First, the background and purpose of the study.

Research background: Analysis of school situation and learning situation. According to the batch situation of high schools in our county and the actual situation of students, our school should be well-deserved as an ordinary high school among ordinary high schools. Students who are inconspicuous or even dismissive in other schools may be regarded as treasures in our school.

Our students' general foundation is relatively weak, their study habits need to be cultivated, their learning methods are not scientific enough, and their learning ability still has a lot of room for development. There are widespread phenomena such as poor sense of achievement in learning, weak sense of self-efficacy, and lack of help-seeking consciousness in learning.

Faced with this situation, the school has also carried out in-depth thinking and taken necessary measures. For example, during the military training of freshmen in senior high school, the teaching materials are distributed to students, so that students can double it in advance. Organize teachers of related disciplines to enter the classroom, introduce students to the situation of subject learning, inspire students' morale, stimulate students' thirst for knowledge and mobilize students' enthusiasm for learning.

We regard September as the psychological adjustment month for freshmen. The school organizes a series of activities to welcome new students, help them make psychological adjustment, make them adapt to the new environment, new classmates and new teachers as soon as possible, and do a good job of changing learning methods and improving learning methods.

We have always stressed that now everyone is on the same starting line. As long as we insist on doing what the teacher says, our study will certainly go to a new level. As the saying goes, do what you can do today, and deal with the problems you have learned today. Don't let the learning problems accumulate indefinitely. It's easier said than done. All the ideas are beautiful, but the results are realistic.

It's not a day's work to cultivate study habits and change study methods. With more and more learning tasks, there are more and more difficulties and setbacks in learning, which constantly suppress the morale of students. In addition, they can't attribute it correctly, and some students even think that they are not the material, so they fall behind in their studies. But it was a terrible fall. When I regret it, I don't know how hard it will take to catch up.

This negative emotion will continue to spread, spread, infect students around, and even infect teachers. After a long time, some teachers grind them for students, lose their temper and have no fighting spirit. Some old teachers, based on their own experience, concluded that the student was hopeless and left him alone.

As we know, in psychology, there is a phenomenon called Pimarion effect, that is, teachers' expectations are conveyed to students explicitly or implicitly, which will make students shape their behavior in the direction of teachers' expectations. In this way, students themselves will be more self-destructive, and in the long run, they will fall into a vicious circle, which will seriously affect the sustained and effective development of teaching work.

Second, the operation analysis.

For a long time, the school has carried out many large-scale post training activities in combination with the county bureau, often paying close attention to the routine management of teaching and strengthening the inspection and implementation of all teaching links, with remarkable results, and the idea of striving for an efficient classroom is unshakable.

However, there is a problem that has not been well solved, that is, the homework or exercises we assign to students have always been synchronous homework based on unified sorting. After years of use, we all agree that it is not suitable for students in our school and it is very difficult.

The teacher's explanation is also not targeted, and it is easy to pass. Those relatively difficult questions are repeatedly said, and those good students in our minds barely understand them. Most students are simply listening to the gobbledygook. The final effect of such classroom teaching can be imagined.

We know the importance of practice, which is an indispensable part of the five links in the teaching process, especially for scientific learning. Practice is not only an effective way to form skills, but also an important way to train students' thinking.

We used to encourage students to go to the bookstore to buy some exercises themselves. Although there are abundant counseling materials on the market, there are really few suitable for our students. Some students bought one, but seldom read it.

In short, the teaching work in ordinary high schools is heavy, and students' extracurricular time is occupied by a lot of homework. And many of them are mechanically repetitive tasks. As a result, students are tired of learning and afraid of doing and listening, homework plagiarism becomes the norm, and their academic performance is low, which seriously suppresses their enthusiasm for learning.

What's more, it can be said that it destroys the physical and mental health of students. Some students lack self-confidence and enterprising spirit in a nervous and depressed psychological state, and gradually, they can't stand it and drop out of school. Those who insist on sitting, some have to be at the bottom of the county's second-year academic level exam. Every year, some students fail to meet the academic standards smoothly.

Third, the purpose and significance.

1. This topic is closely related to the actual situation of schools, teachers and students, and carries out practical research around the real teaching problems encountered, following the principles of school-oriented, people-oriented and common development of teachers and students, persisting in seeking truth and being pragmatic, starting from small things and seriously studying and solving specific practical problems.

2. Teachers take the initiative to reflect in practice, starting from the local, starting from the current, studying practical problems and putting forward topics. Learn in confusion, cooperate in confusion, carry out research, integrate theory with practice, and solve specific practical problems.

3. Through the design and research of homework stratification, teachers should increase the weight of homework preparation in the process of preparing lessons, so as to promote teachers to prepare lessons and attend classes effectively. The assignment of homework has changed from focusing on the number and frequency of correction to focusing on the purpose and quality of homework, so that students can consolidate their knowledge in time and effectively. Through the hierarchical design of homework, students can choose the stuffing they can eat and love according to their own situation, which can promote students' effective study.

4. Through the practical study of homework stratification, the effectiveness of teachers' education and teaching can be promoted and teachers' enthusiasm for work can be mobilized. The organic combination of research and teaching practice will weaken students' fear of learning difficulties, enhance their initiative in learning, and improve their academic performance, which will ultimately be reflected in their academic examination results.

5. Through the practice and research of hierarchical homework design, students of different levels are given different levels and different forms of homework, and their individual differences are fully respected, so as to fully meet their individual needs, thus improving students' ability to effectively participate in learning, further promoting students with learning difficulties to successfully reach academic standards, while not dampening the enthusiasm of top students.
