Learning Object Evaluation: Computer-Mediated Collaboration and Inter-Rater Reliacbility
International Journal of Computers and Applications, (2003)
Abstract
Learning objects offer increased ability to share learning resources so that system-wide production costs can be reduced. But how can users select from a set of similar learning objects in a repository and be assured of quality? This article reviews recent developments in the establishment of learning object repositories and metadata standards, and presents a formative reliability analysis of an online, collaborative method for evaluating quality of learning objects. The method uses a 10-item Learning Object Review Instrument (LORI) within a Convergent Participation evaluation model that brings together instructional designers, media developers, and instructors. The inter-rater reliability analysis of 12 raters evaluating eight learning objects identified specific items in LORI that require further development. Overall, the collaborative process substantially increased the reliability and validity of aggregate learning object ratings. The study concludes with specific recommendations including changes to LORI items, a rater training process, and requirements for selecting an evaluation team.
