Nowadays, college students pay more and more attention to
optional courses because they consider them a good way to enrich their
knowledge. Recently, some universities have begun allowing students to
choose the teachers of some optional lectures.

     When it comes to choosing teachers, students often have the
following considerations. First, they are convinced that teachers
should be knowledgeable and should be experts in the fields they
teach. Second, teachers should be responsible and great importance
should be attached to adequate preparation for the courses. Only by
meeting these two requirements will teachers be the best choice for
students.

     Allowing students to choose teachers will give rise to both
benefits and problems. The advantages include the fact that competent
and respectable teachers will stand out and students will be more
willing to take optional courses. However, schools may give too much
power to students and this may result in teacher's complaints and
disorder in teaching programs. So schools should weigh both the
advantages and the disadvantages, and try to satisfy the students'
needs as well as arrange the lecturers in a sensible way.
