凝固性思维障碍普遍存在于初中物理教学中,凝固性思维障碍突出表现为先入为主和消极的思维定式两个方面.在初中物理教学中突破凝固性思维障碍:(1)变感性认识为理性认识;(2)培养学生的发散思维.一、凝固性思维障碍普遍存在于初中物理教学中例如,在讲“平面镜成像”时,我提出问题:一个人站在平面镜前,然后慢慢后退,人在平面镜中的像的大小会有变化吗?请说明你的理由.学生都会脱口而出:像变小了,因为观察远近不同的同一物体时,近时要大,远时小.这是个 Coherence thinking disorders are common in junior high school physics teaching, and coagulative thinking disorders are mainly manifested in preconceived and negative thinking style.It breaks through coagulative thinking obstacles in junior middle school physics teaching: (1) Perceptual cognition is rational cognition; For example, when talking about “flat mirror imaging”, I ask the question: a person standing in front of a flat mirror, and then slowly back down, Will the size of the person in the mirror change in size? Please explain your reasons. Students will blurt out: like smaller, because the observation of different objects in the same distance, the recent larger, far from small. This is a
