A Case Study On The Teaching Of Mathematics Exercises In Senior High School

As an important part of mathematics teaching in senior high school,exercise class plays a very important role in cultivating students' ability to solve problems and improve teaching quality.As for mathematics teachers,a good day exercise class,teachers need to make adequate preparations,according to the students' cognitive structure,develop rigorous teaching plan,help students sort out the knowledge,through exercises to explain to promote systematic knowledge of students.Therefore,how to promote the teaching of mathematics exercises in high school is more and more effective in our country.Based on the above considerations,this article uses the literature analysis method and case study method,classroom observation method,combined with the author himself in the Shanxi province Linfen twelfth middle school internship experience,the author and the 56 high school classes all students as the research object,the use of nearly five months of internship time substitute,into high a math class,do a good lesson on how to exercise the high school mathematics novice teachers case study in the process of teaching practice in class exercises.This study focuses on the following three questions:(1)to find out the problems of students' learning difficulties in the course of "compulsory";(2)to solve the above problems,we can find a breakthrough method,so as to improve students' mathematics achievement.Through the study of high school mathematics exercises before class preparation,class teaching and teaching evaluation and reflection of teaching activities,further analysis,thus a more comprehensive understanding of high school mathematics exercises course teaching problems and get the following conclusions through the research:(1)it is difficult for students to solve the three problems of "obligatory function","Monotonicity and parity of function","exponential function and its properties","logarithm function and its application";(2)before class knowledge combing and learning situation prediction could effectively understand the status of students,and to carry out selected exercises;(3)class through the combined training way to guide students to think actively,cultivate students' mathematical thinking about how to communicate with students,understand students' thinking,found the problem solving obstacles,guide students to find methods to break through practice;when students give enough thinking space for exercise errors so as to improve the practice.The students' problem solving efficiency and the efficiency of classroom teaching;(4)correct and revise the homework after class,find out and analyze the cause of the mistake,and give enough attention to the students who have difficulties in learning,so as to improve the students' mathematics achievement.
