Rodent Effects On Shrubs In A Mojave Desert Shrub Community, Steven Schuyler Vrooman
UNLV Retrospective Theses & Dissertations

Building Community In A Virtual Classroom: Construction Of Classroom Culture In A Postsecondary Distance Education Class, Virginia Anne Bielman
UNLV Retrospective Theses & Dissertations
The purpose of this dissertation was to investigate how a community was constructed in a postsecondary distance education class that relied only on computer-mediated communications. The use of a social constructionist perspective with Interactional Ethnography provided a theoretical and methodological means to make visible how the actions and interactions of the class members constructed their community. This study was built on and expanded qualitative research in K--12 traditional classrooms, which provided a lens with which to view the processes that shaped on-line community development. Past research has used ethnography and discourse analysis to investigate how traditional classroom participants' interactions over …
