This study examined the impact of the Institute for Multi-Sensory Education's (IMSE) Orton-Gillingham Plus (OG+) program on early literacy outcomes in a Title I school district in Michigan during the 2022-2023 school year. Learning Experience Design (LXD) Research employed a quasi-experimental study design with 397 kindergarten and first-grade…

This study examines the effectiveness of scaling up a vocabulary intervention, pre-K-first grade, using a structured adaptation of the World of Words that allowed teachers some autonomy over its implementation. The purpose was to determine whether such an adaptation could maintain fidelity and promote positive child outcomes. Classrooms (pre-K…

Students most at risk for reading-related disabilities frequently struggle with word recognition and oral language, including, in the earliest grades, specific skills related to phonological awareness and vocabulary. Classroom teachers' delivery of high-quality differentiated supplemental instruction may promote reading acquisition for these…

Background/Context: Reading achievement declined drastically during the COVID-19 pandemic (Bailey et al., 2021). One report suggests more than one-third of fourth-grade students cannot read at a basic level and access to effective literacy instruction is particularly limited for minority students and students with learning disabilities (Ellis et…

It is well-documented that there is a strong relationship between vocabulary and reading comprehension in school-age children. Limited vocabulary knowledge can impact a student's reading achievement, as may be the case for school-age English Learners (ELs). This study aims to analyze the role of vocabulary in predicting reading comprehension…

We evaluated the long-term effects of a supplemental, small-group kindergarten vocabulary intervention in fall and spring of first grade and winter of second grade. Participants included students from two studies, an initial efficacy study and a subsequent replication study, identified as at risk for language and learning difficulties, who were…

This study investigated the effect of the digital Down Syndrome LanguagePlus (DSL+) intervention on vocabulary outcomes through a school-delivered randomized controlled trial. A national sample of first graders with Down syndrome from 91 schools was allocated to an intervention group (n = 50), which received daily intervention for 15 weeks, or a…

Teachers' implementation of differentiated supplemental instruction is critical to help students with or at risk for reading-related disabilities acquire early reading and vocabulary skills. This study represents an initial investigation of whether classroom teachers' intervention fidelity (exposure, adherence, and quality) of targeted reading…

The role of children's receptive vocabulary knowledge in word and nonword reading (decoding) in an orthographically transparent language is debated. Moreover, we have little understanding of how the role of vocabulary might differ between monolingual children and bilingual children from immigrant families (or language minority bilingual children…

There is growing recognition of the need to end the debate regarding reading instruction in favor of an approach that provides a solid foundation in phonics and other underlying language skills to become expert readers. We advance this agenda by providing evidence of specific effects of instruction focused primarily on the written code or on…

This article reports on an exploratory study on developing and adopting a 'Virtual Go Mode' feature embedded in a mobile vocabulary learning app, VocabGo, to enhance students' vocabulary learning engagement. Distinguished from other virtual reality (VR) or augmented reality (AR) applications, the Virtual Go Mode is designed for students to…

This study was conducted with the following objectives: 1) to develop digital technology that supports learning in children with disabilities; 2) to test the effectiveness of digital technology used in children's learning. The sample selected to study the current context of and needs of digital technology consisted of a group of 46 teachers and…

Learning academic vocabulary is a crucial task for all students, but especially challenging for students with speech, language, and communication needs (SLCN) and those who are multilingual. Following a participatory research strategy, we analyze whether iconic gestures can be integrated in teaching routines in an inclusive elementary school and…

This paper presents the results of a quasi-experimental study examining the effectiveness of Amplify Reading, a digital supplemental literacy curriculum that students play independently at school or at home, in improving student literacy outcomes as measured by end of year Dynamic Indicators of Basic Early Literacy Skills (DIBELS) Next for…

Purpose: Our 1-year longitudinal study tracked the development of cognate awareness among second (L2) and third language (L3) learners of French in French immersion in Grades 1 and 2 to explore the impact of orthographic overlap and cognate status (true vs. false) on children's ability to recognize cognate relationships. We also assessed the…
