Digital reading facilitates L2 development by allowing anytime-anywhere learning with various digital resources. Although there has been increasing research exploring the role of digital reading on L2 vocabulary learning, synthesized evidence regarding the overall facilitating power of digital reading is still lacking. This meta-analysis…

This multiple paper dissertation addressed several issues revolving around the estimation of effect sizes for computer-based scaffolding in problem-centered STEM education. STEM jobs are outpacing all other jobs and STEM workers are expected to solve complex problems. However, students often struggle with complex problem activities. Research on…

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…

Standardized reading assessments are often used as an admissions criterion for college admittance, however, the relationship and predictive validity of reading assessments to academic achievement remains in question. Through a quantitative review of the literature, we conducted a meta-analysis to examine how well performance on college reading…

Reading comprehension assessments are used for postsecondary course placement and advising, and they are components of college entrance exams. Therefore, a quantitative understanding of the relationship between reading comprehension assessments and postsecondary academic achievement is needed. To address this need, we conducted a meta-analysis to…

In this meta-analysis, we examined whether children identified with reading difficulties (RD) evidence writing difficulties. We included studies comparing children with RD with (a) typically developing peers matched on age (k = 87 studies) and (b) typically developing younger peers with similar reading capabilities (k = 24 studies). Children…

Inequality in reading outcomes is perhaps the single greatest social justice issue faced by school psychologists, and school psychologists need a better understanding of reading theory and its application to intervention to better combat the important issue. The present study examined the active view of reading (AVR; Duke & Cartwright, 2021),…

The aim of this study is to investigate the relationship between frequency and language acquisition from many perspectives including implicit and explicit instruction, frequency effects on morpheme acquisition in L2, the relationship between frequency and multi-word constructions, frequency effects on phonetics, vocabulary, gerund and infinitive…

In recent years there has been a growing interest to incorporate hypertext glosses into L2 reading materials and accordingly, it has provoked researchers to uncover to what extent and under which moderator variables a specific type of gloss yields more effective outcomes than other types of glossing. The present meta-analysis attempts to examine…

There is a general consensus that writing is a challenging task for students with learning disabilities (LD). To identify more precisely the extent and depth of the challenges that these students experience with writing, the authors conducted a meta-analysis comparing the writing performance of students with LD to their typically achieving peers.…

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…

Purpose: The purpose of this study was to explore the literature on predictors of outcomes among late talkers using systematic review and meta-analysis methods. We sought to answer the question: What factors predict preschool-age expressive-language outcomes among late-talking toddlers? Method: We entered carefully selected search terms into the…

Child gender has been proved to affect toddlers'/children's language development in several studies, but its effect was not found to be stable across different ages or various aspects of language ability. The effect of gender on toddler's, children's and adolescents' language ability was examined in the present meta-analysis of ten Slovenian…

A systematic review of research on oral language assessments for four-to-eight-year- old children was undertaken to support a six-year action research project aimed toward co-creating classroom oral language assessment tools with teachers in northern rural and Indigenous Canadian communities. Through an extensive screening process, 10 studies were…

Although an abundant literature documents preliterate children's word learning success from shared storybook reading, a full synthesis of the factors which moderate these word learning effects has been largely neglected. This meta-analysis included 38 studies with 2,455 children, reflecting 110 effect sizes, investigating how reading styles, story…
