Adapt

1
Adapt

• Adaptivity and adaptability in ODL
• (Minerva/Socrates project)

2
Background I

• A network of 6 European universities(Eindhoven,
  Twente, Milano, Trento, Southampton and
  Nottingham)
• Aim to produce a series of guidelines for good
  practice for authoring in EAH (educational,
  adaptive hypermedia) systems.

3
Background II

• Investigation of current EAH systems to determine
  adaptive patterns, possibly develop a taxonomy
  of these.
• Good vs. Bad ?
• What are Patterns?

4
Patterns

• Design Pattern ltrecurrent problem, heuristic
  solutiongtEAH design pattern ltteaching
  goal, customised design propertiesgt

5
Patterns

• examplewe are using an EAH to teach mathsour
  teaching goal - is to teach each student at a
  level appropriate to their understandingour
  customised design is to alter the
  presentation of material to be relevant for that
  student.

6
Design Dimensions

• Identified high level patterns
• Content Domain
• Learner Model
• Instructional Views
• Adaptation Rules
• Detection Mechanism
• the Content and Learner Domains will now be
  expanded upon

7
Content Domain

• Types
• Fact
• Principle
• Example
• Formal Definition
• Procedure
• Theory
• Demonstration
• Etc .

8
Learner Model

• Types (which learner attributes)
• Domain dependant aspects
• User knowledge of a given concept (m/M, V)
• Background Knowledge (M, S)
• Motivations (M), Goals (M/m), Tasks (m)
• Performance (M/m)
• Scaffolding required (M/m)
• Time to Complete

9
Learner Model

• Domain independent aspects (M, S)
• Learning Style
• Personality
• Sex
• Accessibility Issues
• How?
• Overlay Model (1-n mapping from concepts to user
  micro attributes)
• Stereotype Model (for Macro attributes)

10
Next

• Take a subset of these design patterns and create
  an authoring system.
• Why?
• Current authoring systems do not cover anything
  more than creation of content. Even then there
  are no guidelines for the creation of content in
  an adaptive system.
• Re-use of extant materials

11
Next

• Aim
• Full specification of an adaptive authoring
  system.
• System to author adaptive structures
  (lessons/tutorials) and the content to address
  them.
• Creation of a prototype

12
Prototype

• Use a rule set created for EAH systems.
• Output from a generic tool for specific systems
  (e.g. WHURLE, MOT, AHA!)
• example
