Prior research has established that active participation and collaboration by students results in multiple benefits during wiki-based CSCL activities. However, achieving such behavior can be a challenge without external motivation. To increase active participation and collaboration by users, we developed an enhanced wiki called the Written Agora.

— Recent years have seen a surge in the use of intelligent computer-supported collaborative learning (CSCL) tools for improving student learning in traditional classrooms. However, adopting such a CSCL tool in a classroom still requires the teacher to develop (or decide on which to adopt) the CSCL tool and the CSCL script, and design the relevant(More)
We address the problem of suboptimal behavior caused by short horizons during online POMDP planning. Our solution extends potential-based reward shaping from the related field of reinforcement learning to online POMDP planning in order to improve planning without increasing the planning horizon. In our extension, information about the quality of belief(More)
In many real-world applications of multi-agent systems, agent reasoning suffers from bounded rationality caused by both limited resources and limited knowledge. When agent sensing to overcome its knowledge limitations also requires resource use, the agent’s knowledge refinement is affected due to its inability to always sense when and as accurately as(More)
especially helpful in large classrooms and in distance education. The instructor can also adjust a " highlight " threshold for each statistic such that any value failing to meet the threshold will be highlighted for easy observation. Our DatabaseSearch analysis tool allows students and teachers to search through recorded interactions and filter the results(More)
