Research On The Application Of The Thought Method Of The Combination Of Number And Shape In The Teaching Of Physics Exercises In Senior One

The 2017 edition of the "General High School Physics Curriculum Standards" pointed out in the nature of the curriculum that high school physics aims to guide students to understand nature and understand nature from the perspective of physics,so that students can construct a physical picture of nature,and let students gradually learn in the process of learning.Cultivate scientific thinking habits,form a scientific attitude,scientific world view and correct values.High school physics has many features,and the physical process is abstract and complex,which causes difficulties for high school students to analyze and solve physics problems.The combination of numbers and shapes can solve this problem,and it can help abstract Visualize physical problems to clarify complex physical processes,thereby reducing the difficulty of problem understanding and promoting problem solving.At the same time,in the process of solving mathematical problems with the combination of mathematical and ideological methods,students can also cultivate the students' ability to construct a physical picture,promote the development of students' thinking ability,develop students' scientific way of thinking,and form a good scientific attitude.Therefore,it is very necessary to study how to train students to apply the combination of numbers and shapes in the teaching of exercises.This research mainly adopts literature method,text analysis method,investigation method and experiment method.Through the analysis of the exercises in the high school physics textbooks,understand the characteristics of the combination of numbers and shapes in the textbook exercises;with the help of a questionnaire,the current situation of 31 high school physics teachers applying the method of combining numbers and shapes in the teaching of physics problems Quiz questions,a total of 191 students in the first grades of 4 classes,using the combination of mathematics and thought to solve the problem of the status quo survey;on the basis of understanding the characteristics,current situation,analysis of reasons,how to strengthen the mathematics in the exercise Combined with the cultivation of ideological methods,the strategy was discussed,and the experimental teaching plan was designed.Through the comparative teaching of the two classes,the effectiveness of the cultivation strategy was discussed.Research shows:1.High school physics teachers need to pay more attention to the combination of numbers and shapes,which is mainly reflected in the lack of attention to students' application of the combination of numbers and shapes,the lack of active discussion on the teaching strategy of the application of the combination of numbers and shapes in teaching,and the understanding of the combination of numbers and shapes.2.The students' consciousness of solving physical problems by using the method of combination of number and shape is not strong,which is mainly reflected in neglecting the importance of graphics when analyzing problems,failing to form a good habit of drawing when solving problems,and inclining to apply formulas to solve physical problems.3.The students' ability to solve physical problems with the combination of numbers and shapes is not strong.They lack the ability to decompose complex images and associate new images when solving the problem of "solving numbers by shapes";they lack the ability to compose pictures when solving the problem of "digitizing shapes";they lack the ability to transform between pictures when solving the problem of "mutual aid of numbers and shapes".4.Based on the investigation and analysis of the current situation of applying the combination of mathematics and form in high school physics teaching,this paper proposes a strategy for cultivating students to apply the combination of mathematics and form in thinking through high school physics exercises.The implementation plan of this strategy was explored and teaching practice was carried out.The practice found that the strategy of cultivating students to apply numbers and shapes in combination with thoughts and methods in the teaching of physics exercises in senior high schools is obvious for the cultivation of students' ability to "solve numbers by shape" and "form by number" The effect has certain promotion effect on the development of students' ability of mutual aid in number and form.
