在新的课程改革背景下,如何让新理念走进课堂,如何让新理念渗透于教学,从而有效地进行数学教学,是每位数学教师必须面对的问题。所谓有效性教学最关键的是要激发学生主动学习自主学习,否则,不管你怎么教学也是无效或低效的。数学教学不光涉及到数学知识的传递,而且关系到数学思想、数学形象、数学态度、数学情感、数学技能等诸多方面。如 In the context of the new curriculum reform, how to let new ideas into the classroom, how to infiltrate the new ideas in teaching, so that mathematics teaching is effective, every mathematics teacher must face the problem. The so-called effectiveness of teaching the most crucial is to stimulate students to actively study independent learning, otherwise, no matter how you teach is invalid or inefficient. Mathematics teaching involves not only the transfer of mathematical knowledge, but also many aspects such as mathematical thought, mathematical image, mathematical attitude, mathematical emotion, mathematical skills and so on.
