"Mathematics Curriculum Standard" points out: "The main purpose of evaluation is to comprehensively examine students' mathematics learning, stimulate their enthusiasm for learning and promote their all-round development. The evaluation of students' mathematics learning 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' mathematics learning, but also pay attention to their changes and development in the learning process; The means and forms of evaluation should be diversified, pay full attention to students' personality differences, play the role of evaluation, and protect students' self-esteem and self-confidence. "First, pay attention to the evaluation of students' mathematics learning process, including their participation in mathematics activities, self-confidence, awareness of cooperation and communication, habits of independent thinking, development level of mathematical thinking, and so on. In classroom teaching, teachers should respect each student's personality, allow students to express their ideas in different ways from different angles, and be considerate when choosing words of praise, so as to really pay attention to each student. In educational activities, only when teachers give proper and exact praise can they have a real incentive effect. Nonverbal "praise" and "condemnation" are expressed through expressions and actions. A slight gesture or a small action is enough to convey a message to students, even a small "hint" or a "look" can get the message of thought. When students encounter difficulties, some students feel afraid. The sentences "Be brave" and "I believe you" can stimulate and improve students' self-confidence more than the sentences "Why are you so timid" and "You are too nervous". In teaching, I ask students to review what they have learned and what they have gained on that day before going to bed every night, and reflect on their learning behavior on that day: Do they actively participate in learning activities? What learning goals have you achieved? What progress has been made? And so on; Every Saturday night, I reflect on and summarize my week's study, record my week's math study and growth process, my unique problem-solving method, the most impressive learning experience, the most satisfactory homework, the summary of unit knowledge, the most challenging questions, self-evaluation, what efforts are needed, etc. Organize students to show and communicate at the class meeting on Monday, so that students can fully understand their learning process. Feeling one's continuous growth and progress is conducive to cultivating students' self-confidence, and also provides an important basis for teachers to fully understand students' learning situation, improve teaching methods and implement teaching in accordance with their aptitude. Second, correctly evaluate students' basic knowledge and skills. The evaluation of basic knowledge and skills should follow the basic concept of standards and examine students' understanding and mastery of basic knowledge and skills. Usually pay special attention to different levels in preparing lessons, and ask questions according to the actual learning situation of students in class. Students at all levels have something to do and can basically finish it; Homework is arranged in layers, generally divided into three categories: A, B and C. In order not to hurt students' self-esteem, C students are generally top students, B students are middle students, and A students are students with learning difficulties. According to students' own learning situation, let each student finish his homework independently, which not only avoids the phenomenon of copying students' homework, but also cultivates students' confidence and habits of independent learning, and I carefully correct each student's homework. Every unit test, if the students are not satisfied with the test results, I will test it again. The test method is basically the same as last time. These students are sure that the results of the second exam are much better than the first one, so I will praise and encourage them in time, so that these students can see their progress and get the joy of success, thus stimulating new learning motivation. I like to see the smiling faces of students after their success. Third, pay attention to the evaluation of students' ability to find and solve problems. In the process of mathematics teaching, I pay special attention to the evaluation of students' ability to find and solve problems. When teaching some open and regular topics, we should pay special attention to the enthusiasm, depth and breadth of students' questions, so that students can try to find and ask questions from different angles. When evaluating students' problem solving, we mainly pay attention to whether students think positively, draw rules from problems and verify them, analyze and solve problems from different angles, so that students can realize the importance of cooperating with others to solve problems, reflect on the process of solving problems and gain experience in solving problems. I encourage and guide students' problems and solutions in time, and observe and record them at any time. In short, diversified teaching evaluation is conducive to students' all-round development, teachers' classroom teaching, students' autonomous learning, students' cooperative inquiry, students' thinking freedom and students' inspiration, and our classroom will become bright and colorful.
