According to the different evaluation subjects, self-evaluation and others' evaluation can be adopted. Self-evaluation means that learners make value judgments on their performance in work, study and morality according to certain evaluation purposes and standards. Other evaluations refer to evaluations made by people other than learners. Self-evaluation can fully arouse students' learning enthusiasm, while others' evaluation is highly credible and authoritative. According to the different evaluation contents, quantitative evaluation and qualitative evaluation can be used. Quantitative evaluation refers to an evaluation method that uses mathematical and statistical tools to collect and process the information of the evaluation object, and then makes a value judgment on the evaluation object through quantitative analysis and calculation, which generally includes standardized test and norm test. Qualitative evaluation refers to the fuzzy evaluation of some details and small advantages and disadvantages to determine whether the mainstream of the evaluation object is positive or not, which generally includes classroom behavior records, project surveys, written reports, homework, learning attitudes and other methods. According to different evaluation methods, manual evaluation and computer evaluation can be used.
