Group Assessment of Learning Management Systems

In our earlier works (Srdjevic et al., 2012 ; Pipan et al., 2013) it was shown that if there are several available Learning Management Systems (LMS), a multi-criteria method AHP (Analytic Hierarchy Process) or DEXi multi-criteria model can be used to support decision maker in selecting the most suitable system. The decision making results of the application obtained by the individual expert using above mentioned methods have been already compared and published in Pipan et al. (2013). Here we extend an approach to group assessment. Three experts from the Technology Enhanced Learning (TEL) domain evaluated the same three LMSs against five typical criteria and their individual decisions were aggregated geometrically to obtain the final group decision. Unbiased weighting of decision makers is assumed and the consistency indicators were checked for each decision maker to justify associated equal weights and preserve that the final decision was correctly derived.
