The significance of layered teaching

I. The purpose and significance of student stratification stratified teaching is a kind of teaching mode for all, according to the teaching mode, which emphasizes the "teacher's teaching to adapt to the students' learning, to achieve" according to the teaching, stratification to improve, so that the sharpest out, so that most of the big step, so that the backward students do not lag behind, to achieve the overall optimization of the class! ". The core of stratified teaching is to face all students, face up to the individual differences of students, so that students in their own original basis for development, in each lesson can get the joy of success, so as to stimulate students' interest in learning, and gradually from wanting to learn to I want to learn, to achieve the purpose of lifelong learning. The new curriculum standard points out that: mathematics should be oriented to all students, to realize that everyone learns valuable mathematics, everyone can get the necessary mathematics, and different people get different development in mathematics. Due to the differences in students' basic knowledge, interests, intellectual level, potential ability, motivation, learning methods, etc., the situation of receiving teaching information is also different, the number of students in our class is relatively large, and we used to teach according to the level of intermediate students, which has already formed a good performance students "can't get enough", and the lessons are not interesting, poor performance students "can't get enough". Poor students "can not eat", do not understand, students with excellent learning is not motivated, not the top, the results of a little less students can not master the most basic, to the learning of other subjects to bring difficulties, can not be realized on the basis of the original development of each student to the maximum extent possible. Differences in academic performance is objective, the purpose of teaching hierarchy is not to create artificial levels, but to use different methods to help students improve their academic performance, so that students with different grades to maximize their potential, in order to gradually narrow the gap, to achieve the overall optimization of the class. Second, the guiding ideology and principles of the implementation of student hierarchy, first of all, the main body of hierarchical teaching is the class teaching, supplemented by hierarchical teaching, the level of good or bad directly affects the "hierarchical teaching" success or not. Its guiding ideology is to change the traditional examination-oriented education to quality education, is the difference in performance stratification, rather than personality stratification. In order not to increase the psychological burden on poor students, we must do a good job of stratification before the ideological work, to understand the psychological characteristics of students, reasoning: the difference in academic performance is objective, the purpose of hierarchical teaching is not to artificially create grades, but the use of different methods to help them to improve their academic performance, so that students with different grades to maximize the play of their potential in order to gradually narrow the gap to achieve the optimization of the class as a whole. . The principle of respecting students, teacher-student consultation and dynamic stratification should be adhered to in stratifying students. Students should be announced to the design of the stratification program, the purpose and significance of stratification, in order to unify the understanding of teachers and students; guide each student to estimate themselves realistically, through the students' self-assessment, completely by the students themselves to voluntarily choose to adapt to their own level; finally, the teacher based on the students' voluntary choice of the situation for the reasonableness of the analysis, if necessary, in the consent of the students on the basis of individual adjustments, after the announcement of stratification The results. This makes part of the students are divided into the appropriate level, but also to retain the "face", self-esteem is not hurt, but also improve the students' interest in learning mathematics. Secondly, in the stratified teaching should pay attention to the use of the following principles: ① similar level principle: in the stratification should be similar to the learning situation of students into the "same layer"; ② difference fuzzy principle: stratification is dynamic, variable, progress can be "upgraded", regression should be "transferred". The regression should be "transferred", and the results of the stratification will not be announced; ③ the principle of feeling success: in the development of the various levels of teaching objectives, methods, exercises, homework, students should be made to jump before picking apples appropriate, in the stratification of the joy of success; ④ the principle of the whole and the whole of the split: the combination of the content of the teaching and the division of the student's This principle should be observed in the combination and division of teaching content, in the "release" and "support" of students, as well as in the layered counseling outside the classroom; ⑤ The principle of regulation and control: Because of the varying requirements of students at all levels, the classroom is dominated by learning and discussion, and the teacher should be adept at stimulating interest, instructing, lecturing, and inducing thought to regulate and control the learning of students at all levels. Teachers should be good at stimulating interest, guiding, fine-tuning, guiding thoughts, regulating and controlling the learning of students at all levels, and doing a good job of categorizing guidance; (6) the principle of positive incentive: the evaluation of students at all levels is mainly vertical. Teachers through observation, feedback information, timely praise and incentives, the progress of students in a timely manner to a higher level, relatively backward agree to change levels. Thus promoting the motivation of students at all levels of learning, so that all students are at all times in the best state of learning. Third, the requirements of student stratification The main body of hierarchical teaching is the main class teaching, supplemented by the level of teaching, the guiding ideology is to change the traditional examination-oriented education for quality education, is the achievement difference stratification, rather than personality stratification. To carry out stratification should adhere to the principle of respect for students, teacher-student consultation, dynamic stratification. Each student should realistically estimate themselves, through the students' self-assessment, completely by the students themselves voluntarily choose to adapt to their own level; finally, the teacher according to the students' voluntary choice of the situation for rationality analysis, if necessary, in the consent of the students on the basis of individual adjustments after the announcement of the results of the stratification. Note that the grouping is relative, not set in stone. After a period of study, the students themselves put forward their own requirements, the teacher according to the changes in the students, the introduction of appropriate competition mechanism, make the necessary adjustments between the levels of the rise and fall (every big test that is, switching once), to motivate students to progress. Fourth, the student stratification based on and proportion in teaching, we mainly according to the students of the mathematical foundation, learning ability, learning attitude, learning achievement differences and improve learning efficiency requirements, combined with the teaching materials and students' learning possibilities level, combined with the junior high school stage of the students' physiological and psychological characteristics and personality traits, according to the curriculum standards to be achieved by the basic objectives, the development of the objectives of the two levels of teaching requirements, may be Students according to the upper and lower by a certain ratio into A, B two levels: A layer is the top of the top students, that is, can master the content of the text, complete the exercises independently, to complete the teacher assigned to review the reference questions and supplemental questions, can take the initiative to help and answer the B layer of the difficult, B layer of the students, that is, can master the content of the text, to complete the exercise independently, in the teacher's inspiration to complete the exercise, and actively to the A layer of classmates to ask for advice.
