Adaptation - introduction
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)

Adaptation - introduction
1b. Adaptation a full life cycle

• Adaptation is a complex interaction
• between 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.

5
Adaptation - introduction

• 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

Adaptation a full life cycle
Course and material design
Publication
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.

• 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
