I’ll briefly now touch upon how we tackled the recommendations we received from you in the past. One thing you expressed was scepticism about how the prototypes will have a positive impact on T&L. We, therefore, arranged the programme of this review in a way to demonstrate this potential , and through our validation plan and efforts to show encouraging evidence from end-users. This will be discussed in the service demos. A word of caution: It’s important that one cannot put all services on the same comparative level. We developed a divers set of tools that share two common objectives – CLICK BUT: they are like forks and knives, made for different settings, and to help tackle different educational challenges. Some support learners other tutors. I believe that when you get introduced to our tools you will realise that this diversity is a strength because it allows for a number of useful combinations and applications.

What can language technologies do for us? <ul><li>Intelligent support in two areas of TEL : </li></ul><ul><li>help tutors and teachers support learners </li></ul><ul><li>help people learn </li></ul><ul><li>with language technologies encapsulated into the right set of tools </li></ul>
<ul><li>„ A range of computational techniques for analyzing and representing naturally occurring text at one or more levels of linguistic analysis (e.g., morphological, syntactic, semantic, pragmatic) for the purpose of achieving human-like language processing for knowledge-intensive applications .“ </li></ul><ul><li>– AHIMA body of knowledge </li></ul>

Learning Services & PLE Monitor progress against learning objects , outcomes , traces of others for creative sense making of the past and in support of future planning 1 Building and sustaining learning environments of people, artefacts, and tools involved in activities supporting construction of information and knowledge 2 Effective and efficient arranging of time , space , and resources to foster activities of constructing information and knowledge 3
PLEs <ul><li>A landscape of tools (institutionally offered or personally chosen) that brings a learner together with others and content artefacts in activities that support in constructing and processing information and knowledge. </li></ul>
PLE Architecture Users involve in use-cases . Each case deploys widgets in support of the given task. Widgets use infrastructure services & data (from within the PLE container or from the Web 2.0). A directory serves the management and deployment of the portfolio. Interoperability standards secure the flexible recombination of widgets, services, and data.
