提高教学质量,培养高素质的合格人才,是每住教师孜孜以求的目标。本文作者在十几年的机械课教学实践中,针对学生主动性、积极性不高的现状,积极在教学方法上加以改进。一改过去被动答疑方式为主动质疑方式,不仅给学生一定的压力,促其温故而知新,而且又能教学相长,拓宽了教师备课的深度和广度。 Improve the quality of teaching, training qualified personnel of high quality, every stay is the goal of teachers. In the more than ten years of mechanical class teaching practice, the author actively improves his teaching methods according to the students’ initiative and enthusiasm. Changing the passive answering mode in the past is an active way of questioning. It not only gives students some pressure and urges them to learn new things but also enables them to teach and grow. This broadens the depth and breadth of teacher preparation.
