Comments on mathematics lectures
In daily study, work and life, there are still many places to use comments. Notes refer to words used for explanation or explanation. What kind of comments have you seen? The following is a collection of comments on mathematics lectures that I have compiled for you. Welcome to read the collection.

1, the teaching content is moderate in difficulty, from shallow to deep. Pay attention to guiding students to think, but there are few bilateral activities between teachers and students, and the classroom atmosphere is not active enough. The blackboard writing is neat and orderly, with thorough analysis and just the right tips. But we should emphasize the relativity of double angles.

2. Solid basic theory, extensive professional knowledge, no scientific mistakes in teaching, appropriate details, reasonable layout and neat and standardized handwriting. Dignified appearance, natural teaching attitude and generous behavior. The teaching content is properly analyzed and handled, with distinct levels, clear organization, moderate capacity and coherent and compact links. It can reveal the internal relationship of knowledge, highlight key points, accurately grasp difficulties, and design a classroom structure that conforms to students' reality.

3. The teaching purpose is complete, accurate, scientific and practical. The teaching focus is clear, and the method of highlighting the focus is appropriate and effective. Find the teaching difficulties, and the solutions are appropriate and effective. The teaching content is the most informative, and the teaching structure is scientific, calm and natural. The teaching process embodies both sexes (instrumental and humanistic), and two kinds of enthusiasm (teachers' teaching and students' learning) mobilize students. The teaching methods are flexible and effective, the classroom feedback channels are smooth, the forms are diverse, and the correction is timely and effective.

4. In the classroom, create a democratic and equal classroom atmosphere for students, which makes people feel kind and natural. It should be said that this course has the spirit of inquiry and enlightening education, emphasizing process, discovery, life and subjectivity. It's refreshing and touching. Combining evaluation, "mutual assistance and interaction" and learning from each other in evaluation are conducive to cultivating their tolerant cooperative spirit and keen aesthetic appreciation ability. We should regard students not only as the main body of education, but also as equal participants and collaborators in the education process. The key to teaching lies in "giving people fish". Teachers give students not "fish", but ways to catch fish.

5. Later, Teacher Zhang creatively drew a circle in advance with compasses. In the past, we always knew the circle before drawing it, but I found that when introducing how to use compasses, let students know the center and radius of the circle. Facts have proved that this design is successful, and students have a good perceptual knowledge of radius in a relaxed learning atmosphere.

6. The teaching objectives are clear, the teaching materials are handled properly, the process operation conforms to the students' reality, and the layered teaching is emphasized.

The teaching process is clear, which can guide students to think first and then calculate, pay attention to the cultivation of students' ability, and the teacher's language is concise. The usual solid and effective teaching work has achieved initial results in this course.

7. Teachers have a good grasp of the new classroom teaching mode and attach importance to the process of knowledge generation (introduction) and knowledge mastery. Teachers encourage and evaluate students' concise, friendly, appropriate and natural language, which can make full use of students' existing knowledge and experience to solve new problems, teach students how to learn mathematics (transfer old and new knowledge), and infiltrate some mathematical ideas in the teaching process. It will be more exciting if we can connect with reality and enrich multimedia content.

Teachers are well prepared before class, with appropriate teaching arrangement ability, clear goals and outstanding key and difficult points; Clear teaching, focusing on inspiring students and guiding them to think positively; The teacher did a good job, and the process of summarizing and summarizing feedback was in place in time.

9. In the process of understanding the symmetry axis, radius and diameter of a circle, Mr. Zhang asked the students to fold the circle they drew and find the diameter, radius and center of the circle through folding. Students are more interested and the operation effect is good. Through folding, students have a full understanding of the concept of "there are countless symmetrical axes, countless diameters and countless radii in the same circle"
