A Case Study On Inquiry Experiment Teaching Of Mechanics In Senior Middle School

In order to implement the new curriculum goal of physics education in senior high school,and promote students' all-round development,students' physical science literacy must be improved.Among them,the cultivation of experimental inquiry ability is an important link in the cultivation of physical core literacy,which is mainly realized by making students master the method of experimental inquiry.Therefore,it is very important to improve the effect of inquiry experiment teaching.The exam-oriented education of college entrance examination and the difference of the difficulty degree of the physics knowledge system of senior high school lead to the lack of attention to the mechanics inquiry experiment in middle school to some extent.This paper studies how to effectively cultivate students' experimental ability and scientific inquiry ability in the process of mechanics inquiry experiment teaching,which takes the experiment of exploring the relationship among the acceleration and force,mass as an example.For carrying on the research to the topic,this article mainly uses the methods of literature research,the questionnaire survey,the interview and so on,and it has 6 chapters altogether.Chapter 1 is the introduction,and it mainly elaborates the background,the goal and the domestic present situation of this paper's contents,and based on these,the research content and the research method are determined.Chapter 2 is the theory summaries.In this chapter,the related concepts of experimental teaching are defined;the theory and practice of constructivism,cooperative learning and physics experimental teaching are briefly introduced.In chapter 3,the author investigates the present situation of mechanics inquiry experiment teaching in senior high school.And through a questionnaire survey and interviews with the first-year college students and the first-line teachers in middle school,the current teaching situation of mechanics inquiry experiment is understood and the problems existing in teaching are analyzed.In chapter 4,based on the investigation and literature research,five experimental teaching strategies are worked out by analyzing the experimental mechanics cases of mechanics inquiry in senior high school.There are life situation transformation strategy,traditional and modern experimental design strategy,experimental task-drive strategy,algorithm and image method combined data processing strategy,communication and reflection of the conclusion evaluation strategy.In chapter 5,based on the proposed teaching strategy of mechanics inquiry experiment,the teaching idea is determined,which takes the experiment of exploring the relationship between acceleration and force,mass as an example in this paper.Also,the teaching links are designed,and the preliminary teaching design of the mechanics inquiry experiment in senior high school is formed.On the other hand,through the implementation and evaluation of teaching,the teaching design is further optimized.In chapter 6,the research contents of the paper is summarized and the practical value of this research is pointed out,and this paper puts forward some reasonable suggestion for the design and implementation of the inquiry experiment teaching.Through questionnaire and interview,the author found that there is a difference between the teaching of mechanics inquiry experiment and the requirement of curriculum.So,combined with the analysis of the case of mechanics inquiry experiment teaching,this paper puts forward five teaching strategies to carry out mechanics inquiry experiment teaching.Based on the analysis of the results of the implementation,the conclusion is drawn: when five teaching strategies are adopted to conduct experimental teaching of mechanics inquiry,the students' main position is highlighted,which is not only beneficial to cultivate students' autonomous learning ability and cooperative learning ability,but to improve students' ability of independent design.And students have chance to go through the process of mechanics laws establishment,and the understanding of the general method of establishing physical laws is deepened,so the students' scientific inquiry ability and experimental ability are cultivated.The strategies and links of mechanics inquiry experiment teaching summarized in this paper have a good reference value for the high school physics teaching which carries out the cultivation of core quality.
