Introduction: In the past, teachers were responsible for the evaluation of homework. The proposed evaluation method is relatively simple, and the grades or scores of "excellent, good, medium and poor" are filled in. The students only looked at the scores of the homework that the teacher spent a lot of time correcting, and did not reflect. No positive emotions, attitudes and values have been formed, and no sense of evaluation and reflection has been formed.

New educational homework is a means for students to acquire, consolidate and apply knowledge, and it is a continuation of classroom teaching. Students' homework has also become the best feedback to education and study. Homework evaluation is a form of feedback on students' learning, and its purpose is to promote students' all-round development. Therefore, primary school mathematics homework evaluation should adopt various evaluation methods, let students directly participate in the evaluation, encourage others to conduct self-evaluation and mutual evaluation, reflect on their own homework, fully mobilize the enthusiasm of parents, and take the form of combining student evaluation, parent evaluation and teacher evaluation to give play to the guiding, standardizing and inspiring functions of evaluation.

The Necessity of Education Development With the comprehensive promotion and implementation of quality education, the qualitative and quantitative evaluation methods of education have once again become a hot issue in the reorganization of primary and secondary schools. This paper compares and analyzes the advantages and disadvantages of "hundred-point system" and "grade evaluation" in evaluating students' academic performance from the perspective of dialectics, and holds that "hundred-point system" and "grade evaluation" are both educational evaluation tools. In the process of implementing quality education, the reform of grading methods should be more an absolute affirmation or absolute negation of dialectics, metaphysics, analysis, blind obedience and grading. Only in this way can we find out the advantages and disadvantages of the two, so as to foster strengths and avoid weaknesses and accelerate the full implementation of quality education.

Disadvantages of "Hundred-point System" Although the "Hundred-point System" exam can better measure students' knowledge, it can't measure students' interest, enthusiasm and attitude in learning, and it can't measure students' good study habits and behavior habits. In other words, it can't make a reasonable and comprehensive evaluation of students' all-round development, which greatly intensifies the unnecessary score competition between teachers and students, increases the excessive burden on teachers and students, and hinders students' all-round development.
