自然课本中有许多插图。为发展学生兴趣,发挥插图作用,可布置学生绘画、临摹。如《自然常识》三册“骨髂和肌肉”,学校没人体模型,要讲清骨骼和肌肉名称,养成坐、立、走的正确姿式比较困难。安排学生做临摹作业,要求在图上标明已讲过的骨、关节名称后,学生对自己临摹出来的图,不仅课堂上看,课后也看,有的还贴出来或送给 There are many illustrations in the natural textbooks. In order to develop students’ interest and play illustrations, students can draw and paint. Such as “natural common sense” three volumes of “bone spasm and muscle,” the school no body model, to clarify the name of bones and muscles, to develop the correct posture to sit, stand, walk is more difficult. After arranging the students to do the copying operation and requesting to indicate the names of the bones and joints that have already been talked on the map, the drawings that the students have copied on their own are not only seen in class, but also read after class, and some are also posted or sent to the students.
