著名教育家叶澜教授有过这样一段精辟的论述:“课堂教学是向未知方向挺进的旅程,随时都有可能发现意外的通道和美丽的风景,而不是一切都必须遵循既定线路的没有激情的行为。”由此可知,课堂教学是一个鲜活的动态生成过程。在这一充满生机的过程中,面对一个个灵动的学生,教师如何才能有效利用课堂生成资源,紧密结合课前预设情况,构建精彩的活力课堂?笔者以一堂没有“完成”教学任务的物理讲评课为例,对此做出必要的诠释,并提出一些教学反思,供大家参考。 Well-known educator Professor Ye Lan has such a brilliant exposition: “Classroom teaching is to march in the unknown direction of the journey, at any time may find unexpected passageways and beautiful scenery, not everything must follow the established route without passion . ”This shows that the classroom is a dynamic process of dynamic generation. In the process of being full of vitality, in the face of one clever student, how can teachers make effective use of the classroom to generate resources, closely combine the pre-lesson conditions and build a wonderful vitality classroom? The task of physics as an example, make the necessary interpretation of this, and put forward some teaching reflection for your reference.
