The Parts and Parcel: A Collegiality Model for Teacher Disciplinary Professional Learning Communities

While teachers’ professional learning communities (PLCs) have been extensively studied, discipline-specific PLCs (DPLCs) have received less attention, particularly regarding the subject matter’s role and its connection to other community dimensions. To explore this, we conducted two independent studies on DPLCs. Study 1 examined physics teacher DPLCs, using participant observations and literature-based analysis. Study 2 investigated science and technology teacher DPLCs through interviews and passive observation, which was analyzed through content analysis. Both studies yielded remarkably similar findings, leading to a synthesized model encompassing five dimensions: the structural dimension, reflecting the community’s tangible and logical organization; the content dimension, emphasizing the discipline-specific focus of the DPLC; the common production dimension, showcasing joint enterprise activities and products of the DPLC; the social-affective dimension, addressing social, emotional, and value-based aspects that establish a sense of community; and the meta-community dimension, exploring the DPLC’s relationships with its broader environment. These dimensions operate bidirectionally: inward—the effect of the community on the individual, and outward—the effect of the individual teacher on the community. We discuss how interactions between these dimensions shape DPLCs and influence teacher development. Additionally, we highlight the significance of this unified model for DPLC leaders, researchers, and policymakers in teacher development.
