系统论的反馈原理指出:任何系统,只有通过反馈信息才能实现控制,没有反馈信息的系统要实现控制是不可能的。课堂教学过程是教与学之间的信息传递和反馈的控制过程,即教师围绕着某一教学目标和要求进行的动态系统。在这个系统中,教师按一定的计划和层次向学生输出一定量的信息,学生接受信息后产生的结果再反馈给教师,教师通过分析、判断,对信息的再输出进行调控,以便变换教法,调整教学过程,使得教与学更加和谐地发展。然而,当前人们普遍对信息反馈不够重视,有相当多的数学课,信息反馈不到位或者没有很好地加以利用。
Systematic feedback principle points out: Any system, can only realize the control through the feedback information, the system without feedback information wants to realize the control is impossible. The classroom teaching process is the control process of information transmission and feedback between teaching and learning, that is, the dynamic system of teachers around a certain teaching goal and requirement. In this system, the teacher outputs a certain amount of information to the students according to a certain plan and level. After the students receive the information, the result is fed back to the teacher. The teacher adjusts and regulates the re-output of the information in order to change the teaching method , Adjust the teaching process, making teaching and learning more harmonious development. However, people generally do not pay enough attention to information feedback, have a lot of math classes, and information feedback is not in place or not well utilized.
