Conduct Research On Layered Teaching In The Comprehensive Practical Activities Of Junior High School Physics

Based on curriculum standards, The Physics Teaching aims to improve the students' scientific literacy and pays attention to comprehensive practice activities.More and more schools have carried out the comprehensive practical activities.However, up to 53% of the schools carry out less than 20% of the practice themes. In this background, the author combines the schools together whose students have weakness of basic knowledge. After carefully investigating the source of students, the author divides the students into A, B and C level to set up groups with different intelligence and abilities according to the students' mathematical basis and the observation in class. The author has carried out 13 themes in the comprehensive practical activities in a year by adopting covertly stratified interactive teaching approach. The article shows the teaching practice of the author through concrete teaching cases. The study indicates that carrying out layered teaching has a good advantage in developing students' interest, lifting students' abilities of different levels and cultivating their qualities.
