笔者曾于上学期听了两位新教师的课。一位新教师了解到这个班的纪律较差，于是刚上课就宣布：“在这节课结束前，我们要评一个红花少年组，下面老师就看哪个组的同学最遵守纪律。”此话很见成效，大多数学生在上课时都有良好表现。下课前，我正猜测这位老师如何开展评比，谁知? I had heard two new teachers in class last semester. A new teacher, aware of the poor discipline of the class, immediately announced at the beginning of the class: “Before the class ended, we would like to comment on a group of safflower boys. The teacher below will see which group of classmates is the most disciplined.” Very effective words, most students in class have a good performance. Before get out of class, I was guessing how the teacher conducted appraisals, who knows?
