Teaching mathematics requires a wide range of knowledge, including types of mathematical knowledge specialized to the work of teaching. Because specialized content knowledge is a form of professional knowledge, it is important to emphasize in professional preparation. In this paper, we present results comparing the performance of prospective and…

Teacher professional development (PD) is seen as a promising intervention to improve teacher knowledge, instructional practice, and ultimately student learning. While research finds instances of significant program effects on teacher knowledge, little is known about how long these effects last. If teachers forget what is learned, the contribution…

The primary purpose of this report is to provide preliminary evidence on the measurement properties for newly designed assessments of content knowledge for teaching (CKT) in elementary reading language arts (RLA) and mathematics. The goal is to offer the CKT tests through the "PRAXIS"® assessment. Additional analyses were conducted to…

Assessments of teacher content knowledge are increasingly designed to provide evidence of the content knowledge needed to carry out the moment-to-moment work of teaching. Often these assessments focus on content knowledge only used in teaching with the goal of testing types of professional content knowledge. In this paper, we argue that while this…

Research into teacher learning and practice over the last three decades shows that the teachers of a specific subject need to possess knowledge that is different from the knowledge of other content experts. Yet this specialized version of content knowledge that teachers need to plan instruction, respond to student ideas, and assess student…

This report documents the development of assessments of content knowledge for teaching (CKT) as part of the Measures of Effective Teaching (MET) study, funded by the Bill and Melinda Gates Foundation.The MET study was designed to develop a set of measures that together serve as an accurate indicator of teaching effectiveness. The study was…

Despite recent shifts in research emphasizing the value of carefully designed experiments, the number of studies of teacher professional development with rigorous designs has lagged behind its student outcome counterparts. We outline a framework for the design of group randomized trials (GRTs) with teachers' knowledge as the outcome and…

We examine the impact of teacher professional development on a key aspect of teacher quality--teacher knowledge. Specifically we use English Language Arts teacher content and pedagogy assessments to determine whether the California Professional Development Institutes significantly improve teacher content knowledge and whether teachers retain that…

With research indicating substantial differences among teachers in terms of their effectiveness (Nye, Konstantopoulous, & Hedges, 2004), a major focus of recent research in education has been on improving teacher quality through professional development (Desimone, 2009; Institute of Educations Sciences [IES], 2012; Measures of Effective…

This article reports the authors' efforts to develop a practice-based theory of content knowledge for teaching built on Shulman's (1986) notion of pedagogical content knowledge. As the concept of pedagogical content knowledge caught on, it was in need of theoretical development, analytic clarification, and empirical testing. The purpose of the…

The purpose of this study was to determine whether third-grade teachers' instructional actions during reading comprehension lessons contributed to their students' reading comprehension achievement. Our framework focused on teachers' emphasis on three dimensions of instruction (pedagogical structure, teacher-directed instruction, and support for…

Debates persist over the knowledge needed to teach elementary reading effectively. In one commonly held view verbal ability is what matters most and the best approach to improving teacher quality is to recruit teachers who themselves are good readers. Others argue that teachers need special forms of professional knowledge that differ substantially…

Our framework focused on teachers' emphasis on three dimensions of instruction (pedagogical structure, teacher-directed instruction, and support for…

In this article we present results from a project to develop survey measures of the content knowledge teachers need to teach elementary reading. In areas such as mathematics and science, there has been great interest in the specialized ways teachers need to know a subject to teach it to others -- often referred to as pedagogical content knowledge.…
