从“三论”(信息论、控制论、系统论)的观点看,教学,是一个由教授过程和学习过程之间的教学信息传递和反馈现象始终存在而有机地联系起来的完整的系统。课堂教学应以学生获得信息量最大及教师了解学生反馈最及时、调控最得力为最佳。通过学习,现在不少老师认识到注入式的弊端,初步地把单向传递、由点到面的教学结构改为多向传递、立体交叉式的教学结构。这的确是个了不起的进步。但由于不善于调控,理解又有片面,因
From the point of view of the “three theories” (information theory, cybernetics, and system theory), teaching is a complete system that is always connected and organically linked by the transmission and feedback of teaching information between the teaching process and the learning process. Classroom teaching should be based on the maximum amount of information a student can obtain and the teacher’s understanding of student feedback is the most timely and the most effective in controlling. Through learning, many teachers now recognize the drawbacks of injection, and initially change the one-way transmission and point-to-face teaching structure into a multi-directional, three-dimensional, intersecting teaching structure. This is indeed a remarkable progress. However, due to poor control and understanding, there is one-sided understanding.
