Adaptivity and Personalization in Learning Systems

How can we make learning systems more adaptive intelligent and personalized more adaptive, intelligent and personalized

 Based on a comprehensive student model that combines

learner information and context information learner information and context information

 In different settings such as desktop-based, mobile and

ubiquitous settings

Adaptivity and Personalization in Learning Systems

 Adaptivity based on learning styles

 Automatic identification of learning styles based on

students’ behaviour

 Dynamic identification and updating of learning  Dynamic identification and updating of learning

styles

 Adaptive course provision based on learning styles 4

Identifying Learning Styles

 Automatic Approach  Identifying learning styles is based on patterns of behaviour  Identifying learning styles is based on patterns of behaviour  Commonly used types of learning objects were used

(Content objects, Outlines, Examples, Self-assessment tests, Exercises, Discussion forum) and relevant patterns were derived from these types of learning objects

 Calculation of learning styles is based on hints from

g y patterns

 A rule-based mechanism is used for this calculation (similar

to the approach used in the questionnaire) to the approach used in the questionnaire)

 Evaluation with 75 students showed that the instrument is

suitable for identifying learning styles (results: accuracy of 73% 79% )

Adaptive Course Provision

 Developed an adaptive mechanism  Incorporates only common types of learning objects

Incorporates only common types of learning objects

 Content  Outlines  Conclusions  Examples  Self-assessment tests  Exercises

 Adaptation Features

 Adaptive sequencing of examples, exercises, self-assessment

tests, outlines and conclusions Ad ti th b f l d i

 Adapting the number of examples and exercises

 Teachers have to:

 Provide learning objects

 Annotate learning objects (distinguish between the objects)

Adaptive Course Provision

 Evaluation with 437 students showed that:

 Matched Group: less tim e and equal grades  Mismatched Group: ask m ore often for

additional learning objects additional learning objects  Demonstrates positive effect of adaptivity

 Extension with respect to  Extension with respect to

 Include more types of learning objects  Make adaptive mechanism adaptable for teachers  Make adaptive mechanism adaptable for teachers 8
