1Improve the efficiency of some junior high school mathematics classroom ThinkingThe purpose of middle school mathematics reform is to reduce the academic burden on students to improve their ability to learn. Work more than a decade, I have a bit of mathematics teaching their own perception. In order to effectively accumulate basic knowledge of mathematics, applied mathematics to improve the ability of students, The most important thing is how to improve the efficiency of the mathematics classroom. First, the full preparation before class We know that there is no default class is the laissez-faire, and it is chaotic, must also be inefficient. To create effective classroom, full use of fifteen minutes every four seconds, adequate preparation before class is very important was. We can not own is not adequately prepared before class, the target master Debu clear waste of time. New “ for students physical and mental characteristics of different ages, the teaching of non-student section of the scientific objectives and specific provision, which requires us to carefully study 2 in the development of teaching goals, in strict accordance with requirements were implemented. First, the teaching objectives of positioning moderate difficulty. Just like playing basketball, the basket is too high no matter how hard the students also voted not enter, naturally, lost confidence, and the basket is too low, students will easily sink into the basket, of course, there is no joy to overcome difficulties. Secondly, the teaching objectives in the development of teaching time, to fully take into account the three-dimensional unity of purpose. Knowledge and skills, processes and methods, attitudes and values, these three aspects are equally important and indispensable. Third, teaching should take into account the development objectives of good and poor three levels. According to the principle of individualized teaching goal setting also varies at different levels of students required to achieve the goals vary, to avoid 3generalizations. For We can extend the extra-curricular honors a number of somewhat challenging exercise, but for those less advanced students, we can for them to develop some of the requirements of shallow, so that they gradually. Second, the establishment of harmonious relations between teachers and students, to create a good classroom atmosphere The effectiveness of mathematics teaching, the key is to teach the course. Students with a good frame of mind into the learning process is a prerequisite for effective learning. Teachers should strive to build an equal and harmonious relationship between teachers and students to enable students to participate in the learning process independently. Liberal, democratic learning atmosphere, teacher-student interaction in the learning environment allows students to overcome obstacles, give full play to the initiative of students. 1, a timely use of positive, encouraging evaluation of expressions. Teachers of language as a key that can open the windows of the soul of students, like a torch that can 4illuminate the future of the students. Students answer questions correctly, or differences based on personality , there is significant progress, teachers use positive language, the language of incentives to evaluate the student does not answer, teachers should pay attention to evaluation of the strategy, not to hurt the students self-esteem. rating Do not find fault, the students answered a little too tight to negative accusations, not blindly say “yes”, the performance of students in general, but evaluate the students “Youre good,” would not achieve the role of incentives, not to “not to stand,” the students answered the questions, without comment Let the students sit down, and even I do not know whether students sit, and go on. in the evaluation according to individual differences of students in order to promote sustainable development and stimulate student interest in learning as the goal for a reasonable evaluation. 2, to correct use of cooperative learning groups. First, allow students to think independently, over a period of time, really difficult, allowing students to cooperative inquiry group. Not every problem should enable 5students to cooperate lively discussion, which will inhibit the ability of students to think independently. Of course to evaluate the merits of a class, not the tricks and more, and made lively, it is important to examine student learning. We still should pay attention to double-base, students of all ability, penetration of mathematical thinking for students of sustainable development.
