Problem Overview

Problem Sketch • Document adaptation – LMSs (in general) do not provide options for mobile device screen size and resolution adaptation
• Adjustment in m-Learning means – A learner-centric content; – A suitable context-aware pedagogical content adapted to learning preferences, profiles and requirements. – An eLSaaS framework combines various data (LOs) through Web services to provide direct data and application integration for m-Learning usage.
• SaaS approach is suitable for m-Learning – Reduces maintenance efforts (no central LCMS) – Allows sharing of pedagogical resources; – Requires (only) a Web browser as the unified client. CSEDU 2012

Cloud Adaptation Technique • The proposed content adaptation technique – Course authors should prepare flexible learning materials that can be accessed across contexts by dividing the page into smaller chunks and putting them on multiple hyperlinked pages surrounded by an index to facilitate the access to a requested content with the objective to face the complexity of the rich multimedia content.
• The Cloud contribution – – – –
Promotes the virtualization of learning objects; Abstracts LMSs as a set of distributed services; Needs a unified client, i.e. the Web browser; Supplies a customizable/adaptable user interface (user context); – May support a (semantic) service layer for learning objects’ discovery and assembly CSEDU 2012

Contextualization • The content adaptation schema

Edited course
Adaptation service
Course structure
XML view

Conclusion and Future Work • We presented a cloud-based m-Learning solution – More and more mobile applications will be based on (connected to)cloud services; – Cloud services promote the use of mobile Web browsers instead of mobile applications since the cell phones are not powerful or fast enough; – Cloud approach promotes the availability of various services • e.g. a speech-production service where a method sends a text and generates speech files;
• Future Work – Use mash-ups in a context-aware situation to connect resources and applications to better fit the needs of individual users. – Build a semantic adaptation layer CSEDU 2012
