Background: Collaboration among teachers is now considered a marker of effective schools and key to creating successful professional learning opportunities. However, the nature and efficacy of collaboration vary widely, and research suggests that collaborative efforts often fail to promote teacher development. Purpose: This study draws on…

Background: Research-practice partnerships (RPPs) are proliferating in education, generating increasing interest and posing many challenges. In this study, we shed light on the challenge of supporting practitioners' leadership and building capacity in an RPP. In the RPP literature, practitioner leadership is often highlighted as both a way to…

Background/Context: Continuous improvement methods are becoming increasingly popular in education. Existing research has emphasized the technical aspects of improvement practice and has rarely focused on important social phenomena that underlie improvement work, such as the mindsets and identities of successful practitioners. To address this gap,…

Background/Context: While current research provides key insights about successful collaboration in which teachers experience deep learning and practice change, few studies analyze the content of teachers' collaborative conversations about instruction. Even fewer explore how the content of collaborative conversations evolves over time, making it…

Background: Mathematics education is not often identified as the locus of radical social change work, with these topics assumed instead as fodder for social studies or language arts lessons. As such, teachers of mathematics can struggle to find avenues for their commitments to social and educational justice in their mathematics teaching spaces.…

Background: Alternatively certified (AC) teachers have generally been found to turn over at higher rates than traditionally certified (TC) teachers. These higher turnover rates are generally attributed to lower levels of preparedness and less of a commitment to remain in teaching than TC teachers, both of which may be compounded by AC teachers'…

Background/Context: Many urban schools today look to instructional teams as a means to decrease professional isolation, promote teachers' ongoing development, and substantially reduce well-documented variation in teachers' effectiveness across classrooms. Recent research finds that teams can contribute to teachers' development and increased…

Background: Federal and state accountability policies attempt to improve educational outcomes but have been blamed for a breadth of ills, including minimizing local knowledge and reducing teachers' ability to respond to contextual needs. Teachers in high-needs schools, especially, feel the effects of constrained curricula and increased testing,…

Background/Context: In disability critical race theory (DisCrit) Classroom Ecology, Annamma and Morrison (2018a) offered invaluable direction for teachers by proposing constructs that address racism and ableism within the foundational components of the classroom--curriculum, pedagogy, resistance, and solidarity. These liberatory lenses offered a…

Background: Despite increasing popularity and mounting evidence for teacher collaboration as a lever for school improvement, reported changes in teaching associated with collaboration are often subtle and incremental, rarely involving substantial shifts in instructional practice called for by advocates of deeper learning and next-generation…

Background/Context: School districts are increasingly expected to support students in meeting ambitious mathematical learning goals. Many schools and districts are investing significant resources in the provision of time for teacher collaboration in the hope that this will help teachers improve their instruction in ways that support students in…

Background: Data-based decision making can lead to increased student achievement; however, schools struggle with the implementation of data-based decision making. Professional development in the use of data is therefore urgently needed. However, professional development is often ineffective in terms of improving the knowledge, skills, and attitude…

Background/Context: Schools and districts are increasingly emphasizing evidence-based decision making as a means for improving teaching and learning. In response, professional development efforts have shifted toward situated, sustained activities that involve groups of teachers in reflective inquiry about student learning data, instructional…

Uses the authors' experiences with a professional development project to propose a model of teacher community, describing the challenge of negotiating the essential tension of teacher community and the challenge of maintaining diverse perspectives within a social group. A model of the markers of community formation as manifested in participants'…

Draws on three intensive case studies of teacher knowledge, practice, and learning among teachers of mathematics and English in two high schools in order to examine the problem of how classroom teaching practice comes to be known, shared, and developed among teachers through their out-of-classroom interactions. The article also discusses classroom…
