Sociolinguistic variation (SLV) entails that language is affected by social context (i.e. register, pragmatics). Interest in the acquisition of sociolinguistic variation in a second language (L2-SLV), as a key component of communicative competence, has grown exponentially over the past thirty years (Geeslin & Long, 2014). Researchers have…

Children's early understanding of mathematics provides a foundation for later success in school. Identifying ways to enhance mathematical instruction is crucial to understanding the ideal ways to promote academic success. Previous work has identified mathematical language (i.e., the words and concepts related to early mathematical development such…

The number of U.S. children living in households with extended families has greatly increased in the last 4 decades. This demographic shift calls for a reevaluation of the impact of household size on children's development. Household density (HHD), measured as the ratio of people to bedrooms in a home, has been shown to negatively relate to…

Ignoring technology in teaching English language in EFL contexts persuaded the researchers to do this study. In fact, this research looked at how Saudi Arabian EFL learners' academic achievement (AA), creativity, and academic buoyancy (AB) were affected by vocabulary acquisition with and without the use of technology. Fifty intermediate EFL…

Multimedia glosses have been examined extensively by researchers for over three decades to determine their possible effects in second language (L2) vocabulary acquisition. Many meta-analytic studies aimed to determine the extent to which glosses can impact L2 vocabulary learning and the moderators that can mediate the results of meta-analytic…

In word learning, learners need to identify the referent of words by leveraging the fact that the same word may co-occur with different sets of objects. This raises the question, what do children remember from "in the moment" that they can use for cross-situational learning? Furthermore, do children represent pictures of familiar animals…

Word learning depends on attention -- children must focus on the right things at the right times. However, autistic children often display restricted interests, limiting their intake of stimuli during word learning. This study investigates how category interests influence word learning in autism and neurotypical development. Autistic and…

Despite the well-established role of lexis in proficiency in the four skills, a great deal of research has focused on the importance of vocabulary breadth and depth in reading. Therefore, the neglect of productive skills has motivated recent calls to inspect the impact of lexical dimensions on writing ability. Using Partial Least Squares…

Learning vocabulary is a central and time-consuming endeavour for a language learner and it has thus been suggested that the foreign language classroom has to supply explicit support for students' vocabulary development. A major source of explicit word focus is vocabulary exercises in teaching materials and students' learning can be facilitated if…

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…
