Research On The Teaching Practice Of Trigonometric Function In High School

With the development of education reform,the status of students as the main body has been strengthened,and inquiry learning has quietly risen.Although students have learned some special triangular function values in junior middle school,they still encounter many difficulties in the study of triangular function,such as understanding the concept of triangular function,memorizing the formula of triangular function,image transformation of triangular function,etc.But the foundation of mountain students is not good.When they enter high school,they feel inadaptable to the learning of function.The frustration of trigonometric function can easily make some students lose confidence in mathematics learning.How to improve teaching methods in daily teaching to help these students master triangular function more smoothly is a problem that teachers should think about,and also the starting point to carry out the research of triangular function inquiry teaching practice in this paper.This article is divided into five parts.The first part mainly elaborates the background of the research,the research question,the research ideas,research methods and the goal and significance of the research.The second part is about the definition of related concepts and literature review.The definition of related concepts includes the theoretical basis of inquiry,inquiry-based teaching,inquiry-based teaching of mathematics and inquiry-based teaching psychology.The literature review mainly describes the current research status of triangular functions at home and abroad.The third part is the feasibility survey of inquiry teaching,through the preparation of teachers and students questionnaire survey,to further understand the classroom basis of inquiry teaching.The fourth part is the study of teaching practice.The control class mainly refers to Kunihiko Kodaira's content structure of Mathematics I,and designs two teaching designs of Trigonometric Function Image and Trigonometric Function Nature in combination with the teaching material of Edition A of People's Education,and carries on the traditional teaching practice.The experimental class creates the situation based on the relationship between wheel and odometer,carries on the inquiry teaching practice,and finally conducts the research.Theprocess of practice was evaluated and analyzed,and a questionnaire survey was conducted in the experimental class.The fifth part is the summary of this paper.According to the questionnaire survey and teaching practice,it gives teachers suggestions and points out the shortcomings and prospects of the paper.
