物理是一门以实验为基础的学科,它的地位决定了每周课时少,有时几个班的物理课时加起来才能与一个班的语文课工作量持平,加之物理实验仪器大多笨重,做一个演示实验有时要搬几次仪器,所以有些实验教师为了应付上级检查,填一下《演示实验通知单》,将仪器搬进办公室后就再也不搬进教室,在教室里就 Physics is an experiment-based discipline, its status determines the weekly class hours less, and sometimes several classes of physical lessons together to be able to work with a class of Chinese class workload, coupled with physical experiment equipment mostly bulky, to do a Demonstration experiment sometimes to move the instrument several times, so some experimental teachers in order to cope with the higher inspection, fill in the “demo experiment notice”, the instrument moved into the office will never move into the classroom, in the classroom
