Multimodality and Context Adaptation for Mobile Learning

Cloud-based framework for mobile learning content adaptation

“…Basically m-Learning is considered as any form of learning that is delivered through a mobile device. We believe that m-Learning can be presented as a mobile extension of e-Learning through mobile computational devices with Internet connectivity [3]. At the same time mobile devices significantly differ from each other in their characteristics.…”

“…The Google App Engine [14] provides a Java Web framework based Jetty, a servlet container, and BigTable for data storage. Xesop [3] uses the Apache containers suite for data storage and service management.…”

“…The contribution is as follows: (1) the concept encompasses the creation of an XML-based and mobile browser-independent content, which is adapted to the requesting device using a device capability recognition method and XML transformation techniques according to the recent advances of media queriesbased responsive Web design; (2) personalization in m-Learning via an adaptive approach; (3) demonstration of a Web service-based architecture to an integrated Web-based learning and m-Learning environment; (4) testing of several mobile Web browsers to proof Learning Objects (LOs) [3] portability; (5) design of a service-based framework, as part of an e-Learning SaaS Cloud, that uses hierarchical displaying multimedia units with index extraction and content summarization; (6) description of a SaaS-based e-Learning system architecture to provide a flexible integration model in which all the learning components and applications are well defined and loosely connected and (7) deployment of multimedia services and espe-cially the presentation of multimedia content on mobile environments, which is a more challenging task due to the diversity of mobile devices and their parameters The objective of this contribution is to combine semistructured data, stored in a Native XML Database (NXDB), with structured data stored in a Relational Database (RDB) through Web services (WS) called by a Learning Course Management System (LCMS). Thus, we provide direct data integration located at distributed sites in order to improve the achievement of learning outcomes.…”

“…We tested several mobile Web browsers to proof the Learning Objects (LOs) [7] portability. The advantages of using a mobile Web browser as universal communication environment were described in [3]. We introduce a service-based solution that utilizes the hierarchical display of multimedia units with index extraction and content summarization.…”

“…An adaptive technique is realized on XML-based technology which is better suited for a large content of LOs. The use of XML as a medium-neutral data format for data storage and processing allows the learning contents to be classified hierarchically, to be structured at the desired level of granularity and to be adjusted to different contexts and devices [3].…”
