  23. Teaching philosophy • 李尚志（中科大前数学系系主任）说： • 丁石孙教授讲的《交换代数》课给我留下特别深刻的印象。他讲课从来不一步一步讲证明的细节，而着重讲整体思路和想法，细节让我们自己课后去补充出来。他说：讲细节谁都听不懂、跟不上。如果你上来讲一个中学的平面几何证明题，你预先经过反复思考已经熟悉了，我预先没有思想准备，听的时候就肯定跟不上你的每一步。 • 他这种讲课方式对我现在的讲课影响也很大。我发现，凡是科研搞得好、讲课也讲得好的老师，讲课风格可能各不相同，但一个共同点都是强调主体思路，分得清哪是主干哪是枝叶。因为他们搞科研的时候就是先大体上构思了总体框架、然后再添枝加叶加以实现和完善的。 • 课堂讲授的内容与教材里的内容是互补的，尽量不是重复的！因此，课后一定要阅读指定的材料。 USTC-21000201-OPERATING SYSTEMS; FALL 2014; INSTRUCTOR: CHI ZHANG
