This paper focuses on the development of a model of research and professional development which aims to bring about transformations in classroom practice in situations that have previously proved resistant to change. We explore reasons why conventional models have failed to address one such situation, the continuing predominance of teacher-centred…

Research interest in numeracy is growing as a result of increased understanding of the impact of low levels of numeracy. However, there has been little research on factors that influence how teachers implement learning from professional development interventions to support teachers to promote numeracy learning. This paper reports on how a…

This article presents a theoretical model of lesson study's impact on instruction, through intervening impact on teachers' knowledge, beliefs and dispositions, teachers' learning community, and curriculum. It also describes four different types of lesson study in Japan, pointing out their synergies in producing a system where local teachers…

The rationale for the introduction of standards in the United States in the late 1980s was that the quality of education would improve. Assessment instruments in the form of written tests were constructed in order to perform a monitoring function. The introduction of standards and the associated monitoring have been replicated in South Africa. It…

This paper presents the development process of a "praxeology" (theory-of-practice) for supporting the teaching of proofs in a CAS environment. The characteristics of the praxeology were elaborated within the frame of a professional development course for teaching analytic geometry with CAS. The theoretical framework draws on Chevallard's…

This study identified qualities of influential facilitators of elementary mathematics professional development. Extensive research relating to elementary mathematics professional development has emerged over the past three decades. Embedded in this body of research are recommendations for effective practices in professional development and…

Professional development (PD) is key to improving mathematics teaching and learning in the middle grades. Many PD projects and initiatives have been undertaken across the United States. Yet, we know very little about what teachers learn in and through such PD, nor about what those who conduct the PD might be learning as well. This knowledge gap…

Defining what teachers need to know to teach algebra successfully is important for informing teacher preparation and professional development efforts. Based on prior research, analysis of video, interviews with teachers, and analysis of textbooks, we define categories of knowledge and practices of teaching for understanding and assessing teachers'…

In this article, we describe a conceptual framework for in-service professional development--the Whole Teacher approach. A significant departure from the traditional approach to professional development that speaks primarily to teachers' acquisition of knowledge and skills, the Whole Teacher framework emphasizes promoting all aspects of a…

Though it is widely acknowledged that teachers' knowledge of mathematics is a cornerstone on which their instructional practices are based, little research exists documenting the impact of changes in teachers' mathematical content knowledge on their teaching practices. As proving is a central activity in the study of mathematics, a teacher's proof…

This study sought to understand the process of change elementary teachers experienced as they participated in mathematics professional development. This investigation explored the impact of mathematics professional development on teachers' content knowledge for teaching, their ability to implement innovative pedagogical practices, and the…

An exploratory quantitative study of professional learning communities and student achievement in the largest school system in the State of North Carolina provides evidence to support systemic implementation of professional learning community practices and activities. A one-way ANOVA was conducted to explore the impact of teachers' perceptions of…

The purpose of this Executive Position Paper is to examine the ways in which teachers learn to implement a new mathematics curriculum. The four case study teachers described in this paper were in their first and second year of teaching the "Investigations" curriculum. In the course of learning to teach with "Investigations," the teachers were…

The design and implementation of the professional development model of the New Zealand Numeracy Development Project has been successful in improving teacher knowledge and practice as well as raising student outcomes. Since 2000, more than 25,000 teachers in English-medium settings have participated in the project. In New Zealand the terms…

Trends in International Mathematics and Science Study raised the concern that the United States (US) mathematics teachers place less emphasis on topics and teach a variety of content strands (Goldsmith, Mark & Kantrov, 2000; Kerachsky, 2008). The overall pattern in the US mathematics classrooms today is that primary and upper elementary…
