Purpose: Phonological awareness (PA), the awareness of sounds in spoken words, is strongly linked to reading outcomes. However, there is an ongoing debate regarding the effectiveness of PA instruction without including print (i.e. PA without exposure to words or letters). Specifically, is PA-only instruction just as effective in improving reading…

Purpose: Research on how much early phonemic awareness (PA) instruction is optimal has produced inconclusive answers. We conducted a nonlinear meta-analysis to estimate the optimal cumulative dosage of early PA instruction on PA outcomes with an associated maximum effect size in preschool through first-grade students. Method: Sixteen experimental…

The purpose of this meta-analysis was to assess the overall effects of automaticity training of fundamental literacy component skills (i.e., letter names/sounds, individual words) on reading fluency and comprehension. Another purpose was to assess if the effects of automaticity training varied for reading fluency and comprehension. We identified…

The linguistic, mathematical, social-emotional, and cognitive precursor competencies are important predictors of learning success already at kindergarten age. A systematic analysis of the state of research on the actual interrelationships of the focused precursor competencies brings together results of a meta-analysis. The literature search…

Purpose: The present meta-analysis sought to investigate the effects of phonemic awareness instruction provided to children suspected of having a reading disability. Method: Seven databases were systematically searched, and 1,643 unique manuscripts were reviewed for inclusion. Data were extracted from 138 included manuscripts to evaluate the use…

Thousands of educational apps are available to students, teachers, and parents, yet research on their effectiveness is limited. This meta-analysis synthesized findings from 36 intervention studies and 285 effect sizes evaluating the effectiveness of educational apps for preschool to Grade 3 children and the moderating role of methodological,…

This article presents the results of a meta-analysis of the effects of school-based interventions for improving disability awareness and attitudes towards disability of students without disabilities in Kindergarten through secondary school grades in the Republic of Korea (South Korea). A total of 20 studies published between 2001 and 2017 were…

Social-Emotional Learning (SEL) programs are school-based preventive interventions that aim to improve children's social-emotional skills and behavioral development. Although meta-analytic research has shown that SEL programs can improve academic and behavioral outcomes in the short term, few studies have examined program effects on receipt of…

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…

To determine whether formative writing assessments that are directly tied to everyday classroom teaching and learning enhance students' writing performance, we conducted a meta-analysis of true and quasi-experiments conducted with students in grades 1 to 8. We found that feedback to students about writing from adults, peers, self, and computers…

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…

A synthesis and meta-analysis of the extant research on the effects of storybook read-aloud interventions for children at risk for reading difficulties ages 3 to 8 is provided. A total of 29 studies met criteria for the synthesis, with 18 studies providing sufficient data for inclusion in the meta-analysis. Read-aloud instruction has been examined…

The authors reviewed all peer-reviewed studies with participants from preschool to Grade 8 for this meta-analysis of morphological interventions. They identified 22 applicable studies. Instructional effects (Cohen's d) were averaged by linguistic outcome categories (morphological sublexical, non-morphological sublexical, lexical, and supralexical)…

This meta-analysis assesses the effectiveness of volunteer tutoring programs for improving the academic skills of students enrolled in public schools Grades K-8 in the United States and further investigates for whom and under what conditions tutoring can be effective. The authors found 21 studies (with 28 different study cohorts in those studies)…

This meta-analysis examines to what extent interactive storybook reading stimulates two pillars of learning to read: vocabulary and print knowledge. The authors quantitatively reviewed 31 (quasi) experiments (n = 2,049 children) in which educators were trained to encourage children to be actively involved before, during, and after joint book…
