Clickers are hand-held devices that wirelessly transmit student input to a computer: students answer multiple-choice questions using their clickers and the answer distribution is displayed on a screen. Previous studies suggest that the pedagogical use of these devices may contribute to learning and that they are positively perceived by students in…

This study aimed to adapt and validate the Word Complexity Measure (WCM) for Persian-speaking toddlers. The WCM is a tool for assessing phonological complexity, originally proposed by Stoel-Gammon. The study was conducted in two phases: (1) adapting the WCM parameters to the Persian language and (2) conducting a validation study with 60…

This corpus-based study investigates the similarities and differences among the three synonymous adjectives: "careful," "cautious," and "wary" in terms of genre distribution, collocational patterns, semantic preference, and semantic prosody. Data were drawn from the Corpus of Contemporary American English (COCA). The…

Math and language are inextricably connected. Math cannot be taught without naming certain concepts and finding ways to express mathematical ideas. With the increasing demands on teachers to meet the needs of diverse learners, the role of language development in the mathematics classroom must be at the forefront of instruction. Identifying and…

The goal of the current research was to determine if conceptual metaphors are activated when people read idioms within a text. Participants read passages that included idioms that were consistent ("blow your top") or inconsistent ("bite his head off") with an underlying conceptual metaphor (ANGER IS HEATED FLUID IN A CONTAINER)…

One way children are remarkable learners is that they learn from others. Critically, children are selective when assessing from whom to learn, particularly in the domain of word learning. We conducted an analysis of children's selective word learning, reviewing 63 papers on 6,525 participants. Children's ability to engage in selective word…

Competing theories are quite common in education. In spelling research, two general perspectives have emerged over the years: stage theory and repertoire/alternative theories. Exploring these perspectives is important because teachers need to understand how spelling knowledge is critical for learning to read words and to write them. Stage theory…

This study examined how inferences about epistemic competence and generalized labeling errors influence children's selective word learning. Three- to 4-year-olds (N = 128) learned words from informants who asked questions about objects, mentioning either correct or incorrect labels. Such questions do not convey stark differences in informants'…

We examined full-term and preterm infants' perception of frequent and infrequent phonotactic pairings involving sibilants and liquids. Infants were tested on their preference for syllables with onsets involving /s/ or /?/ followed by /l/ or /r/ using the Headturn Preference Procedure. Full-term infants preferred the frequent to the infrequent…

In today's increasingly linguistically diverse classrooms, all science teachers require expertise in supporting students' language development simultaneous to content-based classroom instruction. Current science-oriented K-12 teaching frameworks and standards promote a vision of learning and doing science that entails engaging students in…

It is widely accepted that associative recognition can be supported by familiarity through integrating more than two stimuli into a unit, but there are still three unsolved questions: (1) how unitization affects recollection-based associative recognition; (2) whether it is necessary to match the level of unitization (LOU) between original and…

A group of words, labeled the core vocabulary, can be expected to be prominent across all texts. Scholarship made possible by digital databases of words and new analytic systems has shown that approximately 2,500 morphological families account for most of the words in texts--an average of 91.5% of all words in the Common Core State Standards…

This study investigated the relation between Dual Language Learners' (N = 90) vocabulary and grammar comprehension and word learning processes in preschool (aged 3-through-5 years). Of interest was whether: (a) performance in Spanish correlated with performance in English within each domain; and (b) comprehension predicted novel word learning…

Background: Vocabulary development is closely associated with morphological knowledge, yet work is needed to understand the mechanisms underpinning this relationship. One possibility is that because morphological relationships entail systematic mappings between word form (phonology and orthography) and word meaning (semantics and grammar),…

Purpose: Word learning difficulties have been documented in multiple studies involving children with dyslexia and developmental language disorder (DLD; see also specific language impairment). However, no previous studies have directly contrasted word learning in these two frequently co-occurring disorders. We examined word learning in second-grade…
