A Framework for Asynchronous Collaborative Learning and Problem Solving

Research has shown that classroom learning improves significantly when a student participates in learning activities with small groups of peers. This educational value of student collaboration has led to the development of computer-supported collaborative learning (CSCL) tools. These tools enrich learning in a setting that encourages students to communicate with their peers. In typical web-based collaborative learning environments, however, it is not always possible for all learners to gather and participate in a learning activity at the same time. Asynchronous and not just synchronous learning must be addressed. In this paper a framework to provide rich asynchronous services to web-based students is described. A key component of this environment is the use of replay to enhance asynchronous learning. Replay provides persistence of objects and actions over time.
