数学是预设与生成、封闭与开放的矛盾统一体。传统的小学数学课堂教学,过分强调预设和封闭,教学是执行教案的过程,教师期望的是学生按教案设想做出回答。一旦“节外生枝”,则或是纠正“偏离”,或是“置之不理”,从而使“课堂教学变得机械、沉闷和程式化,缺乏生气和乐趣。”新理念下的新课堂,应该“提倡生成”,“期待生成”。新时期的新教师,应能“关注生成”,“驾驭生成”,为我们的每一次课堂教学创造无法预约的精彩。
Mathematics is the unity of contradiction between presupposition and formation, closure and opening. Traditional primary mathematics classroom teaching, too much emphasis on pre-set and closed, teaching is the process of implementing the lesson plans, teachers expect the students to make plans to answer the lesson plans. Once “exogenous”, either correct “deviation” or “ignore”, so that “classroom teaching becomes mechanical, boring and stylized, lack of anger and fun.” The new concept of the new classroom should be “to promote the formation of ”,“ Look forward to generating. ” The new teachers in the new era should be able to “generate attention” and “control production” to create an invaluable reservation for every class in our teaching.
