We are building a collaborative learning environement that supports teams of students as they collaborate synchronously and remotely to solve situated, multi-step problems involving algebraic modeling. Our system, named Algebra Jam, provides a set of tools to help students overcome two of the most serious impediments to successful collaboration:(More)
In this paper we describe a speech recognition system for teaching reading skills to young children, and various research issues and activities necessary to make the system work. A full-scale application is described, which embodies the research. The application interacts with a child to help him or her read, and provides opportunities for the child to show(More)
An understanding of risks to biodiversity is needed for planning action to slow current rates of decline and secure ecosystem services for future human use. Although the IUCN Red List criteria provide an effective assessment protocol for species, a standard global assessment of risks to higher levels of biodiversity is currently limited. In 2008, IUCN(More)
This paper considers different ways to enhance access to the World Wide Web for persons with sensory, cognitive, or motor limitations. Paradoxically, while complex Web architectures may seem to have inhibited accessibility, they have broadened the range of points where we can try to improve it. This paper identifies these points and evaluates the advantages(More)
Older adults differ from younger ones in the ways they experience the World Wide Web. For example, they tend to move from page to page more slowly, take more time to complete tasks, make more repeated visits to pages, and take more time to select link targets than their younger counterparts. These differences are consistent with the physical and cognitive(More)

Users of complex applications need advice, assistance, and feedback while they work. We are experimenting with “adjunct” user agents that are aware of the history of interaction surrounding the accomplishment of a task. This paper describes an architectural framework for constructing these agents. Using this framework, we have implemented a(More)
