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…

Since CLIL (Content and Language Integrated Learning) implementation is context-dependent, this cross-sectional quantitative study aims at assessing the impact of parental educational background on CLIL learners' content subject learning. Statistically significant differences in Science knowledge emerged in favour of bilingually educated learners…

Following a theoretical framework that recognizes the potential of promotive and inhibitive effects on children's development, this study explored child-, family-, classroom-, and school-level factors as predictors of Latinx (N = 4,590) students' early elementary science achievement. Research Findings: Employing a path modeling approach with…

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…

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…

The innovative-based economies such as Finland and other developed countries, offer a viable cohesive, and sustainable curriculum centralized around Project-Based Learning (PBL) and built on the Rigorous Curriculum Design (RCD). Such curriculum is developed by schools and warrants examination in developing countries such as the United Arab…

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…

Sub-Saharan Africa secondary school science curricula recognise language as the most important communication tool for learners' biology learning outcomes. Despite this prominent goal, learners' scientific literacy at secondary school appears to be insufficient to cope with classroom teaching and learning of biology. This paper presents a review of…

English Language Learner (EL) students in the district's two main bilingual programs (Transitional and Dual Language) are instructed in both English and Spanish. The relative amount of instruction in each language depends on both program and grade level. In the Transitional bilingual program, students receive primary language instruction for…

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 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 Houston Independent School District offers two primary bilingual programs (transitional and dual language) for Spanish-speaking English learners (ELs). The relative amount of instruction in each language depends on both program and grade level. Students in the transitional bilingual program have the option of entering a "pre-exit…

The present study examined the roles that language of assessment, language dominance, and teacher language use during instruction play in Dual Language Learner (DLL) science scores. A total of 255 Head Start DLL children were assessed on equated science assessments in English and Spanish. First overall differences between the two languages were…

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…
