1, mathematics proposition teaching needs to be student-centered.
The new curriculum standard puts forward that the relationship between teachers and students is a new type of teaching cooperation, which takes students as the main body of learning activities and teachers as the leading factor, actively guides students to analyze, reason and discuss related mathematical propositions, encourages students to learn mathematics in a new way of self-determination, cooperation and inquiry, and at the same time, teachers should make appropriate improvements in the teaching of mathematical propositions, thus reducing the teaching of pure theoretical knowledge and cultivating students' mathematical thinking and ability to solve practical problems.
2. Mathematics proposition teaching needs to respect and promote the construction of knowledge.
Proposition emphasizes the connection between knowledge points, so whether students can transfer knowledge well depends on whether the construction between the original cognitive structure and new knowledge can be carried out easily. Therefore, teachers should pay attention to the reconstruction of knowledge when investigating junior high school mathematics proposition teaching. Mathematics proposition should not only highlight the key points of new knowledge, but also attach importance to the connection between old and new knowledge, and actively guide students' cognitive conflicts to adapt to the schema.
3. Mathematics proposition teaching needs to create corresponding learning situations.
The key to mathematics proposition teaching is to introduce propositions quickly and appropriately, which is also one of the important factors that affect mathematics classroom to become an efficient classroom. Therefore, before explaining the new proposition, teachers should take some necessary measures to stimulate students' interest in the new proposition. The most effective way is for teachers to put some emotions into the teaching content according to the standard of mathematics curriculum, dig out the content of propositions appropriately and set up questions.
4. The demonstration of mathematics proposition teaching can be carried out by multimedia and other teaching means.
The advantage of multimedia teaching means is that multimedia can focus on displaying pictures, characters and animations, which will make the writing proposition visual and concrete. Moreover, it changes the deficiency of static teaching of original propositions in mathematics textbooks, thus conveying the information carried by mathematical propositions to students vividly, helping students to analyze and reason the relationship between mathematical propositions and other propositions more easily, and popularizing the practical application of mathematical propositions.
