Secondary Preservice Teachers' Understanding Of Euclidean Geometry, Karen Sabey
Secondary Preservice Teachers' Understanding Of Euclidean Geometry, Karen Sabey
Dissertations and Theses @ UNI
The lack of mathematical understanding of elementary preservice teachers with respect to many mathematical topics has been well documented. Far fewer studies have been conducted on any content area of knowledge of secondary teachers and even less in the mathematics content area. The assumption by the general population is that mathematics majors are adequately prepared to teach the content of secondary mathematics because they major in mathematics. Mathematics educators, however, note the lack of conceptual understandings in many content areas in these mathematics teaching majors. While mathematics educators are aware of this deficiency, there is little research data at the …
The Third Space: The Use Of Self-Study To Examine The Culture Of A Science Classroom, Dashia M. Magee
The Third Space: The Use Of Self-Study To Examine The Culture Of A Science Classroom, Dashia M. Magee
Dissertations and Theses @ UNI
Science educators are in the position to create bridges between their students and the world of science (Aikenhead, 1996, 1999). This connection has often been described as the third space (Bhabha, 1994; Moje, Collazo, Carrillo, & Marx, 2001; Wallace, 2004), which is represented as a combination or a meeting of the students' world and the world of science. In this study, I examined my role in creating the third space through the use of self-study. Self-study is a form of research, educators use to understand their practice (Austin & Senese, 2004; Loughran, 2004; Northfield & Loughran, 1996). It is a …

Algebra Rules Object Boxes As An Authentic Assessment Task Of Preservice Elementary Teacher Learning In A Mathematics Methods Course, Audrey C. Rule, J. E. Hallagan
Open Educational Resources
The purpose of this study was to describe elementary preservice teachers’ difficulties with understanding algebraic generalizations that were set in an authentic context. Fifty-eight preservice teachers enrolled in an elementary mathematics methods course participated in the study. These students explored and practiced with authentic, hands-on materials called “object boxes,” then created sets of their own object box materials. Each algebra rules object box contained materials to illustrate and describe four different algebraic generalizations, or “rules.” The variables “n” and “z” were used in each of the generalizations. For each generalization, there was a set of objects attached to a piece …
