We propose a model for Internet learning grounded in a theoretical analysis of transfer and embodied within a general tool called STELLAR (Socio-Technical Environment for Learning and Learning-Activity Research). STELLAR supports creation and management of online courses that systematically integrate collaborative design with study of text and video. The objective of STELLAR is to help learners develop "meshed" cognitive representations that support transfer of course knowledge to professional practice. Using STELLAR, we created experimental online courses in the learning sciences1 for pre-service teachers. Our research produced substantial evidence supporting our approach and a body of empirically tested online materials and collaborative activities for teacher education.
