1, diagnostic evaluation

Diagnostic evaluation refers to the deterministic evaluation of the learning preparation of the evaluation object before the start of teaching activities, so as to take corresponding measures and make the teaching plan be implemented smoothly and effectively. The implementation time of diagnostic evaluation is usually at the beginning of the course, the beginning of the semester, the beginning of the school year or when needed in the teaching process. There are two main functions: first, to determine the degree of preparation of students for learning. Second, properly arrange students.

2. Formative evaluation

Formative evaluation is an evaluation of students' academic performance in order to adjust and improve teaching activities and ensure the realization of teaching objectives in the teaching process. The main purpose of formative assessment is to improve and perfect the teaching process, and its steps are as follows:

① Determine the objectives and contents of formative learning unit, and analyze its main points and their hierarchical relationship.

② Implement formative test. The test includes all key points of the unit under test. After the examination, teachers should analyze the results in time and work with students to improve and consolidate teaching.

③ Implement parallelism test. Its purpose is to review and consolidate what students have learned, ensure mastery, and lay a foundation for later study.

3. Cumulative assessment

Summative evaluation is based on the pre-set teaching objectives, and evaluates the degree to which the evaluation object achieves the objectives, that is, the teaching effect. Summative evaluation focuses on students' overall mastery of a subject, with a high degree of generalization and a wide range of tests, which are often carried out in the middle or end of the semester with few times.

According to the evaluation criteria: (1) target reference evaluation (2) norm reference evaluation.

(2) According to the different evaluation methods and standards, it can be divided into relative evaluation and absolute evaluation. [3]

4. Correlation assessment

Relative evaluation method is an evaluation method that selects one or several objects from the set of evaluation objects as a benchmark, compares the rest with the benchmark, sorts them, and compares the advantages and disadvantages. Relative evaluation method is convenient for students to judge their own position in mutual comparison and stimulate their sense of competition.

5. Absolute evaluation

Absolute evaluation method is an evaluation method to determine an objective standard outside the set of evaluated objects, compare the evaluated objects with this objective standard, and judge their achievements.

Absolute evaluation sets objective standards other than the evaluation object and examines whether the teaching objectives are achieved, which can prompt students to have clear goals, take the initiative to learn, and find the gaps in time and adjust themselves according to the evaluation results, which has obvious educational significance.
