Research On The Evaluation Of The Formation Of The Concept Of Work In High School Students Under The Development History Of Physics Concepts

In the teaching of basic physics,the concept of physics is regarded as the "cornerstone",and the teaching of the concept of physics has always been highly valued.Especially under the baton of developing students’ core literacy as the training goal,physics educators pay more attention to the importance of the teaching of physics concepts to the formation of physics concepts,and the level of students’ physical concept formation is closely related to the development of core literacy.At present,the research on the formation process of physical concepts has been scattered,but the research on the evaluation of the subject of "physical concept formation" is lacking after searching literature.Therefore,this study attempts to select the physical concept of Work based on the development history of the physical concept,and adopts research methods such as survey research methods to carry out the following three parts of research work:The first part: By consulting literature and books,referring to the relevant theoretical basis of physical concept formation,dividing the physical concept formation level into hierarchical levels,and describing its definition.After evaluation and discussion,the physics concepts from the horizontal frame table with "Three tiers and nine levels" was established.The second part: Based on the development history of the Work concept,excavate the historical process of the formation of the Work concept,and select and compile the situational materials to make them the materials that can be used to form the test paper situation with the Work concept.Then formulate a two-way breakdown table of the design of the test paper with the concept of Work,which is used as the benchmark for the design of the test questions,and the concept of Work is designed to form the test paper.After discussing with experts to make corrections,and using the SCE model to analyze the consistency of the Work concept formation test paper and the Work concept formation process materials in content topics and concept formation levels,the results show that there is an acceptable consistency.Finally,a Work concept that can be formally tested is formed to form a test paper.The third part: Taking 500 students from 4 high schools in Guangxi as the test samples,mainly using SPSS25 and Excel for statistical analysis,it is calculated that this test paper has a degree of discrimination and suitable difficulty in the statistical sense.And there is a significant correlation between each question and the total score of the test paper.From the evaluation of the formation level of high school students’ Work concept formation,we can get:(1)The average score of all the students tested is 72.87% of the full score of the test paper,and the average level of the concept of student work is good.The standard deviation of students’ performance is relatively large,which is 9.148,which indicates that students’ level of Work concept formation is uneven;Judging from the achievement ratio of each level of Work concept formation,almost all students can reach the level of "knowing",and the proportion of students with a high level of Work concept formation is less.Judging from the differences of different student groups,the level of Work concept formation of the third-grade students is generally higher than that of the second-grade students,and the formation level of the students’ Work concept is positively correlated with the physical performance to a certain extent.(2)According to the test situation,8 factors influence the formation of the concept of success,such as "improper understanding of the concept" and "Insufficient Modeling Ability",among which the data shows that the students are the most disturbed in the factor of "the concept of conservation is not strong".(3)After analysis,the formation and development history of the concept of Work contains the elements of the core literacy of the physical discipline.Judging from the physical core literacy assessed by the Work Concept Formation Test Paper,the development level of the students’ core literacy is relatively good.In addition,the questionnaire survey of students’ attitudes towards the test paper for the formation of the concept of Work reflects that most students have a positive attitude towards this test.
