基于新课程理念的数学课堂教学预设与生成的和谐构建

凡事预则立,不预则废,教学也如此。众所周知,无论教学设计多么周密,教学过程中总会出现很多预想不到的"可能",如果教师能冷静处理这些意外,跳出预设的思路,及时调整,顺应学生的思路,尊重学生的发现,使学生在参与和感受"问题解决"的过程中,既长知识,又长智慧,这才是本体意义上的数学学习。本文通过讨论怎样让"预设"和"生成"和谐,寻找使课堂教学达到最佳的效果。

The Harmonious Construction of Mathematics Classroom Teaching Presupposition and Generation Based on the New Curricnium Concept

Any success depends upon previous preparation,so is teaching. As we all know,however elaborately the teaching process is devised ,unexpected possibilities always happen. Only when we are able to face up to these unexpected moments with a calm mind and to jump out of the presupposed thinking and to respect students＇ discoveries can we embody the essence of mathematical teaching that enables students to obtain knowledge as well as wisdom through the problem-solving process. By discussing how to realize the harmonious balance between presupposition and generation,this article aims to find the best instructions durinz the teaching, nrncess.
