Background: South African township learners are known to perform poorly in international tests, including reading and science. Language is a complicating variable as English, the learners' second language (L2), is generally the language of learning and teaching, including for reading science texts. Aim: The study's objectives were to determine the…

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…

Science performance is highly affected by students' reading comprehension. Recently, there has been a growing attention to the role of linguistic features for science performance, but findings are ambivalent, especially when looking into item word count. The aim of this study was to investigate the interaction of students' reading comprehension…

The language used as a medium of instruction (MOI) has implications for learning outcomes. In most African classrooms, an international language is solely or dominantly used as an MOI. There is a debate about how this practice is associated with students' learning outcomes. This study uses Zambian PISA for Development 2018 data and school fixed…

We explore the impact of the language of instruction on academic performance of Arabic-speaking students who are expected to learn mathematics and science in and through a second language (L2). Using as a theoretical background Cummins's (1984) framework relating language proficiency to academic achievement, we provide some insights into the…

A general validity and survey quality concern with student questionnaires under low-stakes assessment conditions is that some responders will not genuinely engage with the questionnaire, often with more random response patterns as a result. Using a mixture IRT approach and a meta-analytic lens across 22 educational systems participating in TIMSS…

This article claims to provide evidence on whether content-subject and cognitive achievement vary in CLIL (Content and Language Integrated Learning) and non-CLIL classrooms in the framework of a newly introduced CLIL programme in Italy. A standardized and validated science test (TIMSS) was administered to a sample 988 fourth-grade students. The…

Understanding the long-standing educational inequities associated with socioeconomic status remains significant for transforming educational policies and practices. To better understand entanglements among socioeconomic status and students' performance in mathematics, we examined different home factors (including language of the test) that…

Purpose of the study: The purpose of the study is to investigate Mathematics and Science elementary school teachers' perceptions of using English as a medium of instruction in the United Arab Emirates (UAE) primary schools. Methodology: This research utilized an explanatory sequential mixed-methods design. The first phase of the research featured…

This cluster randomized control trial examines the effects of the Science Notebook in a Universal Design for Learning Environment (SNUDLE) on elementary school student science academic achievement and motivation outcomes. Multilevel analyses examined the impact of SNUDLE for all students and important student subgroups. Overall, students who…

Volume 1 of the "TIMSS 2023 National Report for England" analysed the TIMSS 2023 performance of a sample of year 5 and year 9 pupils in mathematics and science in England. This second volume of the "TIMSS 2023 National Report for England" focuses on performance in England analysed by pupil characteristics and participating…

Using Malaysia TIMSS 2015 data, this study examined the association between eighth grade students' science achievement and mathematics score and the determining factors of science achievement. A total of 9,726 students participated in TIMSS 2015 with an average score of 508.60 with standard deviation of 89.86 for science and 501.57 with standard…

The Language and Culture Division (LCD) provides accountability with support to districts that serve students participating in Bilingual Multicultural Education Programs (BMEPs) so that all participating students achieve the program goals as outlined by New Mexico statute and administrative code, which are: (1) students become bilingual and…

Choice of instructional language is influenced by both previous and current perceptions of the value of a given language. For many South African learners, this has contributed to their education being presented either partially or entirely in a second or third language. This effectively limits their cultural capital and educational opportunities.…

As the content knowledge of English language learners and immigrant students is assessed in their less proficient language, the validity and fairness of assessments related to those students have been widely discussed. However, such assessment issues have not received much attention in rapidly expanding bilingual education programmes, where…
