A Study On The Effective Teaching Of Mathematics Based On Mathematics Key Competencies In Junior High School Grade Three Review Class

With the continuous development of world economy and education reform,the educational goal and teaching concept of mathematics subject have changed correspondingly.As the third stage of basic education in China,junior middle school is the key closing stage of basic education,and it is also an important education stage connecting primary school with high school and vocational secondary school.Mathematics,as one of the important basic subjects in junior middle school,plays an important role in junior middle school teaching.The mathematics review course of junior three is the main type of mathematics teaching in junior three,bearing the task of improving students' knowledge system and improving students' thinking quality,so as to meet the requirements of the high school entrance examination on the core quality of mathematics.Therefore,under the background of mathematics core accomplishment,it is of great practical significance to carry out effective teaching of mathematics in junior three with recitation class as the main class.First of all,through listening to 8 teachers' recitation lessons,interviewing 8 teachers and 60 students,and questionnaire survey of 265 students,this paper studies the current situation and causes of mathematics recitation teaching in junior three,and finds out its prerequisites and deficiencies in cultivating students' core qualities in mathematics.Then,according to the survey results,combined with the relevant theories of mathematics core accomplishment and effective teaching,this paper puts forward the basic principles and teaching strategies of effective teaching based on the mathematics review lesson of junior three.Finally,by combining theory with practice,this paper studies two typical cases of the teaching practice of junior three mathematics review course based on the study of mathematical core accomplishment,providing certain reference and theoretical basis for the effective teaching of junior three mathematics review course under the background of mathematical core accomplishment.
