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)
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)
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)
"So far, evaluation has not kept pace with efforts in digital libraries (or with digital libraries themselves), has not become part of their integral activity, and has not been even specified as to what it means, and how to do it." - [1]Conducting a comprehensive evaluation of a digital library requires a "triangulation" approach including multiple models,(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)
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)
Two pedagogical techniques of IT programs are compared, a traditionally taught computer science (CS) major and an IT certificate program using a fine arts approach to pedagogy. The latter graduates a higher percentage of women than of males. Although the two programs are quite different in the nature of the material and what students are expected to learn,(More)
