The aim of the study reported in this paper was to explore and enhance experienced school mathematics teachers' knowledge of students'thinking, as it is manifested in practice. Data were collected from records of classroom observations, interviews with participating teachers, and weekly teacher-researcher meetings organized in the school. In this…

Over the last decade, researchers have investigated the nature and scope of mathematical knowledge for teaching (MKT) and have provided evidence that teachers' MKT plays a critical role in the effectiveness of teaching and learning. This dissertation focuses on the problem of helping teachers develop MKT. Two goals shape the research: (1) to…

This study of six teachers focuses on the ways they organized the classroom discourse, attended to student thinking, and adapted complex tasks from a Standard-based middle school curriculum. The study explores Cohen's (2011) premise that the knowledge teachers develop is related to their attentiveness to student teaching. This study explores the…

As curriculum scholars in South Africa express concerns about the failures of the outcomes-based curriculum policy that has been introduced post-apartheid it is of increased importance to try and understand the professional development that is required by teachers for its successful implementation. As a contribution to the development of such…

This article presents results from a case study analyzing the process of change for early childhood educators as they engage in a semester-long professional development (PD) experience focused on developing a teacher research agenda related to mathematics instruction. During this PD experience, 11 participants (5 second-grade and 6 third-grade…

For the past decade, students at California State University (CSU) campuses increasingly lack basic mathematics skills. To address this concern, Executive Order No. 665 (1998) called for CSU campuses to bring students to proficiency in mathematics. School districts have struggled to modify their mathematics curriculum, pedagogy, and assessment in…

This issue of the Center's "Systems Newsletter" will be the last one published under the aegis of Dr. JoyceVanTassel-Baska, the Center's founder and current Executive Director. As of this August Dr. VanTassel-Baska will officially retire from the College of William and Mary and the Center. She will still be an integral part of the Center…

Considers the professional life histories of two Brazilian mathematics teachers in the context of mandated curriculum change, identifying changes in thought and practice and noting experiences that influenced change. Reflection on their own thought and practice, and interest in their own development, were the most important internal aspects…

Drawing inspiration from Shulman's (1986) construct of pedagogical content knowledge, we propose that leadership content knowledge is a missing paradigm in the analysis of school and district leadership. After defining leadership content knowledge as that knowledge of academic subjects that is used by administrators when they function as…

Teacher preparation programs are in danger of seriously under-preparing elementary teachers to teach mathematics for understanding if they wait to provide students with evidence of effective mathematics teaching methods in the mathematics methods courses. With strong traditional beliefs about how mathematics ought to be taught and their…
