Background or Context: Amid a backdrop of increasing deprofessionalization of teaching and teacher education, education researchers and reformers continue to highlight the complexity and expertise of these professions. Expertise-as-process (Bereiter & Scardamalia, 1993) is a conception of expertise that eschews the traditional focus on…

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: Today's teachers are turning to online educational marketplaces, such as TeachersPayTeachers.com (TpT), where they purchase teacher-created classroom materials for a small fee. Meanwhile, teachers who sell resources in these spaces, online teacherpreneurs, stand to benefit financially and may experience other affordances as well as…

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: 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: This article introduces the special issue on reimagining research and practice at the crossroads of philosophy, teaching, and teacher education. The authors provide an overview of previous research at this "crossroads" and describe how the special issue collaborators have sought to chart fresh ground in light of…

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/Context: Teacher collaboration, instructional practices, and efficacy are linked in various ways in the literature. For example, in schools where teachers reported greater use of differentiated instruction, team collaboration and culture were reportedly higher (Smit & Humpert, 2012). Further, teachers' instructional mastery…

Background: Data-driven decision making continues to be a common feature of educational reform agendas across the globe. In many U.S. schools, the teacher team meeting is a key setting in which data use is intended to take place, with the aim of planning instruction to address students' needs. However, most prior research has not examined how the…
