每次学生学到神经调节的时候,都会觉得关于在神经纤维上装置电流表,不断变化刺激部位,从而判断指针偏转的问题特别难。为什么在整个反射弧的某两点接上电流表之后,有的时候偏转一次而有的时候却偏转两次?为什么有的时候先向左而有的时候又先向右呢?学生不断发问的同时,我一边解决他们的问题,一边在考虑:有没有什么好办法能有效地解决学生的困难呢?并且最好 Each time a student learns about neuromodulation, he or she will find it particularly difficult to determine the deflection of a pointer as it is equipped with an ammeter on a nerve fiber and constantly changing the stimulation site. Why after some point in the entire reflective arc connected ammeter, sometimes deflected once but sometimes deflected twice? Why sometimes the first left and sometimes the first right? Students constantly asking As I tackle their problems, I’m thinking about the following: Is there any good way to effectively deal with student difficulties?
