Plenty of systems are presented at the Wireless and Mobile Technologies in Education Conference. I don't know if had to refer to them by 'current' or 'future' trends (it's 'current' for academics but certainly 'future' for practitioners though some teachers already use them). Current (future?) trends:
- student ID constructed using a cell-phone (Kobayashi et al., 2005)
- augmenting class-rooms with a digital pen and RFID tags (Miura et al., 2005)
- an intelligent tutoring system that adapts to location-related features (as well tolearner knowledge and to time available for study) (Bull et al, 2005)
- Using SMS for quizzes (Tretiakov et al., 2005) which gave a good user acceptance.
- PDA used as a remote-control lab (wu et al., 2005)
- An interactive logbook to support learning across institutions/workplaces (Chan et al, 2005)
- Using mixed reality simulations to embed tangible interactions in order to create relevant metaphot, for instance to explain astronomy (Eisen et al., 2005)
- Dual-device architecture for learning using both cell phone and interactive television (Fallakhair et al., 2005)
- Using wireless devices as response devices/polls (Chen et al., 2005)
- Handheld and large-display groupware (Liu et al., 2005)
- Using PDAs for speech testin g(Yang et al., 2005) (Uther et al., 2005)
- Usage of lifeblog in mobile learning: recording aspects of living on a blog, by mobile phones (Hartnell-Young and Vetere., 2005))
- Course-management, student-support or mobile access to course material through cell-phone (Houser and Thornton, 2005) (Riordan and Traxler, 2005) (Mermelstein and Tal, 2005)
- Usage of computationaly-enhanced construction kit to teach programming (Buechley et al., 2005)
- Usage of a programmable set of construction kit for teaching (Elumeze et al., 2005
- Using RFID for digital library infrastructure (Morales-Salcedo et al., 2005)
- Usage of camera-phones to create a large repository of multimedia information (connected with location and context information through visual codes) (Mitchell and Race, 2005)
Of course all are not interesting or relevant, I just wanted to give an overview of the picture. The conference also had papers that concerned systems evaluation.
