Teaching Strategies And Case Design Of Physics Electrical Experiments In Middle School

Electricity is the key and difficult point throughout the physics course in junior middle school,as well as one of the major examination points of the senior high school entrance examination.Experiment is the soul of physics and experimental teaching method plays an important role in physics teaching in middle school.Physical experiment can improve students' interest in learning physics,promote their further understanding of the concepts and principles of physics,enable them to better grasp the basic theories of physics,and develop their practical abilities and basic skills for conducting scientific experiments.Besides,it enables students to learn the scientific methods of exploring unknown things,which not only develops students' observation ability,thinking ability and practical operation ability but also cultivates students' scientific literacy,innovative spirit and innovative ability.This paper firstly introduces the background of the research of electrical experiment teaching,analyzes the present research situation of the subject at home and abroad,and explains the purpose and significance of the research and so on.Based on this,some related theories of electrical experiment teaching are introduced to claim some basic strategies of electrical experiment teaching.Secondly,a questionnaire survey of 150 students and 35 first-line teachers has been conducted on the electrical experiment teaching of physics in middle school,and two of them have been invited to an interview.This has led to the further investigation and analysis of the status quo of teaching and the status quo of students' learning in junior middle schools.Next,according to the setting content,teaching objectives,and teaching strategies of electricity experiment courses in junior middle school,regarding electricity experiment teaching in junior middle school and the status quo of students' learning,such three sections as Measurement of Current,Rheostat and Measurement of Resistance have applied teaching design to practice,analyzing its teaching effects and summing it up.Finally,I have drawn a conclusion to the research of this subject and also reflected its disadvantages.I'm expecting to further discuss questions about electricity experiment teaching in junior middle school in the future.
