A Study On The Teaching Strategy Of Senior Ⅲ Triangle Function Review

"The High School Mathematics Curriculum Standards(2017 Edition)" puts forward that "high school mathematics teaching should be based on the development of students' core mathematics literacy,create appropriate teaching situations,inspire students to think,and guide students to grasp the essence of mathematical content" Resonance of the majority of educators,how to implement the "development of the core literacy of mathematics discipline" and "guide students to grasp the essence of mathematics content" in the mathematics review teaching in the third year has become a realistic problem.As a part of the traditional knowledge of high school mathematics,trigonometric functions occupy a very important position in both the mathematical knowledge system and the college entrance examination.What effective teaching strategies are adopted in the senior 3 high school review stage has always been the focus of the majority of frontline teachers.This paper takes M middle school in Li County,Gansu province as an example.Through the questionnaire survey method,interview method and test method,the research on the status quo and influencing factors of the review and teaching of the high-three trigonometric function is studied,and the students in the review stage of the trigonometric function are known.The review interest is not high,the knowledge cognition is not clear enough,the review method is time-consuming and inefficient,the review habit is poor,the review effect is poor,the teacher's review is one-sided,the review preparation is not enough,the review method is outdated,and the review feedback is not thorough enough..The main factors that affect the review effect of students are: subjective factors of students,choice of learning methods,teaching methods of teachers,etc.The main factors influencing teachers' review teaching are:cognition of review,understanding of academic situation,and Graduation of class and capacity,knowledge of self-cultivation,etc.Combined with the investigation of the current situation of teaching and learning of trigonometric functions and the analysis of influencing factors,this paper separately from psychological counseling,improve students' review initiative;pay attention toreview preparation,improve review targeting;optimize teaching methods,improve student review effectiveness;patience Four aspects,such as guiding supervision and cultivating students' good study habits,provide suggestions for teachers in the teaching strategy of the high-level trigonometric review stage.
