[Teachers] have no time to work with or observe other teachers; they experience occasional hit-and-run workshops that are usually unconnected to their work and immediate problems of practice. [Effective professional development cannot] be adequately cultivated without the development of more substantial professional discourse and engagement in communities(More)
K-12 education reform research suggests that new models of teacher professional development (TPD) are needed to establish and support communities of teachers engaged in school reform. We are working with several TPD organizations to develop a new on-line TPD community concept called TAPPED IN. Together, we are forging what we believe will be a(More)
In a prior issue of Technology and Society [1], McFarland argues that we should not view the Internet as a superhighway, but rather as a gathering place, or agora, that " brings people together, encourages participation, and supports creativity, " a place that is " always growing, adapting, and changing in response to new ideas and initiatives. " We agree(More)
TAPPED IN is an on-line teacher professional development (TPD) research testbed designed to meet the needs of a large and diverse community of education professionals. The MOO technology that supports the testbed has demonstrated sustainability, usability, desirability, and utility across a wide-rage of activities and users. However, we are quickly coming(More)
We argue that new frameworks, tools, and techniques are needed to understand and maximize the benefits of emerging online social networks of K-12 educators (and students). We base our argument on conceptual and methodological obstacles inherent in existing research approaches that severely limit theory building and empirical exploration of learning in(More)

Abstract Socio-technical networks that are heterogeneous in composition of actors and the media through which they interact are becoming common, but opportunities to study the emergent community structure of such networks are rare. We report a study of an international(More)
We have developed a set of analytic tools to identify and develop virtual environment (VE) simulation training applications. Task selection criteria help identify tasks that might benefit from VE training; VE requirements matrices are used to derive VE training system requirements; and cost-effectiveness factors are used to judge the relative merits of VE(More)
