This study investigated children's knowledge of the addition of fractions with unlike denominators. It focussed on the strategies used by children to add fractions with unlike denominators. A cross-sectional survey of Grade 8 children in schools in two districts in Ghana was used. A test on the addition of fractions with unlike denominators was…

Research on mathematical equivalence, and to some extent, on number structure in early grade mathematics, has shown that most students at primary and secondary levels understand these concepts instrumentally rather than relationally. The study reported in this paper uses a design research approach to explore both mathematical equivalence and…

In this article we share the findings emanating from a 20 year (2003-2022) review of South African Early Grade Mathematics (EGM) research articles published in key international and local/regional journals. The review shows a substantial increase in the volume of published EGM articles in the second decade (2013-2022), nationally and…

The development of statistical literacy has become a key outcome of mathematics curricula in various countries. The purpose of the study was to explore primary pre-service teachers' (PSTs') knowledge of aspects of measures of central tendency, which is a central concept in statistical literacy. The 183 PSTs' written responses to four tasks were…

The aim of this paper is to analyse the reasoning and symbolisations used by sixth grade Moroccan students in solving a task based on figurative patterns. Our analysis aims at identifying the systems of actions elaborated by the students to give the general expression of the sequence, according to their perceptions of the sequence of its patterns.…

This study investigated the extent to which the proposed Factory of Ideas (FOI) teaching approach impacted on students' understanding of energy based on their prior knowledge. The FOI is a didactic approach that, unlike the classic cognitive conflict approach, employs a variety of activities to offer students a scientific conception for comparison…

In this paper, illustrative excerpts from mathematics lessons are analysed to examine mathematical and multilingual moves between representations within Sepedi and English medium classrooms. Duval's theory of representational registers and the literature on multilingual practices help foreground similarities within and differences between the…

One of the biggest challenges for primary school children is moving beyond the use of counting in calculation. The purpose of this study was to investigate how Zambian Grade 1 to Grade 4 children at primary school see a group of 10 as an effective pattern and structure with the given concrete material. The study consisted of three phases…

This study examines the relationship between teacher quality and student achievement in Mathematics among Grade 4 pupils located in 91 urban primary schools and 181 rural primary schools in Kenya. We hypothesise that teacher quality indicators including teacher characteristics, teacher qualification comprising initial teacher education and teacher…

While a consensus within the field exists that pre-service teachers need adequate knowledge and skills to become effective teachers in mathematics, less is known about how they understand the mathematical knowledge needed for teaching in elementary education. This paper explores how Malawian pre-service teachers understand the mathematical…

The purpose of this study was to provide a systematic review of research that has been carried out between 2006 and 2016 on the role of language in early grade (Grades 1-4) mathematics teaching and learning in three countries--Kenya, Malawi and South Africa. These countries were selected because they have similar characteristics: teaching and…

This paper reports on the professional development of four mathematics teachers in South Africa. The four teachers all participated in a Mathematical Thinking course before taking an Advanced Certificate in Education in mathematics. The research, which aimed to understand these teachers' ongoing professional development, took place two years after…

This article looks at the development of mathematisation in a primary school mathematics teacher's classroom. The teacher was a volunteer in a professional development programme that promoted didactisation principles for mathematics teacher development. At the heart of didactisation lies the principle of mathematisation. Mathematisation as a…

Drama is used to build knowledge and understanding in science as part of a socio-linguistic, constructivist approach. Role-plays, where learners act as analogues for components and processes, help access abstract ideas. However, a problem restricting many science teachers using these approaches has been that they lack sufficient pedagogical…

This paper reports on the findings from individual interviews and focus group discussions involving six teachers implementing the Singapore Mathematics Curriculum (SMC) in the Foundation Phase (Grade R to Grade 3) in a school in South Africa. The interviews presented an opportunity to explore teachers' experiences with their attempts to use the…
