1. Tells - a facility for web-based, remote real time laboratory experiments University of Limerick Ireland

2. Classroom of the future2 The (Tells) system is a facility to enable lecturers and students to run and control real-time experiments. The main goals of (Tells) are: The provision of lectures augmented with real- time experiments and demonstrations to local and remote learners The provision of remote and local learner access to real-time experiments on-line for 24 hours a day 7 days a week Building on standard Internet and PC technology and LABVIEW

17. Classroom of the future17 Conclusion The (Tells) system is a facility that enables communication between lecturers, laboratory experiments and students. It is implemented using standard, available hardware and software. It is a resource that can be applied in any experimental discipline where interaction with real-time experiments is a useful learning resource.
