This article is an expanded version of my presentation to Division 15 (Educational Psychology) of the American Psychological Association for the Career Achievement Award for Distinguished Psychological Contributions to Education in 2019. It provides an overview of research conducted by colleagues and I that examined the following four topics: (a)…

The coronavirus disease 2019 (COVID-19) pandemic and the sudden cancellation of in-class instruction for many students around the world presented an unprecedented disruption in children's education. As the COVID-19 pandemic took form, multiple concerns were raised about the potential negative impact on students' learning. The current study…

Reading in English is an essential skill that emergent bilingual students in the United States (U.S.) must master to be successful in school and to fully take advantage of the affordances reading in English offers. The current meta-analysis examined the extent to which reading instruction improved English reading outcomes for preschool to grade 12…

Until children can produce letters quickly and accurately, it is assumed that handwriting disrupts and limits the quality of their text. This investigation is the largest study to date (2596 girls, 2354 boys) assessing the association between handwriting fluency and writing quality. We tested whether handwriting fluency made a statistically unique…

The current study examined how Chinese characters were taught by primary grade teachers in Macao during online instruction resulting from the COVID-19 pandemic (i.e., emergency remote instruction). A random sample of 313 first to third grade teachers in public and private schools were surveyed about their instructional practices. Most teachers…

This study examined the intrinsic, extrinsic, and self-regulatory motives for writing and writing achievement of three groups of third- to fifth-grade students in an urban school district: (a) 189 emergent bilingual students receiving services for English language development (ELD); (b) 374 reclassified bilingual students who had exited ELD…

Two hundred fifty-four intermediate-grade teachers (88% female) in urban public schools in Chile indicated how frequently they made writing instructional adaptations for their weakest writers, which included students with learning and other disabilities. A majority of teachers reported making the following adaptations for their weakest writers at…

A sample of 1049 Norwegian teachers in grades 1-3 were surveyed about how they taught writing as well as their preparation and efficacy to do so. Although there was moderate variability in their response to survey items, most teachers provided students with a multi-faceted writing program. Teachers indicated students typically spent 20 min a day…

This meta-analysis examined if students writing about content material in science, social studies, and mathematics facilitated learning (k = 56 experiments). Studies in this review were true or quasi-experiments (with pretests), written in English, and conducted with students in Grades 1 to 12 in which the writing-to-learn activity was part of…

In this meta-analysis, we examined whether children classified with specific language impairment (SLI) experience difficulties with writing. We included studies comparing children with SLI to (a) typically developing peers matched on age (k = 39 studies) and (b) typically developing younger peers with similar language capabilities (k = six…

Conducting focus groups with target audiences to assess user needs is a critical step in the process of designing and developing a web-based writing environment. This descriptive study examined focus group data gathered to address two questions: First, do data from focus groups affirm and expand our understanding of writing and writing development…

In today's world, writing is an essential skill. At school, writing is often used to gauge students' understanding of content material as well as to promote the learning of it. Students with learning disabilities (LD) and those at risk for writing difficulties experience considerable difficulty with almost every aspect of writing. The field of LD…

If students are to be successful in school, at work, and in their personal lives, they must learn to write. This requires that they receive adequate practice and instruction in writing, as this complex skill does not develop naturally. A basic goal of schooling then is to teach students to use this versatile tool effectively and flexibly. Many…

This meta-analysis examined if students' writing performance is improved by reading interventions in studies (k = 54 experiments; 5,018 students) where students were taught how to read and studies (k = 36 investigations; 3,060 students) where students' interaction with words or text was increased through reading or observing others read. Studies…

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.…
