A Case Study On The Application Of Self-made Teaching Aids In The Teaching Of Physics Problem Solving In Senior High School

As an important teaching resource in experimental teaching,self-made teaching aids play an important role in middle school physics teaching.Problem solving teaching is an important teaching method in senior high school physics teaching.In recent years,with the proposal of core physical literacy and the introduction of the general senior high school physics curriculum standard(2017 Edition),more and more researchers pay attention to how to cultivate students' ability of solving physical problems.Since the self-made teaching aids can play its unique educational function in physics teaching,what kind of teaching effect will be produced if they are applied to the teaching of physics problem solving in senior high school?The author chooses a school in this region that often develops and makes self-made teaching aids by using all kinds of things in life and builds a regional demonstrative physics "subject classroom" as a case study,hoping to find out how to apply self-made teaching aids in the teaching of physics problem solving in senior high school and how to use such teaching methods through the analysis of the teaching behavior of the teacher Whether it is valid.This paper is divided into two parts.In the first part,the author mainly studies how to use self-made teaching aids in the teaching of physics problem solving in senior high school.First of all,the author investigated and analyzed the work of the teacher in the use of self-made teaching aids through interview and observation;secondly,the author observed and analyzed the teacher's teaching behavior through observation.On this basis,the author draws the following conclusions:Before class: teachers can find the inspiration of self-made teaching aids through the physical picture given in the textbook and exercise book exercises;teachers should have a very clear understanding of self-made teaching aids and the problems to be solved and the physical picture described.Class: in class,when using self-made teaching aids for demonstration experiment,we should make the problem prominent and the phenomenon obvious;in the process of solving the problem,we should highlight the idea of model construction,and combine the observation phenomenon with the theoretical analysis;we can use self-made teaching aids to create the problem situation,and we can also use self-made teaching aids to test the theoretical analysis.After class: leave open questions appropriately;encourage students to find problems by themselves from the phenomenon of self-made teaching aids,and solve problems in various ways.In the second part,the author studies whether the teacher's teaching method is effective.The author investigated the teacher's teaching by observing the students' performance in class,interviewing after class and collecting the students' completion of homework,and came to the following conclusion: the use of self-made teaching aids for physical problem-solving teaching is helpful to the students' enthusiasm for solving physical problems,model construction ability and problem-solving ability.
