The purpose of this quantitative correlational study was to explore the relationships between the independent variables, contextual factors for virtual teams and collaboration technology, and the dependent variable, virtual project outcomes. The problem leading to the need for the study is a lower success rate for virtual projects compared to…

Consistent with a recognized challenge across the United States, the local problem addressed in this study was teachers' inability to implement new technologies in the classroom. Professional development is the channel through which teachers improve, and high-quality professional development has been shown to enhance teacher efficacy. Professional…

In this investigation, we examined the extent to which instructional expenditures were related to student academic achievement for students enrolled in Texas public schools for the 2005-2006 through the 2009-2010 school years. Student performance on the state-mandated assessments for all school districts in Texas for these five school years was…

Khan Academy is a large and popular open educational resource (OER) with little empirical study into its impact on student achievement in mathematics when used in schools. In this study, we examined the use of Khan Academy as a mathematics intervention among seventh grade students over a 4-week period versus a control group. We also compared…

The purpose of this quantitative correlational study was to examine the relationship between college experience at a HBCU and students' critical thinking skills. The theoretical framework included Astin's theory of involvement and Facione's taxonomy of critical thinking. The research site was a private four-year HBCU in the state of Alabama. The…

Research indicates the primary difference between strong and weak readers is their phonemic awareness skills. However, there is no consensus regarding which specific components of phonemic awareness contribute most robustly to reading comprehension. In this study, the relationship among sound blending, sound segmentation, and reading comprehension…

This research focuses on ePortfolio assessment strategies that yield important accountability and reporting information.

Three-dimensional thinking skills are extremely useful for geoscientists, and at the undergraduate level, these skills are often emphasized in structural geology courses. Google Earth is a powerful tool for visualizing the three-dimensional nature of data collected on the surface of Earth. The results of a 5 y pre- and posttest study of the…

The identification of evidence-based practices continues to provoke issues of disagreement across multiple fields. One area of contention is the role of single-subject design (SSD) research in providing scientific evidence. The debate about SSD's utility centers on three issues: sample size, effect size, and serial dependence. One potential…

In order to circumvent the influence of correlation in paired-samples and repeated measures experimental designs, researchers typically perform a one-sample Student "t" test on difference scores. That procedure entails some loss of power, because it employs N - 1 degrees of freedom instead of the 2N - 2 degrees of freedom of the…

In this study, pre-service science teachers' anxiety, self-efficacy and attitudes regarding educational technology were investigated. Given the increased emphasis on educational technology in the classroom, teachers' attitudes, anxiety and self-efficacy regarding educational technology are important.
