Testing the Validity of the Post and Vote Model of Web-Based Peer Assessment

Abstract

Two tests of validity were conducted with undergraduate education students on a method of online peer assessment called post and vote. Validity was determined by calculating a Pearson product-moment correlation and corresponding coefficient of determination that compared the average grade assigned by the pre-service teachers with the grade assigned independently by the course instructor. Results of both studies showed that post and vote Web-based peer assessment was valid with these groups, and generalizable to undergraduate classes engaged in similar tasks.
