The first component of the model brings together some of the aspects that can be studied in the evaluation of a CSCL system. We have grouped them into three different facets.

The third facet, the Method, refers to the sequence of steps that lead the evaluation process, involving reasoning, observations, data collection, data processing, analysis and interpretation. The sort of evaluands that can be evaluated in these special scenarios differ so much; because of this, the model proposes many different data gathering techniques, not only naturalistic inquiry or qualitative research ones, with the aim of becoming an umbrella model where different traditions and ways of evaluation would coexist. The model encourages the use of mixed data gathering techniques as well as a variety of informants, in order to provide multiple perspectives to enrich the evaluation process. The model includes five different evaluation approaches from which an evaluation could be conducted; Case Study methods, Action Research methods, Usability methods, Human Computer Interaction methods and Interaction Analysis methods. In this sense the model proposes a profuse set of data gathering techniques like observations, interviews, expert reviews, costing techniques, heuristics, cognitive walkthroughs, social network analysis or feature inspections.
