I am an administrator and an instructor so I understand the challenges of dealing with some students, but what the students need is for the instructors/adminstrative staff to understand how important their demeanor -- their body language and tone of voice are in managing a positive, productive class.
It is not enough to do a great job teaching. The students have to want to attend a class and some teachers can be so intimidating that the confidence of the student is eroded.
The student then does not wish to attend a class like that and then finally, the student may decide to withdraw.
These issues have been discussed as a result of student evaluations of staff members. There has been some improvement, but not enough.
