Content Validity and the Uses of Student Ratings.
Thorndike, Robert M.; Waldram, Carol A.
The validity of a rating instrument depends not only upon the content of the instrument and the purposes the instrument is to serve, but also upon its relationships to criteria external to the instrument. Formative and summative evaluation require two distinct types of instruments which yield different types of information. The problem that remains in the development of formative rating devices is a definition and enumeration of the domain of teaching behaviors. A solution to this problem possibly would be different for various subject areas and teaching styles. Careful sampling of this domain may require a set of rating devices which are hierachically arranged. Current rating instruments represent a step toward the development of broad-band devices, which could be used at the highest level of the hierarchy to identify problem areas, and may also be useful for summative evaluation purposes. Evaluation instruments yield information that is reliable and logically expected to be related to quality of teaching performance. What is lacking is evidence relating ratings to important educational outcomes. (Author/RC)
