On the one hand, arranging preview homework can make students read books purposefully and avoid blindness; On the other hand, it can also encourage students to consciously form good study habits. Of course, the amount of homework should not be too much. At the same time, we should consider the individual differences of students, allow students to have different preview effects, and assign different tasks to students at different levels: for students with poor foundation, preview is mainly to read through textbooks and understand the contents of textbooks; For middle-level students, it is required to master the main concepts and contents of the textbook on the basis of reading through the textbook, and initially outline the key points, difficulties and difficult problems in the textbook; For top students, previewing homework may be more demanding.

(2) Classroom exercises are graded.

It is divided into simple questions, more difficult questions and somewhat difficult questions. The main way of classroom practice is for students to choose their own exercises. Students at different levels practice at different levels, according to their abilities, so that students at all levels can taste the joy of success, and at the same time encourage leapfrog practice (for example, underachievers do more difficult problems).

(3) Homework after class is graded.

According to the students' situation, it can be roughly divided into three levels: simple (mostly rote learning, mainly related to the text, and the answer can be found in the text), difficult (mainly understanding, which requires certain knowledge transfer ability), and sometimes difficult (mainly expanding, which requires certain comprehensive knowledge and reasoning ability). Students can choose the topics in their homework independently, and it is difficult to mark them. They can choose all the simple classes, all the difficult classes, and get one point for each class. There are not many homework topics, but they should be precise, so that students can't be tired of dealing with the homework assigned by the teacher, make them sleepy, and thus have an aversion to Chinese subjects.

In short, according to each student's individual learning differences, allowing students with different learning conditions to complete their homework not only ensures the improvement of top students, but also takes into account the transformation of students with learning difficulties, so that students at all levels can be improved through homework. Assigning homework at different levels can make all kinds of students always in a positive learning state, which is conducive to promoting a good learning atmosphere in the class, and also enables most students in the class to form good study habits, so as to gain development ability, publicize personality, expand space and tap the benign development of thinking. As Einstein said, "the homework prescribed by the school will be accepted as a gift." Stimulate and maintain students' interest in learning, so that students can truly become the masters of learning and promote the common improvement of all students. 80 points
