数学课堂教学过程实际上是师生输出和接受信息的过程．教学过程的优劣与信息传输的效率等密切相关，而传输的效率则取决于教师能否根据学生反应，优选措施来调控知识信息输出的数量、速度和密度，使师生双方处于相互适应、协调的共振状态，即对传输过程实施有效的控制．教师各 The mathematics classroom teaching process is actually the process of teachers and students exporting and receiving information. The pros and cons of the teaching process are closely related to the efficiency of information transmission, and the efficiency of transmission depends on whether the teacher can adjust the quantity, speed, and density of knowledge information output according to student responses and optimization measures, so that both teachers and students can adapt to each other. Coordinated resonance state, ie effective control of the transmission process. Teachers
