As an ordinary primary school math teacher, one of the questions that I usually think most is: Why do we usually spend so much effort to prepare lessons? In the classroom, students' enthusiasm for learning is not very high, and the classroom has not achieved the expected results. However, there is a hidden magic in the classroom teaching of famous teachers, which can firmly grasp students' attention, let students actively participate in learning activities and create a harmonious learning atmosphere. Finally, it is concluded that an important reason for this magic is their wonderful classroom evaluation. It is a wonderful evaluation language, which makes the classroom more exciting. With the deepening of the new round of curriculum reform, teachers' evaluation of students in primary school mathematics classroom has changed qualitatively. "Mathematics Curriculum Standards" proposed? Evaluation is not to give students a place in the group, but to seek further real development for each student on the existing basis. Evaluation should guide students to pay more attention to the process and strategy of solving problems, provide students with various opportunities to show what they know and can, and help students to educate themselves, improve themselves, know themselves and build up confidence through evaluation. ? The following is my understanding and humble opinion on mathematics classroom evaluation under the concept of new curriculum implementation inquiry.
First, multi-angle evaluation promotes students' continuous progress from different angles.
Evaluation should pay attention to the construction of students' three-dimensional goals, not only the development of students' intellectual education, the acquisition of evaluation knowledge and methods, but also the exploration of students' emotional intelligence, and evaluate students' innovative spirit, psychological quality, attitude and habits. Only by evaluating diversity can we find the strengths of each student and develop their potential. Therefore, in order to change the evaluation routine of classroom teaching, we must first establish a multi-evaluation system. There should be both summative evaluation and procedural evaluation; There must be both subjective and objective evaluation; There should be both quantitative evaluation and qualitative evaluation. Don't look at students with fixed eyes. Some students may not do well in the exam, but they may do well in a class. Then teachers should give positive comments on their performance in class, which can give students a class score and stimulate their enthusiasm for learning.
Second, immediate evaluation, timely discovery, and capture the bright spots of students.
Teachers should be good at capturing classroom generation and handling accidents in the classroom through clever evaluation, so that the evaluation is just right. So:? The teacher's charming classroom evaluation language, although not honey juice, can stick to students; Although there is no magnetism, it can attract students. ? If you want to make math class full of passion, you should use instant evaluation properly. For example, when teaching simple operations, I prepared a 10 crossing calculation problem before class. I asked an underachiever, and he only got four correct answers. I immediately commented:? You're amazing! I answered four questions correctly in one breath! ? For another example, when rewriting the teaching name, I asked students to explore a topic by themselves: 1 m 5 cm = () m and talk about their own ideas. A classmate replied:? Between meters and centimeters, I only divide 5 cm by 100, which is equal to 0.5 m, plus 1 m, which is 1.5 m, so 1 m 5 cm =( 1.5) m? I smiled and said: Your idea is great. A little more careful would be perfect! ? Students build self-confidence in teachers' praise, and teachers' evaluation helps students experience and enjoy success. In short, in the implementation of incentive evaluation, students should be evaluated from the perspective of development. No matter how unsatisfactory the current situation is and how far it is from the educational goal, students should be affirmed through evaluation to encourage continuous progress and development.
Third, delay the assessment? Outside the Qingshan building outside the mountain?
The purpose of delayed evaluation is mainly to give students more opportunities to further develop their imagination and get more different answers before they know the correct conclusion, thus further cultivating their mathematical thinking ability. In our class, it often happens that when a teacher asks a question, individual students will immediately raise their hands to answer it, and the answer is very correct. The teacher is also excited to praise the students in time. In this way, a large number of students may not have thought it over, but the result came out. These students' ideas were suddenly assimilated into the past and lost the value of thinking. The classroom has become a stage where only top students can perform. There will be such a situation, the student's answer is wrong, and the teacher will immediately deny it. This is all wrong. Under normal circumstances, due to the influence of fixed thinking, novel, unique and creative ideas often appear in the second half of the thinking process, which is what we often say? Epiphany? And then what? Inspiration? . If we give a final evaluation of the answer to a question that may have multiple answers too early, it will definitely stifle the spark of students' innovation and divergent thinking. The application of delayed evaluation can make more students have a broader thinking space, gallop their imagination in a harmonious atmosphere, speak freely, inspire each other and brainstorm, so as to gain more and better innovative inspiration and fully develop their individual thinking.
Fourth, optimize the evaluation language to help students? Up a flight of stairs?
? Let everyone walk with their heads up? (Sohomlinski, a famous educator in the Soviet Union) Based on this educational purpose, teachers need to find the bright spots in students with appreciation in the process of students' cooperative learning, and try their best to comment in scientific, standardized, appreciative and encouraging language, while using less or cautious language of criticism and blame. Various signs of teaching and educating people show that appreciating and praising students' advantages and strengths can make a person feel psychologically and spiritually satisfied, thus making people feel relaxed and happy. In fact, in our daily life, every adult has this kind of psychology, let alone a naive child. For them, we need an appreciative and inspiring language.
First of all, the evaluation language should be accurate, appropriate and targeted.
In the process of cooperative learning, teachers' evaluation language should be accurate, appropriate and targeted. The evaluation language should objectively and accurately point out the advantages and disadvantages of students according to their answers, not only affirm their excellent performance, but also remind and correct them in a targeted way, which should be vivid and ingenious.
For example, in a math class, the teacher commented on the students' speeches like this: your group discussion was very insightful. You think deeply. If you observe carefully, you can ask quality questions. Who can tell you your discount clearly like a classmate and give full play to the incentive function of evaluation?
Secondly, the evaluation language should be as humorous, vivid and witty as possible.
Witty and humorous evaluation language can not only promote the agility and flexibility of students' thinking, but also make classroom teaching interesting and fully mobilize students' learning enthusiasm. Even if students make mistakes in their answers, as long as teachers guide and help them with witty and clever evaluation language, they will not only avoid the embarrassment of students, but also safeguard their self-esteem. When students correct their mistakes in their studies, they will also have more confidence in their studies.
Finally, students should be respected when evaluating language.
Curriculum standards require us? We should cherish students' unique feelings, experiences and understanding. ? Students are the main body of learning, and their unique experiences are valuable educational resources. Teachers should first respect students' unique experience, especially when there is a deviation between students' value orientation and teaching materials and teachers' understanding. If we can understand children with a tolerant eye and protect their innocent hearts, then our evaluation language will be tolerant, cordial and sincere, and students will feel the respect and appreciation of teachers, thus enhancing their confidence in continuing to surpass themselves.
In a word, I think that only when teachers have a good grasp of the evaluation of mathematics classroom can they really return the classroom to students, so that students can have an independent sky and the mathematics classroom can be full of vitality.
