E-learning is frequently technology-led rather than theory-led. In moving from a traditional face-to-face experience to an electronic experience, the combination of video and other multimedia elements alongside text-based materials are able to simulate the 'real' and create an engaging experience for learners and provide opportunities for learning which would not have been possible within the traditional experience alone.
"It is unlikely that eLearning practice will continue to evolve unless the theoretical underpinnings of eLearning are explored and debated providing a wider platform and a common philosophy for eLearning development"

communication, an attempt to deliver eLearning could actually end up just being independent study. The use of video and audio encourages emotional and active engagement with the learning process, providing pictorial and verbal representations of the material. There is consistent evidence to support the view that people learn more deeply from text and pictures than from words alone. Visual information supports learning, and 75 per cent of our ability to learn can be attributed to visual perception. There are numerous facets of the learning experience that video can provide that cannot be conveyed through text and the gains in economies of scale for delivering teaching across the web are obvious. The capabilities of straeming video have improved so conderably that the quality of the image picture is no longer significantly reduced as a result of compression. The presence of an animated guide or a video of a human face improves the interaction of the student with the material and so enhances learning.
