Research On The Influence Of High School Mathematics Teachers' TPACK Level On Students' Trigonometric Function Learning Achievement

Today's information society advocates the integration of technological means into subject teaching,and every teacher faces this new challenge.Therefore,people pay more and more attention to the related theories of the technical teaching knowledge(Technological Pedagogical Content Knowledge,referred to as TPACK)that integrates technology.Among them,"whether teachers' TPACK level can affect students' academic performance" is one of the key contents of educators' research.One,but the research on this issue is still under discussion,and no generalizable research results have been obtained.Based on the investigation and analysis of the TPACK level of mathematics teachers and the results of the trigonometric function test results of high school students,this paper specifically discusses the relationship between the two,aiming to deeply explore the effect of mathematics teachers' TPACK level on the academic performance of high school students.influence.This study selects nine math teachers and 360 students in their teaching classes in three high schools in C city,J province as the research objects,and conducts a research on the influence of high school math teachers' TPACK level on students' trigonometry academic performance.First of all,based on the Schmidt questionnaire and the Ashampert questionnaire,the "Senior High School Mathematics Teachers TPACK Level Survey Questionnaire" was compiled,and the item analysis,reliability analysis and validity analysis of the questionnaire were carried out to ensure the test.The results are scientific and effective.And based on the teaching objectives and teaching content requirements of trigonometric functions related knowledge in the textbook People's Education A version of the first volume of compulsory high school mathematics and the "General High School Mathematics Curriculum Standard(2017Edition)",the "High School Students' Trigonometric Function Knowledge" has been compiled.Proficiency Survey Test Paper".The survey and test data were qualitatively analyzed using EXCEL and SPSS,and the Pearson correlation method in R language was used to analyze the correlation between the TPACK level of high school mathematics teachers and the students' trigonometric function academic performance.The main conclusions are as follows:(1)There are individual differences in the TPACK level of mathematics teachers.(2)There is a moderate positive correlation between the TPACK level of high school math teachers and students' trigonometry academic performance.(3)Teachers' CK,PK,TK,PCK,TCK,and TPK levels have positive correlations with different degrees of trigonometric function learning performance of high school students,and the correlation degree of TK level is the weakest.Finally,on the basis of investigation and testing,from the subjective and objective levels,some reasonable suggestions for improving the TPACK level of mathematics teachers are put forward.
