Dual language learners are a growing population in early learning and care settings. Young DLLs have the potential to develop proficiency in two languages when provided adequate supports; however, most teachers of young DLLs feel inadequately prepared to support DLLs. Cultivating Oral Language and Literacy Talent in Students (COLLTS) is an…

Providing opportunities for students to express ideas in their own words is key to promoting authentic disciplinary engagement and robust conceptual understanding. In this article, we discuss our experiences and observations related to students' informal vocabulary in the context of a middle school probability unit. We noticed that students'…

Children's early vocabulary shows sex differences -- with boys having smaller vocabularies than age-comparable girls -- a pattern that becomes evident in both singletons and twins. Twins also use fewer words than their singleton peers. However, we know relatively less about sex differences in early gesturing in singletons or twins, and also how…

The present study involved the analysis of 81 second language instructed vocabulary acquisition (L2 IVA) studies over 2 phases. In Phase I, we categorized and coded the effect sizes of the studies. Observing that the basic between- and within-subject design dichotomy lacked the sensitivity to capture the heterogeneity of observed effects, we…

Toddlers vary widely in the rate at which they develop vocabulary. This variation predicts later language development and school success at the group level; however, we cannot determine which children with slower vocabulary development in the second year will continue to have difficulty. In this article, I argue that this is because we lack…

Learning about emotions is an important part of children's social and communicative development. How does children's emotion-related vocabulary emerge over development? How may emotion-related information in caregiver input support learning of emotion labels and other emotion-related words? This investigation examined language production and input…

Children's ability to recognize object shape is foundational for successful early word learning. However, the prototypical shape of objects may not be easily accessible--take margarita glasses, for instance. The current study examined 304 U.S. children 17- to 42-month-old (152 females) from 2017 to 2020, asking how shape, age, and vocabulary…

Purpose: The first purpose of this study was to investigate how children's knowledge of taught words and transfer words assessed 10 months after a morphological vocabulary intervention can be predicted by means of language measures taken before the intervention. The second purpose was to investigate whether and how immediate post-intervention…

Vocabulary plays a significant role in the learning process of English as a Foreign Language (EFL) students, especially undergraduates who need to read academic materials and listen to specialized lectures in English. However, retaining lexical items is still a challenging task for many EFL learners. The current study seeks to examine the…

Evidence indicates that well-planned vocabulary interventions can be highly effective in helping students with language-based learning disabilities to develop the necessary vocabulary skills for literacy success. Although many researchers recognize the general importance of attending to psychological factors such as student motivation in…

Kindergarten students commonly receive a limited amount of exposure to scientific concepts and informational texts. The present study used a multiple probe design across participants to determine the effects of shared reading instruction on three kindergarten students' science-related vocabulary acquisition in a virtual classroom during the…

Purpose: This feasibility study examined a caregiver-implemented telehealth model of the Vocabulary Acquisition and Usage for Late Talkers (VAULT) protocol. We asked whether caregivers could reach fidelity on VAULT, if the protocol was socially and ecologically valid, and if late-talking toddlers could learn new words with this model. Method: Five…

Vocabulary experts recommend first language (L1) translation equivalents for establishing form-meaning mappings for new second language (L2) words, especially for lower proficiency learners. Empirical evidence to date speaks in favor of L1 translation equivalents over L2 meaning definitions, but most studies have investigated bi- rather than…

In order to meet the communication needs of individuals who use Augmentative and Alternative Communication (AAC) devices, communication partners are often responsible for the programming of the AAC devices. However, the prolonged learning time and operational demands of AAC devices are often barriers to an efficient use of time during a therapy…

Vocabulary knowledge has been recognized as a crucial component in learning and teaching of both native and non-native learners, text understanding, and educational success (Coxhead, 2018; Saeedi et al., 2023; Schmitt et al., 2021), leading to the development of word lists for different purposes. Hence, this study aimed at developing a newspaper…
