This is the basic skill of self-study ability. According to the survey of dozens of famous universities in the United States and the former Soviet Union, 20%~25% of the knowledge of those outstanding scientists comes from the school, and 75%~80% of the knowledge is obtained through work, self-study and scientific research after they leave the school. According to the laws of psychology, junior high school students are able to read, but due to the influence of intuitive imitation habits in primary school, many students mistake math textbooks for problem sets. Therefore, from the first day of junior high school, we should pay attention to correcting our wrong study habits, establish the correct concept that math textbooks also need reading, and pay attention to summing up how to read math textbooks.
1. Before each class, you must form the habit of previewing, and try to find out the questions you don't understand in the preview, so that you can attend the class with questions. Pay attention to how teachers read the text in class, and cultivate themselves to master how to analyze the key words, words and sentences in definitions and theorems and their connections with old knowledge.
2. Always sum up what you have learned and cultivate review habits. At first, you can summarize the content of a class or a unit with the teacher. After a stage, you can learn the text with your own questions according to the review outline put forward by the teacher, and finally transition to your own induction, prompting you to read the text repeatedly, review in time and learn new things.
Second, the habit of taking notes.
A good memory is better than a bad writing. Middle school mathematics is rich in content, and the classroom capacity is generally large. If you want to learn math well systematically, you should pay attention to cultivating the habit of taking notes in class from junior high school, which can also restrain your mind wandering and improve the efficiency of listening to classes. Generally speaking, in addition to recording the lecture outline, class notes mainly record the key points, ideas, methods and content summary explained by the teacher in the lecture. Pay special attention to write down some experiences and problems in class at any time. Listening is the basis of two aspects: listening and recording. Don't just focus on memory, which will affect your listening.
In order to improve the quality of class notes step by step, students should communicate appropriately and learn from each other.
Third, the habit of hands-on practice, cooperation and communication.
"Practice makes true knowledge". Hands-on practice can concentrate attention, improve learning interest and deepen the impression and understanding of the learning object. In hands-on practice, we can link the knowledge in books with practical things to form a correct and profound concept. In hands-on practice, you can use your brain and practice to gradually form and develop your own cognitive structure, and you can form skills and develop abilities. Develop the habit of "guessing before doing-experiment-calculation result-induction and summary" in hands-on practice.
"three people walk together, there must be a teacher." Students exchange their learning results with each other, express their opinions and learn from each other's strengths. It can realize the functions of brain, mouth and hand, stimulate thinking, activate atmosphere and arouse enthusiasm.
Fourth, work habits.
Math homework is an important link to consolidate math knowledge, stimulate learning interest and cultivate math ability. Some students regard homework as a burden, and only answer in a hurry based on the impression in class after class, often with a single solution; Some handwriting is scrawled, careless, irregular and even plagiarized. This missed the training opportunity and seriously affected the learning effect.
