Commentators

The task of conductors is to coordinate students in a macro way, while the job of
directors is to grasp the situation in a micro way. It is the task of commentators to
evaluate all the teaching activities in a summative way. They should evaluate the
advantages and shortcomings comprehensively during students’ oral expression to
make students more confident. They should let students understand their shortcomings
and provide guidance for them so that the same mistakes can be avoided.
In order to be more objective and reasonable, commentators should take part in
different activities to discover problems and solve them in time. To be a good
commentator, teachers should follow one principle. That is, they should not point
out the errors during the process of students’ expression, which will interrupt their
thinking and discourage their confidence. For some simple slip of the tongue,
teachers should pay less attention, while for some big mistakes especially those in
thinking and being made easily by the majority of students, teachers should point
them out in front of all students. In this way, students will pay more attention to the
problem. Besides summarizing the past experience, commentators should also
predict the future and provide guidance for students. Teachers should know the
employment situation in the industry and the trend of future development of oral
English talents as well as how to win in the future employment competition. They
should guide and develop their students according to the situations above.
