This thesis explores student understanding of divergence in physics settings. The various uses of divergence in physics are detailed. Textbook approaches to divergence are categorized as geometric, curvilinear coordinate, discussion-based, and algebraic statement. Textbook approaches to the divergence theorem are categorized as geometric, equivalent integrals, mathematical statement with explanation, and...
In the past most research of family learning in informal science learning environments has included limited diversity among participants considering ethnic, cultural, and social economic status. The diversity seen in informal learning environments such as museums does not typically reflect that of the general population. Therefore, in order to foster...
This dissertation consists of a set of three manuscripts exploring features of effective professional development (PD) for science teacher educators. Literature about context-specific PD for science teacher educators is sparse. The first manuscript, a literature review, outlines theoretical lenses through which PD can be understood, the features of effective PD,...
This research is an exploration of empathy in the classroom from the standpoint of how instructors experience it and understand themselves to communicate it to their students, particularly students from different cultural backgrounds. The research method used was ethnographic analysis of a classroom observation and a one-hour semi-structured interview with...
A combination of theoretical perspectives is used to create a rich description of student reasoning when facing a highly-geometric electricity and magnetism problem in an upper-division active-engagement physics classroom at Oregon State University. Geometric reasoning as students encounter problem situations ranging from familiar to novel is described using van Zee...
On January 8th, 2011 tragedy struck in Tucson, Arizona. A gunman opened fire on Representative Gabrielle Giffords' "Congress on Your Corner" event, wounding thirteen and killing six ("Arizona Shooting"). Four days later, President Obama spoke to a grieving crowd at the University of Arizona's McKale Memorial Center. This study seeks...
This study investigates how teachers develop and extend their understanding and knowledge of teaching and learning with digital technologies in a primarily online Master of Science program. The investigation focuses on exploring the relationship between developing an online community of learners and the construction of technological pedagogical and content knowledge...
The purpose of this study was to detail mathematical knowledge that supports the work of teaching proof and to investigate how such knowledge is evidenced in professional development (PD). To advance the construct of mathematical knowledge for teaching (MKT) in the context of proof, I developed a framework of MKT...
An investigation was made to determine teacher facilitation techniques in large lecture physics classrooms that foster small group discussion. Video recordings of an introductory calculus-based physics class were taken for the 2008-2009 academic year at Oregon State University. These videos were analyzed to determine student participation in small group discussion...
The spreadsheet has become a common technology tool and is now a predominant form of end-user programming. Some of the same features that make spreadsheets excellent tools for ad-hoc development can introduce errors into the final product. Although a variety of research has been performed investigating methods to detect errors...
