We posit that professional development (PD) models fall on a continuum from highly adaptive to highly specified, and that these constructs provide a productive way to characterize and distinguish among models. The study reported here examines the impact of an adaptive mathematics PD model on teachers' knowledge and instructional practices as…

Recent research on teacher professional development (PD) underscores the importance of the coherence of PD with standards, curriculum, and assessment. Teachers' judgments of the coherence of PD with larger system goals influence their decisions about what ideas and resources they appropriate from PD. Little research, however, has examined how…

Amid calls for more practice-based teacher education, this article presents a concrete illustration of a practice-based bridging strategy for preparing high school biology teachers to enact open-inquiry labs. Open-inquiry labs were considered a core practice frame that served as a context for identifying core practices and for giving coherence to…

Increasingly, teacher leadership is being recognized as an essential ingredient in education reforms; however, few teachers consider themselves leaders. Becoming a leader is not just acquiring knowledge and skills for leadership, but developing a new "professional identity." As teachers become leaders, however, this identity might put…

Video is being used more widely in professional development to help teachers learn to notice and systematically analyze teaching practice. Video captures the authenticity and complexity of teaching and can promote the examination of classroom interactions in a deliberate and focused way. However, simply viewing video does not ensure teacher…

Teacher preparation programs commonly use observational instruments to assess the progress and the exit performances of teacher candidates. However, while these instruments have been described and several have been studied for effectiveness, the field lacks a close examination of how they position participants: teacher candidates, K-12 pupils, and…

In this investigation, we assessed 443 teachers' beliefs with the "Teaching Ability Belief Scale" (TABS) and the "Importance of Teaching Knowledge Scale" (ITKS). Using cluster analysis, we identified four groups of teachers based on their responses to the TABS reflecting "Innate," "Learned,"…

The edTPA, a nationally available performance assessment for teacher candidates, has recently been developed and implemented in teacher education programs across the United States. Advocates make arguments for the need for such an assessment while critics of standardized performance assessments point out the dangers of standardization. This…

As classrooms have increasingly become diverse and complex, developing culturally responsive pedagogies is a professional imperative for teachers. However, considerable international research suggests that meeting the needs of diverse pupil cohorts is challenging for many teachers. In this article, we highlight how curriculum and teaching…

At a time when teacher training is being moved to school-based programmes it is important to engage in a research-informed dialogue about creating more distinctive, and cost-effective 21st century models of teacher training. Three years ago I began feasibility field testing the Lesson Observation On-line (Evidence Portfolio) Platform [LOOP]…

Despite pressing concerns about the need to prepare high-quality teachers and the central role of teacher educators (TEs) in this process, little is known about how TEs teach about teaching specific subject matter, and how they develop their expertise. This empirical study focuses on the specific expertise that science TEs bring into teacher…

This study employed a randomized experiment to examine differences in teacher and student learning from professional development (PD) in two modalities: online and face-to-face. The study explores whether there are differences in teacher knowledge and beliefs, teacher classroom practice, and student learning outcomes related to PD modality.…

Mentors play a key role in developing preservice teachers for their chosen careers, and providing feedback appears as a significant relational interaction between the mentor and mentee that assists in guiding the mentee's practices. But what are mentors' perspectives on providing feedback to their mentees? In this case study, eight…

This article explores pre-service and in-service science teachers' perceptions on active learning, and examines the effectiveness of active learning by pre-service science teachers in the Irish second level classroom through a two-phase study. In the first phase, data on perceptions were gathered from final year pre-service teachers and…

This article reports the findings of a PhD study, which offers comparative perspectives on teacher education in a period of reforms, inquiring into stakeholders' perceptions in English, French, Italian and Spanish contexts as case studies. The interaction of needs and constraints in European initial teacher education within higher education…
