Calibrating questionnaires by psychometric analysis to evaluate knowledge

Abstract

The experience achieved using the tool “Questionnaires,” available inside the Virtual Campus of an architectural engineering school in northeast Spain, is presented. “Questionnaires” is a mechanism/tool adequate and simple to evaluate the knowledge level achieved by students. This work shows and identifies the control indices of adaptation for questionnaires, such as the Facility Index, the standard deviation, the Discrimination Index, and the Discrimination Coefficient. From these parameters, educational performance is inferred, identified, and predicted. The conclusions of this work will allow the modification of deficient knowledge-evaluation practices and the identification of needs for specific groups or for students with particular requirements, thus making it feasible to apply these parameters with a guarantee of success in similar evaluation processes.
