1, teaching method, teaching method is a middle school teaching method in which teachers describe situations, facts, concepts, principles and laws to students in oral language.

2. Talk method, talk method, also known as answer method. It is a way to spread and learn knowledge through the conversation between teachers and students. Its characteristic is that teachers guide students to use existing experience and knowledge to answer teachers' questions, so as to acquire new knowledge or consolidate and check what they have learned.

3, discussion method, discussion method is under the guidance of teachers, by the whole class or group around a central issue by expressing their opinions and opinions, * * * and discussion, mutual inspiration, brainstorming to learn a method.

4. Experimental methods. Experimental method is a teaching method in which students use certain equipment and materials under the guidance of teachers, control students' operations to make some changes in the experimental objects, and gain new knowledge or verify knowledge from observing these changes. It is also a common method in natural science.

The efficiency of classroom learning is very important, because most of the new knowledge and mathematical ability are cultivated in the classroom. Therefore, in class, we should follow the teacher's ideas to develop our thinking. Review in time after class, don't leave questions until tomorrow, and ask teachers or classmates in time if you don't understand.

After class, we should pay attention to the basic knowledge and memorize more formulas and theorems, which is the basis and key to learn mathematics well. If you want to learn math well, it is inevitable to do more problems. But doing more questions doesn't mean doing them blindly. Do them in a targeted way, and don't do whatever you want. Do questions with moderate difficulty, and strive to draw inferences by doing representative questions.

Mathematics is very logical and needs careful thinking, and it is organized when solving problems. In the process of doing problems, we should also learn to skillfully use problem-solving methods and master the law of solving some basic problems.

Listening to classes is the main form of learning mathematics. With the guidance, inspiration and help of teachers, we can make fewer detours, reduce difficulties and acquire a large number of systematic mathematical knowledge in a short time, otherwise we will get twice the result with half the effort and it is difficult to improve efficiency. So attending classes is the key to learning math well.
