During the apprentice period in primary schools, the most frequent activities that teachers engage in is sitting a class. The teachers who give a lesson include both probationary teachers and mature ones. Their differences have been discovered by the author. Classroom performance remarks are one of their differences. Such remarksmainly refer to verbal comments on various performances of students, such as their answers and so on. Due to the restrictions of their physical and mental developments, pupils are usually less concerned about their behavioral habits, but they are very keep about teachers' judgments on their behaviors. They like to regards teachers' praises and compliments as the result of their active actions. The classroom comments from probationary and mature teachers would be the focus of my research. I will probe the verbal differences between the two groups and the key points for new teachers to grasp. In this way, probationary teachers like me can be better informed and inspired. 仅供参考,欢迎指正
