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 attributes Domain Model Describes goals of lesson Goal Model Stores data about user User Model Strategy for showing/hiding content Adaptation Model How the content is shown Presentation Model

My Online Teacher Developed since 2000 Focuses on –Domain Models –Goal Models Imports/Exports CAF (XML) –Compatibility with other AH systems such as AHA!

MOT3.0 Complete rewrite of MOT1.0 –Focuses on usability –Uses PHP and AJAX

MOT3.0 Replaces static HTML pages with AJAX Uses jsTree to display hierarchies –Allows drag & drop reordering

MOT3.0 Adds search function Adds Yahoo! UI (X)HTML editor

Interoperability Import from non-adaptive educational material –IMS-CP –IMS-QTI –SCORM

Semi-Automatic Authoring Focus on reusing existing content –MediaWiki –Microsoft PowerPoint

MediaWiki Importer Extracts concepts from WikiText Parses other WikiText into HTML then stored in text attribute

Presentation Importer Files converted using OpenOffice.org Each slide creates a concept with attributes: –Text –Image –Notes

Future Research Extend MediaWiki importer –Extract keywords from articles –Crawl/Import related topics How deep?! Six Degrees of Seperation?

Future Research Extend Presentation importer –Use slide titles to create deeper hierarchy

Summary Adaptive Hypermedia Authoring LAOS Framework MOT3.0 Usability Improvements Semi-Automatic Authoring Techniques Future Research
