A key commitment of the Adult Literacy for Life Strategy (2021) is to reduce the number of adults in Ireland with unmet numeracy needs from 25% to 12%. One of the main challenges in achieving this is the varied provision of adult numeracy education. Many numeracy practitioners are either employed parttime or are volunteers with few opportunities…

Since policy changes in 2014 about who studies mathematics post-16 in England, the mathematics teaching workforce in further education (FE) colleges has grown and diversified. The question of how best to develop the professional practice of this changing workforce is, however, unresolved. Teachers in a recent national study report the benefits of…

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…

The problem addressed in this qualitative single case study is low mathematical achievement levels among students in grades K-4 in rural Vermont schools, based on district-wide and school-based progress monitoring assessments and Vermont's Smarter Balanced Assessment scores. The purpose of this qualitative single case study was to explore the…

Problem-solving is of importance in the teaching and learning of mathematics. Nevertheless, a baseline investigation conducted in 2016 revealed that mathematical problem-solving is virtually missing in South African classrooms. In this regard, a two-cycle design-based research project was conducted to develop a professional development (PD)…

The issue of "social justice" has been regularly addressed in many published papers in mathematics education research, particularly after 2000, when the discipline took a more explicit socio-political turn. However, there does not appear to be a consensus as to what the term designates and includes. This paper is a systematic review of…

Traditional teacher andragogy models oversimplify teaching multilingual students, overlooking both the complexity of identity and the contexts in which this work occurs. In this paper, we describe our intersectional approach to research, highlighting its affordances for research on teachers' learning to support multilingual students. This…

Elementary teachers' mathematical self-efficacy is abundantly important in the mathematical growth in students. Research suggests early career elementary teachers have a low level of self-efficacy in teaching mathematics. The purpose of this study was to examine perceived changes in teacher self-efficacy in teaching math after participating in a…

Teachers are experiencing a change in practice, from teacher-centered to student-centered, which affects their work with English learners (ELs) in third through fifth grade mathematics classrooms. The implementation of student-centered discourse practices is essential to orchestrating productive mathematical discussions. However, the common…

Mathematics teacher continuing professional development (CPD) is widely recognised to encompass more than attending courses and engaging in formal activities with colleagues in school. Teachers' professional reading is an under-researched aspect of CPD, which takes place out of view, but which has the potential to shape teachers' beliefs and…

In 2014 the National Adult Literacy Agency (NALA) published a research report titled "What Really Counts Next: Action Learning Project with Numeracy Tutors" (Sellers and Byrne, 2014). The report provided an in-depth insight into the way tutors made changes to their practice, and offered practical tips on how to teach numeracy to adult…

In this project, a university team of teacher education and mathematics professors conducted eight professional development sessions for General Educational Development (GED) teachers in the area of mathematics teaching. Topics included concretely modeling mathematics concepts in algebra, number sense, geometry, and differentiating instruction in…

Diagnosing student achievement in a formative way is a crucial skill for planning and carrying out effective mathematics lessons. This study takes a subject-specific view and aims at investigating diagnostic competence in the field of mathematical functions at secondary level and how to improve it. Following three evidence-based design principles,…

Much research has been conducted on exploring teacher learning and constituting Continuous Professional Development (CPD) designs for teachers. Yet, little is known about appropriate design principles of CPD for teacher trainers/multipliers who in turn are supposed to provide CPD for teachers. The German Center for Mathematics Teacher Education…

In this paper, we will describe the challenges and insights gained from conducting professional development workshops aimed at helping faculty prepare materials to support the development of students' quantitative skills in different disciplinary contexts. We will examine some of the mistakes we made, and misconceptions we had, in conducting the…
