Many authors recommend various praise to reprimand ratios for teachers to use to manage their classrooms (e.g., Flora, 2000; Nafpaktitis, Mayer, & Butterworth, 1985; Wheldall, 2005); however, these recommendations are based on correlational data or secondary findings from studies not directly manipulating the praise to reprimand ratio. The purpose…

In the state of Georgia, African Americans represent 38% of the student population, yet they account for more than half of the grade level retentions each year (The Governor's Office of Student Achievement, 2009). The purpose of this study was to determine if relationships exist between the disproportionate retention rate of African American…

Virtual worlds provide useful platforms for social behavioral research, but impose stringent limitations on the rules of engagement, responsiveness, and data collection, along with other resource restrictions. The major challenge from a computer science standpoint in developing group behavior applications for such environments is accommodating the…

The recent decision handed down by the U.S. Supreme Court in "Parents Involved in Community Schools v. Seattle School District No. 1" (2007) has forced school districts to begin thinking of new ways to integrate their schools without relying on race as the single factor in their assignment plans. While some school districts already have begun to…

Closed domain question answering (QA) systems achieve precision and recall at the cost of complex language processing techniques to parse the answer corpus. We propose a "query-based" model for indexing answers in a closed domain factoid QA system. Further, we use a phrase term inference method for improving the ranking order of related questions.…

Scope and method of study: Using Mary Douglas' (1982) Grid and Group Typology, the purpose of this case study was to explain the distinctive patterns of student engagement, communication and community in the culture of four online courses. The participants were four online instructors and four of their students who completed online courses at…

Despite the potential value of leveraging organizational memory and expertise, small organizations have been unable to capitalize on its promised value. Existing solutions have largely side-stepped the unique needs of these organizations, which are relegated to systems designed to take advantage of large pools of experts or to use Internet sources…

Widespread and continuous spatial and temporal environmental data is essential for effective environmental monitoring, sustainable natural resource management, and ecologically responsible decisions. Our environmental monitoring, data management and reporting enterprise is not matched to current problems, concerns, and decision-making needs.…

Many studies examine the impact of students' characteristics and behaviors on high school outcomes: high school completion, college enrollment or college completion. This study uses regression analyses to explore the association of students' characteristics and behaviors and students' positive high school outcomes: graduating on-time, enrolling in…

The primary purpose of this study was to design and validate a measure of teacher knowledge of Universal Design for Assessment (TK-UDA). Guided by a validity framework, a number of inferences, assumptions, and evidences supported this investigation. By addressing a series of research questions, evidence was garnered for the use of the measure to…

More faculty report each year that they are incorporating service-learning in their academic courses, which is often related to attempts by colleges and universities to link academics with service to the community as part of their mission, or by the academic disciplines that see service-learning as a way to link theory and practice. Critical to…

Scope and method of study: The purpose of this study was to investigate the determinants of mobile learning acceptance in higher education. Mobile learning is a rapidly growing method of learning that utilizes mobile devices to deliver content. Acceptance of mobile learning theory was derived from technology acceptance theories. The study…

This research attempted to determine variables predictive of success in mathematics achievement among pre-service teachers at UMKC. It was conducted during the Winter 2006 semester at a medium-sized urban university. The participants (all students enrolled in geometry courses) were invited to volunteer; 49 agreed to participate. Three structured…

Over the past several years, educational leaders and researchers have tried to find the causes for high school dropout. Studies have shown that both demographic and student factors have contributed to placing a student at risk for dropping out of high school. Most of the studies, however, have been conducted in urban or suburban settings.…

Previous research implementing stratification on the propensity score has generally relied on using five strata, based on prior theoretical groundwork and minimal empirical evidence as to the suitability of quintiles to adequately reduce bias in all cases and across all sample sizes. This study investigates bias reduction across varying number of…
