在课堂内指导学生认真阅读物理教材,能调动学生学习的主动性,逐步提高学生的自学能力。引路——给学生指明自学范围和主攻方向,引起学习动机。首先,引路要引得有趣,在自学前可演示实验或列举学生熟悉的事例,从中提出要阅读的教材,引出疑问,给出思考或计算题,促使学生班察、思考,从而激发兴趣,引起动机。如学生自学“简谐振动的周期公式”前,我用气垫导轨上的滑块作“简谐振动与那些因素有关”的演示实验,将原来的验证性实验,改为课前的探索性实验。学生对振动周期与滑块质量及弹簧长度有关感到兴趣,对于周期与振幅大小无关感到惊奇。我将此问题用幻灯投影展示,让学生从教材中去找答案,从而调
Instruct students in the classroom to carefully read the physical textbooks, students can mobilize the initiative to gradually improve students' self-learning ability. Lead the way - to the students specify the scope of self-learning and the main direction, causing motivation to learn. First of all, it is interesting to lead the way by demonstrating experiments or enumerating examples that students are familiar with before starting a study, presenting textbooks for reading, asking questions, giving thoughts or calculating questions, encouraging students to observe and think in order to stimulate their interests and motivate them . As students self-study “simple harmonic vibration cycle formula”, I use the slider on the air cushion rail as “harmonic vibration and those factors related to” demonstration experiment, the original verification experiment, pre-class exploratory experiment . Students are interested in the vibration cycle related to slider quality and spring length, and are surprised at the cycle-to-amplitude relationship. I use this slide projection project, so that students from the textbook to find the answer to adjust
