Educational scenarios for cooperative use of Personal Digital Assistants

Abstract Based on experience in orchestrating collaborative learning scenarios with ubiquitous computing technology, three approaches for extending co‐constructive modelling and discussion environments with Personal Digital Assistants (PDAs) connected through a wireless network are described. One application is an annotation tool, the second one replicates a modelling system on the PDA and the third one makes use of a wireless optical reader in addition to the PDA. They all provide ‘lightweight’ synchronisation mechanisms in PC‐based environments. General design and implementation strategies for such extensions are discussed in terms of model, view and controller.
