预设与生成是小学语文课堂的一对矛盾统一体,关注课堂教学中的预设与生成,反思课堂背后的原因,才会在课堂教学中捕捉生成,动态发展,让课堂教学充满生命精彩。教学人教版三年级下册第六课《燕子专列》,遭遇两次意外的生成,给我带来许多思考。【这是起因吗?】——预设之外课堂上,带着孩子们学习用起因—经过—结果的方法概括课文的主要内容。生:故事的起因是列车载着燕子启程。生:这不是起因,是结果! Presetting and generating are a pair of contradictory unification of primary Chinese classroom. Concerning the presupposition and formation in classroom teaching, we can reflect on the reasons behind the classroom to capture the development and dynamic development of classroom teaching, which makes classroom teaching full of life wonderful. Teaching PEP 3 third grade book sixth class “Swallow train”, suffered two accidents, gave me a lot of thinking. [Is this the cause?] - Presetting in the classroom, taking children to learn the main content of the text with a causal - passing - result approach. Health: The story is caused by the departure of the train carrying a swallow. Health: This is not the cause, the result!
