Children learn words in a social environment. In my dissertation, I examine how caregivers' social cues facilitate young children's word learning in settings that mirror their typical, dynamic learning environments. In Chapter 1, I overview prior work examining how social cues may support word learning, focusing on possible mechanisms underlying…

A growing body of literature on the pedagogical effectiveness of clickers in a second language (L2) context has revealed that clickers can promote learning. However, the extent to which clickers play a role in L2 acquisition compared to other pedagogical approaches lacks consensus; in addition, most research has focused on adult learners and has…

English learners (ELs) struggle with vocabulary learning and often evidence serious vocabulary gaps. It is challenging, especially for professionals who do not speak the native language of the students, to teach EL students vocabulary that supports academic learning, is compatible with classroom instruction, and considers their changing language…

Young children can exploit the syntactic context of a novel word to narrow down its probable meaning. But how do they learn which contexts are linked to which semantic features in the first place? We investigate if 3- to 4-year-old children (n = 60) can learn about a syntactic context from tracking its use with only a few familiar words. After…

Word learning is typically studied as a problem in which children need to learn a single meaning for a new word. And by most theories, children's learning is itself guided by the assumption that a new word will have only one meaning. However, the majority of words in languages are polysemous, carrying multiple related and distinct meanings. Here,…

This study aimed at investigating the impacts of a Task-Based Extensive Reading (TBER) program on the reading abilities of Thai high school students at a demonstration school in Thailand. Nine Mattayomsuksa 6 students from a Math-English program, selected through purposive sampling, participated in this TBER program. In this program, each student…

Extensive reading (ER) has been found to have an assortment of positive effects on various aspects of second/foreign language learning. However, few studies have investigated its impacts on learners of Chinese as a Foreign Language (CFL), especially early beginning learners. To address this gap, this study reports an intervention of extensive…

Motivated by the increasing popularity of service-provider virtual exchanges (SPVEs), in which native speakers (NS) are trained, supervised, and paid by a third-party company to converse about cultural topics with second language (L2) learners, this study examines the potential of L2-NS videoconferencing conversations to foster negotiation of…

Purpose: This study examines undergraduates' perceptions of the effectiveness of two metacognitive monitoring strategies, active comprehension monitoring (ACM) and audible elaborative rehearsal (AER), for gaining specialized vocabulary and concept (SVC) knowledge in communication sciences and disorders. Method: The participants were 64…

A wide variety of language skills has been shown to be compromised in children from low socioeconomic status (SES). However, few studies have investigated the effect of SES on language development in infants. The aim of this study is two-fold: to investigate when the first SES-effects on language can be observed and to explore the effects of three…

Background/purpose: This study examines how well EFL students perform in English language learning using Kagan's Cooperative Learning Approach (KCLA). Conventional teaching approaches frequently fail to actively involve students, which lowers achievement. With an emphasis on teamwork and active engagement, this study seeks to ascertain whether…

This study aimed to utilise artificial intelligence (AI) tools to create animations to assess the impact of AI-created cartoons on vocabulary growth and motivation levels among learners. For this purpose, 80 Omani EFL learners with a pre-intermediate level of English proficiency were randomly assigned to an experimental and a control group, each…

This systematic review analyzed the relationship between emergent writing, alphabet knowledge and vocabulary and children's words/pseudowords reading and writing performances in Portuguese literacy acquisition. A systematic search was conducted in the PsycInfo and BVS databases (2000-2024). After the selection process, 11 studies were included in…

Background: Previous studies have explored the size and word type composition (nouns, predicates, etc.) of expressive vocabularies of preschool children with Down syndrome, both spoken and signed. Separately, overall preferences for modality of expression have also been explored. Aims: To extend previous findings by describing the relationships…

Understanding the factors associated with variation in the implementation of educational programs has emerged as a key research focus, in an effort to identify how promising programs can be scaled up across their targeted contexts. The current study explored demographic-related variation in program dosage using a novel source of implementation…
