Conclusion
• Mashup Recommender– helps to create own PLE suitable for SRL– based on a template / learning ontology approach– all components have open interfaces – can be used by other tools– overall evaluation result quite positive
• Next steps– recommendations based on usage data– recommendations based on learning goals (widgets can be
associated with domain concepts)
