This qualitative study analyzed experiences of twenty software developers. The research showed that all software development methodologies are distinct from each other. While some, such as waterfall, focus on traditional, plan-driven approaches that allow software requirements and design to evolve; others facilitate ambiguity and uncertainty by…

American public school districts must deal with increased turnover and a shortage of qualified leadership due in part to the daunting responsibility associated with the increasingly complex role of the school principal. As more schools deal with difficulties associated with principal recruitment and retention, those qualities of effective leaders…

Public awareness of the severity of the high school completion problem in terms of its educational, social, psychological, and economic impacts has grown in recent years. Using ex post facto data, this non-experimental, correlational study was designed to determine whether there are differences in academic performance and school attendance between…

The goal of the dissertation study was to evaluate the existing DG scheduling algorithm. The evaluation was developed through previously explored simulated analyses of DGs performed by researchers in the field of DG scheduling optimization and to improve the current RT framework of the DG at TTU. The author analyzed the RT of an actual DG, thereby…

Although the "Rehabilitation Act of 1973" and the "Americans with Disabilities Act of 1990" have mandated the necessity of services for students with disabilities to receive equal access to education, a clear picture of what contributes to academic success is still lacking. Research indicates that students with disabilities…

School Climate has been identified by a large body of literature as having a direct relationship on student achievement (Johnson, & Stevens, 2000; Kezar & Eckel, 2007; West, 1985), and) and numerous other components used to determine the success and safety of both students and teachers in schools (Finnan, Schnepel, & Anderson, 2003;…

This supplement contains documentation on the explicit and implicit stratification variables included in the TIMSS 2011 data files. The explicit strata are smaller sampling frames, created from the national sampling frames, from which national samples of schools were drawn. The implicit strata are nested within the explicit strata, and were used…

The affordability of a degree from a public university is the subject of much heated debate in the halls of many state governments. The taxpayer, as well as the individual paying tuition, is asking the question: What is the return on investment for the millions of dollars used to support public higher education? The taxpayer views public…

The past decade has witnessed renewed interest in the use of the Johnson-Neyman (J-N) technique for calculating the regions of significance for the simple slope of a focal predictor on an outcome variable across the range of a second, continuous independent variable. Although tools have been developed to apply this technique to probe 2- and 3-way…

Latent class analysis was used to examine the career preparation of 5,227 11th-grade Korean adolescents taken from the Korean Education Longitudinal Study of 2005 (KELS:2005). Three career preparedness groups were identified, to reflecting Skorikov's ("J Vocat Behav" 70:8-24, 2007) conceptualization of career preparedness: prepared,…

For decades, (going back to the 1950s) the negative attitudes students hold towards salespeople and sales careers have been of concern to university educators and to employers seeking to recruit well-trained sales people. While the increasing demand for university educated salespeople continues to grow, employers are struggling to meet that…

Our project is motivated by the early dropout and low completion rate problem in MOOCs. We have extended traditional features for MOOC analysis with richer and higher granularity information to make more accurate predictions of dropout and performance. The results show that finer-grained temporal information increases the predictive power in the…

There is little doubt that career experiences contribute to scientific achievement; however this relationship has yet to be thoroughly investigated in terms the effects on scientific creativity. In this study, a historiometric approach was used to examine 3 areas of adult career experiences common to scientific achievement. In doing so, prior…

No scales currently exist that measure variability in the insight experience. Two scales were created to measure two factors hypothesized to be key drivers of the insight experience: insight radicality (i.e., perceived deviation between previous and new problem representations) and restructuring experience (i.e., the subjective experience of the…

This study evaluated the psychometric properties of two measures of student engagement, the Student Engagement Instrument (SEI) and the Motivation-Engagement Scale (MES), with adolescents in the southeastern United States. Confirmatory factor analyses revealed an acceptable fit of the SEI and a relatively poor fit of the MES in this sample.…
