The main goal of the Learning and Teaching Geometry project is to build professional development materials that provide opportunities for teachers to learn about mathematical similarity through the use of videocases, in which specific and increasingly complex mathematical ideas are presented within the dynamics of classroom practice. The central…

A professional development program for US teachers in the state of Oregon was the context in which this study took place. This five-year hybrid (online and face-to-face) program assisted experienced teachers to adapt their practice to meet the needs of language minority and immigrant students. The positive changes in teacher perceptions and…

This study examines an embedded professional development practice for secondary teachers, namely peer-to-peer observations (P2POs). P2POs involve teachers identifying goals and watching colleagues teach in order to expand their knowledge, practice and pedagogy. The research questions addressed are: what are teachers' experiences with P2POs,…

This paper offers a conceptual model and rich narratives that describe the contexts in which teacher leadership emerges and the many ways that leadership is enacted. Drawing on qualitative case studies of seven Maine, USA schools, the authors found that teachers initiated their own professional learning efforts with the central goal of improving…

This two-year study examines an emergent model for promoting classroom change amidst systemic professional development efforts--the hybrid teacher leader (HTL). Utilizing ecological and teacher social network frameworks, the relative strengths and weaknesses of educators who both teach and lead teachers are explored. In-depth qualitative data from…

Professional learning to embed educational reform may need to take account of the stage of the reform rather than previous teaching experience.

In 2007, the New Zealand Ministry…

In this article we portray our personal journeys in a cross-cultural context resulting in professional growth. Data are presented in the form of constructed dialogues, and are reflected upon using the theories of transformative learning and intercultural competency. The role of lesson study as a vehicle for our journeys is examined. Reflection on…

This study examines professional development activities provided for mathematics and science teachers in the National Science Foundation's Math and Science Partnership Program by analyzing a cross-sectional sample of over 2000 professional development (PD) activities in the program. Data were gathered from secondary source documents and surveys to…

This paper provides a detailed description and evaluation of a three-year professional development project in a large urban setting in the southwestern United States.

A comparative review of the research literature regarding the effectiveness of continuing professional development (CPD) demonstrates that a range of different factors needs to be present if it is to have impact in the classroom and that short CPD episodes are unlikely to be effective. The Earth Science Education Unit approach to CPD had to be…
