步法”在高中化学课堂中的应用——以《原电池》为例

Application of Problem-based “Four-step Method” in Chemistry Classroom of Senior High School Taking Primary Battery as an Example

以问题为主线,“创设情境问题、协作研究问题、总结归纳问题、巩固内化问题”的“四步法”教学,是教师积极引导学生主动学习的教学理念,可提高学生对化学学科知识探索的积极性,不断提升其学科素养,进而提升高中化学课堂效果。本文在分析高中化学课堂存在的问题基础上,阐述“四步法”的内涵及意义,并通过高中化学必修二《原电池》案例,分析“四步法”的应用效果。

The“four-step”teaching method of“creating situational problems,collaborative research problems,summing up and summarizing problems,consolidating internalization problems”is a teaching concept with a student-oriented and teacher-led teaching idea,which can stimulate students'interest in chemistry knowledge,continuously improve their subject accomplishment,and further improve the effect of chemistry classroom in senior high school.Based on the analysis of the existing problems in high school chemistry classroom,this paper expounds the connotation and significance of“four-step method”,and through the case of“primary battery”which is compulsory two in the high school chemistry book,analyses the application effect of“four-step method”.
