Classroom public speaking assessment: Reliability and validity of selected evaluation instruments

Abstract

In this article, the researchers investigate reliability and validity of a variety of speech evaluation instruments used in public speaking classes. Raters from diverse backgrounds and experience evaluated videotaped speeches using various evaluation forms. Results indicate student speeches can be evaluated reliably and validly using any of a number of different evaluation forms that address the fundamental speech constructs of content and delivery. In addition, lack of extensive rater training and experience do not appear to have a major negative impact on the evaluation process.
