Research On The Teaching Of High School Mathematics Chapter Initiatory Lesson Based On Micro-lesson

Chapter initiatory lesson is the "advance organizer" of each chapter with unique teaching value,which can help students establish a good cognitive structure and lay a solid foundation for subsequent learning.However,the educational function of the chapter initiatory lesson cannot be effectively played in the actual teaching.With the development of the times and the progress of educational information technology,"micro-lesson" has become an important educational technology in the field of basic education informatization.Therefore,this paper studies the teaching mode of the chapter initiatory lesson of high school mathematics based on micro-lesson.This paper includes the following parts.First of all,sort out the relevant literature of chapter initiatory lesson and micro-lesson,analyze the research status of chapter initiatory lesson and microlesson,and define the core concepts and related theoretical basis.Secondly,investigate the current situation of teaching implementation of the chapter initiatory lesson of high school by questionnaire survey.Then taking the chapter initiatory lessons of the two chapters of "Concepts and properties of functions"and "Exponential functions and the logarithmic functions" in Compulsory one of the People’s Education Press edition A textbook as an example,carry out micro-lesson productions and teaching designs.Finally,the teaching effect is tested through teaching practice and questionnaire survey.In the end,the following conclusion is drawn.Firstly,chapter initiatory lesson has rich teaching value,but it has not been effectively played in the actual teaching.Secondly,using the micro-lesson to auxiliary chapter initiatory lesson teaching has been recognized by most teachers,but due to the difficulties in micro-lesson production and other reasons,the teaching practice is less.Finally,the teaching mode of chapter initiatory lesson based on micro-lesson can give play to the teaching function of chapter initiatory lesson leading the whole chapter,improve the efficiency of classroom teaching,and have a certain role in promoting both teachers’ teaching and students’ learning.
