由于中职学校的学生参差不齐,特点各异,加大了班主任的工作压力和管理难度。而且这些学生大多呈现出对专业课相对重视,对公共课却较为轻视的特点,更无形地加大了任课老师的课堂压力,因此需对课堂进行分层次教学。 Due to the unevenness of the students in secondary vocational schools, different characteristics, increase the class teacher's work pressure and management difficulty.

Therefore, it is necessary to teach the classrooms in different levels.
