AUTHORING ADAPTATION



                        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)

                        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

                       Adaptation in aLFanet deliberately builds on a combination of
                       e-learning ‘standards’ -increased initial investment but higher
                       potential

                       - combined use of specifications
                       - (very) limited experience and tools

     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.
