有些老师上课常常因想多讲一点,拖了课,或因教学量的控制不当,不能及时下课,从而影响了学生的课间休息。学生课间休息的时间得不到保证,从心理学的角度来说,是很不科学的。学生掌握知识的过程是通过神经活动过程来完成的。而神经活动又包括兴奋过程即抑制过程,这两者是密切地联系在一起的,在一定的条件下可以相互转化。这就是说,兴奋过程可以转化为抑制过程,抑制过程可以转化为兴奋过程。刺激物过于强烈或者持续作用的时间过久,超过了神经细胞兴奋的限度,兴奋过程就会转为抑制过程。从生理保护的角度看,课间休息也是人体神经 Some teachers often want to talk more about class, drag the class, or due to improper teaching of the amount of control, can not be timely get out of class, thus affecting the students' rest. Students can not rest during recess time, from a psychological point of view, it is unscientific. Students grasp the process of knowledge through the process of neural activity to complete. The neural activity, including the excitement process that is the suppression process, the two are closely linked, under certain conditions can be transformed into each other. This means that the excitement process can be transformed into a suppression process, and the suppression process can be transformed into an excitement process. Excessive stimulus or sustained effect of too long, beyond the limits of nerve cell excitement, the excitement process will be converted to inhibit the process. From a physiological protection point of view, recess is also a human nerve
