近年来,广大数学教师都在研究如何优化教学过程,大面积提高教学质量.归纳起来一句话:不靠加班加点,不靠超负荷的布置作业,向40分钟要质量.在这里,如何及时而又准确地把握反馈原则是个十分重要的问题.教学过程是学生在教师的指导下,由不知到知.由知之较少到知之较多的认识过程:说得明确些,教学过程是师生双方信息交流的可控的双边活动:如果用系统论的观点来分析,教学过程又是一个多层次、多方面、多矛盾的大系统.严格说来,没有反馈,就谈不上控制;没
In recent years, the majority of mathematics teachers are studying how to optimize the teaching process, large-scale improvement of teaching quality.To summarize the sentence: do not rely on overtime, not rely on the layout of the work overload, 40 minutes to the quality here how timely And accurately grasp the principle of feedback is a very important issue.Teaching process is under the guidance of the teacher, the students from ignorant to know by less known to know more cognitive process: put it more clearly, the teaching process is both teachers and students Controllable Bilateral Activities for the Exchange of Information: The teaching process is a multi-level, multi-faceted and contradictory system if analyzed systematically. Strictly speaking, without feedback, there is no control. No
