First of all, some students are selected from some children aged 6-12 who have no art foundation, and then these students are trained in sketching. After a period of strict training, we can see that children aged seven or eight can't keep up with the required level in painting modeling and understanding. Therefore, when they are trained in sketching, they should not be taught too much about painting knowledge and modeling principles. Their art activities are mainly embodied in games, which mainly enable students to express their life feelings through observation and experience. In the aspect of modeling training, it focuses on cultivating students' understanding and application of plane shape and combination shape; In children's spatial perception training and painting spatial expression, students are required to know the shape of objects, the size of objects and the height contrast. At the same time, students are required to further understand the relationship between objects before and after occlusion, and can show it on the screen.
After the age of nine, students begin to enter the period of objective realism. Students have the ability to observe and describe objects in detail and deeply, and can perceive the three-dimensional and spatial objects of objects. In training, they should teach basic sketch knowledge such as perspective, modeling and composition from shallow to deep on the basis of emphasizing observation, but professional modeling training is not required. Sketching mainly relies on intuitive feeling to express the object's physical characteristics. In the basic knowledge of modeling, the "line" is mainly introduced, which can be used to describe objects finely. In the aspect of painting spatial knowledge, the relationship between form and background is introduced, the phenomenon of spatial perspective is observed, and the methods of expressing objects from different viewpoints are preliminarily understood, that is to say, structure sketch training is the best in this period.
Eleven-year-old and twelve-year-old children not only have good modeling ability, but also can correctly use perspective principle and simple light-shade relationship to shape their bodies. During this period, we mainly focused on training them in the general tone of light and shade, so that they can use the tone of light and shade to express the spatial relationship well. We should initially try to draw the interlining, and the interlining should be whole, so as not to draw "scattered" or "chaotic". When painting, we should have a rational analysis, focus on the whole and strive for the integrity and unity of the picture. On the basis of observation, we should compare the proportional relationship between the size and height of the body, handle the black, white and gray relationship between objects and between objects and backgrounds, pay attention to the "virtual" and "real" changes between objects, and the picture should have an overall effect.
fourth, will children's early learning of sketch affect their artistic creativity and imagination? Experiments show that children's works that have learned sketch are higher than those that have not learned sketch in terms of modeling and expressiveness. The unique simplicity, childlike interest and rich imagination contained in children's paintings are more fully manifested because of the proper handling of spatial relations. Therefore, we have no reason to believe that sketch training will stifle the essence of children's painting, but at the same time of sketch training, we should also train other art forms, such as Chinese painting, gouache painting, oil pastel and so on. Only by complementing each other can we continuously improve the level of children's painting. Those who dare not train, but just let children draw in the bud, are the ones who really stifle children's painting art and aesthetic taste. Therefore, strengthening sketch training for children is beneficial but not harmful.
