Contents • Motivation • Application of learning styles adaptation language (LAG-XLS) in AHA! (Adaptive Hypermedia Architecture) • Experimental Assignment • Conclusions
“Authoring problem” Defining:- content alternatives & multiple paths through the content - adaptation techniques - whole user-interaction mechanism design Motivation 1 Alleviating “Authoring problem”Improving reuse capabilities:(reuse of previously created material & other components)reuse of static & dynamic parts of the courseware Our solutionReuse of dynamics based on LS example:Adaptation language LAG-XLS (read as “LAG-excels”)
Evaluation of LAG-XLS:- understanding strategies creation and application- satisfaction with the presentation- ability to express variety of strategies Motivation2
Contents • Motivation • Application of learning styles adaptation language (LAG-XLS) in AHA! (Adaptive Hypermedia Architecture) • Experimental Assignment • Conclusions
Types of Adaptive Strategies in LAG-XLS • Instructional strategies - selection of media items - sorting information items - providing different navigation paths (breadth-first vs. depth-first) • Instructional meta-strategies – inference or monitoring strategies. Preferences for: - certain types of information (eg. text vs. image) - reading order (eg. breadth-first vs. depth-first)
Contents • Motivation • Application of learning styles adaptation language (LAG-XLS) in AHA! (Adaptive Hypermedia Architecture) • Experimental Assignment • Conclusions
Experimental Assignment • AHA! installation • Involvement as: - authors (using Graph Author tool, working with given applications & predefined strategies) - end-users (strategies visualization in given applications) • Comparison of stated preferences and preferences induced by the system with Felder-Soloman ILS questionnaire results • Modifying the existing strategies or creating new strategies • Comments
Comparison: own stated preferences and ILS questionnaire results (in %)
System induced preference the same as questionnaire result? (%)
Contents • Motivation • Application of learning styles adaptation language (LAG-XLS) in AHA! (Adaptive Hypermedia Architecture) • Experimental Assignment • Conclusions
Conclusion 1 • Students considered application of LS in AH a useful endeavor • Theory and praxis do not always match in LS identification • Students understood strategies application in AHA! quite well and were satisfied with the presentations • However the students did not create any new strategies
Conclusion 2 • Creation of a course that supports LS requires a lot of psychological knowledge • Creation of ready to use strategies can be useful • Experiments with LS specialists are necessary
