Designing Learning Design Systems: Architecture and Integration Issues

This session, led by Scott Wilson, focuses on the architecture of learning design systems. It aims to address key challenges in designing both pre-runtime and runtime architectures for these systems. Important topics include integrating learning design with informal learning and social activities, managing learning activities and communication between systems, and monitoring and intervention strategies. Attendees are encouraged to discuss their ideas and identify problems, gaps, and solutions related to learning design systems and their integration with existing tools and workflows.

  3. Task • Design the runtime and pre-runtime architecture for learning design systems • Identify the major issues and unknowns

  4. Source materials • The “Dagstuhl diagram” • The “VLE of the Future” • CCSI/SLeD • ReST Workflow System Model • LAMS Tool API

  5. Different worlds? • How can we integrate LD with informal learning, social activity and work? • Well, I don’t think they’re going to learn to speak LD! • I’ve got a few ideas I’d like to discuss, and to hear yours too

  6. Architectural problems • How does an LD system manage learning activities at runtime? • How does an LD systems communicate the activity states with client systems, and receive and process workflow events?

  7. ReST Workflow

  8. SOAP Workflow

  9. SOAP Workflow - WSRF /Grid style

  10. CCSI: SOAP-ish server-side Management of LDs CCSI model

  11. ReST Workflow (Activity-flavoured)

  12. Questions… • How tightly does LD need to manage its clients? • What is the role of synchronous services? How should they be modeled? • Does LD need to be push/pub-sub as well as, or instead of, request-response? • How do we fit tool integration into the picture? • What is the impact of security concerns? • How to specify tools/services in LD itself?

  13. Monitoring and intervention • Where and how does monitoring fit? • Where and how can intervention occur?

  14. Now its your turn! • Using these models as a basis: • Identify the problems with the models • Identify solutions • Identify gaps • Define the services and components needed • Decide the preferred protocol type(s) s(e.g. HTTP, XMPP, RMI) and protocol style(s) (e.g. RPC/SOAP, REST, pub-sub) • Come up with alternatives that may be better
