This qualitative exploratory case study focused on a Professional Development (PD) program for mathematics teachers in the public system, which is an underserved community of teachers in Chile. The study aimed to understand how the program addressed the challenges brought by the pandemic. Using semi-structured interviews and drawing from a…

For educators, identifying and characterising problems in their teaching practice is essential for triggering inquiries into their practice. Knowing what educators consider problematic is essential for generating strategies for situated approaches to help teacher educators manage their problems and promote professional learning. In this study, we…

Central to criticisms of teacher professional development is an insufficient focus on its impact including minimal evidence of changes to practice coupled with inadequate emphasis on student outcomes. This year-long study of one case study school investigates the impact of a seven-month professional development initiative designed to support…

While coaching is a well-documented form of professional development to support teachers' instructional practices in mathematics, limited research exists on how coaches can support teachers in differentiating their mathematics instruction. Hence, as part of this retrospective case study, we explored how one instructional coach leveraged a coaching…

Evaluations of professional development programmes often seek to represent definitive outcomes, with phenomena posited as discrete, bounded and independent entities, and researchers positioned as external actors. An alternative is to understand the complexity of these relationships as entanglements by applying Baradian concepts. The value of this…

This study investigates the impact of a professional development programme in formative assessment (FA) for high school mathematics teachers. Through a collaborative approach between researchers and in-service teachers, a 16-week online course was designed focusing on feedback strategies, peer co-assessment, and student engagement. A mirrored…

Learning to teach out-of-field is a challenge that many teachers worldwide face at some time in their career. Whether they are motivated to seek formal professional development as additional qualifications in this area, however, depends on many factors. Alignment between the specific professional development needs of out-of-field teachers and the…

There is a need to strengthen the theory-practice connection, particularly for early-career mathematics teachers, through effective professional development (PD) programs that integrate theory and research with the implementation of classroom practices. The current study investigates the effect of the online coaching component a hybrid…

Lesson Study is a professional development program, which engages teachers in a collaborative and long-term lesson planning process aimed at improving a single or a group of lessons. In the process, teachers may feel that they are offered three different types of support: social, emotional, and instructional. The purpose of this study was to…

Teachers' perceptions of students' capabilities are particularly important in efforts to support ambitious instructional reforms. In this paper, we explore one teacher's efforts to resolve conflicts and tensions as she engages with new practices associated with ambitious mathematics teaching. While many conflicts arose in the first year of the…

This article describes the normative beliefs and the discursive claims related to mathematics and teaching mathematics made by approximately 50 middle-level and secondary mathematics teachers within four high-need local education associations participating in a Mathematics and Science Partnership with a southeastern college's Science and Math for…

Engagement in practitioner inquiry by classroom teachers is a promising mechanism for teacher professional learning. While much has been learned about the positive role inquiry can play in traditional professional development efforts, we know less about the impact of inquiry in a rapidly advancing technological age that includes the proliferation…

This study examined processes at the core of teacher professional development (PD) experiences that might positively impact teacher learning and more specifically teacher change. Four processes were considered in the context of a PD program focused on student mathematical errors: analysis of students' mathematical misconceptions as a lever for…

Let's Count is a mathematics professional learning programme for preschool educators in Australia, managed by a prominent non-government organisation and sponsored by industry. It has been implemented in both face-to-face and online modes over 2013/14. Let's Count is based on the constructs that all young children are powerful mathematicians and…

The main goal of the Learning and Teaching Geometry project is to build professional development materials that provide opportunities for teachers to learn about mathematical similarity through the use of videocases, in which specific and increasingly complex mathematical ideas are presented within the dynamics of classroom practice. The central…
