Abstract: How do we measure knowledge sharing in an online collaborative website? This presentation explores how indicators of knowledge sharing in online communities can be identified, measured, and analyzed. Our goal is to improve understanding of the affordances of electronic communities as learning contexts. This presentation will demonstrate how techniques used to measure knowledge transfer and knowledge generation in online business communities can be applied to evaluation of educational virtual communities. The context for this evaluation is a STEM education online community that offers both public and private collaborative groups. The presentation will provide examples of strategies and contextual factors that show genuine knowledge sharing. The authors will present their results visually—showing the online context, case examples, data coding scheme, data summary system, visual representation of results, visual organizer depicting successful strategies, and contexts for future evaluation to further test the guidelines presented. #2012Conference #Ruberg #Piecka #STEMEducationandTraining #Collaborative,ParticipatoryandEmpowermentEval #Good
