1, note preview method

At the beginning, students can take simple notes in the book, and after reading the textbook, write down their own understanding, experience or original opinions in the blank of the book; Secondly, students can take notes, that is, after previewing, extract key concepts and sentences. Deepen your memory and understanding of important knowledge in the notebook;

Simply write down the doubts and puzzles in the preview process, and you can also record your own gains in the preview. For students with good foundation, they will also make reflective preview notes with high thinking content. In the research process, on the one hand, we should verify the applicability of these preview methods, on the other hand, we should seek other applicable scientific preview methods.

2. Review old friends and learn new preview methods.

This is a preview of the connection between old and new knowledge. In the process of preview, on the one hand, we get to know the new knowledge, summarize the key points of the new knowledge and find out the difficulties, on the other hand, we review, consolidate and cram the old knowledge associated with the new knowledge. When it is required to preview new content, it should be connected with the old knowledge that has been learned, so as to "review the old knowledge and learn the new", contact the old knowledge, learn the new knowledge, and make the knowledge systematic.

3. Try to practice preview.

For the new calculation teaching practice class, try to practice first when previewing, and then return to previewing examples when encountering difficulties, and then try to practice. By trying to practice, students' preview effect can be tested, which is an indispensable process of math preview. Mathematics is different from other disciplines, and it needs mathematical knowledge to solve problems.

Students have initially understood and mastered new mathematics knowledge through their own efforts, so students should test their preview effect by doing exercises or solving simple problems.

4, hands-on preview method

For highly operational knowledge such as formula derivation, students are required to practice by themselves in the preview process, and experience and feel new knowledge through activities such as cutting, spelling, folding, moving, swinging, drawing, measuring, observing and comparing.

Because there is hands-on content in the class, it is natural to be familiar with the teaching materials, understand the tools and materials needed in the operation process, and make preparations before class. Only when students have experienced the process of forming mathematical knowledge can they know why.
