The Exploration And Practice Of Micro-lesson Of Teaching "Required Module 1" In Senior Middle School

Since the beginning of the Micro course applicated in physics teaching in 2010,More and More educators are beginning the study of micro-lessons.However,the practice and the development of physics micro-course arestill relatively weak.The theoretical development and the study practice of micro-lessons are out of touch in physical discipline.The purpose of this study is aimed at exploring the effective methods of micro-lessons used in physics teaching.The study's objects are the leading role of students and teachers.It's also aimed to find the definite principles of the physics micro-lessons of by questionnaire,interview and so on.Through the different classes in different teaching programs on the same teaching content of the teaching mode and classroom timing training results of the data analysis,to explore the concept of micro-class,regular micro-class,exercise-type micro-class and other different types of micro-courses It also involves where we should use Micro course and how to use Micro course more wisely.It's showed that The needest of students are difficult and key points(including concepts,principles and exercises).The contents is same with what most teachers choose when designing micro-lessons content.There is no need to make there is no need to make a Micro course for the easy concepts,principles and exercise.Because It's difficult to arouse students' enthusiasm of learning,and it's no meaningful.The different difficulty and different types of micro-lessons hould be practised in different learning links.It's better to use simple conceptual and regular micro-lessons as preview before class.It's better to use the relatively difficult contents as the preview and reusing as consolidation in class.It's better to use exercise micro-lessons as preview than in the class as explaining.All of the micro-lessons are not suitable for works of after class,especially for simple content.The order of contenes for class should be adjusted accordingly.Considering the spending of time and learning efficiency,the best choice is using before and in class.Although it's effective to use micro-lessons to deal with some difficult contenes such as Newton's Second Law,and it will cost so much more time.The objects of this study are the medium-level students whose physical basis is medium levelThe subjects of the study are teachers coming experimental classes of Shuangliu School.It's easily copied and spread for other.And they can easily become practical materials of micro-lessons which are aimed to provide some reference for teachers.
