反馈,是控制论的重要概念,是指操作物按操作中心的指令活动,其本身的状态,又作为一种新的信号返回,使操作中心对操作施以调节。控制论认为,任何操作只有通过反馈才能进行得更确切,才能实施更有效的控制,从而达到预期的操作目的,这一原理具有普遍意义。对于生物课堂教学,教师既要把知识信息有计划地传输给学生,还应随时接收来自学生的反馈信息,由此对自己的信息传输进行调节,对学生的信息接收实施调控;学生不仅接收教师传输来的信息,而且输出反应信息,再接收来自教师和学生的反馈信息,一边加工贮存,一边调节自己的后续学习,其基本模式是:
Feedback is an important concept of cybernetics. It refers to the operation of the operator according to the instruction of the operation center, its own state, and return as a new signal, so that the operation center can adjust the operation. Cybernetics believes that any operation can only be performed more accurately through feedback, and more effective control can be implemented to achieve the intended purpose of operation. This principle has universal significance. For biological classroom teaching, teachers must transfer knowledge information to students in a planned way, and they should also receive feedback from students at any time, thus regulating their own information transmission and regulating students’ information reception. Students not only receive teachers. The transmitted information, and the output of response information, and then receive feedback from teachers and students, while processing and storage, while adjusting their follow-up learning, the basic model is:
