The present study explores the validity of inferences that may be drawn from the Trends in International Mathematics and Science Study (TIMSS) learner achievement data by measuring the South African curriculum-TIMSS alignment for the Grade 8 science assessments from 2007 to 2019. The Singapore curriculum--TIMSS alignment indices are a fair…

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…

Learning mathematics is as much about developing relationships with mathematics as the development of mathematics concepts and skills. Mathematics clubs usually support learners to develop relationships with mathematics through engaging with challenging mathematics problems, exploring mathematical ideas, and communicating and sharing their ideas.…

The use of guided inquiry-based learning (GIBL) in a manner designed to challenge individual students' unscientific conceptions of science, has been researched widely. However, few (if any) studies have investigated the implementation of GIBL in a manner designed to challenge the fundamental patterns of students' context-dependent unscientific…

Mathematics is a gateway to science-related careers and all stakeholders want to improve the achievement levels in mathematics. In this study we use data from the Trends in International Mathematics and Science Study 2015 to investigate the association between the learner situational factors of gender, grade level age appropriateness, school…

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…

Research findings show that inquiry-based science education has positive effects in improving learning of both science content knowledge and scientific inquiry (SI) skills. As a result, various science curricula, including that of Namibia, recommend the use of an inquiry-based approach in science teaching. However, the implementation of an…

Mathematics is frequently considered as value-free, centering entirely on abstract reasoning. However, more often than not, the teaching of values in mathematics classrooms takes place implicitly through the actions of the teacher. The role values play in mathematics learning is also a growing area of interest and is now viewed by many as a…

Physical sciences teachers in low-quintile South African schools avoid the use of inquiry on the grounds of inefficiency and ineffectiveness for test preparation. This avoidance is consistent with the view that the high cognitive load inquiry offers to extreme novices such as these learners may be prohibitive. Given the purported benefits of…

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…

The context of the township school provides several hurdles for learners engaging in school science, including low achievement and self-confidence. The use of multiple representations has been advocated for the development of conceptual understanding in physics. The study reported in this paper explores the relationship between learner academic…

The chain of progression from teacher education to qualification to classroom instruction and student engagement, and then to learning and achievement, is not as straightforward as often presented. Societal, political and economic pressures create either a positive climate or a stressful one for both teachers and students. Nevertheless it is safe…

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.…

South Africa participated in TIMSS from 1995 to 2015. Over these two decades, some positive changes have been reported on the aggregated mathematics performance patterns of South African learners. This paper focuses on the achievement patterns of South Africa's high-performing Grade 9 learners (n = 3378) in comparison with similar subsamples of…

This article reports on a study that investigated the extent to which 57 Grade 6 students at a particular school have misconceptions regarding equality, with the equal sign as focus. It also investigated this school's three Grade 5 and 6 teachers' mathematical knowledge for teaching regarding equality, again focusing on the equal sign. The…
