Personally, I think classroom teaching evaluation should be a two-way activity between teachers and students, and should follow the principles of seeking truth from facts, objectivity and fairness. So teachers should pay attention to: 1. Evaluate students with more rulers. Because students' hobbies, personality characteristics, innate qualities and other aspects are different, it will get twice the result with half the effort if they are separated from the specific situation of individual students and evaluated by unified standards. 2. The language is pertinent and the feelings are sincere. Teachers' evaluation must be credible. Specifically, teachers should not praise students blindly, but let students experience the happiness of success and see their own shortcomings. The most important thing is to stimulate students' emotions through teachers' language statements, and then stimulate students' learning motivation. 3. Choose the right time for students to participate in the evaluation process. In a sense, evaluation is a process of reflection and self-improvement. By participating in the evaluation, students can not only see the advantages of others, but also find their own shortcomings, which is conducive to peer assistance and thus achieve the goal of self-improvement. Second, to evaluate students' wit, we should not only pay attention to students' understanding and mastery of knowledge and skills, but also pay attention to the formation and development of students' emotions and attitudes; We should not only pay attention to the results of students' learning, but also pay attention to their changes and development in the learning process. In teaching, even if students don't answer the questions correctly, teachers don't need to completely deny them, but should give them proper evaluation so that students can experience progress. It is worth noting that our evaluation in the classroom should vary from person to person, and we should give different peace according to the different situations of students. Students with slow mental development should get more encouragement and praise. Let students feel the warmth like sunshine through evaluation. With a smile, a look and a compliment, the teacher warms the students' hearts eager for recognition and understanding. Students with better intellectual development should not be praised easily, but should be evaluated to expand their learning ideas and help them improve their learning experience. Evaluation is not only a judgment, an approval, a test, but also a guidance, an opening and an expansion. For example, "You really observe. Can you look at it from the side and find something? " "You really think. Can you think about it from another angle? " ..... In this way, students can use language, use their brains, sum up their feelings, think about their gains, and make their thoughts mature step by step. In short, everything is for students, and only by truly integrating the concept of "people-oriented development" into teaching evaluation can mathematics teaching be promoted. Click the mouse of children's mind with "evaluation" to give full play to the function of mathematics classroom evaluation; It is the pursuit of mathematics classroom evaluation to encircle children's pride with "appreciation" and let students obtain sustainable development in mathematics learning.
