The emphasis of this paper is on the derivation of design principles from qualitative analysis of student reflections based on their participation in authentic, collaborative and technology-mediated activities. This paper reports on the initial phases of a design-based research project at a comprehensive university in South Africa where the authentic nature of the activities contributed to the depth of student reflections and ultimately led to meaningful design principles based entirely on the experiences of students. Students' reflective reports were analysed for their content using simple inductive coding techniques leading to the identification of themes and the derivation of design principles from further refinement of these themes. These design principles, therefore, have their origins in the specific theories underpinning the learning activities that were used in the teaching and learning process, and contribute once again in an innovative way to this same body of knowledge. This theory-driven praxis thus makes a contribution to both educational theory and teaching practice which is applicable across a variety of contexts and sectors worldwide. More importantly, this can be seen as meaningful research that is socially responsible, with a high theoretical and practical value, and of relevance to a wider international audience.
