This study aimed to examine verbal behaviors within communicative interactions at the teacher/classroom level among second-grade classrooms that differ in socioeconomic status (SES) backgrounds. Investigators recorded and examined language use across instructional periods for 38 second-grade classrooms. Teachers' communication behaviors were…

This study examined how teachers and paraprofessionals in 126 kindergarten-second grade general and special education classrooms talked with their 194 students with autism, and further, how individual student characteristics in language, autism symptoms, and social abilities influenced this talk. Using systematic observational methods and factor…

This study aimed to describe 2nd-grade teachers' use of different forms of praise during English Language Arts (ELA) instruction and examine if teacher characteristics were associated with differences in the use of different types of praise. Investigators recorded 2nd-grade teachers' language use during randomly selected, 15-min excerpts (n = 912)…

The distinctive features of the Arabic language and orthography offer opportunities to investigate multiple word characteristics at the item level. The aim of this paper was to model differences in word reading at the item level among 3rd grade native Arabic-speaking children (n = 303) using cross-classified generalized random-effects (CCGRE)…

This study aimed to examine language at the teacher/classroom level among second-grade classrooms that differ in socioeconomic backgrounds. Measures of teachers' vocabulary input across the school day throughout the school year were examined. There was a significant difference in the proportion of academic word use between classes that differed in…

In this large-scale study of students from Title 1 schools (N = 14,773), we used multiple-group latent change score (LCS) modeling to investigate the developmental relations between vocabulary knowledge and reading comprehension in students with a school-identified learning disability (LD; n = 627) and typically developing students (n = 14,146).…

The primary aims of this study were twofold: (a) to describe average change in the written narrative performance of second grade students from the fall and spring of the school year and (b) examine patterns of individual growth to test for Matthew effects. Participants included 299 children in second grade. Microstructural measures were derived…

We examined how raters and tasks influence measurement error in writing evaluation and how many raters and tasks are needed to reach a desirable level of 0.90 and 0.80 reliabilities for children in Grades 3 and 4. A total of 211 children (102 boys) were administered three tasks in narrative and expository genres, respectively, and their written…

The present study employed data simulation techniques to investigate the 1-year stability of alternative classification schemes for identifying children with reading disabilities. Classification schemes investigated include low performance, unexpected low performance, dual-discrepancy, and a rudimentary form of constellation model of reading…

This randomized controlled experiment compared the efficacy of two response-to-intervention (RTI) models--typical RTI and dynamic RTI--and included 34 first-grade classrooms (n = 522 students) across 10 socioeconomically and culturally diverse schools. Typical RTI was designed to follow the two-stage RTI decision rules that wait to assess response…

The purpose of this study was to examine the interplay between basic numerical cognition and domain-general abilities (such as working memory) in explaining school mathematics learning. First graders (N = 280; mean age = 5.77 years) were assessed on 2 types of basic numerical cognition, 8 domain-general abilities, procedural calculations, and word…

This study investigated the effectiveness of combining enhanced classroom instruction and intense supplemental intervention for struggling readers in first grade. Further, it compared two supplemental interventions derived from distinct theoretical orientations, examining them in terms of effects on academic outcomes and whether children's…

Entry-level kindergartners in classrooms from five middle class school districts were given a test of letter identification and children who scored at or below the 30th percentile on the test were classified as "at risk" for early reading difficulties. Half of these children were randomly assigned to a project-based intervention condition where…
