Research On The Current Situation And Cultivation Of High School Students' Ability To Combine Numbers And Shapes

As a research method to guide the process of physics teaching and learning,the"number" in physics is the data of physical quantity.The "shape" in physics can refer to the graph of physical process and the image of functional relationship between physical quantity.By transforming and unifying the "number" and "shape",students can understand the essence of physical problems More thorough,to achieve the transfer of knowledge and methods.It can be seen that the development of high school students'ability to combine numbers and shapes is of great significance to the development of students in all aspects.However,through the review of the previous literature,we can find that although many researches have realized the guiding significance of the idea of the combination of numbers and shapes for the physical system,in the specific research process,they only stay at the stage of using the combination of numbers and shapes as a physical problem-solving tool.There are few articles on the mastery level and ability of students'using the combination of numbers and shapes to solve problems,and there is no multi-directional Multi level mining as a research method how to penetrate into the high school physics teaching process.Based on this,this paper hopes to find out the current situation of high school students' ability of combining numbers and shapes through investigation and research,so that students can better understand their level of solving problems by using the idea of combining numbers and shapes,and pay more attention to the application of the idea of combining numbers and shapes in solving problems in later learning.At the same time,on the basis of the results of the investigation,the paper puts forward the improvement strategy of improving the high school students' ability of the combination of number and shape in physics teaching.Through the mutual correspondence of "shape" and "number",the students can deepen their understanding of the problem through multi-level and all-round observation and thinking.The main work of this study is as follows:(1)The compilation of the questionnaire of the cognitive state of the high school students' thinking method of the combination of number and shape.The purpose of this study is to investigate the students' understanding,access and attitude towards logarithmic combination.(2)Senior high school students' ability to solve physical problems by using the method of combination of number and shape.(3)This paper analyzes the current situation of the ability of number shape combination in senior high school students' physics learning,and puts forward some strategies to improve the ability.(4)The effectiveness of the strategy is tested by comparing experiments.The conclusions of this paper are as follows:(1)The thinking method of logarithm combination of senior high school students is simple and narrow in scope.Most students' understanding is only a kind of problem-solving tool,and only a few students think that this method can help to understand physical knowledge.(2)Students have a good attitude towards using the method of combination of numbers and shapes to study physics,showing a positive attitude;the ideological method of combination of numbers and shapes has also attracted the attention of teachers.(3)The ability of number form combination of high school students is generally low.Only 3.39%of the students have reached the higher level 3.(4)Compared with "figure formation",senior high school students are easier to solve the problem of "figure formation".It is more difficult for students to face the transformation from "number" to "shape".(5)This paper puts forward the teaching strategy of "stimulating students' interest by creating the situation of combination of numbers and shapes-assisting in teaching by using the idea of combination of numbers and shapes-internalizing the idea of combination of numbers and shapes through practical application",which can effectively improve the ability of combination of numbers and shapes of senior high school students.
