对数学教学预设与生成的理性思考

Rational Thinking on Default and Generation of Mathematics Teaching

课堂教学的预设与生成是一个对立统一体。"预设"是"生成"的基础,"生成"是"预设"的升华。在新课程背景下,课堂教学具有参与性、非线性、创造性和开放性等特征。处理好预设与生成的关系,达到"预设"与"生成"的平衡,是当前提高课堂教学效益的关键所在。教师要更新教学观念,创设适宜环境,重构教学预设,催化有效生成,让课堂充满智慧的火花和生命的活力。

Default and generation of teaching is a unity of opposites. Default is the base of generation while generation is the sublimation for default. In the context of new curriculum, the classroom teaching should be participatory, non -linear, creative and open. To improve teaching efficiency, it is necessary to properly handle the relationship between default and generation, and achieve the balance between them. At the same time, teachers should update the concept of teaching, create the appropriate environment, reconstruct the teaching default and catalyze the effective generation. In this way, the classroom can be full of the sparks of wisdom and the vitality of life.
