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…

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…

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…

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…

According to the internal/external frame of reference model, academic achievement has a strong impact on people's self-concept, both within and between subjects. We conducted a series of meta-analyses of k = 505 data sets containing the six bivariate correlations between achievement and self-concept in two subjects. Negative paths from achievement…

Programme for International Student Assessment data from 29 countries was used to measure immigrant school gaps (differences in scores between immigrants and natives) in relation to various potentially correlated factors. Results show that negative gaps are concentrated in the European Union; in the South, they are mainly correlated with school…

International comparisons reveal that lower-secondary-level students in Austria perform below the OECD mean in science. Guided by the search for remedies and improvements in science teaching, this study investigates whether cross-age peer tutoring is an appropriate method for teaching physics. A modern and concise definition of peer tutoring is…

In this paper, we try to unravel some of the unintended and intended academic effects associated with post-Soviet educational reforms by focusing on three cases: Estonia, Latvia and Russia. We have chosen this comparison because a unique "natural experiment" in the three countries allows us to compare the changing academic performance on…

The present study aimed to identify the role of both student- and school-level characteristics in primary school students' achievement in the science curriculum. As societies become more culturally and linguistically diverse, many students enter the classroom with a home language that is different from the language of instruction used at school.…

This article reports analysis of data collected from a quasi-experimental study in 2 Canadian late French immersion science classes. We examine if, how, and when the first language (L1) is used when students in the first years of their second language learning talk about complex science concepts. We compare differences in groups following a…

Background: The Trends in International Mathematics and Science Study (TIMSS) assesses the quality of the teaching and learning of science and mathematics among Grades 4 and 8 students across participating countries. Purpose: This study explored the relationship between positive affect towards science and mathematics and achievement in science and…

The effectiveness of various strategies for educating the growing U.S. population of English language learners (ELLs) has attracted a great deal of controversy. Bilingual education theory posits that retention and continued development of native language (L1) skills facilitate academic achievement through two mediating mechanisms. First, L1…
