Title: Applying the many-facet rasch model to evaluate powerpoint presentation performance in higher education
Authors: Baştürk, Ramazan
Abstract: This study investigated the usefulness of the many-facet Rasch model (MFRM) in evaluating the quality of performance related to PowerPoint presentations in higher education. The Rasch Model utilizes item response theory stating that the probability of a correct response to a test item/task depends largely on a single parameter, the ability of the person. MFRM extends this one-parameter model to other facets of task difficulty, for example, rater severity, rating scale format, task difficulty levels. This paper specifically investigated presentation ability in terms of items/task difficulty and rater severity/leniency. First-year science education students prepared and used the PowerPoint presentation software program during the autumn semester of the 2005-2006 school year in the 'Introduction to the Teaching Profession' course. The students were divided into six sub-groups and each sub-group was given an instructional topic, based on the content and objectives of the course, to prepare a PowerPoint presentation. Seven judges, including the course instructor, evaluated each group's PowerPoint presentation performance using 'A+ PowerPoint Rubric'. The results of this study show that the MFRM technique is a powerful tool for handling polytomous data in performance and peer assessment in higher education. © 2008 Taylor & Francis.
