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…

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…

Purpose: The purpose of this study was to determine if a direct, explicit method of teaching vocabulary with the Vocabulary Scenario Technique -- General Education 16 Encounter (VSTGE16) protocol would yield gains in the vocabulary knowledge of fourth grade students in a general education classroom. Two research questions examined whether fourth…

Two single-case studies examined the effects of a vocabulary intervention on K-second grade Deaf or Hard-of-Hearing (DHH) children's vocabulary learning. The intervention consisted of (a) explicit instruction that included fast mapping, and drill and practice games and (b) in-context activities that included book reading, conceptual activities,…

Purpose: The current study compared the effects of direct instruction versus indirect exposure on multiple aspects of novel word learning for children with developmental language disorder (DLD) and children with typical language development (TLD). Method: Participants included 36 children with DLD and 45 children with TLD. All children were in the…

The present study explores lexical collocations and their relation to speaking proficiency of Taiwanese EFL college students learning English for academic purposes (i.e., EAP). The data is obtained from 92 English majors at a national university of science and technology in southern Taiwan. The results show that: (a) direct collocation instruction…

In this cluster randomized control trial study, the authors explored the efficacy of an intervention designed to improve second-grade English learners' knowledge of challenging, high-utility English vocabulary. The authors also examined whether the intervention had a differential effect on content words that differ on two attributes (cognate…

The research literature well establishes that adverse conditions, such as poverty, can affect children's cognitive development and academic achievement. Educators are challenged to translate these understandings into instructional practices grounded in research that best meet the needs of students, especially students living in poverty who are at…

Several researchers have advocated explicit instruction of vocabulary in order to help students improve their reading comprehension, especially low-achieving readers who need to "catch-up" to their age peers. Very few studies, however, have attempted to compare the time efficiency of direct instruction to its alternatives. In this…

The present study examined the effect of different vocabulary instruction methods on EFL learners' vocabulary learning and retention. Elementary and advanced EFL learners (N = 120), selected through convenience sampling, were randomly assigned to three conditions (i.e., six groups for the two levels). The learners in the explicit group received…

In the context of an on-going project emphasising the centrality of speaking and listening in the primary curriculum, the present article turns to vocabulary development: to the wide differences characterising primary age children in this regard, to their consequent unequal access to the wider curriculum, and to means by which such deficiencies…

There are multiple pathways for students with and without disabilities to learn new vocabulary terms. However, the number of empirically tested and validated multimedia options is surprisingly limited. In this study, researchers tested a commercially available app (InferCabulary) to evaluate the impact on vocabulary performance of fifth-grade…

This study aimed to provide professional development in vocabulary instructional practices and analyze the impact on student achievement. This one group pretest-posttest research design study evaluated the effectiveness of direct vocabulary instruction on eighth-grade students' academic achievement, identified the academic achievement gained in…

This research study emphasized the importance of explicit instruction and repeated exposure to the target vocabulary for effective reception and production of new words among the second language learners of English. The purpose of the study was to examine the efficacy of the researcher-created supplementary for the prescribed set of vocabulary in…

Purpose: Many preschoolers, especially those from low-income households, would benefit from instruction to enrich their vocabulary and language repertoires. Yet, explicit instruction of vocabulary and language skills generally occurs infrequently in early childhood education settings. This study investigated the additive effects of teacher-led,…
