This article discusses the implementation of an ePortfolio-based learning environment with Bachelor of Education students. The intention was for the platform to be an agency for the development of reflection. The environment scaffolded reflection through (1) exemplars of good practice, (2) the opportunity for discussions and (3) activities to support the development of reflection. There were issues within the research around the introduction of the platform at the particular stage of the students' degrees but the environment was successful in the provision of a teaching and learning platform. The findings provided design principles for a model to guide the development of similar learning environments including (1) the need for the ePortfolio platform to be embedded across the degree programme with (2) regular tasks for the students to complete that (3) have a clear purpose that the students are aware of and (4) utilise interaction patterns that mimic the structures of social media.
