Implement The Research On The Abstract Literacy Of Mathematics In The Teaching Of Trigonometric Functions In High School

The revised version of mathematics curriculum standard for senior high schools requires that student development be the basis,the fundamental task of cultivating people and improving the core quality of mathematics in learning" be the aim of the curriculum.It clarifies six aspects of the core quality of senior high school mathematics: mathematical abstraction,logical reasoning,mathematical modeling,visual imagination,mathematical operation and data analysis,while mathematical abstraction is the sixth.First of all,it is not only the basic thought of mathematics,but also the important foundation of forming rational thinking.It is the foundation of forming and developing mathematics discipline.It reflects the essential characteristics of mathematics and runs through the whole process of producing,developing and applying mathematics.Therefore,this paper combines the realization of cultivating students mathematical abstract literacy in trigonometric function teaching based on the theory of mathematical abstract literacy to carry out specific research.Firstly,this paper uses the method of literature review to explain the relevant concepts involved in the article reasonably;secondly,it uses classroom observation and interview to make a questionnaire survey to senior high school teachers in view of the current situation of senior high school mathematics teaching,expecting to analyze the problems existing in schools,teachers and other aspects in the implementation stage of mathematical abstract literacy through the results of the questionnaire;lastly,it adopts the action research method.Combining with the theory of mathematical abstract literacy,this paper puts forward the method of implementing mathematical abstract literacy in the teaching of trigonometric function in senior high school according to the type of mathematics course(new lecture,exercise class,review class).Based on the survey results,teachers pay too much attention to calculation and results in the teaching of trigonometric functions under the influence of college entrance examination orientation and self-quality.they ignore the cultivation of students abstract mathematical literacy in the teaching of concepts and processes,sothat students’ understanding and mastery of trigonometric functions remain in the shallow application of common and Mechanical operations.This paper studies the implementation of mathematical abstract literacy in trigonometric function teaching according to different types of courses,aiming to provide a reference scheme for front-line teachers.In specific teaching,teaching methods should be selected comprehensively according to the actual teaching environment and different sources of students.There are still some shortcomings in this study.It will take a long time to verify the implementation of mathematical abstract literacy.
