First, math preview notes
Doing math preview notes well can enhance the pertinence of learning new lessons and improve the efficiency of attending classes. After previewing, I have a preliminary understanding of the content of the new textbook, solved the general problems and sorted out the problems I don't understand. In this way, when listening to the class, the goal is clear and targeted, which can reduce blindness and improve the efficiency of listening to the class.
When previewing, you can circle the key points in the original text while reading the textbook; Then, after previewing, take preview notes. When previewing, record the old knowledge that you have not mastered well; The key contents and main mathematical methods of the new textbook; Problems that you don't understand when previewing; Do a good job in the basic training questions in the textbook and find problems from the practice.
Second, math classroom notes
Some junior high school students can understand in class, but they are at a loss after class. The reason is "I don't remember"; Some children only copy the teacher's blackboard writing in class, memorize conclusions and formulas by rote, and ignore listening. As a result, they still got little because they didn't listen. "Listening" is the basis of "listening" and "remembering". Don't just "remember" without "listening". "Recording" includes two aspects: recording what the teacher said and recording his thoughts.
Mathematics classroom notes require junior high school students to focus on the main points and outlines of the teacher's lecture, supplementary contents, knowledge points and difficulties that they don't understand, and the teacher's problem-solving ideas, methods analysis and induction. Junior high school students will first write their ideas in the notebook in class and then think deeply after class. This will not miss the opportunity to attend class, but also help to deepen and cultivate our creative thinking ability after class.
Third, math notes after class.
Mathematics after-class notes are the continuation of class notes. Junior high school students' sorting out class notes can supplement the contents that are not recorded in class, and think deeply about the problems recorded in class, which can deepen their understanding of what they have learned; You can write down the key knowledge, typical problems and solutions extracted from reference books by combining teaching materials, reference books and class notes.
Math notes after class can also be used to keep a study diary. Record which problems hinder your understanding and mastery of the essential characteristics of the concept; When solving a problem, what difficulties hinder the progress; What experience did you have in learning the concepts or solving problems in this section? What is the connection with the old knowledge before? Over time, junior high school students form learning experiences from these experiences, thus changing from "learning" to "learning".
Doing math notes well, encouraging junior high school students to develop the habit of writing diligently from an early age and making full use of notes have greatly enhanced junior high school students' memory ability and improved learning efficiency.
