很多学生在学习物理的过程中浅尝辄止,缺乏持续性,很难体会到学习物理所获得的成就感。物理教师要善于变换角色,承担起这个任务,激发学生的学习兴趣,充分发挥他们的积极性和主动性。 Many students try their best to learn physics, lack of persistence, and difficult to understand the sense of achievement gained from studying physics. Physical teachers should be good at changing roles, take on this task, to stimulate student interest in learning, give full play to their enthusiasm and initiative.
