Applying the Many-Facet Rasch Model to Evaluate PowerPoint Presentation Performance in Higher Education
Basturk, Ramazan
Assessment & Evaluation in Higher Education, v33 n4 p431-444 Aug 2008
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. (Contains 1 figure and 4 tables.)
