一、反馈的概念及在教学训练中的作用反馈一词出自控制论。控制论创始人维纳认为:反馈是输出信息的一部分,而这部分的输出信息,又返回到输入信息中去,通过伺服机构的调整,使再次输出更为精确。参见图一。由图一可见,信息从输入到输出,再从输出(部分信息)反馈到输入,使信息的传送形成一个持续不断的闭环。伺服机构实际上是获得了两种信息,一种是新的输入信息,另一种
First, the concept of feedback and its role in teaching and training The word feedback comes from cybernetics. Wiener, the founder of cybernetics, believes that feedback is part of the output information, and that the output information of this part is returned to the input information. Through servo adjustments, the output is more accurate. See Figure 1. From Figure 1, we can see that the information is input from the input to the output, and then the output (part of the information) is fed back to the input so that the transmission of information forms a continuous closed loop. Actually, the servo system has obtained two kinds of information. One is new input information and the other is
