Vocabulary instruction is a critical component of language and literacy lessons, yet few studies have examined the nature and extent of vocabulary activities in early elementary classrooms. We explored vocabulary activities during reading lessons using video observations in a sample of 2ndand 3rd-grade students (n = 228) and their teachers (n =…

This article addresses approaches to differentiating instruction to meet the needs of students whose literacy needs, interests, and strengths vary widely. This article was designed to support classroom teachers who understand the importance of differentiating instruction, but are unsure of how best to design and implement differentiation within…

Purpose: In this study, we examined (a) whether children who spoke Nonmainstream American English (NMAE) frequently in school at the beginning of 1st grade increased their use of Mainstream American English (MAE) through the end of 2nd grade, and whether increasing MAE use was associated with (b) language and reading skills and school context and…

Purpose: This study had 2 principal aims: (a) to examine whether children who spoke Nonmainstream American English (NMAE) frequently in school at the end of kindergarten increased their production of Mainstream American English (MAE) forms by the end of first grade, and (b) to examine concurrent and predictive relations between children's NMAE use…

The associations among second- and third-grade students' content-area knowledge, vocabulary, and reading gains and the science instruction they received were examined in this exploratory longitudinal study. We also asked whether there were child characteristics x instruction interaction effects on students' content-area literacy. Second graders (n…

Classmates' academic skill level (peer effects) is emerging as an important predictor of individual student achievement, particularly in the early grades. However, less is known about the influence of peer effects with regard to classmates' self-regulation skills and whether they are associated with students' academic gains. Examining this is the…

There is accumulating correlational evidence that the effect of specific types of reading instruction depends on children's initial language and literacy skills, called child characteristics x instruction (CxI) interactions. There is, however, no experimental evidence beyond first grade. This randomized control study examined whether CxI…

Too many children fail to learn how to read proficiently with serious consequences for their overall well-being and long-term success in school. This may be because providing effective instruction is more complex than many of the current models of reading instruction portray; there are Child Characteristic x Instruction (CXI) interactions. Here we…

The purpose of this cluster-randomized control field trial was to examine whether kindergarten teachers could learn to differentiate classroom reading instruction using Individualized Student Instruction for Kindergarten (ISI-K) and to test the efficacy of differentiation on reading outcomes. The study involved 14 schools, 23 ISI-K (n = 305…

Recent studies have observed connections among teachers' depressive symptoms and student outcomes; however, the specific mechanisms through which teachers' mental health characteristics operate in the classroom remain largely unknown. The present study used student-level observation methods to examine the relations between third-grade teachers' (N…

This study explored the spelling skills of African American second graders who produced African American English (AAE) features in speech. The children (N = 92), who varied in spoken AAE use and word reading skills, were asked to spell words that contained phonological and morphological dialect-sensitive (DS) features that can vary between AAE and…

We examined the effect of individualizing student instruction (ISI; N = 445 students, 46 classrooms) on first graders' self-regulation gains compared to a business-as-usual control group. Self-regulation, conceptualized as a constellation of executive skills, was positively associated with academic development. We hypothesized that the ISI…

This study describes a second-grade science curriculum designed to individualize student instruction (ISI-Science) so that students, regardless of initial science and literacy skills, gain science knowledge and reading skills. ISI-Science relies on the 5-E Learning Cycle as a framework and incorporates flexible, homogeneous, literacy skills-based…

Retention is a frequently used strategy to support children who are struggling academically. However, the strategy is costly, and research findings with regard to positive outcomes are mixed. This study examined whether efficacious reading instruction might reduce rates of retention in first grade. We also evaluated the reading instruction the…

This study investigated the psychometrics of the "Diagnostic Evaluation of Language Variation-Screening Test" (DELV-S) test using confirmatory factor analysis, item response theory, and differential item functioning (DIF). Responses from 1,764 students in kindergarten through second grade were used in the study, with results indicating…
