1a. 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)

1b. Adaptation: a full life cycle

Adaptation is a complex interactionbetween design time logic and knowledge & run time observations. The results appear as: - direct changes, - recommendations or - advices

ALFanet supports this complex process in a 4 step life cycle.

1c. Adaptation supported by standards

Adaptation in aLFanet deliberately builds on a combination of e-learning standards -increased initial investment but higher potential :- open architecture- re-usable, open source components

IMS LD: an explicit instructional design (any IDM)-- --

IMS Metadata (IEEE LOM) : knowledge of the contents IMS LIP: knowledge of the userIMS QTI: formal progress-- --

All delivered in IMS CP

Note: 1st integrated application with these 5 standards

• LD- & QTI authoring tool; • LD- & QTI engine; • Adaptation- & Interaction package

Course and material design

Central in the adaptation process 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 and adaptive

dynamic tests.

Course and material design

Auditing is aimed to provide input about how

succesful the design is.

Audit reports include:

- the actual activity sequence- use of the learning objects- questionnaires- satisfaction statistics


Auditing example:

• analyse the study path (actual activity sequence)

NConclusions

- defined adaptation- the support for standards - the life cycle of adaptation- an adaptation catalogue- a solid contribution to knowledge & further R&D

- an adaptive (open) e-learning system: templates, tools, presentation layer & reports- a set of reusable (open source) components:

LD- & QTI authoring tool; LD- & QTI engine; Adaptation- & Interaction package

3. Collaboration & Presentation – EDP pilot

4. Audit reports – OUNL pilot
