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.

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


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

NWays forward

The authoring process:

- emphasis on integration

- propagation of choices and knowledge (2 levels)- use of (parts of) templates

OR

- Limited purpose dedicated authoring tools
