“两馈”是指数学教学中的“反馈”和“前馈”。所谓“反馈”,是指信息输出者把变换了的信息作用于接收者后产生结果再接收回来,并以此对再输出的信息发生影响的过程。没有反馈,教学过程就只能处于盲目、混乱的状态之中。在小学数学教学中运用反馈教学,其目的是为“矫正”,变错 “Two feeds” refers to “feedback” and “feedforward” in mathematics teaching. The so-called “feedback” refers to the information output of the transformed information on the receiver to produce the result and then received back, and then re-output of the information affecting the process. Without feedback, the teaching process can only be in a blind, chaotic state. The use of feedback teaching in elementary mathematics teaching aims to “correct” and change mistakes
