Adding intelligence to a learning environment: learner-centred design?

The development of a specific learning environment into an intelligent learning environment (switchER II) is used as the basis of a discussion about the nature of 'learner-centred design' - an approach which is contrasted with user-centred design, and is being advocated as an important move in the development of effective educational computing systems. An analysis of the notion of learner-centred design leads to the need to develop appropriate methodologies to support learner-centred design, to ensure that individual differences are respected, and that Artificial Intelligence techniques are applied appropriately.
