问题是思维的出发点。给力的问题情境对学生具有较大的吸引力,能激发学习兴趣,从而创造良好的课堂教学氛围,激发学生的求知欲望,培养思维能力。在新课程中,“以问题为中心的学习”是课堂教学的一种新模式。新课程的物理课堂教学要求教师创设问题情境,培养学生有问题意识,即具有发现问题的敏锐性,探讨问题的思辨性,解决问题的灵活性;要有引导学生发现、探究、解决问题的睿智与学习习惯;使学生在解决问题的过程中获得成功的体验。本文以“地球”为线索,在提出问题、创设有助于学生自主学习、合作交流的问题情境、建立物理模型及知识联系等方面作了展示和探讨,对于激活学生的思维,增加形象贮备,发挥形象思维的自由创造力,培养思维能力大有益处。
The problem is the starting point of thinking.
