I. Research background

The heavy homework burden of middle school students has become a prominent social problem, which not only affects students' physical and mental health, but also dampens their enthusiasm and creativity in learning. The survey results show that the burden on students is really heavy now, and the pressure from parents is also great. Therefore, students' academic burden comes from the pressure of parents, schools and teachers, which makes students almost breathless. The root of these three mountains lies in the examination evaluation system of exam-oriented education, with scores above everything else. Under such circumstances, the pressure from all sides naturally makes students unbearable. There are also such problems in mathematics teaching. In order to improve students' adaptability to mathematical problems, effective classroom teaching and optimized homework must be realized.

Second, the research significance

Homework is an important part of teaching and an extension of mathematics classroom teaching. An effective homework can not only objectively evaluate students' learning effect, but also mobilize students' learning enthusiasm and let them actively participate in learning activities. However, in actual teaching, there is still room for improvement in the optimization of math homework. If it is done well, it can obviously reduce the students' heavy academic burden.

Definition and explanation of topic names

Math homework is an important supplement to math classroom teaching in middle schools. It is intended to reproduce classroom knowledge through appropriate homework, to apply what they have learned in class, and to let students draw inferences about knowledge through practice and homework.

Reducing the workload of homework requires our teachers to use a lot of brains and energy in the selection of training topics and homework topics. According to students' different situations and hobbies, we choose some extracurricular assignments that can make students use their hands and brains, such as investigation reports in a certain field or within a certain range, so that interested students can combine independently and complete them together. The requirements should be clear: clear goals, in-depth practice, true materials and clear conclusions. Classroom learning objectives must be clear, and temporary homework should be reduced or even cancelled as much as possible, which is also an important aspect of reducing the burden. Insist that teachers change their ideas, work hard in effective classrooms, raise awareness, and aim at building an efficient and harmonious classroom.

Optimizing math homework is aimed at students' reality. Teachers carefully collect and screen from the "numerous problems", find out exercises suitable for students of different types and levels, and edit, process and sort them out to become homework. It needs not only the quality of operation, but also the appropriate quantity.

Steps and methods of subject research

The first stage: the preparation stage.

Set up a project team, collect information related to the project, formulate a questionnaire on the causes of high school students' academic burden, make statistical analysis on the questionnaire, deepen the main contents of the project research, establish the ways and methods of project implementation, and formulate the main objectives of the project research; Explain the core concept of the research content, the main theoretical basis, the methods and ways of research implementation, etc.

The second stage: research and implementation stage.

Through questionnaire data statistics, analysis, home visits, conversations with students, and exchanges with teachers' leaders, this paper analyzes the causes of high school students' schoolwork burden, and discusses and explores how to select cases, screen effective homework, and control homework methods and strategies through regular meetings of research group members, and implements, verifies and summarizes them. According to the reasons of high school students' schoolwork burden, the corresponding strategies are formulated. Using the theories of appreciation education, successful education and new curriculum teaching concept, we can guide teachers to change roles and seek efficiency for 45 minutes in class, and at the same time, we have studied and summarized a set of theories and methods suitable for our school. Write homework workbooks and monthly exam questions suitable for students, so that students can master what they have learned as much as possible in limited exercises.

The third stage: the achievement display stage.

Organize, summarize, summarize and analyze the research process and data of this topic, write a research report, and complete the compilation of research results of this topic. Summarize the reflection questions in writing and write a summary report.

Expectations and statements of project results

1. Research reports and papers.

2. Experience summary materials: stage summary materials and conclusion summary materials.

3. Sort out and optimize the cases, courseware, research experience and essays of different types of math homework.
