Integrating Technical Advance in Mobile Devices to Enhance the Information Retrieval in Mobile Learning

It has been a long time since the wireless technology is used for the interaction between teacher and learners in learning activities. The recent advance of the mobile technologies has created new chances improving the flexibility, efficiency, and functionality of the learning interaction systems. This investigation identifies the weakness of the existing systems, and integrates the emerging mobile technologies to establish an open interaction framework to effectively enhance the interaction using students faced mobile devices and public wireless infrastructure. The main work of this investigation contains: (1) a teacher-learner response model for mobile based interaction is proposed and is described with state machine logic; (2) a presentation-content retrieval mechanism is designed to efficiently utilize the limited resource; (3) the device independent and context-aware techniques are integrated to created cross-platform application with mobile device features; (4) an open media framework is created for flexible learning material distribution and question organization. A lightweight mobile oriented web-based wireless response system (mobile-WRS) is implemented as a case study. In-house testing and classroom application of the mobile-WRS in universities demonstrate that the proposed system outperforms the peer works in usability, interface, operational efficiency, learning material distribution, results presentation and performance assessment, etc.
