The objective of this paper is to describe the design case of a web-based system that aims to facilitate the collective reflective practice of a learning group in an academic setting. The technical infrastructure of the system is fully implemented using free web services, which requires minimum technical knowledge or expertise. A key technical component of the proposed system is a web mash-up hub node that filters and aggregates the relevant posts coming from the participating members' blogs. The overall design process, including the theoretical inspiration, the context, and the implementation, is presented in full detail. This design case can be utilized to inform and inspire other educators or reflective practitioners to design similar systems.
