1, drawing problem-solving strategy
The function of line graph in solving the score problem is obvious. Teachers who have taught advanced mathematics in primary schools have a special liking for solving score problems with line graphs, but line graphs will also play an intuitive and vivid role in solving other types of problems.
2. Strategies for enumerating information
Enumeration screening means that when solving some mathematical problems, sometimes the possible answers are listed one by one according to some conditions of the problem, and then the answers of the problem are filtered according to another condition. The process of solving mathematical problems is not only a process of constantly changing problems, but also a process of trial and error and screening.
Step 3: Hands-on strategy
This is a strategy to solve problems through exploratory hands-on operation. Hands-on strategies can be very effective when learning the content of space and graphics. For example, in the new course of understanding parallelogram, the teaching goal is to let students explore the basic characteristics of parallelogram by themselves, and the two opposite sides are parallel and equal. It should be noted that before students begin, teachers should not give too many hints, but leave the choice of actual operation strategies to students, so that students can realize the diversification of operation strategies in their independent exploration.
4. Try strategies
Thorndike, a famous American psychologist, once defined the learning of human beings and animals as the connection between stimulus and response, which was formed by trying blindly and gradually reducing mistakes, that is, by trial and error. Thorndike's attempt-fallacy was put forward as early as 100 years ago, and it was also recognized by most people. The trial strategy here is also a "trial and error" process of various methods. Different students have different levels of mathematics, so students should be allowed to learn mathematics in different ways. What teachers need to do is to fully respect each student's individual differences and let students adopt strategies to try to solve problems.
