With the aim of strengthening mathematics teaching | learning, classroom video is increasingly used as a tool for teachers to reflect on their practice. In the first phase of a two-phase design-based study, a group of primary teachers selected, viewed and discussed video excerpts from mathematics lessons. Engaging with and working to reconcile…

This study draws upon critical bifocality (Chen & Horn, 2022) and intersectional frameworks (Collins, 2019; Crenshaw, 1989) to detail critical consciousness development over time in justice-oriented elementary mathematics educators. Specifically, a Critical Participatory Inquiry (CPI) approach facilitated collective theorizing amongst myself…

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…

This article reports on a framework for collective professional learning and its influence on the development of four early-career mathematics teacher educators as they work to transform their practice. The Collective Reflection for Change (CRC) framework centers on a shared referent to orient collaborative noticing and wondering. Findings from an…

Leading mathematics teaching and learning in schools is a complex job that requires the development of specialised knowledge and skills. Opportunities to learn in professional workshops can help to build leadership knowledge and skills. The results presented here describe 262 leaders' prompted reflections at the end of a professional development…

This study examined the practices of a mathematics coach by analyzing coaching moves over multiple coaching cycles with two teachers. The coach, guided initially by a content-focused model of coaching (West & Staub, 2013), engaged teachers in cycles that consisted of co-planning, teaching, and debriefing conversations to help teachers reflect…

Technological tools that provide automated feedback on classroom teaching afford a unique opportunity for educators to engage in self-reflection and work towards improvement goals, in particular to ensure that their instructional environment is equitable and productive for students. More information is needed about how teachers experience…

Video clubs have been used for more than a decade to support teachers' professional noticing. Accordingly, numerous studies have evaluated video use as a tool for professional learning, concentrating on aspects such as video selection, club meetings, and teacher interviews. Yet, few researchers have considered noticing as a result of repeated…

Adaptive learning support is a key element of high quality preschool education and includes the planning of learning situations and teacher-child interactions. The provision of effective adaptive learning support in kindergarten is challenging. This longitudinal experimental study examined the impact of two professional development programs on 132…

We report on the results of a professional development programme involving four Hungarian teachers of mathematics. The programme aims to support teachers in integrating problem solving into their classes. The basic principle of the programme, as well as its novelty (at least compared to Hungarian practice), is that the development takes place in…

Lesson study is a Japanese concept to improve teaching and learning mathematics through a particular form of activity in which a group of teachers works collaboratively to plan, implement, observe, and reflect on the proposed research lessons. Although lesson study is internationally acknowledged as providing key learning opportunities for…

Purpose: This study aimed to explore how an adapted theoretical framework by networking two theories could help document teachers' collective learning through lesson study. Design/methodology/approach: Interconnected Model of Teacher Professional Growth (IMPG) and Documentational Approach to Didactics (DAD) has been used individually to document…

An important step to achieving a sustainable department culture that encourages innovation in teaching is the alleviation of the isolation that teaching faculty experience. Decreasing this isolation should be accomplished in a manner that respects all instructors' classroom practices while simultaneously exposing faculty to new ideas. In this…

We examine aspects of professional collaboration in a lesson study conducted with mathematics teachers from the final years of basic education belonging to public schools in the State of Rio Grande do Sul, Brazil. The lesson study, conceived as a professional development approach focused on collaboration and reflection, took place in the 2nd…

Teachers' decision-making and pedagogical reasoning often become visible in their lesson planning sessions. This study explores how the professional learning opportunities presented by teacher-facilitator interactions in planning sessions.
