课堂教学虽是教学系统中的一个要素(一个必不可少的重要因素),但就课堂而言,又是一个相对独立的整体。教师、学生、教材及教学条件、教学方法均为这一整体中的要素。它们同处于课堂教学这一系统中,即使把一个个的备课过程、讲课过程、听课过程、作业过程……机械地叠加起来,或随意地捏在一起,也不会产生课堂教学的高效应,课堂教学中的这种性质和效应,就在于系统中诸因素之间的内在的有机联系。挖掘出这种内在联系,并利用其进行优化组合,就能提高课 Classroom teaching is an essential element of the teaching system (an indispensable factor), but in the classroom, it is a relatively independent whole. Teachers, students, teaching materials and teaching conditions, teaching methods are the elements of this whole. They are in the same classroom teaching system, even if the preparation process, lectures, lectures, work processes ... ... mechanically superimposed, or randomly pinch together, it will not produce high efficiency in classroom teaching, This nature and effect of classroom teaching lies in the inherent organic connection among the factors in the system. Dig out this kind of internal relations, and use it to optimize the combination, you can improve the class
