Social computational systems emerge in the wild on popular social networking sites like Facebook and Twitter, but there remains confusion about the relationship between social interactions and the technical traces of interaction left behind through use. Twitter interactions and social experience are particularly challenging to make sense of because of the(More)
A few studies have attempted to provide metrics of success in open source software (OSS) projects but the role a code hosting workspace plays in how performance is viewed and measured is little examined. We conducted qualitative, exploratory research with lead and core developers on three successful projects on GitHub to understand how OSS communities on(More)
Building a student performance prediction model that is both practical and understandable for users is a challenging task fraught with confounding factors to collect and measure. Most current prediction models are difficult for teachers to interpret. This poses significant problems for model use (e.g. personalizing education and intervention) as well as(More)
A 16-student, completely online software design course was studied using social network analysis and grounded theory techniques. Bi-directional (read and post) log data of user activity was recorded to understand how small group networks change over time with activity type (individual, peer-to-peer, and small group). Network structure was revealed through(More)
Purpose – This paper has two purposes. First, to provide insight into the formation of completely online small groups, paying special attention to how their work practices develop, and how they form identity. Second, to pursue conceptual development of a more multi-level view of completely online group experience, which can be made visible through analysis(More)

With this study we seek to provide an understanding of the discourse and agenda setting practices of an online issue based political group, "Join the Coffee Party Movement" (JCPM) in the United States. The stated goals of JCPM are to establish a place for individuals who identify themselves as disenfranchised to discuss and take action on issues of social(More)
The US Navy directed its vast resources at the relief effort following the Haiti Earthquake on January 12, 2010. To coordinate with non-governmental-organizations (NGOs) participating in the relief effort, the US Navy used an online discussion forum. What follows is an examination of the emergence, rise, on-the-ground utility and decline of this(More)
We describe a method for determining coordination requirements in collaborative software development. Our method uses "live" data based on developer activity rather than relying on historical data such as source code commits which is prevalent in existing methods. We introduce proximity, a measure of the strength of the work dependencies that lead to(More)
