The COVID-19 pandemic caused widespread disruptions to education, with school closures affecting over one billion children. These closures, aimed at reducing virus transmission, resulted in significant learning losses, particularly in mathematics and science. Using data from TIMSS 2023, which assesses fourth and eighth-grade achievements across 71…

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…

The aim of this study is to examine whether or not the positive and negative items in the Mathematical Self-Confidence Scale employed in TIMSS 2015 lead to wording effect. While examining whether the expression effect is present or not, analyzes were conducted both on the general sample and on a separate sample for female and male students. To…

In Lebanon, science is taught in an international language (French or English) based on a language-in-education policy rooted in Lebanon's colonial history. Given the intersection among social/socioeconomic class, educational equity, and science performance, learning science in a language other than one's own raises concerns around…

The quality of education is a predictor of a country's economic performance -- which is why comparative international education surveys are important. South Africa performed poorly in the Trends in International Mathematics and Science Study (TIMSS) in 2019. The score of 374 for mathematics and 324 for science is poor compared to the mid-point of…

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…

The article discusses the diversity and equity issues behind the learning outcomes of mathematics in the pre-COVID context in Nepal. The article intends to give a baseline for the further studies on the effect of COVID-19 pandemic in the educational realm. Datasets from the national assessment of student achievement in Nepal at grades 3 and 5 and…

Bullying victimisation is a reality in most schools around the world, with thousands of students being victimised on a daily basis. Given the prevalence of bullying victimisation at school, examination of what might prompt or prevent such behaviours is required. Therefore, this study examined the relationship of a number of individual and…

Determinants of educational achievement extend beyond the school environment to include the home environment. Both environments provide tangible and intangible resources to students that can influence science achievement. South Africa provides a context where inequalities in socio-economic status are vast, thus the environments from whence…

It is well documented that academic achievement of students from families of low socioeconomic status (SES) tends to be below their more socially advantaged peers. Several studies have identified factors and conditions that facilitate academic success for disadvantaged students (i.e., promote academic resilience). However, one of the main…

STEM education is a current focus of many educators and policymakers and the Next Generation Science Standards (NGSS) with the Common Core State Standards in Mathematics (CCSSM) are foundational documents driving curricular and instructional decision making for teachers and students in K-8 classrooms across the United States. Thus, practitioners…

Across Europe we can observe the reinforcement of monolingual education policies, despite increasing multilingualism. Recent research has shown that the emphasis is on language proficiency in the socially dominant language. This is viewed as the key to educational success. The use of other languages or linguistic repertoires is not valued in…
