化学教学过程,也是信息反馈过程。自觉地、科学地收集、分析、运用学生反馈信息,是提高化学教学效率,大面积提高教学质量的重要途径。现从信息论、控制论的角度作初步的探讨。教学效率跟信息反馈效率一般指日常工作中所消耗的劳动量与所获得的劳动效果的比率。教学的劳动量通常用时间表示。所以,教学效率可用如下公式表示:
Chemistry teaching process is also information feedback process. Conscientiously and scientifically collecting, analyzing, and using student feedback information is an important way to improve the efficiency of chemistry teaching and greatly improve the quality of teaching. From the perspective of information theory and cybernetics, we will make a preliminary discussion. The efficiency of teaching and information feedback generally refers to the ratio of the amount of labor consumed in the daily work and the labor effect obtained. The amount of labor taught is usually expressed in terms of time. Therefore, teaching efficiency can be expressed by the following formula:
