Optimization Strategy And Practice Of Grouped Experiment Teaching In Junior Middle School Physics

Physics experiment is an important form and method of physics teaching.The student group experiment is the core of the physics experiment,which plays an important role in improving the students' physical discipline accomplishment,and is an important link for students to acquire knowledge,develop ability and cultivate scientific spirit.Through interviews and questionnaires with teachers and students in several junior middle schools in chengdu,this paper aims to understand the current situation of physics experiment teaching in junior middle schools and try to seek scientific teaching methods,so as to better cultivate students' comprehensive quality and innovative ability in the teaching process.This paper is divided into six parts:The first and second parts mainly explain the background and research significance of the problem,and introduce the research direction,content and method by referring to the literature.The third part defines the relevant concepts,mainly focusing on the two concepts of physics experiment and group experiment teaching,and specifically expounds their connotation and extension,as well as their role and significance in the whole physics teaching.The fourth part investigates the present situation of physical experiment teaching and group experiment teaching in 5 junior high schools in chengdu city by means of interview and questionnaire.The existing problems include insufficient hardware facilities,insufficient attention,single teaching methods,and limited evaluation methods,which to some extent restrict the overall development of students and the formation of scientific literacy,so it is urgent to optimize experimental teaching methods.The fifth part,the investigation and listen to some of the first-line teachers on the basis of the opinions,the author attempts to put forward some optimization grouping experiment teaching strategy,including the teachers must set up scientific teaching concept,outstanding student's main body status,reasonable use of network technology to develop experimental resources,reforming evaluation system,etc.,according to the effective teaching strategy proposed in this paper,the author inteaching in the two classes of a semester optimization grouping experiment teaching practice,through experimental classes and that in comparative classes students self-evaluation and two large test results contrast,preliminary optimization strategy is verified in attracting students' interest,stimulating learning motivation,improve the physical performance of the role of,It shows that the optimization strategy has certain representativeness and operability.In the sixth part,the author summarizes the achievements of this research,reflects on the shortcomings,and makes a prospect for the future work.
