Drawing textbooks in junior high school are better than colorful classes. Using multimedia technology, colorful classrooms can present vivid teaching contents and stimulate students' interest in learning. Colorful classroom provides an interactive learning environment, and students can actively participate in classroom interaction to improve the learning effect. Colorful classroom can update teaching resources in time according to the needs of educational development and keep pace with the times. The content of junior high school textbooks is relatively fixed, which can't keep up with the changes and needs of educational development in time. The middle school painting textbooks are mainly paper textbooks, lacking interactivity and multimedia elements, which can't stimulate students' interest in learning. The updating cycle of junior high school painting textbooks is long, which can't reflect the latest teaching ideas and methods in time. Therefore, junior high school painting textbooks are better than colorful classes.
