Many colleges and universities have adopted the use of student ratings
of instruction as one (often the most influential) measure of instruc
tional effectiveness. In this article, the authors present evidence th
at although effective instruction may be multidimensional, student rat
ings of instruction measure general instructional skill, which is a co
mposite of three subskills: delivering instruction, facilitating inter
actions, and evaluating student learning. The authors subsequently rep
ort the results of a metaanalysis of the multisection validity studies
that indicate that student ratings are moderately valid; however, adm
inistrative, instructor, and course characteristics influence student
ratings of instruction.
