Children with developmental language disorder (DLD) served as a test case for determining the role of extant vocabulary knowledge, endogenous attention, and phonological working memory abilities in cross-situational word learning. First-graders (M[subscript age] = 7 years; 3 months), 44 with typical development (TD) and 28 with DLD, completed a…

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,…

Teaching a homograph by using context clues is more effective than just teaching vocabulary separately. The goal of the study reported on here was to teach 12 homographs to d/Deaf and Hard of Hearing (d/Dhh) students in the sixth grade by applying metacognitive skills to understand the meanings and contexts in sentences. A single case design…

Word knowledge acquisition is an incremental process that relies on exposure. As a result, word knowledge can broadly range from recognizing the word's lexical status, to knowing its meaning in context, and to knowing its meaning independent of context. The present study aimed to model incremental word knowledge in 1454 upper primary school…

This study investigates Vietnamese EFL teachers' beliefs and practices regarding oral corrective feedback, exploring and seeking to explain some of the relationships between beliefs and classroom practices. Data were collected in primary schools in Vietnam, and consist of 24 classroom observations and interviews with six teachers. Overall, the…

Early vocabulary knowledge is vital for later reading comprehension and academic success. Studies have found that augmenting explicit teaching of word meanings with nonverbal visual aids, particularly pictures and gestures, assists young learners in building rich lexical representations. Research has focused on the effects of visual supports in…

English language learners (ELLs) lack academic vocabulary knowledge, an essential component that explains much of the persistent achievement gap between students who start schools as ELLs and their monolingual peers. This single-subject experimental design study addressed this issue by focusing on self-regulated vocabulary learning that helps ELLs…

A second language can be learned inside and outside the classroom. In this study we investigated the English and French vocabulary knowledge of 110 Dutch-speaking children (age 10-12), who received 100 hours of instruction in French, whereas their contact with English came from out-of-school exposure only. We examined the role of individual…

Aim: We conducted two separate but related multiple baseline with alternating treatment single-case design studies to investigate the effect of the same reading intervention for students with autism spectrum disorder being implemented under different conditions. Method: We conducted a researcher-implemented study in a public school (Study 1) and a…

While recent studies find that contextual diversity (CD) is a better determinant of visual word recognition than token frequency, there is a dearth of work comparing contextual diversity and token frequency in developing readers. In two sets of character and lexical decision experiments we examined token frequency and contextual diversity effects…

We investigated pictorial versus contextual support effects over and above teaching of definitions on children's word learning and retention as well as the moderating role of reading comprehension. In a between-subject pre-post-retention test control group design, Dutch fourth graders learned concrete and abstract Dutch words. The context group…

Vocabulary is important to reading achievement and overall school success; however, in spite of the research in support of vocabulary instruction, robust vocabulary instruction is lacking in many schools. The purpose of this study was to provide a team of three grade five teachers and an instructional coach with professional development on…

In the digital era, some people must use technology to support their works or even their pleasure time. A game is one of the digital applications for some people to spend their leisure time, including children. However, indirectly, a game also can be an educational tool for children, especially for language. Based on the description, the…

This study examined the optimal learning schedule for second language vocabulary within an authentic classroom setting in Hong Kong. Following a pretest, treatment, delayed posttest design, fifty-two primary school students (Cantonese first language) studied 20 English adjectives over two learning episodes under spaced-short (1-day interval) or…

This study tested how 53 kindergarteners' expressions of depth of vocabulary knowledge and use in novel contexts were related to in-context and out-of-context test formats for 16 target words. Applying multilevel, multi-categorical Logit to all 1,696 test item responses, the authors found that kindergarteners were more likely to express deep…
