Writing support for graduate students is one of the top concerns in the field of graduate writing education and research. The need of graduate writing support through communal writing practice opportunities has not been explored empirically yet. The main purpose of the study is to explore graduate student perception to develop and test a graduate…

Scientific collaboration networks are a special kind of social and communication networks in which nodes represents authors, and they are connected in pairs by an edge if they have worked together to publish a paper. Collaboration networks grow and change over time as new authors join the networks and new collaborative connections are formed…

This dissertation investigates the effect of observational learning in crowdsourcing markets as a lens to identify appropriate mechanism(s) for sustaining this increasingly popular business model. Observational learning occurs when crowdsourcing participating agents obtain knowledge from signals they observe in the marketplace and incorporate such…

Crowdsourcing is an emerging research area that has experienced rapid growth in the past few years. Although crowdsourcing has demonstrated its potential in numerous domains, several key challenges continue to hinder its application. One of the major challenges is quality control. How can crowdsourcing requesters effectively control the quality…

This dissertation presents a novel effort to develop ITS technologies that adapt by observing student behavior. In particular, we define an evolving expert knowledge base (EEKB) that structures a domain's information as a set of nodes and the relationships that exist between those nodes. The structure of this model is not the particularly novel…

Because MediaWiki is not appropriate for use in the classroom setting due to its decentralization, arbitrariness, and sharing, its flexible characteristics complicate concepts of practical design when applying MediaWiki in a mandatory writing context. This dissertation identifies a need to add extensions to facilitate increased accountability,…

The purpose of this study was to develop an instructional theory for using a class wiki to support collaborative learning in higher education. Although wikis have been identified in theory as one of the most powerful emerging technologies to support collaborative learning, challenges have been revealed in a number of studies regarding student…

Wikis have been gaining attention in the academic literature, suggesting their use as knowledge repositories in organizational environments and even as collaborative tools for reviewing scholar publications. And yet, little is known about factors that foster or discourage adoption of this technology. Taking elements from similar artifacts such as…
