Research Of Teaching Strategies Of Electrical Experiments In Middle School Physics

Physics is a natural science based on experiments.The establishment of physical concepts and the discovery of physical laws are based on strict experimental facts.Physics experiments have an important status and role in physics teaching.Middle school electricity experiment is an essential approach for middle school students to access electricity knowledge.It is also an important basis,content and means for middle school physics teachers to carry out electricity teaching.Electricity experiment is a crucial component of middle school physics studies and a key point for middle school academic examination experiment questions.Moreover,the electricity experiment in middle school physics courses can stimulate students' interest in electricity concepts and applications.It creates a learning environment for students to master electricity knowledge effectively,and cultivate students' ability of electricity experiment and scientific literacy.Based on the investigation and the analysis of the current teaching situation,and the problems and causes of electrical experiments in middle school physics class,this thesis triggered physics teachers in middle school to consider the teaching of electricity experiments:how to carry out effective teaching of electricity experiments to exercise students' hands-on skills and assist them in making a breakthrough in their thinking barriers.Let students cultivate excellent quality and experimental electrical ability through experiments:independent thinking,questioning ability,respect for facts and the courage to innovate.This thesis consists of four chapters,the main contents of which are as follows.Chapter 1 is the preface.It mainly discusses the necessity of exploring the experimental teaching strategies of middle school physics electricity from the background,the idea,the content,and the significance of the study.Most of the current research on middle school electricity experimental teaching is conducted on the premise that the laboratory electricity equipment can meet the teaching needs.Facing the obsolescence and shortage of electrical equipment in school physics laboratories,weak foundation and poor learning habits of students,teachers need to explore strategies further to carry out experimental electrical teaching on making full use of the laboratory equipment available.Chapter 2 is a survey study on the current teaching status of electricity experiments in middle school physics studies.Through the questionnaire survey of teachers and students,the current teachers' teaching status and students' learning status of electricity experiments were observed.The problems in teaching electricity experiments and the causes were analyzed.It points out the direction for the exploration of teaching strategies.Chapter 3 is the teaching strategies and teaching practices of physics electricity experiments in middle school.The physics electricity experiments' teaching strategies are extracted through literature research and experience summary: developing low-cost experiments to exercise hands-on skills;conducting micro-experiments at home to extend classroom teaching;supplementing exploratory experiments to break through thinking barriers;promoting experimental learning with the help of simulation labs.The teaching strategy would be put into practice in specific electricity practical teaching to verify its effectiveness.Chapter 4 is the effect analysis and experience summary.A controlled experiment was used to statistically analyze the physics scores of the three exams of the midterm,final and the first mock examination of the midterm in the middle school to show a positive role of the electricity experiments' teaching strategies in middle school proposed in this paper.In addition,the shortcomings and future intentions in this study were described.
