Background: Numerous studies show that active and engaging classrooms help students learn and persist in college, but adoption of new teaching practices has been slow. Professional development programs encourage instructors to implement new teaching methods and change the status quo in STEM undergraduate teaching, and structured observations of…

Our aim is to contribute to the body of research on learning trajectories (LTs) in mathematics by making visible a process for articulating a hypothetical learning trajectory implicit in a widely adopted, reform-based, middle-grades mathematics curriculum. In doing so, we highlight considerations, decisions, and challenges we faced as part of this…

Textbooks play a vital role in the Nepali education system since they are one of the main resources for teaching and learning mathematics. Because of poor physical infrastructure and inadequate educational resources, both teachers and students heavily rely on textbooks. In this regard, this study investigated the mathematics textbook authors'…

The need to improve math instruction in the United States has led to a variety of reactionary reform efforts. Often, these reforms require teachers to step away from deeply embedded instructional practices, which are difficult to change. Professional learning communities (PLC) are a common form of professional development in education that have…

Mathematics education researchers examined teacher practices that support students who have historically been marginalized and have underperformed in school. These efforts have led to much discussion about how to incorporate culturally responsive pedagogy (CRP) theoretically and pragmatically. Many teachers want to develop and implement more…

A three-phase "task-first" lesson structure is frequently suggested when teaching mathematics through inquiry. We investigate how secondary school teachers of mathematics structure their inquiry lessons and examine how and why they deviate from a "task-first" structure. We present detailed lesson observation data from three…

This study concerns a professional development course designed and implemented for prospective teachers, centred on a teaching method regarding problem-solving activity, namely, the Thinking Classroom. The study is framed in the theory of cultural transposition, a perspective about the encounter with teaching practices from different…

Beginning teachers are challenged to make concrete the identities they envision for themselves in their practice. We examine how a particular context, the noticing interview, supported a novice teacher's identity work through disciplined awareness to cultivate the inner witness. In a noticing interview, teachers view and discuss video segments…

The article focuses on rehearsals as part of a practice-based approach to professional development. Fourteen Norwegian elementary in-service teachers (ISTs) collaborate in learning cycles of enactment and investigation, where the overarching aim is to learn to enact the practices that constitute ambitious mathematics teaching. Rehearsals are an…

This brief research report examines the discursive shifts of a secondary mathematics teacher participating in a collaborative learning community centered on culturally responsive mathematics teaching. We draw on two frameworks to analyze the teacher's discursive moves. The first framework comes from Lefstein et al. (2020) on generative discourse…

This discussion explored the integration of creative thinking pedagogy and the anthropological theory of didactics in university-level algebra education, emphasizing the importance of understanding the perspectives of both learners and teachers. The work began by highlighting the necessity of considering these viewpoints to create effective and…

This report is about how a group of U.S. teachers (N = 98) and researchers used a boundary object in a collective study of grades 6-8 mathematics instruction. The focus is the teachers' engagement with a framework for effective instructional practices. Using qualitative content analysis of teachers' responses to use of the framework, we assessed…

Purpose: The purpose of this study is to examine what teachers notice in their own enactment of eight high leverage practices as well as the patterns of interactions between the teachers and their peers when participating in video-based lesson study. Design/methodology/approach: Each teacher taught and uploaded video from one lesson to a platform,…

Many studies have documented a large decline in students' mathematics achievement during and after the coronavirus disease 2019 (COVID-19) pandemic. The question facing school districts now is how to help students recover. Since fall 2020, RAND researchers have repeatedly surveyed and interviewed district leaders who are members of the American…

Group discussions during mathematics lessons provide important opportunities for students to deeply engage with mathematics content and to develop communication skills and strong understanding aligned with college and career readiness objectives (Walshaw & Anthony, 2008). However, such student-centered discussions are less common than…
