Adaptation languages for learning: the CAM meta-model

Outline
• Why personalisation?• Adaptive Hypermedia (AH)• Course creation (authoring) by non-technical
users• Proposed solution• Conclusions and further work

Why personalisation?
• Students benefit from personalised attention
• Teachers are unable to provide this for every student
• Systems that can offer this could improve the learning outcomes
![Page 4: Maurice Hendrix, Alexandra I. Cristea A3H @ EC-TEL 2009 {maurice, acristea}@dcs.warwick.ac.uk Adaptation languages for learning: the CAM meta-model.](https://reader035.fdocuments.in/reader035/viewer/2022062619/55160e2d550346a2308b51af/html5/thumbnails/4.jpg)
Adaptive Hypermedia
• Hypermedia • Set of nodes and links, e.g. web page
• Adaptive• What to adapt : presentation,
navigation• What to adapt to : user (e.g.
preference, knowledge), environment (e.g. device, connection)
• Can deliver personalised attention
• Has potential to improve learning outcome

Course creation (authoring) by non-technical users
• AH course creation is more complex, involves writing adaptation strategy
• Trade off between expressivity and ease of use by teachers crucial for success of AH
• Re-usability often limited

Solutions up to now
• System specific (XML) formats
• Graph based e.g. AHA! Graph author, without separation into layers (conceptual domain, adaptation strategy, course)
• Layers based e.g. MOT with LAG. But based on tree structure.

Proposed solution:Conceptual Adaptation Model

Implications for Adaptation Languages
• Visual language for DM, (CRT) and CAM
• XML language for internal repr. DM, CRT, CAM
• Export language package: CAM

XML language• Common header, with name, description,
creation date and date last updated
• DM: IMS-VDEX based
• CRT: UM variables in use, constraints on combining CRTs, adaptive behaviour in adaptation language
• CAM: contains DM and CRT and instantiation or CRTs with Concepts from DM

Conclusions and further work
• Presented a novel model and tool for authoring of AH that could help realise potential for learning
• The evaluation to gather usability and user acceptance data via a standard SUS usability test and a more extensive formative evaluation
