Ebo Amuah; Ernest Kofi Davis – African Journal of Research in Mathematics, Science and Technology Education, 2023
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…

Albin, Simon; Brown, Bruce – African Journal of Research in Mathematics, Science and Technology Education, 2019
Learning rational number concepts is acknowledged as an important task but many learners find it difficult to make sense of them. This paper reports on a case study of the learning in a short (nine-lesson) learning programme for Grade 8 learners in a Namibian school, which sought to use visual models (circle area, bar area and number line) to…

Potgieter, Pieter; Blignaut, Pieter – African Journal of Research in Mathematics, Science and Technology Education, 2018
The Department of Basic Education in South Africa has identified factorisation as a problem area in Mathematics teaching. Learners in earlier grades are exposed to mathematical tasks, involving concepts, such as factors of integers, fractions, equivalent fractions and prime numbers, that are easier to solve when the divisibility rules are applied.…

Jagals, Divan; van der Walt, Marthie – African Journal of Research in Mathematics, Science and Technology Education, 2016
Metacognition encompasses knowledge and regulation that, through reflection, sustain problem solving behaviour. How metacognitive awareness is constructed from reflection on metacognitive knowledge and regulation and how these reflections enable metacognitive skills for Mathematics problem solving remain unclear. Three secondary schools…
