1
First International Workshop on Authoring of
Adaptive and Adaptable Educational Hypermedia

• At the WBE04 conference,
• 19 February, Innsbruck, Austria

2
Authoring of Adaptive and Adaptable Educational
Hypermedia Where are we now and where are we
going?

3
Major Questions of the Workshop

• Why should we look at the authoring process in
  adaptive educational hypermedia design?
• How does detecting authoring patterns help the
  process?
• Why do we need to consider cognitive styles in
  adaptive hypermedia?
• What do these seemingly unrelated topics have in
  common?

4
Goal of workshop

• to attract interest of the related research
  communities to this important issue of design and
  authoring in adaptive hypermedia, and
• to discuss the current state of the art in this
  field.
• These discussion should lead to a better
  understanding and formulation of the possible
  patterns to extract from the authoring process in
  AH.

5
Organization

• Only a few papers selected for presentation
• Presentation lasts max. 10 min
• Discussion of paper max. 5 min
• List of major questions, open questions, and
  pattern description task distributed
• Next, discussion on workshop major questions,
  based on papers
• Discussion on open questions
• Discussion on pattern descriptions
• Hand-in pattern descriptions, list of major
  open q. (!!)

6
Outline

• AEH
• Adaptation questions
• AEH authoring questions
• Workshop themes papers
• Patterns
• Open questions

7
AEH

• Adding personalization (flexibility) to an
  otherwise inflexible educational environment

8
Adaptation questions

• what kind of adaptation should be done?
• to what this adaptation should respond?
• and, to the more technically oriented
• When? and
• how this adaptation should be performed?

Answer with the author!!!
9
Authoring AEH

• State of art?

10
AEH authoring questions

• what functionality? (minimum for enough
  flexibility)
• AEH components creation order
• how to reduce the authors load? (without
  decreasing flexibility)
• repetitive steps saved reproduced automatically
  
• reuse materials adaptive techniques and
  pedagogical approaches

11
Workshop Themes and their Motivation

• Good practices of user modeling based adaptation
  in education (1)
• Basis of AEH authoring (UM main driving force
  in AEHs)
• Ideally, authoring tools should at least
  reproduce the most successful AEHs built so far.
• Authoring of adaptive/ adaptable educational
  hypermedia (2)
• Next step Authoring methods (and tools) for AEH
  (several types, to be analyzed compared)
• Design patterns for educational adaptive
  hypermedia (2)
• Authoring patterns in adaptive/ adaptable
  educational hypermedia (1)

12

• Connecting AEH to learning and cognitive styles
  (3)
• Because patterns can be found at higher level
• Collaboration authoring issues for adaptive/
  adaptable educational hypermedia (1)
• Between authors
• Patterns can allow it because patterns allow
  reuse.
• Adaptation model transformations between adaptive
  educational hypermedia systems (0)
• Patterns allow transformations between AEHs (as
  in Open Hypermedia)

13
Workshop paper order

• Start past good practices of AEHs which we
  would like to reflect in our model of authoring.
• C. Conati A. Bunt, Student Modeling for Open
  Learning Adaptive Hypermedia
• Then authoring problem how this was solved up
  to now,
• P. Cristea, R. Tuduce C. Popa, Test Authoring
  for Intelligent e-Learning Environments
• P. Karampiperis D. Sampson, Knowledge Modelling
  for Adaptive Content Selection in Educational
  Hypermedia Systems,
• We try to extract patterns of authoring directly
  from the authoring process.
• A. Moore, C. Stewart, D. Martin, T. Brailsford
  H. Ashman, Links for learning linking for an
  adaptive learning environment

14

• One step of abstraction further transforming
  authoring patterns into design patterns for AEH.
• P. Avgeriou, D. Vogiatzis, A. Tzanavari S.
  Retalis, Design Patterns in Adaptive Web-based
  Educational Systems an Overview
• Among them interesting high-level patterns
  based on learning styles
• P. Paredes P. Rodriguez, A Mixed approach to
  Modelling Learning Styles in Adaptive Educational
  Hypermedia
• N. Stach, Incorporating Cognitive Styles in AHA!
  (The Adaptive Hypermedia Architecture)
• Finally extensions for AEH authoring for
  collaboration.
• M. Kravcik M. Specht, Authoring Adaptive
  Courses ALE Approach

15
Pattern

• each pattern describes a problem, which occurs
  over and over again in our environment, and then
  describes the core of the solution to that
  problem in such a way that you can use this
  solution a million times over.

Pattern analysis

• name,
• problem,
• context,
• forces,
• solutions,
• related patterns and
• known uses

17
Open questions

• How to correctly extract authoring patterns for
  AEH?
• implications of this extraction of patterns?
• It is evident that it is not really possible to
  create authoring tools for every situation and
  adaptation method the limitation being given by
  authoring tool design constraints.
• Aim
• making the authoring process easier,
• various different systems compatible with each
  other.
• functionality patterns need to be evaluated.

18

• We are very pleased to have gathered experts to
  discuss these issues within the workshop and are
  hoping for useful results from these discussions.
