Building vocabulary knowledge, especially breadth and depth of word meanings, is a crucial step in assisting students to read and comprehend print independently. A large body of research has documented the low reading achievement levels of a number of Deaf and hard-of-hearing (DHH) students. The goal of the present study was to examine the effects…

There is growing evidence that L2 learners pick up new words while viewing video but little is known about the role of individual differences. This study explores incidental learning after viewing a French documentary containing 15 pseudowords and investigates whether learning is moderated by participants' prior vocabulary knowledge and working…

This study aimed to describe 1-year changes in students' vocabulary in written narratives. Secondary aims included examination of accuracy and the relationship between lexical diversity and achievement. Participants included 749 students in first through eighth grades. Within-subjects 1-year change in diversity, productivity, and accuracy was…

Classic studies of educational media have demonstrated that children can engage in quick, incidental word learning on the basis of a single exposure of a program. Since most words are learned from context, a lingering question has been whether the kind of contextual support affects word learning. Using a within-subjects design this study examined…

Drawing on research-informed principles for primary-grade vocabulary instruction, the authors developed a series of engaging vocabulary units for a first-grade class. The units, focused on the explicit teaching of target words and the efficient highlighting of larger sets of semantically related words, involved five complementary elements: reading…

Classic studies of educational media have demonstrated that children can engage in quick, incidental word learning on the basis of a single exposure of a program. Since most words are learned from context, a lingering question has been whether the degree of contextual support affects word learning. Using a within-subjects design this study…

The Hebb repetition paradigm has recently attracted attention as a measure of serial order learning, which underlies word-form learning abilities. Although children are good vocabulary learners, it is surprising that previous Hebb learning studies with young children show rather weak Hebb effects. In this study, we conducted two experiments to…

In a replication study, the researcher investigated the effects of a 4-week vocabulary intervention in which he and a teacher used direct instruction to teach 16 multiple-meaning words to three hard of hearing students in a fifth-grade classroom who read at low levels. The vocabulary intervention was adopted from a study by Alqraini and Paul…

This mixed methods cross-sectional survey study framed in amalgamation theory (Ehri, 2020) and the Simple View of Reading (Gough & Tunmer, 1986) explored the ways in which k-2 general classroom teachers define, understand, and teach sight word development through an orthographic mapping lens. The study utilized a convergent parallel design to…

For elementary learners of Japanese, one of the main difficulties in reading is to distinguish words written in kana. This paper reports on a survey of elementary level learners with two different levels of proficiency to investigate the effectiveness of Japanese graded readers with parts of speech color-coded to distinguish nouns, verbs,…

Typically developing (TD) children, as young as four years of age, have demonstrated enhanced noun learning when orthographic representations are presented during learning tasks. This dissertation investigated the impact of orthographic support on word learning in diverse populations, focusing on children from a variety of clinical categories…

Research investigating incidental vocabulary learning through listening to songs has primarily relied on participants' self-report surveys on listening behaviors and its relationship with their vocabulary knowledge (Kuppens, 2010). Only one experimental study has investigated vocabulary learning gains from listening to songs (Medina, 1993). From…

The purpose of this study was to investigate to what extent bi-modal input improves the word segmentation ability of L2 learners of Japanese. Accurately identifying words in continuous speech is a fundamental process for comprehending the overall message, but studies show that second language (L2) learners often find this task difficult, even when…

In order to inform English foreign language (EFL) diagnostic assessment of literacy, this study examined the extent to which 175 first-language Hebrew-speaking EFL young learners from fifth to tenth grade exhibited differences in single-letter grapheme recognition, sub-word, and word reading, and rapid automatized naming (RAN) of letters and…

The current study investigated the role of visual short-term memory, working memory, and declarative memory as individual differences in the earliest stages of vocabulary and syntactic learning in "Duolingo"-based language instruction. Thirty-eight L1-Greek adults completed memory tasks and engaged in learning Navajo on…
