Study On Optimum Timing Of Redox Reaction Teaching Connection

The teaching of current middle school chemistry courses is mainly staged teaching,and the knowledge of redox reactions in secondary school textbooks appears in stages in junior high school,high school compulsory one,compulsory two and elective modules,resulting in students in different stages of redox reaction There are differences in learning.In order to avoid the adverse effects of faults in the teaching of each stage on students’learning efficiency,this paper studies the convergence and existing problems of different stages of redox reaction.Due to the new curriculum reform,the middle school chemistry class hours are now very tight in both junior high schools and high schools.How to connect these different stages of redox reaction knowledge efficiently requires appropriate teaching opportunities to achieve better results.Teaching effect.This study mainly reviews the current status of redox reactions and adopts research methods such as literature,interviews,and action research.According to the knowledge of redox reaction in different stages,several convergence points of redox reaction are summarized.Based on the theoretical analysis,a questionnaire was prepared to study the main problems of the students in the redox reaction learning of high school students,and the timing of the teaching of redox reaction teaching was found by combining the teaching points of redox reaction.To promote the teacher’s teaching in the redox reaction knowledge section and the student’s learning progress.
