TRANSCRIPT
Overview
Affordable virtual spaces for cooperative learning
• Computer-supported collaboration
scripts
• Synchronous cooperative exercises
• Community support and scaffolding
in CURE
Computer-supported collaboration scripts
• Prescribe possible behaviour through – States, – Roles constraining actions, and – Transitions (changing state and role assignment)
• Experimental study comparing different features– Collaboration script– Explicit referencing
=> positive impact of referencing for complex knowledge
• Planned:– Comparing different UI designs for integrating awareness – Development environment for collaboration scripts
Synchronous cooperative exercises (1)
• Special tool for a specific form of exercise– Brainstorming– Organizing concepts into a
semantic net
Synchronous cooperative exercises (2)
• Used in 2 courses; log data and group results analyzed– Voluntary participation– Groups (3-4 students) formed and
mostly stayed together– Interaction changed over 3
sessions• social relationships formed• Less coordination
– Groups did learn, discourse facilitated deeper insight
Community support and scaffolding in CURE (1)
CURE (Collaborative Universal Remote Education)– Rooms: shared workspaces for groups– Rooms provide:
• Pages: learning material & tools• Communication channels• Awareness
– Adjacent roomsform learning environment
– Templatescontrol presentation and structure of pages

Community support and scaffolding in CURE (2)
• Community Support– Managing collaborative spaces
• Create/manipulate rooms• Access management• Communication: chat, discussions• Cooperation: shared pages• Coordination
– Change notifications
– Shared plans (pages)
– Calendar, meeting scheduler
– Group formation– Tailoring
Community support and scaffolding in CURE (3)
• Scaffolding– Organizing learning activities in rooms and
pages– Explicit instructions, milestones– Organization
• Predefined (teacher)• Self-organized• Tailoring
– Planned:• Integration of collaboration scripts
Personal background
• 1989-2001 at GMD-IPSI– Cooperative, open hypermedia systems– CSCW: authoring, meeting support, problem-
solving– CSCL: collaboration scripts
• Since 2001: FernUniversität in Hagen– Teaching: Distributed cooperative systems– Research: CSCL, support for cooperative learning
among distributed students (and teachers)
