Research On The Teaching Design Of Trigonometric Function In High School Based On The Core Literacy Of Mathematics

The core literacy of mathematics is the key to the implementation of quality education.The quality of teaching design directly affects the effect of classroom teaching.The research and analysis of the high school trigonometric function teaching design based on the core literacy of mathematics is mainly to provide front-line teachers with a teaching design plan for cultivating the core literacy of mathematics of students and improve the efficiency of classroom teaching.This article uses literature research methods,questionnaire survey methods,interview methods,case analysis methods,classroom observation methods,etc.to study the teaching of trigonometric functions in high school.On the one hand,this study focuses on how to improve the teaching effect of trigonometric function based on the core literacy of mathematics in class.On the other hand,we should construct the teaching design model based on trigonometric function and carry out the cultivation of mathematics core literacy in mathematics classroom teaching.First of all,in this article,the method of questionnaire survey and interview is used to investigate and research the current situation of trigonometric function teaching in high school,and analyze the shortcomings of both teachers and students in the teaching process.The survey results show that most teachers still use traditional teaching methods and do not seek to design teaching centered on cultivating students' core literacy in mathematics.However,the students' mathematics core literacy is low,the enthusiasm of learning trigonometric function is not high,students are not good at making problems,intuitive imagination,mathematical abstraction,logical reasoning and mathematical modeling ability.Secondly,according to the system theory,learning theory and teaching theory,this paper puts forward six basic principles to improve the teaching design of trigonometric function in senior high school : Internalize mathematics core literacy,define teaching objectives,think about mathematics core literacy,formulate teaching difficulties,cultivate mathematics core literacy,infiltrate correct teaching methods,implement mathematics core literacy and design teaching process;integrate mathematical culture and humanistic atmosphere to design and activate teaching content;Combined with the core literacy of subject mathematics,focus on teaching evaluation.At the same time,it gives five basic strategies of trigonometric function teaching design in senior high school: highlight the leading position of learners and learn to question and criticize;create teaching situations to promote inquiry learning;design problem guidance to promote students' in-depth inquiry;build a cooperation platform to cultivate the spirit of cooperation;design effective homework and move students' thinking.In view of the above teaching suggestions,the teaching design examples and analysis of three trigonometric function contents are given as a teaching reference.Finally,after the end of teaching,the students were investigated and analyzed by questionnaire,and it was found that the level of students' mathematical core literacy was improved,their enthusiasm in learning mathematics was high,and their academic performance was ideal.the ability of intuitive imagination,mathematical abstraction,logical reasoning and mathematical modeling has been improved.In addition,this paper also interviewed teachers and collected suggestions to improve the research conclusions,and looked forward to the next step of work.
