A professional development program (PSPD) was implemented to improve in-service secondary mathematics teachers' content knowledge, pedagogical knowledge, and self-efficacy in teaching secondary school statistics and probability. Participants generated a teaching resource website at the conclusion of the PSPD program. Participants' content…

This dissertation study focuses on a current and controversial phenomenon in Chinese universities and colleges--student working during academic semesters. The massification of Chinese higher education since the year of 1999 raises the level of competition in the job market of college graduates. More and more undergraduate students participate in…

The difficulties introductory statistics students have with formal statistical inference are well known in the field of statistics education. "Informal" statistical inference has been studied as a means to introduce inferential reasoning well before and without the formalities of formal statistical inference. This mixed methods study…

Stochastic understanding of probability distribution undergirds development of conceptual connections between probability and statistics and supports development of a principled understanding of statistical inference. This study investigated the impact of an instructional course intervention designed to support development of stochastic…

Organizations work towards achieving their goals by integrating and utilizing the knowledge available within their boundaries. In order to successfully manage the knowledge-related processes occurring in their workgroups, organizations need to understand how different contingency factors affect the knowledge-related processes of a workgroup,…

Sociological literature has not paid the same attention to the educational attainment of lesbian, gay, and bisexual (LGB) persons, despite their status as a socially marginalized group. Through the application of sociological methods and theories, my dissertation argues that sexual identity's effect on educational attainment is…

As the reauthorization of NCLB looms on the horizon, many states have made the decision to re-evaluate the teacher role in the classroom as it relates to student achievement. The accountability era in public education has evolved over the last decade to encompass broad changes, some good, some questionable. In education it takes time determine the…

This mixed-methodological study explored the factors that predict a student's likelihood to complete an undergraduate program in a STEM discipline at one campus reliant upon that mission. Offered in response to a national imperative for the U.S. to compete globally, researchers contend educators must better prepare a STEM foundation and inspire…

The purposes of this study were to investigate preservice mathematics teachers' orientations, content knowledge, and pedagogical content knowledge of probability; the relationships among these three aspects; and the usefulness of tasks with respect to examining these aspects of knowledge. The design of the study was a multi-case study of five…
