In recent years, the number of studies examining resilience in relation to mathematics teaching/learning (or mathematical resilience, according to some), increased significantly. This paper is a systematic review of 78 studies published between 2010 and 2021, and investigates (a) conceptualisations of mathematical resilience, (b) demographic characteristics of participants in the papers identified, and (c) factors that influence the development of mathematical resilience. Our analysis indicates that mathematical resilience is conceptualised in two ways: as the coexistence of disadvantage and high mathematical performance; and, as part of one’s mathematical identity. Participants in related studies belong to one of the following categories: disadvantaged pupils; “typical” pupils; disadvantaged university STEM students; “typical” university students; prospective teachers; in-service teachers. Mathematical resilience is found to be influenced by both psychological and social/environmental factors. Finally, we discuss implications and how the field can move forward.

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 the empirical studies published from 2000 until the middle of 2019 that explicitly address social justice from the perspective of practising mathematics teachers and/or teaching. More specifically, we examine (a) how social justice is conceptualised in the identified studies, (b) what specific issues are investigated and methodological approaches employed to do so, and (c) the main key points that arise from their empirical findings. Implications and suggestions of how the field can move forward are discussed at the end.

In this paper, we examine the national curricula for primary mathematics for each of the four constituent nations of the United Kingdom (England, Northern Ireland, Scotland and Wales) for the estimation-related opportunities they offer children. Framed against four conceptually and procedurally different forms of estimation (computational, measurement, quantity and number line), the analyses indicate that computational estimation and measurement estimation were addressed in all four curricula, albeit from a skills-acquisition perspective, with only the Scottish offering any meaningful justification for their inclusion. The process of rounding, absent in the Northern Ireland curriculum, was presented as an explicit learning objective in the English, Scottish and Welsh curricula, although it was only the Scottish that made explicit the connections between rounding and computational estimation. In all curricula, both quantity estimation and number line estimation were effectively absent, as was any explicit acknowledgement that learning to estimate, irrespective of its form, has a developmental role in the learning of other mathematical topics.

Research around mathematics teachers’ professional noticing has been largely contextualised by the formal setting of the classroom. In addressing the lack of relevant studies in non-formal learning environments, this paper draws on student teachers’ observations within a Mathematics Fair, which was part of a mathematics methods module of a primary education undergraduate programme. Working in pairs, 64 student teachers designed interactive mathematical games which upper primary school pupils had the opportunity to play in an event having taken place at our university. In this study, we analyse student teachers’ individual reflective essays written after the Fair, where they discussed important, in their view, incidents and observations. Employing a thematic analysis approach, we identified four themes discussed by students: the task; learning; teaching; non-formal environment. We conclude with the implications for teacher education and suggestions for future research.

Norwegian classrooms have become more culturally diverse due to immigration. School mathematics is frequently misperceived as the subject least impacted by demographic changes. In this paper, we draw on two important concepts – identity and culture – to explore how children of immigrant background construct their identities as mathematics learners. Data collection include classroom observations, focus groups, and individual interviews with three 12-year-old children in Oslo: Amar, Laila, and Maya. Thematic analyses yielded four themes around which pupils construct their identities. The first two regard positioning of the self in the mathematics classroom, and future-oriented self. The latter are concerned with family-related issues: parents’ role in identity construction, and mathematical methods used at home. Finally, we discuss how our work opens avenues for further investigations.
