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/Context: The 1960s open space school removed partitions between classrooms in part to alleviate teacher isolation. The model was long ago deemed a failure. Years later, teachers in surviving open space facilities continue to navigate the reform. Despite wide dismissal of the model, components of teachers' work that open space schools…

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/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 leaders, teachers, and researchers are increasingly involved in collaborative research and development (R&D) projects in schools, which encourage crossing boundaries between the fields of school and research. It is not clear, however, what and how professionals in these projects learn through cross-professional…

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: In light of the growing complexity of schoolwork, it is important that faculty members move away from isolated learning toward a more collective type of thinking regarding teaching and learning issues. Purpose: Whereas collective learning has mostly been approached from a deficit-based orientation (finding/solving problems and…

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…

Background/Context: The collegial analysis of student work artifacts has been effective in advancing the practice of experienced teachers; however, the use of such strategies as a centerpiece for induction has not been explored, nor has the development of tool systems to support such activity with novices. Purpose/Objective: We tested the…

Background/Context: Research shows that teachers' understandings of students, subject, and teaching influence their classroom practice. Additionally, teachers' colleagues have a role in shaping individuals' approaches to teaching and their responses to reform. Focus of Study: To understand how interactions with colleagues support teachers'…
