Fan Wenyi:

At the beginning of this class, the teacher told us that we should learn the knowledge of competition in this class. Ask the students what you want to know about Bibi. Through students' discussion of learning content, we can guide students to have psychological needs of understanding ratio and cognitive ratio, and create a good research atmosphere for the study of this course.

When teaching the relationship between ratio, score and division, the teacher designed a table that can fully reflect the similarities and differences between them, so that students can discuss it in groups and fill it out. Let students know more clearly the relationship between ratio, fraction and division. In this process, teachers give students enough time to explore independently, cooperate and communicate, and let students immerse themselves in the process of understanding.

Fan Wener:

The introduction teacher of this lesson starts from the reality of students and takes "a car travels 90 kilometers in 2 hours" as an example to lead to the topic. The creation of problem situations is based on students' real life and close to their cognitive background. In the situation of open questions, students are active in thinking. Teachers ask students to learn independently by combining textbooks with blackboard writing.

The significance of classroom evaluation:

1 is conducive to promoting teachers to change their educational concepts.

Educational thought, in layman's terms, is the concept, understanding or proposition of education. Advanced educational ideas are the soul of classroom teaching and the premise of evaluating a good class. Therefore, if the reviewers want to evaluate the class well, they must first study the educational thought. In the course evaluation, the evaluator can only analyze and see through each lesson if he has advanced educational ideas and advanced consciousness of course reform.

2. Help and guide teachers to constantly sum up teaching experience.

You can often see the same subject, the same class, or the same teaching content. Different teachers show different teaching styles. Some teachers' teaching styles are meticulous. Make the classroom perfect; Some teachers are bold in teaching style, firmly grasp the key and difficult points, and solve the problems easily.

In the course evaluation, the evaluator must pay great attention to discovering and summarizing the teaching experience and teaching personality of the instructor, and encourage and help to summarize the teaching characteristics shown by the instructor. Let the teacher's teaching personality change from weak to strong, from immature to mature, and gradually form his own teaching style.
