Longitudinal models typically emphasize between-person predictors of change but ignore how growth varies "within" persons because each person contributes only one data point at each time. In contrast, modeling growth with multi-item assessments allows evaluation of how relative item performance may shift over time. While traditionally…

The purpose of this study was to examine the effects of a rich vocabulary intervention on the comprehension and vocabulary learning of third-grade students with language learning disorders (LLD). The study used a repeated acquisition design (RAD), a single case design involving the repeated delivery of a vocabulary intervention on different sets…

Although research provides ample evidence of teaching methods that facilitate students' learning of specific word meanings, the potential of instruction to impact students' general vocabulary knowledge has remained an unanswered question. This article reports on a three-year formative experiment that developed, implemented, and tested a long-term,…

This study evaluated the feasibility of the Knowledge, Language, and Inquiry (K.L.I.) intervention, designed to support Grades 3-5 multilingual students classified as English learners (ML-ELs) in building content knowledge, language skills, and reading comprehension through inquiry-based small-group instruction. Feasibility was examined across…

The purpose of this study was to examine the effects of extended vocabulary instruction on the expressive vocabulary of two third-grade students with vocabulary deficits. According to the Common Core State Standards Initiative (n.d.), students in third grade should be able to determine the meaning of unknown and multiple-meaning words and phrases…

This study aimed to determine the dimensionality of morphological knowledge by examining different sources of variance. According to the Morphological Pathways Framework ("Levesque et al., Journal of Research in Reading," 44, 10-26, 2021), morphological awareness, morphological analysis and morphological decoding are related, but…

Schema instruction improves word-problem solving for students with mathematics difficulty (MD; e.g., Powell et al., 2015); however, prior research suggests that students need word-problem-specific language comprehension in addition to schema knowledge to build word-problem models (Fuchs et al., 2015, 2018). Students have general word knowledge…

More research attention and implementation support are needed for mathematics intervention as student achievement in this area continues to fall below desirable levels. Incremental rehearsal is an intervention to help students build reading, vocabulary, and math fluency. Research supports the use of incremental rehearsal for improving math fact…

Students in grades 3-6 need to use increasingly sophisticated comprehension skills and strategies as they read and build knowledge across disciplinary content areas. Grounded in research, this book presents effective practices for integrating literacy instruction with literature, science, and social studies. Chapters address text selection,…

Purpose: The purpose of this study was to examine if word reading and vocabulary are reciprocally related. Method: We followed a sample of 172 English-speaking Canadian children (82 girls, 90 boys; M[subscript age] = 75.87 months at the first measurement point) from the beginning of Grade 1 until the beginning of Grade 3 and assessed them three…

This action research study aimed to improve reading with understanding in a lower primary classroom in Fiji. Five emergent readers were selected through an examination of class running records. Peer observation, student worksheets, and class running records were utilized to collect data. The data analysis revealed that when teachers implement…

The Common Core State Standards emphasize the need for U.S. students to read complex texts. As a result, the level of word complexity for primary-level texts is important, particularly the dimensions of and changes in complexity between first grade and the important third-grade high-stakes testing year. In this study, we addressed word complexity…

Storytelling is a well-established literary practice in language classrooms. However, approaches influencing its effectiveness and efficiency have rarely been investigated. This study compared the effects of three storytelling approaches on the vocabulary acquisition and response patterns of third-grade students of English as a foreign language…

Purpose: The purpose of this study was to investigate the effects of a vocabulary intervention delivered by teachers collaborating with speech-language pathologists (SLPs) in the classroom as compared with teachers in a noncollaborating condition. Method: This quasi-experimental study employed a collaboration treatment condition (n = 2…

Background: Early intervention for children identified as late talkers (LTs) at the age of 24 months is still a controversial issue in research and clinical routine. Previous studies have shown inconsistent results regarding predictors of early lexical deficits on school-age outcomes of late-talking toddlers. Methods: In a five-wave follow-up…
