Distributed collaboration over the Internet has become increasingly common in recent years, supported by various technologies such as virtual workspace systems. Often such collaboration is ad-hoc, and virtual workspaces are set up anew for each new instance of collaboration. We propose that much of the ad-hoc collaboration can be captured and transformed into patterns for reuse in future collaboration. This paper presents the results of the past five years of our work in this area. We introduce the notion of patterns of virtual collaboration;present a framework for extracting patterns of work in virtual workspace systems;and introduce an information model of virtual collaboration. We then present an overview of our data and process mining methods and reverse engineering techniques for discerning work processes carried out through virtual workspace systems. Finally we present our visual mining techniques that we use to discern aspects of work processes in virtual workspaces.

This paper describes an empirical study that investigates the knowledge that computer Science students have about the extent of their own previous learning. The study compares self-generated estimates of performance with actual performance on a data structures quiz taken by undergraduate students in courses requiring data structures as a pre-requisite. The study is contextualized and grounded within a research paradigm in Psychology called calibration of knowledge that suggests that self-knowledge across a range of disciplines is highly unreliable. Such self-knowledge is important because of its role in meta-cognition, particularly in cognitive self-regulation and monitoring. It is also important because of the credence that faculty give to student self-reports. Our results indicate that computer Science student self-estimates correlate moderately with their performance on a quiz, more so for estimates provided after they have taken the quiz than before. The pedagogical implications are that students should be provided with regular opportunities for empirical validation of their knowledge as well as being taught the metacognitive skills of regular self-testing in order to overcome validation bias.
