The authors conducted ethnographic research to provide deep understanding of the learning environment of a selection of computer science classrooms at a large, research university in the United States. Categories emerging from data analysis included (1) impersonal environment and guarded behavior; and (2) the creation and maintenance of informal hierarchy(More)
This paper describes an exploratory study to identify which environmental and student factors best predict intention to persist in the computer science major. The findings can be used to make decisions about initiatives for increasing retention. Eight indices of student characteristics and perceptions were developed using the research-based Student(More)
Undergraduate research experiences are promoted and funded for their potential in increasing students’ likelihood of pursuing graduate degrees, increasing their confidence, and expanding their awareness of their discipline and career opportunities. These outcomes, however, depend on the social, organizational, and intellectual conditions under which(More)
All learning environments are characterized by numerous communication and interaction practices, which lend themselves to an overall characterization of the climate as defensive or supportive. A case study of public communication and interaction in a large, research-intensive university's first year computer science courses illustrates a learning(More)
A three-part study of teachers' use of online resources and of the Digital Library for Earth System Education (DLESE) was conducted from 2004 through summer 2006. The first two phases were qualitative and informed a survey administered to 622 science teachers across the U.S., one-fifth of whom had used DLESE. The findings present a profile of teachers and(More)
As part of an NSF-funded IT Workforce grant, the authors conducted ethnographic research to provide deep understanding of the learning environment of computer science classrooms. Categories emerging from data analysis included 1) impersonal environment and guarded behavior; and 2) the creation and maintenance of informal hierarchy resulting in competitive(More)
This paper presents a case study as a "cautionary tale" to faculty, demonstrating how students and instructors often perceive pressure to finish projects for clients. As a result of this pressure, and because students generally lacked any understanding of how to work well in groups, students selected their roles based on expediency or familiarity. This(More)
This panel will discuss the enrollment boom, as well as potential effective practice strategies to respond to the increasing demand for computing education. Does the current enrollment "boom" represent the "third bubble", or is it here to stay? Is there a difference in what's happening at universities that offer Ph.D. degrees or what's happening at 4-year(More)
