In light of the expanded student recruitment and increased difficulty in management, the focus should be shifted in the following aspects: from macro-control of teaching quality to micro-control, from end quality to process quality, from teaching to learning, from unclosed-in control to closed-in control, and from irregular control to routine control.
当前,在招生规模扩大,管理难度增加的情况下,应实现教学质量监控由注重宏观向关注微观转变,由抓终末质量向抓过程质量转变,由重视教师的教向重视学生的学转变,由监控不封闭向监控封闭转变,由不定期监控向常规监控转变,只有这样才能收到良好的监控效果,达到稳定和提高教学质量的目的。
