数学教学中的反馈控制民勤县五中姜千基纵观数学教学的过程，如果以教学输入信息为参照坐标，那么教学反馈信息相对于输入信息存在着不同的位置，存在着明显的时间差，由此我们可将教学反馈划分为三类：超前反馈、同步反馈与滞后反馈。本文试图对如何利用反馈而得的信息来...
The feedback control in mathematics teaching Minqin County Wuzhong Jiang Qianji Looking through the process of teaching mathematics, if the input information for teaching is used as the reference coordinate, then there is a different position of teaching feedback information relative to the input information, and there is a significant time difference. We can divide teaching feedback into three categories: advanced feedback, synchronous feedback, and delayed feedback. This article attempts to obtain information on how to use feedback...
