Why Student Ratings?
The data most widely used in the evaluation of college teaching come
from student ratings. These data can be a blessing or a bane for the
instructor, depending on how they are collected, interpreted, and used.
What's the real story on ratings?
By Michael Theall, University of
Illinois at Springfield
Data from student ratings can provide valuable information on teaching
effectiveness for students, teachers, and administrators. But these ratings
are, too often, misinterpreted, misused, or used to support the
interpreter's biases and beliefs.
For example, one of the first issues in evaluation is to determine the
purpose for it. When we gather information to review, explore, or improve,
we use the term formative evaluation. When our purpose is to make
decisions about merit, promotion, or tenure, then we use the term summative
evaluation.
It may seem obvious that summative evaluation requires more technical
rigor and a wider array of data than formative evaluation, but the
unfortunate reality is that summative decisions about teaching are often
made on the basis of student ratings data alone. The result: a great deal of
suspicion, anxiety, and even hostility toward ratings by faculty, and
deservedly so. But it doesn't have to be this way.
Faculty and adminstrators, working together, can make better decisions
about the teaching effectiveness of faculty if they are well-informed about
the extensive research on student ratings and know how to use these tools in
effective evaluative processes.
In the following pages, I hope to offer the
reader some insight into effective interpretation and use of student ratings
and to suggest ways that student ratings can be used by administrators and
faculty as part of an overall plan to improve teaching and learning.
