NIntroduction
Adaptation: a definition
Adaptation is about creating a learner experience that purposely adjusts to various conditions (personal characteristics, pedagogical knowledge, the learner interactions, the outcome of the actual learning processes) over a period of time with the intention to increase pre-defined success criteria (effectiveness of e-learning: score, time, economical costs, user satisfaction)

NIntroduction
Start situation
System should be able to offer a combination of design and runtime adaptation:- author’s design knowledge & ‘system’ knowledge- learner profile & peer similarity
System should avoid proprietary models and representations: - re-usable components- open architecture

NIntroduction
Standards
Adaptation in aLFanet deliberately builds on a combination of e-learning ‘standards’ -increased initial investment but higher potential
IMS LD: an explicit instructional design (any IDM)-- --
IMS Metadata (IEEE LOM) : the contents IMS LIP: the userIMS QTI: formal progress-- --
All delivered in IMS CP
Challenge at the start of the project:- combined use of specifications- (very) limited experience and tools

Course and material design
Central in the cycle is the design created in
Learning Design (the template). The design
contains the logic for the pre-designed
adaptations and provides the hooks and the
information upon which the runtime adaptation
bases their reasoning. This combined with an
analysis of the actual user interactions lead to the
recommendations, adaptive dynamic tests & audit
reports.

Course and material design
Auditing is aimed to provide input about how
successful the design is.
Audit reports include:
- the actual activity sequence- use of the learning objects- satisfaction statistics
Adaptation – a full life cycle
Auditing example:
• analyse the study path (actual activity sequence)

NFindings
LMS+ an adaptive (open) e-learning system: design & runtime adaptation
standards based & integrated+ a set of reusable (open source) components:
LD- & QTI authoring tool & LD- & QTI engine; Adaptation- & Interaction package
- interface & performance
The Authoring process:- lack of integration- too many details- spec. constraints & adaptation constraints+ use of templates
