Investigation And Research On Space Geometry Teaching Of Senior High School Teachers From The Perspective Of TPACK

Education to keep up with the development of the information age,so teachers in addition to the need to have good knowledge of subject content knowledge and teaching,grasp the good capability of information technology has become a compulsory course of mathematics teachers.As we integrate more and more information technology into teaching,TPACK,the subject teaching knowledge of integrated technology,has become an important topic in mathematics teaching research.However,there are relatively few investigations and studies on specific teaching contents of a certain discipline,and geometry courses are the best carrier to cultivate students' mathematical abstraction and intuitive imagination accomplishment.Therefore,it is of great theoretical and practical significance to investigate and study the current situation of spatial geometry teaching of high school mathematics teachers from the perspective of TPACK.In this paper,based on the reading of a large amount of relevant literature,with deep TPACK theory,information technology and curriculum integration theory and scale measurement framework to support,for part of high school teachers' questionnaires and interviews,the teachers of different background variables in the space geometry teaching TPACK levels of the difference and correlation,after detailed analysis of the questionnaire,interview is representative of teachers to find background questionnaire response problems of reason,gives advice from all directions.Through the data analysis of the questionnaire and interviews,the following conclusions are drawn :(1)teachers' ability to use information technology to assist the teaching of solid geometry still needs to be strengthened;(2)the growth of teachers is inseparable from practice;(3)old teachers are not active in integrating information technology into teaching;(4)limited by their own experience,young teachers cannot maximize the role of integrated information technology teaching;(5)students influence teachers' teaching methods;(6)teachers' application of information technology is relatively simple.According to the conclusion and the interview,the following Suggestions are put forward :(1)straighten out the teachers' views on the introduction of information technology into the three-dimensional geometry classroom;(2)strengthen network communication and resource sharing among teachers;(3)for schools,they should develop reasonable information technology intervention methods based on their students' mathematical ability;(4)schools can enhance the communication effect between teachers and students through the construction of information technology infrastructure;(5)strengthen the communication between in-service teachers and trainee teachers;(6)teachers' education and training institutions should strengthen the education of information technology and its application.
