Although lexical diversity is often used as a measure of productive proficiency (e.g., as an aspect of lexical complexity) in SLA studies involving oral tasks, relatively little research has been conducted to support the reliability and/or validity of these indices in spoken contexts. Furthermore, SLA researchers commonly use indices of lexical…

A child's ability to understand text (reading comprehension) can greatly impact both their ability to learn in the classroom and their future contributions to society. Reading comprehension draws on oral language; behavioural measures of knowledge at the word and sentence levels have been shown to be related to children's reading comprehension. In…

In this article we identify ways to scaffold content-specific instruction to support your multilingual learners' academic language development. With the definition that academic language compromises of vocabulary, linguistic functions, and syntax, we share ways to integrate three instructional practices across your instruction. These practices…

This study proposed an innovative automated approach to differentiation of the vocabulary proficiency of Chinese speakers. A robust K-means algorithm was designed to compare the oral proficiency between L1 and L2 Chinese speakers regarding lexical richness and how relatively effective the various lexical measures were in performing the…

In this article, we report the results of a study undertaken at the University of Cyprus (2017-2020) in the framework of the research project MapCyArS financed by the Leventis Foundation. The study concerns the design and development of an assessment test to evaluate proficiency in Cypriot Arabic (CA), a severely endangered language spoken in…

There is resounding evidence of the existence of direct precursors of written language, most specifically phonological awareness, letter knowledge, vocabulary, and oral comprehension. The initial differences identified in the development of written language precursors are directly related to subsequent students' academic trajectories.…

Technology-based remote research methods are increasingly widespread, including learning assessments in child development and education research. However, little is known about whether technology-based remote assessments remain as valid and reliable as in-person assessments. We developed a low-cost phone-based language and literacy assessment for…

This longitudinal case study investigated the developmental trajectories of two participants enrolled in an ITA oral communication course at Purdue University. The course provides language support to the ITA population who play a crucial role in higher education programs in the U.S. (Gorsuch, 2016). Over four months (i.e., one semester), I…

We conducted a meta-analysis to investigate reading-writing relations. Beyond the overall relation, we systematically investigated moderation of the relation as a function of linguistic grain size (word reading and spelling versus reading comprehension and written composition), measurement of reading comprehension (e.g., multiple choice,…

Background: It is widely acknowledged that children with developmental language disorder (DLD) predominantly have difficulties in the areas of grammar and vocabulary, with preserved pragmatic skills. Consequently, few studies focus on the pragmatic skills of children with DLD, and there is a distinct lack of studies examining the effectiveness of…

The rating of proficiency tests that use the Inter-agency Roundtable (ILR) and American Council on the Teaching of Foreign Languages (ACTFL) guidelines claims that each major level is based on hierarchal linguistic functions that require mastery of multidimensional traits in such a way that each level subsumes the levels beneath it. These…

Efforts to improve classroom language practices and children's language learning, as a means of supporting reading comprehension, may depend on teachers' knowledge about language structures and language development. To date, however, educational researchers and teacher educators have little understanding about teachers' knowledge about oral…

The current study examined the extent to which cognitive fluency (CF) contributes to utterance fluency (UF) at the level of constructs. A total of 128 Japanese-speaking learners of English completed four speaking tasks--argumentative task, picture narrative task, reading-to-speaking task, and reading-while-listening-to-speaking task--and a battery…

We conducted a meta-analysis to investigate reading-writing relations. Beyond the overall relation, we systematically investigated moderation of the relation as a function of linguistic grain size (word reading and spelling versus reading comprehension and written composition), measurement of reading comprehension (e.g., multiple choice,…

The present study investigates the effect of task repetition and individual differences on Vietnamese English as a foreign language (EFL) learners' lexical use and fluency in oral task performance. The study adopts a within-subjects design with forty students performing the same narrative task twice. Students also completed two prior vocabulary…
