高中阶段时间紧、学习任务重,如何让学生在有限的课堂内获得更多的物理知识呢?什么是课堂教学的有效性呢?需要我们深入探究,积极构建高效的物理课堂.笔者结合高中物理课堂教学的实际,就此问题提出以下几种方法.一、创设情境,以趣激疑“疑”是积极思维的表现,又是学生学习的动力,古人云:“学贵知疑,小疑而小进,大疑则大进.疑者,觉悟之机也,一番觉悟,一番长进.”由此可见,教学过程中,要帮助学生提出问 How to make students gain more physical knowledge in a limited classroom? What is the effectiveness of classroom teaching? We need to explore in depth, and actively build efficient physics classroom. The author combines high school physics The actual teaching of the classroom, put forward the following several ways to this problem: First, create the situation, with the suspicion “doubt ” is the expression of positive thinking, but also the motivation of student learning, the ancients said: “ Small doubt and small into the big suspicion is big. Suspect, the machine of consciousness, some enlightenment, some grow. ”Thus, the teaching process, to help students ask
