JavaBeans as a Framework for Collaborative Software

We describe the use of a popular component framework, JavaBeans, to facilitate developing collaborative software. We describe the class of collaboration-unaware components that can be effectively shared under this framework, and an extension that supports development of efficient collaboration-aware components

Classroom BRIDGE: using collaborative public and desktop timelines to support activity awareness

Classroom BRIDGE supports activity awareness by facilitating planning and goal revision in collaborative, project-based middle school science. It integrates largescreen and desktop views of project times to support incidental creation of awareness information through routine document transactions, integrated presentation of awareness information as part of workspace views, and public access to subgroup activity. It demonstrates and develops an object replication approach to integrating synchronous and asynchronous distributed work for a platform incorporating both desktop and large-screen devices. This paper describes an implementation of these concepts with preliminary evaluation data, using timelinebased user interfaces
