This meta-analysis included 27 empirical studies to explore the effectiveness of robot-assisted language learning (RALL) as well as the moderating effects of a number of variables. The comparison of 64 effect sizes from 2,637 participants indicated significant variability between the independent samples. The overall results showed that the…

This study used a meta-analytic structural equation modeling approach to build extended versions of the simple view of reading (SVR) model in second and foreign language (SFL) learning contexts (i.e., SVR-SFL). Based on the correlation coefficients derived from primary studies, we replicated and integrated two previous extended meta-analytic SVR…

We examined the relation of morphological awareness with language and literacy skills, namely phonological awareness, orthographic awareness, vocabulary, word reading, spelling, text reading fluency, and reading comprehension. We also examined potential moderators of the relations (grade level, orthographic depth of language, receptive vs.…

This meta-analysis synthesized recent research on strategy instruction (SI) effectiveness to estimate SI effects and their moderators for two domains: second/foreign language and self-regulated learning. A total of 37 studies (47 independent samples) for language domain and 16 studies (17 independent samples) for self-regulated learning domain…

The effectiveness of bilingual programs for promoting academic achievement of language minority children in the United States has been examined in six meta-analyses. The present meta-analytic study investigates this topic for the first time in the European context. Thorough literature searches uncovered 101 European studies, with only 7 meeting…

Sixteen meta-analyses were conducted to examine relations of typically developing bilingual immigrant-background children's oral language proficiency in their first and second language with the school outcomes of early literacy (k = 41), reading (k = 61), spelling (k = 9), mathematics (k = 9), and academic achievement (k = 9). Moderate to strong…

To facilitate second language learning, it has become increasingly popular to use a second language as the medium of instruction for content subjects for majority language students. Although numerous research studies have shown the advantages of such kind of programs in North America and Europe, those investigating English as the Medium of…

This article systematically reviews the cost study literature as it relates to the treatment of English language learners (ELLs). Despite the substantial number of costing out studies that have been conducted over the past several decades, the school finance literature has failed to focus on ELLs--the fastest growing segment of the school-age…

Including English language learners (ELLs) in large-scale assessments raises questions about the validity of inferences based on their scores. Test accommodations for ELLs are intended to reduce the impact of limited English proficiency on the assessment of the target construct, most often mathematic or science proficiency. This meta-analysis…

Meta analysis results were compared with a traditional review of bilingual education program effectiveness. When controlled for methodological inadequacies, participation in bilingual education programs consistently produced differences favoring bilingual education. The methodological inadequacies in the synthesized studies highlights the need for…
