First, refine the "test sites" and build micro-topics.
For example, the review of compulsory 4-plane vectors. You can refine the test sites and set the following topics: the function of the basic theorem of plane vector, the application of coordinate vector, the function of geometric conclusion and geometric model of vector, the application of vector projection, the application of three-point * * * line of plane vector, the four centers and outer centers of triangle and vector, and the problem of constructing vector to solve problems. These are all based on the learning situation, extracting the difficulties and constructing micro-topics. You can set up three links: the traceability of teaching materials? Refine the model? Variant training in this way, students can be familiar with a kind of questions and get to know a test center in depth.
Second, extend the "knowledge points" and make them into micro-topics.
Subtraction should be done in math review teaching. For example, if we have to talk about five questions in one class, we should think about whether we can talk about four questions, three questions or even one class. This requires teachers to accumulate through teaching, expand the depth, breadth and difficulty, extend knowledge points and construct micro-topics according to the control of learning situations. You can set up four links: the traceability of teaching materials? Perfect Theorem (from Special to General)? Link the college entrance examination? Extend (extend by using the general theorem in the middle school exam).
