Abstract: The ‘Phase 1 Prac Project’ (P1PP) and ‘Phase 2 Prac Project’ (P2PP) were initiatives developed as part of the BEST Network (www.best.edu.au) to systematically develop online support materials for biomedical science practicals held in Phase 1 (Years 1 and 2) and Phase 2 (Years 3 and 4) Medicine. Systematic production of academic, peer-evaluated online practical elements (OPEs), focussed on learning bottlenecks and threshold concepts in these practicals, were produced using the Smart Sparrow Adaptive eLearning Platform (AeLP). The project delivered 42 re-useable, editable OPEs, tested by students and refined using available analytical data and academic peer review to ensure student satisfaction and content quality. These OPEs will benefit future blended learning activities offered to biomedical university students globally.
