This study examines teacher's perspectives of the most beneficial professional development they have participated in over the last three years in the content areas of literacy and mathematics. It also investigates teachers views on how professional development influences student learning. Specifically, this study is grounded in the following…

The purpose of this article is to explore the usefulness of a video-based tool for measuring teachers' mathematical knowledge for teaching. Unique to this tool is the use of a video featuring a mathematical disagreement that occurred in an elementary classroom. The authors define mathematical disagreements as instances in which students challenge…

Although preparing teachers to be leaders is a common goal of teacher education programs, often "teaching" and "leading" are located in separate departments" (Mangin & Stoelinga, 2009, p. 56). Recently, however, the assessment of teacher leadership has become important in preservice teacher education. This importance…

The racial/ethnic populations in public schools have changed dramatically in recent years and will continue to shift to a majority non-White population. The National Center for Education Statistics (2010) reports 67.3% of the student population in urban districts is composed of students of color. Yet, the population of teachers in the United…

This study aims to begin to uncover the detailed ways that pre-service elementary teachers examine and understand mathematics teaching, the grain size at which they do so, and what constitutes evidence of teaching mathematics for understanding for pre-service mathematics teachers. Thus, the central research questions for this study are: (a) What…

Elementary school children in the United States are not developing acceptable levels of mathematical proficiency (National Center for Education Statistics, 1999), and a major concern of teacher educators is that teachers lack the depth and flexibility of mathematical understanding and the corresponding beliefs they need to teach for proficiency…

Elementary school mathematics teaching begins with the teacher's understanding of the mathematical content to be taught. The teacher knows how to "do" the mathematics, i. e., understands the concepts and truths concerning that mathematics. The teacher then decides how to present the mathematics. Based on the students' background in mathematics,…

In this paper, the author presents a study which explored K-8 preservice teachers' concept images and mathematical definitions of polygons. This study was carried out in which K-8 teacher candidates enrolled in an elementary mathematics content course were asked to sort, identify, and provide definitions of such shapes including triangles,…
