In this pre-registered meta-analysis, we investigated the effectiveness of morphology instruction on literacy outcomes for primary school children in English-speaking countries. We were interested in overall reading and spelling outcomes, but we also looked separately at results for trained and untrained words in order to determine whether there…

With the escalating growth of English language learners (ELLs) worldwide, educational technology has been identified as an important learning tool with significant potential to support second language literacy development. This review examined the effectiveness of technology-integrated literacy instruction in the classroom context for ELLs in…

This paper is a quantitative synthesis of research on home literacy environment (HLE) and children's English as a second language (ESL) learning outcomes through a meta-analysis of 18 articles in kindergarten, primary, and secondary school students (N = 4401) carried out between 2000 and 2018. It examines the associations between HLE factors and…

Teacher coaching has emerged as a promising alternative to traditional models of professional development. We review the empirical literature on teacher coaching and conduct meta-analyses to estimate the mean effect of coaching programs on teachers' instructional practice and students' academic achievement. Combining results across 60 studies that…

Reading and writing are critical to students' success in and outside of school. Because they draw on common sources of knowledge and cognitive processes, involve meaning making, and can be used conjointly to accomplish important learning goals, it is often recommended that reading and writing should be taught together. This meta-analysis tested…

Reading Recovery is one of the most researched literacy programs worldwide. Although there have been at least 4 quantitative reviews of its effectiveness, none have considered all rigorous group-comparison studies from all implementing nations from the late 1970s to 2015. Using a hierarchical linear modeling (HLM) v-known analysis, we examined if…

Background: For a majority of the world's children, despite substantial increases in primary school enrollment, academic learning is neither occurring at expected rates nor supplying the basic foundational skills necessary to succeed in the 21st century. The significant lag in academic achievement tells us that simply making formal education…

The purpose of this study is to examine the effects of morphological instruction on language and literacy outcomes by synthesizing 92 standardized mean differences (d) from 30 independent studies. Findings show a moderate overall effect of morphological instruction ([d-bar] = 0.32), suggesting that children receiving morphological instruction…

Background: Many countries rely on immigrants for population growth and to maintain a skilled workforce. However, many such immigrants face literacy-related barriers to success in education and in the labour force. Aims: This meta-analysis reviews experimental and quasi-experimental studies to examine strategies for teaching English literacy to…

The findings of a meta-analysis of the effect of reading instruction on the reading skills of students with or at risk of behavioral disorders (BD) are reported. The goal of the synthesis was to extend the work of Coleman and Vaughn by (a) detailing independent variables and outcome measures for each study, (b)including studies sampling from…

Alphabet knowledge is a hallmark of early literacy and facilitating its development has become a primary objective of preschool instruction and intervention. However, little agreement exists about how to promote the development of alphabet knowledge effectively. A meta-analysis of the effects of instruction on alphabet outcomes demonstrated that…

Goal: Educators believe that parents can help their children learn to read. But what evidence supports this belief? And if parent involvement does matter, what kinds of parent involvement are most efficient? The goal of this report was to review the scientific literature on parent involvement in the acquisition of reading from kindergarten to…
