Research On The Construction And Application Of The Precise Teaching Model Of Enabling E-schoolbag

Mathematics review class is one of the important classes in junior middle school mathematics classroom teaching.Under the background of new technology driving educational reform,the assignment of electronic schoolbag can provide a new perspective and a new method to explore the accurate teaching of junior middle school mathematics review class.Precision teaching is a new teaching mode endowed with information technology.Researchers at home and abroad have applied the precision teaching mode to verify the effectiveness of precision teaching of junior middle school mathematics in improving academic performance.However,no empirical study has been conducted on the effectiveness of precise teaching of mathematics review lessons in primary and secondary schools with electronic backpacks.Therefore,how to innovate the precise teaching mode endowed by electronic schoolbag and verify the effectiveness of applying this mode in junior middle school mathematics review class is one of the important topics of this study.This study examined the prior literature,analysis and the research status of precise teaching and mathematics teaching mode at home and abroad,This research is based on the ability of e-schoolbag to construct the precise teaching mode of mathematics review lessons in junior middle school.It expands the number of segments in the precise teaching from "three" to "seven",including precise goal,precise grouping,precise understanding,precise research,precise evaluation,precise reflection and precise expansion.Then,it adopts the precise experimental research method in junior middle school.Teaching experiment is carried out in the review lessons of factorization.The experimental results show that the model cansignificantly improve students' mathematics learning performance,increase the proportion of "excellent students" in the class,reduce the proportion of "poor students" in the class,promote students' deeper learning in the cognitive field,stimulate learning initiative and autonomy,and cultivate positive math academic mood.The study also finds that there are five necessary conditions and three effective strategies for the effective implementation of the precise teaching of mathematics review in junior high school.This study explores the difference between the precise teaching mode of junior high school mathematics review lesson endowed with electronic schoolbag and the traditional teaching mode of junior high school mathematics review lesson,which enriches the research on the precise teaching theory of electronic schoolbag and provides the practical basis for the precise teaching mode of junior high school mathematics review lesson endowed with electronic schoolbag.
