Gough and Tunmer's (1986) simple view of reading (SVR) proposed that reading comprehension (RC) is a function of language comprehension (LC) and word recognition/decoding. Braze et al. (2007) presented data suggesting an extension of the SVR in which knowledge of vocabulary (V) affected RC over and above the effects of LC. Tunmer and Chapman…

We investigate the impact of a relatively brief cross-curricular intervention, Word Generation, on middle school students' development of taught academic vocabulary. Students (n = 8382) in forty-four middle schools in three urban districts were randomly assigned to treatment or control conditions. Treatment teachers implemented the program with…

Although the use of literacy coaches is becoming more common, few research studies have shown positive effects of coaching on teacher practices and student achievement. In the current study, a cluster randomized design was used to evaluate usefulness of coaches for teachers of struggling high school students. High schools were randomly assigned…

We conducted a randomized field trial to test an academic vocabulary intervention designed to bolster the language and literacy skills of linguistically diverse sixth-grade students (N = 2,082; n = 1,469 from a home where English is not the primary language), many demonstrating low achievement, enrolled in 14 urban middle schools. The 20-week…

The present study examined the amount, type, and quality of Tier 1 and supplemental reading instruction provided to fourth-grade struggling readers and whether specific elements of instruction predicted growth in reading skills. 110 students identified as having reading difficulty, receiving school-based reading instruction in 22 classrooms…

The present study examined the amount, type, and quality of Tier 1 and supplemental reading instruction provided to 4th-grade struggling readers and whether specific elements of instruction predicted growth in reading skills. In all, 110 students identified as having reading difficulty who were receiving school-based reading instruction in 22…

This article reports on an English for academic purposes course designed following the tenets of content and language integrated learning (CLIL) to address the needs of language minority (LM) high school graduates entering Canadian universities. The language used in and required of post-secondary study is challenging for many LM students,…

This article presents findings from an intervention across sixth and seventh grades to teach academic words to middle school students. The goals included investigating a progression of outcomes from word knowledge to comprehension and investigating the processes students use in establishing word meaning. Participants in Year 1 were two sixth-grade…

This experimental study examined the effectiveness of a text-based reading and vocabulary intervention with self-regulatory supports for 4th graders with low reading comprehension. Students with standard scores on the Gates MacGinitie Reading Test between 1.0 standard deviation (SD) and 0.5 SD below the normative sample were included (N=44) and…

The current study models reader, item, and word contributions to the lexical representations of 39 morphologically complex words for 172 middle school students using a crossed random-effects item response model with multiple outcomes. We report 3 findings. First, results suggest that lexical representations can be characterized by separate but…

In this study, we examined 5th grade students' levels of vocabulary knowledge and syntactic awareness relative to their reading comprehension performance. The aim was to explore the contributions of vocabulary and syntactic awareness as potential sources of reading comprehension difficulty for these readers. Overall, we found that both vocabulary…

Immigrants and the children of immigrants who have completed their schooling in Canadian school settings, commonly referred to as Generation 1.5, are increasingly identified in the research literature as academically at risk due to inadequately developed academic language proficiency and learning strategies. This article describes the design,…

Despite a long-standing awareness of academic language as a pedagogically relevant research area, the construct of academic-language proficiency, understood as a more comprehensive set of skills than just academic vocabulary, has remained vaguely specified. In this study, we explore a more inclusive operationalization of an academic-language…

Word learning can build the high-quality word representations that support skilled reading and language comprehension. According to the partial knowledge hypothesis, words that are partially known, a.k.a. "frontier words" (Durso & Shore, 1991), may be good targets for instruction precisely because they are already familiar. However,…
