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 computersupported collaborative learning (CSCL) tools. These tools enrich learning in a setting that encourages students to communicate with their peers. In typical webbased 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.
