a web-based group decision support system for the selection and evaluation of educational multimedia
Multimedia is now a relatively mature field, having advanced over more than two decades. The combination of text, images, videos, animations, etc. in both presentational and conversational form is now a standard part of most computer applications, web-based and stand-alone alike. As such, Educational Multimedia (EMM) can be a great tool to improve teaching and learning. However, EMM selection and evaluation for higher education is a complex and interdisciplinary problem characterised by uncertainty, dynamics, explicit and implicit knowledge and constraints, and involvement of different stakeholders. In this work, we use a domain-based web oriented Group Decision Support System (GDSS) for the selection and continuous evaluation of EMM for educational providers. We investigate the viability of developing and validating a web-based GDSS, integrated with knowledge management (KM) and instructional design, as a support tool to overcome the difficulties in the selection and evaluation of EMM. The proposed solution manages and supports the six phases of planning, intelligence, design, choice, implementation, and evaluation. In addition to design and implementation, performance evaluation is also presented using data collected from experts, instructors, and EMM producers. The results reveal that the proposed solution can successfully help educational consumers in selecting and evaluating EMM.
