在控制论看来,教师和学生都是教学这一可控系统的控制者和被控制者,他们之间是互相控制和被控制的关系,这一系统中的教学内容和学习反馈作为信息流在各要素之间传递,从而达到学习最优化的目的.所谓物理课堂教学的最优控制,就是师生耗费最合理的课堂教学时间取得尽可能大的教学成效.从当下我省的教育现状来看,重分数、轻等级的问题日趋严重,为了提高分数,很多学校甚至提出了“血拼语数外”的口号,作为只计等级的物理学科则日趋边缘化.因此,如何用最少的时
In cybernetics, both teachers and students are the controllers and controllers of the controllable system of instruction. They control each other and are controlled. The teaching contents and learning feedback in this system are used as the information flow The transfer between the various elements, so as to achieve the purpose of learning optimization.The so-called optimal control of physical classroom teaching, teachers and students spend the most reasonable classroom teaching time to achieve the greatest possible teaching effectiveness from the current situation in our province’s education In order to raise the scores, many schools even put forward the slogan of “marrying a few words”, and the physics as a mere grade is getting more and more marginalized. Therefore, how to use the least When
