Maurice Hendrix, IAS seminar, 30/06/ Concept Adaptation Model CAM

Outline Adaptive Hypermedia Authoring now: LAOS Graphical Authoring: CAM

Adaptive Hypermedia Hypermedia Adaptive Richer learning experience

LAOS 5 layer model for AH authoring: Domain model (DM) Goal and constraints model (GM) Adaptation model (AM) User models (UM) Presentation model (PM) Authoring now: LAOS

Authoring now: DM & GM Several tools like MOT (My Online Teacher) Efforts to automate part of the process Can easily be done by teachers without CS background

Example DM authoring

Authoring now: AM Either pre-prepared strategy or programming knowledge required Difficult for non-CS teachers to go beyond provided strategies

Example AM authoring (LAG Language) initialization( PM.next = true PM.ToDo = false PM.menu = true while true ( PM.GM.Concept.show = true UM.GM.Concept.beenthere = 0 ) UM.GM.begnum = 0 UM.GM.intnum = 0 ….

Graphical Authoring: CAM Layered model for AH authoring: Domain model (DM) A number of Adaptation models (AM 0.. AM N ) (GM can be done using AM 0) User models (UM) Presentation model (PM)

Example Graphical Authoring

Graph based authoring not completely new e.g. WOTAN

Example Graphical Authoring Using generic placeholders

Example Graphical Authoring Conditions

Termination and confluence problem Termination and confluence not guaranteed Between layers this can be solved by run-time priority: a rule on a lower layer cannot change an attribute changed by a rule on a higher layer

Further work 1.More concretely develop CAM 2.Develop tool for authoring CAM 3.Develop tools for AH systems to import CAMs
