The popularity of immersive simulated environments for experiential learning is growing; and will be a part of tomorrow's learning technologies in the key area of adult training. The major challenge is to effectively align the learning experience in the simulated environment with the "real" world context and "day-to-day" job practice. ETU has secured a substantial R&D grant from the EU, under its Framework 7 research programme with a total budget of over €4 million, to collaborate with technology enhanced learning leaders across Europe. The project, starting October 1st 2010, will research and develop a set of metacognition and reflection services to personalise online scenario based learning to a users past experiences and working context. This will help ETU to achieve levels of realism and proximity to daily working practices within the training environment previously not possible.
