To identify effective methods for boosting incidental vocabulary learning, this study examines the impacts of two tools--bimodal presentation (BP) and lexical elaboration (LE)--on vocabulary acquisition through repeated encounters with target words during meaning-focused reading. In a quiet and comfortable place conducive to full concentration on…

A meta-analysis of group studies and single-case design studies was conducted to examine the effectiveness of vocabulary instruction on vocabulary learning and reading comprehension for English Learners. Overall estimates indicate that vocabulary instruction promoted vocabulary learning and reading comprehension. The mean effect for vocabulary…

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…

In this manuscript we show how read alouds can significantly enrich student vocabulary and comprehension by demonstrating enhancements that will foster student learning and language development. We anchor our examples to empirical evidence demonstrating that the content of a read aloud (i.e., the what we teach) as well as the quality of the…

The current study examined the relation between the amount of literacy instruction and student reading achievement (word reading and reading comprehension), using data from 927 students and their 189 teachers from Grades 1 to 3 in the US. Literacy instruction was observed once in the Fall and once in the Spring each year from two projects. We…

Conceptual knowledge goal (CKG) is a typical component of outcome-based learning. However, the contribution of CKG to poor readers' reading comprehension development remains unclear. Following the suggestion of the Simple View of Reading theory for the poor reader category, the current study recruited 90 poor decoders (PD), 76 poor comprehenders…

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…

Underpinned by constructivist learning theory (Feuerstein's theory of mediated learning experience) and the cloud computing model, an experiment was conducted to examine the differences between the control and experimental groups regarding the linear combinations of tool mediation on students' reading comprehension and vocabulary learning skills.…

In this pre-registered meta-analysis, we investigated the effectiveness of morphology instruction on literacy outcomes for primary school children in English-speaking countries. We were interested in overall reading and spelling outcomes, but we also looked separately at results for trained and untrained words in order to determine whether there…

Good readers use various comprehension strategies to understand texts. However, many students lack knowledge on how to purposefully and effectively use text comprehension strategies. In this experimental study, the effectiveness of teaching text comprehension strategies on vocabulary and text comprehension at literal, inferential and evaluative…

We report on a meta-analysis designed to test the theory that instruction that involves direct teaching of academic vocabulary and teaching strategies to determine the meaning of unknown words develops students' abilities to infer new words' meanings and builds students' overall vocabulary knowledge. We meta-analyzed 39 experimental and…

Drawing on sociocultural theory, and multiple empirical studies conducted on the effectiveness of scaffolding on second or foreign language learning, the authors investigated the application of various forms of scaffolding (i.e., teacher versus peer-scaffolding) on EFL learners' incidental vocabulary learning and reading comprehension performance…

With the growing interest in integrating information and communication technology in the EFL classroom, the present study investigated the impact of electronic first language (L1) translations and second language (L2) definition glosses on incidental vocabulary learning and retention among Moroccan EFL learners. In total, 172 first-year university…

This study addressed the effects of Strategies for Teaching Reading, Information, and Vocabulary Effectively (STRIVE), a distributed professional development (PD) model designed to help teachers implement reading comprehension and vocabulary practices in fourth grade social studies classes. Schools (n = 81 schools, n = 235 teachers, n = 4,757…

The debate over the science of reading has focused primarily on decoding (i.e., connecting letters and sounds to read words) and whether to use phonics to teach it. However, research on reading has included much more than decoding. Language comprehension, which allows readers to derive meaning from text, is an equally critical component of…
