A Case Study Of Junior Middle School Physics Teaching Design Based On Micro Lesson

Under the background of educational informatization,micro-class is widely used in classroom teaching for its short,concise and targeted features,which solves many teaching difficulties.According to the characteristics of junior high school physics class under the new teaching mode,this paper expands the application scope of micro-class,analyzes the function of micro-class in physics teaching from the aspects of micro-class selection and application,and obtains a complete application process of micro-class teaching,which provides a reference case for teachers to adopt microclass teaching.This paper is mainly divided into the following parts:First,through the literature research method to understand the structure,characteristics and research situation at home and abroad of micro-class and other related content Second,through the questionnaire survey method to carry on the preliminary iirvestigation,obtains the present junior high school physics classroom teaching pattern the characteristic mainly by the group cooperation study and the guidance case,and carries on the analysis to the micro class in the classroom use situation,cames on the summary to the present stage micro class teaching existence question.Three,Studying the junior middle school physics textbooks and curriculum standards,reclassifying the junior middle school physics micro-lessons according to the textbook columns,the role of micro-lessons,the students'problems in learning physics and other factors,and expanding the scope of micro-lessons.Fourth,according to the junior high school physics classroom teaching pattern,obtains the micro lesson teaching design principle and the application process.Five,according to the micro-lesson teaching design process,select the appropriate curriculum to design a micro-lesson teaching case,and through case implementation,evaluation and feedback analysis,prove that the well-structured high.quality micro-lesson in the case plays a role in preview before class.extended learming after class,achievement of teaching objectives,breakthrough of teaching difficulties and interests of students,so as to prove the feasibility of the case.Finally,according to the practical process,the paper summarizes some suggestions on the application of micro-class in physics classroom teaching,and puts forward the prospect of the development direction of micro-class in the future teaching.
