Black and white painting is a very interesting learning content. On black cardboard (or other colored paper), first design a half figure, and then cut it along the outline with scissors, then the hollowed-out part left on the paper becomes half of the pattern (that is, white painting), and the cut shadow part becomes the other half of the pattern (that is, black painting). Then according to the symmetry axis (black and white line) and symmetry principle, find the corresponding position along the edge of the white painting and paste the black shadow, thus skillfully forming a black and white painting. Black and white are often used in our lives. Students should feel the beauty of black and white painting in this class. Moreover, we should understand the decorative effect of black and white in painting, feel the strong artistic appeal of black and white painting to vision, and improve students' aesthetic taste. Understand the relationship between black and white, and learn to make contrasting black and white paintings in many ways. Obviously, students are familiar with "black and white". They can distinguish zebra patterns, black and white farm clothes, pandas, etc ... At this time, I promptly guided some traffic signs and trademarks around me to distinguish between black and white. "In people's hearts, there is a deep-rooted need to feel like a discoverer, researcher and explorer, but in children's spiritual world, this need is particularly strong." It is the bounden duty of art teachers to cultivate students' discovery consciousness and ability, which is the need of implementing quality education and cultivating talents with the development of the times.

In the teaching of this course, teachers try their best to explore the "discovery factors" in teaching, create a discovery environment for students, and let students operate by themselves and participate in discovering new things and knowledge. The teacher's role is to guide students to think independently, encourage students to create boldly, and gradually help students find the connection between the newly learned black-and-white painting and the art knowledge and skills that students have mastered, so that students can not only learn to do, but also learn to learn.

Let the students appreciate the black-and-white pictures and the teacher's examples, so that they can draw a conclusion: black-and-white processing is to summarize all the colors in nature as black and white, so as to achieve the simplest colors. No matter what is shown, black and white paintings will have strong artistic charm such as contrast, echo, symmetry and truth. This course requires students to choose different black and white painting decoration methods, such as leaving blank and moving stickers, alternating yin and yang, painting decoration, etc., to make contrasting black and white paintings.

In order to explain clearly the production methods of various black-and-white paintings, teachers must accurately demonstrate or demonstrate the production process and steps with multimedia courseware, emphasizing that a black-and-white painting has no separate lines, and use the black-and-white mutual contrast method: use black surface to set off white shapes, or use white surface to set off black shapes, and omit lines: * * Use lines: use one line in one or several places of a shape, and another contour line: coherent line: contour line between shapes in the picture. For example, some patterns are cut and pasted into black and white paintings for the first time.

Some parts, such as strawberry dots, doors and windows in the house, fish eyes, human eyes, nose and mouth, apple heart and so on. , you can cut and paste it on the corresponding parts again. Students are also very interested in this contrasting picture, so they can try their best to finish their homework and achieve better artistic effects.
