An investigation into the effects that digital media can have on the learning outcomes of individuals who have dyslexia

The effects that media can have on task performance have been greatly debated over the years. Whilst agreement has begun to emerge on the effects media have on cognitive performance, little is understood about the relationship between such media effects and individual differences such as individuals who have dyslexia. This paper presents findings from a study that investigated the effects computer-based media can have on the learning outcomes of individuals who have dyslexia. The purpose of the study was to obtain data that informed the development and design of e-learning and distance learning materials for universal use. The research process was based on Dual Coding Theory and refined by current theories on dyslexia. Findings from the research are intended to help academics and providers of e-learning materials to improve the design and delivery of their learning contents.

When humans form media and media form humans: An experimental study examining the effects different digital media have on the learning outcomes of students who have different learning styles

A set of computer-based experiments are reported that investigate the understanding achieved by learners when studying a complex domain (statistics) in a real e-learning environment using three different media combinations-Text only, Text and Diagrams and Spoken Text and Diagrams, and the results agree with earlier work carried out on more limited domains. The work is then extended to examine how student interaction and student learning styles affect the learning outcomes. Different responses to the media combinations are observed and significant differences occur between learners classified as Sensing and Reflective learners. The experiment also identified some important differences in performance with the different media combinations by students registered as Dyslexic. The experiment was therefore repeated with a much larger sample of Dyslexic learners and the earlier effects were found to be significant. The results were surprising and may provide useful guidance for the design of material for Dyslexic students.

Computer Imagery and Visualization in Built Environment Education: The CAL-Visual Approach

UK higher education institutions have invested significantly in the implementation of communication and information technology (CIT) in teaching, learning and assessment - with mixed results. This work investigated the use of multimedia technologies in the form of digital imagery and visualization material to improve student knowledge and understanding. In this context, this paper reports on a major UK initiative (CAL-Visual) funded by the Higher Education Funding Council as part of the Teaching and Learning Technology Programme looking at improving the use of images for teaching and learning in built environment education. It first describes ways in which computer-aided learning (CAL) is being used in civil and building engineering curricula, it then presents the main aims and objectives of the project and describes the design and implementation of the CAL-Visual system. It concludes by reporting on the results of an evaluation conducted using case studies relating to different applications.

Supporting the life-cycle of multimedia and visualization using distributed performance support systems

UK Higher Education Institutions have invested significantly in the implementation of multimedia and visualization material in teaching, learning and assessment of civil and building engineering-with mixed results. The paper focuses on the use and life cycle of digital imagery and visualization material, which is embedded within multimedia teaching aids to improve student understanding. It describes ways in which these materials are developed and used in the civil and building engineering curriculum and, in particular, how distributed performance support systems can be applied to make more effective use of digital imagery and visualization material. Following this, the paper then describes how a distributed performance support system approach to education is being adopted at Loughborough University as part of the CAL-Visual project. After highlighting the main aims and objectives of the project, the paper concludes by discussing some of the issues encountered during the design and implementation of a distributed performance support system.
