Research On Application Of Micro-lesson To The Preview Of Math Class In Grade One In Junior High School

With the era of “micro” coming,products like MicroBlog,WeChat,micro-video and micro-film are having an impact on people's life and study.Micro-lesson,as the time product of the combination of education and information technology,has become an important medium and resource of personalized and autonomous learning.At present,there are some problems that need to be solved urgently in students' preview of math classes in Grade Seven,such as students' superficial understanding,monotonous forms and low efficiency.How to improve the effectiveness of the preview of math classes? Using micro-lesson to aid students' preview of math classes may be an effective way to solve these problems.Under instructions of theories and based on realistic requirements,this research,targeted at students from two classes in Grade Seven in a demonstrative middle school,explores the application of micro-lesson to the preview of math classes in Grade Seven by means of summarizing experience,theory speculation and experimental researches.Specifically speaking,this research mainly focuses on the following contents.One aspect is the theory.After reading a great number of literatures,the author makes a summary of current researches at home and abroad,concepts,characteristics and teaching theories of micro-lesson;By means of theory speculation and summarizing experience,it explores functions and application strategies of micro-lesson in the preview of math classes in Grade Seven.The other aspect is practical research.Mainly focused on teaching practice as well as investigation and interview,this research explores whether the application of micro-lesson to the preview of math classes is valid for students' academic performance and learning process.This research suggests:1.Using micro-lesson to aid students' preview of math classes in Grade Seven can greatly improve students' math grades in Grade Seven.2.Using micro-lesson to aid students' preview of math classes in Grade Seven can,to some extent,arouse students' interest in learning math,promote students' understanding of math and improve students' learning method of math.
