This design research study describes how one mentor teacher-teacher candidate dyad co-learned to promote student engagement and participation through using a "Collaborative Learning Structure" (CLS) tool that we are developing. We share how the dyad used the CLS, with support from a professional development facilitator and fellow…

Reports on a research project designed to implement an adapted Lesson Study cycle whereby pre-service mathematics teachers co-create a lesson with an experienced expert instructor and observe the instructor teach the lesson. Results show development in the pre-service teachers' attention to elements of planning such as anticipation and pedagogical…

Drawing on data collected from one coaching cycle during mathematics instruction for one coach-teacher dyad, this study explores one instructional coach's discursive enactment of their coaching stance. Qualitative analyses indicate that there was dissonance between the coach's stance for coaching and their discursive enactment of coaching, and…

Drawing on a concept-map methodology, we investigated how 18 prospective elementary teachers (PSTs) conceptualize STEM thinking as habits of mind shared across STEM domains in the context of problem-solving prior to explicit classroom discussions about STEM thinking. A 28-question, 5-point Likert-scale survey was used to explore PSTs' orientations…

This study explores how five beginning elementary teachers used their mathematics curriculum materials in their first three years of teaching. Prior research suggests that teachers' curriculum material use in their earlier careers may not change significantly from year to year (e.g., Valencia, Place, Martin, & Grossman, 2006). Our…

Noticing children's mathematical thinking is foundational to teaching that is responsive to children's thinking. To better understand the range of noticing expertise for teachers engaged in multiyear professional development, we assessed the noticing of 72 upper elementary school teachers using three instructional scenarios involving fraction…

To base teaching on student thinking requires analyzing and interpreting students' thinking, key components of the construct of professional noticing (e.g., Jacobs et al., 2010). Although substantial research has been conducted using this construct, less attention has been paid to teachers' evaluations of student work based on these analyses and…

Research on pre-service teachers' discussion practices has focused on decompositions of practice into subskills, while acknowledging the importance of the role of context, identity, and relationships between interactive moves. We focused on 66 elementary preservice teachers' (PSTs') framing-launching moves in discussions after problem-solving in a…

In a research study designed to investigate the emergence of collective creativity in elementary classroom settings, and in which teachers' decision-making practices were analyzed alongside both the teachers' observed teaching practices in their classrooms and their students' problem solving actions, the first author developed four metaphors for…

We investigated how 53 elementary teachers interpreted the impact of the contexts in which they work on their mathematics instruction, and what those interpretations reveal about the agency individual teachers were able to achieve. Latent class analysis revealed two distinct classes, with teachers in one class perceiving that their contexts had a…

How teachers can experience adaptive professional development (PD) experiences is still understudied in the literature on teacher learning, which for the most part reflects an emphasis on learning outcomes rather than the process of learning. In this study, we use a situated perspective on teacher learning to investigate the coevolution of a…

Positioning theory has been used in research to understand how elementary student teachers are positioned while working with their mentor teacher. While this research has identified four general positions, there remains a lack of clarity about these positions, particularly in how they differ. This study explores three contrasting student…

Number talks, a popular mathematics teaching routine in the United States, may offer supports for beginning teachers (BTs) to engage in ambitious instruction. BTs' enactments of number talks, however, are varied, and there are few empirical studies that explore how BTs' enactment of number talks could be more (or less) ambitious. This paper draws…

In this paper we examine how teachers who are pursuing their Elementary Mathematics Specialist certification--Elementary Mathematics Specialists in Training (EMSTs)--are positioned in their advice and information networks for mathematics. We analyzed the instructional networks of six elementary schools in one Midwestern school district. Our…

The purpose of this project was to understand how implicit views of authority support or limit prospective elementary teachers' (PTs) mathematical activity of justifying and to understand how the experience of justifying might support a development of an internal source of authority. In this case study of 18 PTs, we coordinate an analysis of (1)…
