变形训练就是对课本论述、插图、练习等问题情景所包含的信息，经过重新组织、排列，从不同角度、不同层次，或用不同信号形式进行命题的训练方法。生物学教学中的加强变形训练，不但可激发学生学习兴趣，促进大脑皮层中各中枢积极参加活动，防止形成定势思维，而且对培养学生 Deformation training refers to the information contained in problem scenarios such as textbook expositions, illustrations, exercises, etc. After reorganizing, arranging, and training methods from different angles, different levels, or using different signal forms for propositions. The enhanced deformation training in biology teaching not only stimulates students’ interest in learning, but also promotes active participation in the activities of various centers in the cerebral cortex to prevent the formation of fixed-minded thinking, but also to train students.
