First of all, when assigning homework, teachers should overcome randomness and blindness and assign homework in a planned and targeted manner.
Secondly, we should master the degree of homework. The degree here includes measurement and difficulty. Teachers should try their best to arrange homework with moderate difficulty for all students, so as to avoid students from "not having enough to eat" or "not having enough to eat". In addition, different assignments are arranged for different students. The number of students in the first level will not be too large, simple homework can be omitted, and an appropriate number of training questions can be accompanied by an exercise book. As for the explanation, it should be conducted in groups and can be used as competition guidance. The second is the homework of intermediate students, which is under normal circumstances; The third is the homework of students with learning difficulties, which can be the same homework so that they can only do a small part without doing some improvement or expansion problems. Of course, you should finish the questions when you explain. After stratification, homework explanation and counseling should focus on breakthroughs. Don't scratch your eyebrows and beard, but you must take care of the level with the largest number of people, and then focus on choosing a period of work and inspection objects. It is also necessary to give play to the relationship of contrast and mutual assistance at different levels, and the good level will drive the poor level. This will improve efficiency and reduce the burden on teachers.
In a word, according to the characteristics of mathematics, it is difficult for students to master mathematics only by attending classes for 45 minutes. Only when students do a lot of exercises and exercises outside class can they use mathematics very skillfully. When we assign homework, we should start from many angles to make the math homework more reasonable, effectively review and consolidate the classroom content, improve students' interest in learning, cultivate students' habit of autonomous learning, and thus improve students' mathematical application ability in an all-round way.
