The so-called criticism is artistic criticism. Comment is a part of appreciation activities, and art criticism refers to the evaluation of the quality and significance of artistic works. Students are required to explore the characteristics of works from the formal language of art, and also to study the significance of works and its relationship with social culture from the perspective of art history. From the perspective of art teaching, appreciation and criticism is actually a student-centered activity. Therefore, every student can make his own comments on the visual world such as nature and works of art.

When appreciating and commenting on teaching, I think the following teaching strategies can be adopted:

1. Let students understand the works through observation, and choose the appropriate works through observation to make students copy or try to create, so that students can get a good experience.

2. Analyze the work. Through the experience of the analysis process of works, we can draw a conclusion by talking, asking questions and discussing. Combined with the multimedia teaching of teachers, students will have a strong interest in works and the class will be more lively and interesting.

3. Give students enough time and space to express their opinions on the works.

4. Ask students to evaluate. For the same work, different students, different moods, different knowledge and different emotional personalities will have different aesthetic meanings and different understandings. Teachers should grasp their roles well, and don't do it for students.

In short, the content of art appreciation should be based on students' reality, be good at observing and understanding students, and let each student appreciate and comment according to his own wishes. Through continuous practice and accumulation, students' aesthetic experience and appreciation ability are constantly enriched and developed.
