The potential for adaptable accessible learning objects: A case study in accessible vodcasting

摘要

With the rapid development of wireless networks and mobile technologies and the increasing adoption of mobile learning, the need for 'anywhere, anytime and any device' access to information becomes more evident. This has influenced the design of learning objects. The small but developing literature on vodcasting indicates its potential as an effective learning resource for use in education. This paper explores the use of vodcasting in terms of accessibility and, through a specific use case, investigates the adaptations required for existing learning objects delivered as vodcasts (videos downloaded to an MP3 player). The case study is examined in the context of a larger research initiative which aims to contribute to the requirements specification for the development of an adaptable learning object authoring tool, and suggests a learning object adaptation service which allows for flexibility and personalisation to learners' needs and preferences. Detailing the theoretical aims, design, implementation and evaluation of the project, the paper supports the argument for the educational use and value of vodcasting, but also highlights potential limitations and problem areas.
