By implementing the use of a case study as a qualitative research method, this study investigated why students dropped out for their distance education programs. The study group was composed of 25 students who had dropped out of distance…

Time dependence is of fundamental importance for the description of quantum systems, but is particularly difficult for students to master. We describe the development and evaluation of a combined simulation-tutorial to support the development of visual understanding of time dependence in quantum mechanics. The associated interactive simulation…

This study contributed to our understanding of those factors that serve as predictors of science teachers' selection and use of technologies and more specifically, how selection and usage was realized among teachers of different science disciplines. Notable descriptive statistics were examined, and we tested an explanatory model of how…

Using data from the Education Longitudinal Study of 2002, a nationally representative sample of US high school students, I investigate how features of secondary schools influence the likelihood of Latino students completing high school. To do so, I introduce the concept of school incorporation, which includes school policies, school receptivity…
