信息论是研究信息的计量、传递、变换、贮存和使用规律的科学。就教学而言,教学过程是教和学的各种信息的综合反映,是信息输入、传输、处理、反馈和转化的过程。因此,运用信息传递规律指导物理教学,对达成教学目标,提高课堂教学的有效性都能发挥积极的作用。一、把握教学关键,准确输出信息按照信息论原理,信息是生命系统、机器系统等在适应外部世界、同外部世界进行交换的过程中形成的特有的物质运动形式。在教学过程中,要在教师、教材、学生及外部环境构成的系统中正确交换信息,信
Information theory is a science that studies the law of measurement, transmission, transformation, storage and use of information. In terms of teaching, the teaching process is a comprehensive reflection of all kinds of information in teaching and learning. It is a process of information input, transmission, processing, feedback and transformation. Therefore, using the law of information transmission to guide physics teaching can play an active role in reaching teaching objectives and improving the effectiveness of classroom teaching. I. Grasp the Key to Teaching and Exporting Information Accurately According to the theory of information theory, information is a unique form of material movement formed by living systems and machine systems in the process of adapting to the outside world and exchanging with the outside world. In the teaching process, the correct exchange of information in the system of teachers, teaching materials, students and the external environment, the letter
