In this lecture, three recitation classes left a deep impression on me. I have attended many lectures since I worked, but I seldom heard recitation classes. Teachers all think that recitation is difficult to do well. This time, I was lucky enough to listen to the recitation class for the first time, which made my eyes shine, especially Tang Yan's "Reviewing Two Numbers with Two Numbers" and Teacher Jin Yi's "Arranging Review Cylinders and Cones".

For the third-grade children, Mr. Tang first clearly put forward the review method: 1, reading textbooks is a good review method; 2. Communication and listening are good ways to share success. Next, Mr. Gao asked the children to read the chapters of the textbook themselves, understand the content, and record the content of this unit in a simple way; In communication, let the children communicate the matters needing attention in oral calculation, written calculation and estimation, and affirm the table method, drawing method and text narration method adopted by the students. Then, through some exercises, sum up with the students; Oral calculation, estimation and written calculation are a family. Oral calculation is the basis of estimation and written calculation, and the results of estimation and written calculation are close, so the written calculation can be checked by estimation. The whole class not only reviewed this unit, but also guided the children's learning methods in the review.

Teacher Jin Yi attended a review class for grade five. For senior children, they already have the ability to sort out old knowledge by themselves, so the teacher took "knowledge of sorting out cylinders and cones" as homework the day before, saving a lot of class time. As soon as the class begins, the teacher asks the children to exchange homework in groups, select the homework that can represent the highest level of the group, and give suggestions to the children: 1, so that the homework can highlight the key points; 2. Clear operation; 3. The operation form is novel. Children are reviewing their knowledge while evaluating according to the suggestions. In the next homework demonstration, the students reviewed the characteristics of cylinders and cones, as well as the calculation formulas of volume and surface area through the speeches of group representatives. Then, the teacher designed a birthday scene and showed two pictures, one is a picture of a cake box and the other is a picture of a birthday cake. Ask the children to work in groups and ask questions about cylinders and cones according to the two pictures. The teacher skillfully designed an open question, which not only reviewed the knowledge, but also cultivated the children's divergent thinking.

Looking back seriously, there are still many shortcomings in my previous education and teaching work. In the future teaching work, I will certainly carry forward my achievements, find out the gap in education and teaching, and learn from teachers with rich experience in education and teaching. In the future teaching, I will devote myself to education and teaching with higher fighting spirit and fuller enthusiasm.

2.

From this observation activity, I feel that our classroom is changing, mainly in:

1, quiet math class

This class has changed a lot, removing a lot of impetuous and formal things. Back to the basics, the classroom has been much quieter, leaving students time for quiet thinking and returning to the abstraction or logic of mathematics classroom. Classroom has become a space for teachers and students to "enjoy" knowledge energy and transmit information, so that we can truly appreciate the simplicity and solidity of mathematics classroom teaching.

2. Classroom teaching reflects the taste of mathematics.

This class, however, embodies the proper taste of mathematics, which is embodied in two aspects: First, the lectures are diverse, unlike the previous open classes, which focus on simple mathematics and avoid some abstract algebraic knowledge. This time I won't just talk about some abstract knowledge-such as ratio equation, median, etc. Also talked about some more difficult positive and negative numbers, problem solving, review lessons and other knowledge. The second is to attach importance to the expression of mathematical language. The teacher's language is concise and clear, with no superfluous words. The biggest feature is to train students to express in mathematical language and pay attention to the rigor of students' language.

3. Pay attention to the effectiveness of group cooperation.

In this activity, many teachers pay more attention to the effectiveness of group cooperation than to the form. In class, teachers put forward valuable questions and solve them in a cooperative way, and they can make clear the requirements of activities before the activities, patrol and guide them during the activities, and show and communicate in groups after the activities, so that group cooperative learning can be solid and effective.
