Are there any differences in outcomes between traditional classroom-based university courses and courses delivered via Asynchronous Learning Networks (ALN?) Under what conditions are ALN courses most effective? What can be done to improve the publishability of ALN evaluations, and counter the attacks of critics? After providing background on the NJIT(More)
This paper puts forth a vision and an architecture for a community knowledge evolution system. We propose augmenting a multimedia document repository (digital library) with innovative knowledge evolution support, including computermediated communications, community process support, decision support, advanced hypermedia features, and conceptual knowledge(More)
