One of the major challenges in educational reform is supporting teachers and the profession in the continual improvement of instruction. Research-practice partnerships and particularly networked improvement communities are well-suited for such knowledge-building work. This article examines how a networked improvement community with eight school-based professional learning communities—comprised of secondary science teachers, science and emergent bilingual coaches, and researchers—launched into improvement work within schools and across the district. We used data from professional learning communities to analyze pathways into improvement work and reflective data to understand practitioners’ perspectives. We describe three improvement launch patterns: (1) Local Practice Development, (2) Spread and Local Adaptation, and (3) Integrating New Practices. We raise questions about what is lost and gained in the transfer of tools and practices across schools and theorize about how research-practice partnerships find footholds into joint improvement work.

Preservice teacher performance assessments, such as the edTPA, are one of the accountability policies from states and local authorities designed to ensure the quality of beginning teachers and standardize teacher education. We studied experiences of 65 preservice teachers regarding the effect of the edTPA on their learning in field-placement classrooms. These cases revealed that the edTPA created "protected teaching spaces" for participants to experiment with student-centered instructional practices supported in university courses and codified in edTPA rubrics. This was especially impactful for novices who previously had limited opportunities to try out equitable reform-oriented instruction in their placements. In these cases, the edTPA also helped mitigate inequities in learning to teach, an unintended outcome that is important for policymakers to consider when deciding on credentialing requirements.

Teaching to support students' sense-making is challenging. It requires continuous, context-dependent decision-making about which student ideas to pursue, when, how, and why. This paper presents a single case study of an experienced teacher, Nadine, as an illustrative case in order to provide a rich description of this teacher's decisional episodes. Specifically, we characterize Nadine's pedagogical reasoning for decisions to make space for or close down student sense-making while facilitating whole-class discussions. We analyzed video recordings of (1) Nadine's classroom teaching over the course of two instructional units, (2) classroom moments tagged by Nadine or researchers in the midst of her teaching capturing her rationales for instructional decisions, and (3) interviews about those tagged moments. Using constant-comparative analytic methods, we identified three dimensions of criteria that Nadine considered in her decisions about whether to pursue student ideas: (1) disciplinary potential, (2) potential for fostering the classroom community, and (3) curricular considerations. We present four episodes that feature Nadine's reasoning, two in which she intentionally made space for student sense-making and two in which she intentionally closed down lines of student reasoning. Regardless of the decision, the criteria Nadine considered were sometimes aligned, supporting a straightforward decision, and other times created tensions. Across four episodes, we show how Nadine navigated multidimensional criteria; considered students' long-term trajectories; and considered for whom pursuing sense-making would be beneficial. We argue that these navigational considerations might serve as focal points as teachers, researchers, and professional learning facilitators make sense of teachers' instructional decisions as they occur during instruction and that leveraging them to open opportunities for discourse with teachers can support complex teaching practices.

Calls to immerse students in the sensemaking practices of science recommend that students propose ideas and work together to construct explanations as well as drive the evaluation and decision-making around classroom knowledge-building. In other words, they should be participating with epistemic agency. Part of the teaching work of supporting student sensemaking, therefore, is to intentionally open up space for student contributions and negotiations during sensemaking. The type of space that is opened up for students' sensemaking is highly dependent on teachers' choices and interpretations of student contributions. Accordingly, this paper leverages a teacher noticing framework to begin to characterize the teacher noticing and decision-making involved in supporting students' epistemic agency while teaching. Using a novel point-of-view video collection methodology, we asked two teachers to identify moments while teaching in which they were making a decision about how to open up or close down space for students' epistemic agency. We found that both teachers attended similarly to the "disciplinary substance" of students' ideas; the "epistemic nature" of students' ideas; students' "epistemic stance or orientation" during participation; and students' overall "degree of engagement." Teachers' responses to students varied across pedagogical phenomena, and they also varied in their effectiveness. These variations were related to each teacher's conception of epistemic agency. We propose that attention to the "epistemic nature" of students' responses and to students' "epistemic stance or orientation" may be especially important foci of teacher attention for supporting students' epistemic agency.
