The measurement of second language (L2) productive lexical proficiency has driven a great deal of research over the past two decades. Research has indicated that more proficient speakers and writers tend to use a wider range of words and that more proficient writers tend to use words that are more sophisticated (less frequent in reference…

This study examines language demands in undergraduate university mathematics classes with a view to better preparing and supporting international and other culturally and linguistically diverse (CLD) students in the United States universities. We observed and analyzed the language demands of 13 entry-level mathematics classes across two large…

This research examined how linguistic differences between African American English (AAE) and Mainstream American English (MAE) impact how children process sentences and learn new information. The central hypothesis of this dissertation is that these linguistic differences adversely impact how AAE-speaking children use contrastive inflectional verb…

The article shines light upon the differences in the vocabulary demands of academic spoken discourse between three broad scientific disciplines: Life Sciences, Physical Sciences, and Social Sciences. By employing the Academic Word List (AWL) and British National Corpus/Corpus of Contemporary American English (BNC/COCA) wordlist, the present study…

In mathematics, the expectation to set up and solve word problems emerges as early as kindergarten; however, many students who experience mathematics difficulty (MD) and dual-language learners often present with specific challenges in this area. To investigate why these populations experience word-problem difficulty, we examined the word, problem…

Interaction has received attention in different fields of applied linguistics. In the field of Second Language Acquisition (SLA), scholars have perceived interaction as a platform where L2 learners can engage in language experimentation. It has been considered in light of Long's (1981) Interaction Hypothesis, which posits that negotiation of…

This study examined the relationships between adult language input and child language production in regard to the quantity and diversity of spoken language, as well as children's knowledge of basic concepts and vocabulary. The quantity and diversity of language provided by teachers and parents were related to children's language output and…

Purpose: This study was designed to assess the utility of a tool for automated analysis of rare vocabulary use in the spoken narratives of a group of school-age children from low-income communities. Method: We evaluated personal and fictional narratives from 76 school-age children from low-income communities (M[subscript age] = 9;3…

The purpose of this historical project was to compare 19th and 20th century books that originated approximately 165 years apart from collections at Miami University (Oxford, OH) in order to interpret how an early language and vocabulary may have emerged from literacy practices of reading printed books to form an early conception of health…

Shared understanding is often achieved in communication interactions at the point in which the participants come to an agreement upon meaning. Without shared meaning, misunderstandings can lead to a breakdown in communication, and possibly failure on collaborative tasks. The purpose of the present study was to examine how students, preservice, and…

It has long been recognized that collocations, or chunks of formulaic language, are essential and frequent in language (Henriksen, 2012; Sinclair, 2004). Therefore they are a crucial part of Second Language Acquisition (SLA). Linguistic scholars Pawley y Syder (1983: 192) remark that "in order to know a language, the [second language] (L2)…

With regard to parents making communication approach decisions for their children with hearing loss, Crowe et al. (2014) suggested that key themes were: feasibility; sources of information; child characteristics; and, future opportunities. For children using cochlear implants (CI/s), the present study aimed to understand parental preferences…

This exploratory multiple case study investigated how preschool-age, Spanish-English emergent bilingual (EB) children with diverse language profiles leverage their discursive resources to engage with peers and teachers in sociodramatic play (SDP) interactions. Data were collected over the course of one academic year, including weekly video…

Teachers need to develop a variety of pedagogical strategies that can encourage precise and accurate communication--an extremely important 21st century skill. Precision with STEM oral language is essential. Emphasizing oral communication with precise language in combination with increased spatial skills with modeling can improve the chances of…
