In poor-performing, resource-constrained education systems, such as South Africa, solutions to improve academic achievement have tended to focus on resources and cognitive factors. An area that requires more attention is the importance of non-cognitive, psychosocial factors and their relationship with academic performance. These factors are…

Globally girls' performance in mathematics has improved over the years as measured by TIMSS results. Inconsistency in mathematics performance of boys and girls is still an area of great concern. This study examines the relationship between mathematics achievement and gender of South African Grade 9 learners from TIMSS 2015 data. The data were…

There is growing global concern concerning South African learners' mathematics achievement, with research identifying many factors contributing to poor mathematics achievement, with class size being one of them. When classrooms are overcrowded, this may lead to a stressful environment which can negatively impact the quality of teaching and…

Much of the focus of international comparative studies of students' achievement has been on New Zealand students' falling standards. Using the most recent findings from the Trends in International Mathematics and Science Study (TIMSS), and, in particular, Year 9 New Zealand students' performance in specific items, this article suggests that there…

Due to the fixed school start in Norway in August of the calendar year of students' sixth birthday, the age span in one class is up to twelve months. This can impact academic performance both in the early years and later. In this paper, we investigate the relationship between birth month and mathematics performance by paying attention to the…

In this study reciprocal peer tutoring was implemented in middle school mathematics classes for a six-month period. The effects of this methodology on students' mathematics achievements, mathematics anxiety levels, attitudes towards mathematics, and mathematics self-concepts were examined. Study participants included 768 students in grades 7-9…

Extant literature has demonstrated the importance of individual and school-related factors in improving mathematics achievement. Despite this, there is still a gap in research to understand the mediating role of educational aspiration in mathematics achievement. The aim of the present study is to test the relationship between self-efficacy, school…

It is widely acknowledged that understanding of science is key to becoming global citizens and to embrace technological advancements. Although research suggests that girl's performance in science has improved over the years, there are still concerns about the under-representation of women in science, technology, engineering and mathematics (STEM)…

Inquiry-Based Teaching Practice (IBTP) is an essential component of science education, and promoting its implementation is at the heart of various reform efforts. Even though science teachers regard IBTP as an essential pedagogical method, they rarely use it for various reasons. This study utilizes Bronfenbrenner's ecological framework to examine…

Teachers use a variety of instructional strategies when they teach various mathematical topics and concepts. Some of these strategies have been found to positively affect the performance of learners while others do not. This study analysed the teacher questionnaire data from the Trends in International Mathematics and Science Studies (TIMSS) 2015…

In the study reported on here I evaluated the alignment between the Annual National Assessment (ANA) and Trends in International Mathematics and Science Study (TIMSS). Theoretical perspectives were drawn from the Survey Enacted Curriculum (SEC), while quantitative correlational methods were used to determine the alignment between ANA and TIMSS…

This study investigated the reading demands of restricted-use items administered to South African grade 9 learners as part of the Trends in International Mathematics and Science Study (TIMSS) 2015. The method proposed by Mullis, Martin and Foy (2013) was used to categorise items into low, medium and high readability groups. The 'knowing' domain…

Teacher well-being is an important issue that needs to be considered within a teaching environment. However, little research exists about the relationship between teacher well-being and learner performance. In this study we used data from the 2015 Trends in International Mathematics and Science Study (TIMSS) to look at the interplay between…

International large-scale assessments (ILSAs) have become an important part of the Swedish evaluation system. It is therefore of crucial importance to validate national measures of Swedish students' achievement with their ILSA test scores. Here, we offer results from such a validation study based on Swedish students' test scores in IEA's Trends in…

This study investigates consistent and inconsistent respondents to mixed-worded questionnaire scales in large-scale assessments. Mixed-worded scales contain both positively and negatively worded items and are universally applied in different survey and content areas. Due to the changing wording, these scales require a more careful reading and…
