Study On The Influence Of High School Mathematics Teachers' Subject Teaching Knowledge On Classroom Teaching

With the continuous progress of society,our country has set a higher goal for the development of education.In more than ten years of curriculum reform,our requirements for teachers' professional ability are constantly upgrading,and the requirements for classroom teaching quality are constantly improving.In this context,teachers' subject teaching knowledge gradually began to be concerned by many educators,become an important part of teachers' professional development,and play an indispensable role in teachers' classroom teaching.However,some teachers still pay less attention to the subject teaching knowledge and the professional ability is not prominent,which hinders the development of curriculum reform.This paper mainly studies mathematics teachers in classroom teaching reflected differences in subject teaching knowledge,and the impact of these differences on classroom teaching.It is hoped that more teachers will pay more attention to the subject teaching knowledge and give some suggestions for teachers to improve the subject teaching knowledge and improve the classroom teaching quality.Based on the division of subject teaching knowledge by Grossman in 2005,this paper discusses the influence of high school mathematics teachers' subject teaching knowledge on classroom teaching from two aspects: teachers and students.In terms of teachers: select the second chapter "equality and inequality" of the 2019 new edition of teaching materials for human education B as a specific topic,through classroom observation,interview,case analysis to investigate the difference between the two representative teachers in subject teaching knowledge.In terms of students: through questionnaire survey,classroom observation of students and students' test results to obtain data,using Excel and IBM SPSS Statistics 23 to analyze the collected data,it is found that teachers' subject teaching knowledge will have a significant impact on classroom teaching.The results show that teachers can effectively improve the quality of classroom teaching by using their own subject teaching knowledge reasonably.Teachers' understanding of curriculum standards and teaching materials and their mastery of subject knowledge will affect the depth and breadth of teaching;teachers can organize teaching on the basis of students' understanding and set reasonable teaching objectives,which is more conducive to the development of classroom;timely feedback of students' learning situation,the adoption ofa variety of teaching strategies can effectively enhance students' interest in learning and learning motivation,but also improve the quality of classroom teaching.In order to improve the quality of classroom teaching,it is suggested that high school mathematics teachers should improve their teaching knowledge through the following ways :(1)deepening the research on teaching materials and curriculum standards;(2)deeply understanding students;(3)paying attention to cultivating students' interest in learning;(4)diligent in reflecting and summing up their own teaching;(5)constantly learning and increasing their knowledge.
