Motivation

• Creation of adaptive content is crucial to the popularisation of A(E)H.

• 2 separate challenges for Authoring AH– Content Creation– Strategy Creation

• MOT focuses on Content Creation

LAOS Framework• Hierarchy of concepts

• Each concept contains attributes

• Standard attributes include:• Title (required)• Text• Keywords• Exercise• Introduction• Conclusion

Domain Model

LAOS Framework

Goal Model

• Hierarchy of sublessons (or groups of sublessons)

• Each sublesson is a link to a concept attribute

• Sublessons (or groups) can be labelled/weighted

LAOS Framework• Content in concepts and attributesDomain Model

• Describes goals of lessonGoal Model

• Stores data about userUser Model

• Strategy for showing/hiding contentAdaptation Model

• How the content is shownPresentation Model
