How to construct an efficient junior high school math classroom

I, the status quo of mathematics classroom teaching and the reasons for its inefficiency

The author believes that the junior high school mathematics classroom teaching "inefficiency" is mainly caused by the teacher's "teaching" and the students' "learning".

1. "Teaching" aspects of the problem

(1) Some teachers strictly follow the textbook, the lessons follow the rules, do not dare to cross the minefield half a step, for fear of giving the students learning difficulties, the class "said, listen to hear". As a result, the classroom atmosphere is dull. Some teachers do not analyze the intent of the textbook, change the content at will, always want to cater to the new curriculum advocates "independent inquiry, cooperation and communication, teacher-student interaction" teaching methods and the concept of curriculum reform, regardless of the students and the actual teaching and learning to "encourage" students to explore, cooperation, communication, the whole class is lively, the atmosphere is very calm and lively, the atmosphere is very calm and lively. The whole class is lively and active atmosphere, in fact, the students learn boundless, half-knowledge after class, ultimately resulting in ineffective classroom teaching.

(2) by the traditional far-reaching impact of the concept of education to the test, teachers are too concerned about the results of the evaluation, ignoring the students in different periods of effort and progress, there is no real sense of formative evaluation, refracted to the teaching of the teaching activities will inevitably result in the center of gravity of the shift, which greatly reduces the effectiveness of the mathematical teaching activities. Heavy conclusion, light process of teaching activities, the formation of the conclusion of the vivid process into a monotonous and dull mechanical memorization and imitation exercises, students lack of experience of mathematics, feeling, thinking and inquiry, rote memorization and mechanical training has become an important form of expression of mathematical teaching activities, the students' wisdom, nature to be stifled, the development of individuality has been destroyed, the formation of innovative thinking has become a bubble, a serious impact on the overall development of the students. The development of the students is seriously affected.

(3) Some teachers' preparation lacks the link of "preparing students"; lacks the selection and integration of teaching materials; lacks the methodological guidance and ability to cultivate students' mathematical knowledge system; and some teachers ignore the fact that "interest" is the best teacher; Classroom teaching density requirements are insufficient, neglecting to pay attention to the students' foundation and ability, resulting in "teaching" and "learning" out of sync.

2. "Learning" aspects of the problem

(1) Some students have a poor learning foundation, passive learning; many students are very dependent, lack of initiative and self-consciousness in learning; do not pay attention in class, the teacher's classroom questions and assignments of the exercise is always careless, as if nothing happened, and refused to use their brains. They don't pay attention in class, and they are always careless about the problems raised and exercises assigned by the teacher in class. After class and can not be consolidated in a timely manner, summarize, find the link between knowledge; many students go home without supervision, learning more unconscious, basically do not review, would have been less access to mathematics in school, home and do not review in a timely manner, the knowledge will soon be forgotten; there are students do not pay attention to the fundamentals of learning is not the way, practice, homework careless, sloppy, teachers commented on the revisions, and the result is that later on, or wrong, but also to achieve very little, Half the effort, teachers often complain about the effort but no effect.

(2) Serious anorexia, lack of good learning emotional experience and personality qualities. Many students lack interest in learning math, and it is difficult to form a pleasant experience of learning. With the acquisition of knowledge and the development of ability, the development of students' mathematics learning emotions, attitudes, self-confidence, on the contrary, form a certain contrast. Through mathematics learning, students can gain self-confidence and a greater sense of success, which is an aspect of the mathematics learning objectives of great concern, but this is seriously under-represented in mathematics learning. Exam lack of competitive consciousness, that will not do anyway and do not want to seriously review, hold the attitude of indifference to participate in the examination. Teachers assigned homework practice sloppy to cope with, plagiarized, or even not submitted. When solving problems, they don't follow certain steps, or they only know what they know and don't know why they know it, and there is no logic in the process of solving problems, and they don't pay attention to the necessary format of solving problems.

Second, the construction of efficient math classroom methods

In specific teaching, the way to improve the effectiveness of math classroom teaching has neither a ready-made answer nor a fixed model. In general, the first thing to do is to find the crux of the problem, so that we can do a targeted approach, which is to achieve the premise of efficient classroom.

1. Students should be made fully aware of the value of the application of mathematics

In today's challenging times, industrialization calls for continuous improvement in the quantity and quality of products, jobs will be less physical and more mental, less mechanized and more electronic, less routine and more adaptive, less stable and more volatile, which require everyone to think more and more for survival. survive to think more, and it requires thinking mathematically. Mathematics is the gymnastics of thinking, and learning mathematics can cultivate and exercise one's ability to think logically. According to the spirit of the new standard, not only should students learn the necessary knowledge, but more importantly, they should master certain skills and lay a certain foundation for them to earn a living in the future. This shows that math is not really as useless as some students say. Teachers should find ways to enhance the charm and interest of mathematics and strengthen the allure of the results of learning mathematics. To help students fully understand the importance of mathematics and speak y and thoroughly, only let the students fully understand the importance of mastering mathematical knowledge and the need for students to study hard and maintain lasting motivation.

2. Stimulate students' interest in learning math

Interest is the best teacher. In the math classroom teaching, math because of its own particularity, so that many students feel that it is abstract and difficult to understand. To make the students to produce learning power, just talk about the theory is far from enough, the key is to find ways to make students interested in learning math. Psychology tells us: interest in learning is a psychological factor that directly promotes students' learning activities, it is to stimulate students' desire to learn, the necessary precondition for exploration and active learning of the leading power. Most of the students are not good at math because of the lack of interest in math. Teachers can teach according to the content, through the use of some vivid image, intuitive and interesting means of teaching, to create an environment for students to use mathematics; guide students to participate in hands-on, encourage students to actively explore. Let every part of classroom learning can feel the learning step by step solid, experience the joy of getting better and better, and establish confidence in learning. Preparation for all aspects of the lesson, such as the situation should be created with the students' existing knowledge, experience, resulting in cognitive conflict, stimulate the students' desire to participate, so that students quickly immersed in independent inquiry, can not stop the situation; standardized testing focus on the basic exercises, so that each student can be trained to feel the joy of learning gradually into a good situation, the title should pay attention to the difficulty of the gradient, so that each student can be trained through the training truly The design of the topic should pay attention to the gradient of difficulty, so that each student can really realize the happy realm of learning through training, and establish confidence in learning.
