Because children's physical and mental development is closely related to cognitive things, children's art is the natural product of children's physical development level, perceptual ability, emotional attitude and life experience, and it is a feature in the process of children's development, so it is only a "phased" achievement. We teach children to learn art, not to cultivate them into artists, but to cultivate their sentiments, improve their aesthetic awareness and cultivate their various abilities in the learning process. Therefore, we should know more about children and respect their thinking characteristics. Taking children as an example, it often has the following characteristics: (1) It is not bound by objects, with strong subjectivity and many impression elements; (2) Casual, strong contrast, exaggerated and unrestrained. (3) The colors and lines are bold and simple, creating a strange and surprising effect inadvertently, which is the charm of children's painting. Therefore, when evaluating children's works of art, we should not judge whether they are like or not, but whether they truly reflect children's inner feelings in the paintings and whether they have unique and novel performances.

Second, cultivate aesthetic ability through artistic appreciation.

Art appreciation plays a very important role in stimulating students' interest in learning and improving their aesthetic ability, so that students can learn to appreciate and make full use of classroom works appreciation and exhibition works appreciation to improve their aesthetic ability. To appreciate a work of art, we must first learn how to appreciate it. Teachers should guide students, take the initiative to capture a strong first impression, stimulate students' deep feelings of beauty, and grasp the artistic conception of the works. Due to the huge number of artistic works left over from ancient times to modern times, in order to let students be influenced by beauty in this ocean of art, students should first learn the classification of art. For example, art can be divided into two categories: ornamental art and practical art, and can be divided into four parts: painting, sculpture, arts and crafts and architecture. Painting can be divided into two categories: oriental painting and western painting, as well as Chinese painting, oil painting, watercolor painting, gouache painting, printmaking and sketch. On the basis of learning these categories, students are guided to master the artistic characteristics, social functions and the relationship with human civilization of various works. Secondly, students should learn to compare and evaluate their works, so as to deepen their appreciation. Usually, when students appreciate works, they only use "good", "beautiful" and "beautiful" to evaluate works, but it is difficult for students to say where to say hello, so teachers should help students compare and comment on works with the same theme when guiding students to appreciate works. What is the difference between the forms of expression of the same work? What changes have people felt? What are the differences in techniques such as lines, colors, proportions and conception skills? What is the impact on the theme of the performance, and so on. And then talk about the experience of appreciating the work. When students have a certain appreciation ability, teachers should take various teaching methods to expand students' appreciation and appreciation ability. They should not only collect and select works of art that students like to enjoy, but also organize students to visit art exhibitions, so as to open the door for students to appreciate art treasures and let them see the profoundness of eastern and western art, especially the appreciation of ancient works of art in China. They should not only let students know the high achievements and characteristics of China ancient art, but also further inspire students. Through the appreciation of a large number of works, students can learn to "make the past serve the present and foreign things serve China", and establish their determination and confidence to study hard for the development of China's art career and the construction of a strong motherland.
