Lexical diversity (LD) is an important indicator of second language lexical development. Much research has investigated LD indices, with a focus on learners of English. However, further research is needed in languages that are typologically distinct from English, such as Korean. In this study, we evaluated the reliability and validity of LD…

Enhancing proficiency in argumentative writing in English has always been a challenge for English as a Foreign Language (EFL) learners. Despite the widespread use of argumentative essays in international tests such as International English Language Testing System (IELTS) and Tests of English as a Foreign Language (TOEFL) in recent years, the…

This study investigates the extent to which (a) Spanish heritage (HL) and second language (L2) writers' linguistic complexity differs across register contexts and (b) Spanish proficiency and writing motivational beliefs differentially affect HL and L2 writers' performance. Participants were 58 HL and 54 L2 Spanish learners who completed two…

Argumentation is a complex skill essential for English as a Foreign Language (EFL) students to effectively use their English language and reasoning abilities in writing and speaking. Constructing arguments without proper collaborative scaffolding and technological support can be cognitively demanding. Generative artificial intelligence (Gen AI) in…

Designed to gauge the actions, skills, and strategies that students use to identify, extract, and synthesize information from multiple source materials, integrated writing tasks are particularly challenging for ESL writers. Previous research tended to focus on a limited number of integrated tasks, mostly summaries of one or two sources, thus…

This is a qualitative case study framed by a sociosemiotic theoretical framework to explore science and language instruction with three Emergent Bilinguals (EBs) in sixth grade. The study details the modeling and explanatory processes used by EBs to mediate science learning through evidence-based argumentation. A thematic analysis of students'…

This study investigates the relationship between socioeconomic status (SES), self-regulated learning strategies (SRLSs), and writing proficiency of complexity, accuracy, and fluency (CAF) in English as a second language writing learning context, using Bourdieu's theory of social practice as a framework. This study's conceptual model specifies that…

The goal of this project was to design a scaffolded learning activity that develops English learners' (ELs) argumentation skills. In this study, we investigated how middle school ELs interacted with a game-enhanced scenario-based assessment of argumentation skills (named "Seaball"). The target skills included identifying and classifying…

It is widely recognized that writing conferences benefit second or foreign language writers for the immediacy and the potential to address their needs and provide tailored and individualized support. However, limited attention has been given to the foci and interaction between teacher and student in writing conferences longitudinally. To address…

Language and argument are epistemic tools that learners can use to help them generate and validate knowledge for themselves, as emphasized in NGSS and previous NRC reports. Not all learning environments elicit or support the use of these epistemic tools equally, thus affecting how students grow in competence in relation to their use. The present…

This article provides three major contributions to the literature: we provide granular information on the development of student argumentative writing across secondary school; we replicate the MacArthur et al. model of Natural Language Processing (NLP) writing features that predict quality with a younger group of students; and we are able to…

While it is common for deaf children to be bilingual in a spoken and signed language, studies often attribute any delays in language acquisition to language deprivation, rather than as a result of cross-linguistic interaction. This study compares the production of simple sentences in three languages (Palestinian Arabic, Modern Standard Arabic, and…

Making decisions, reasoning, and constructing arguments with scientific evidence are essential skills for all members of society, especially in a world facing complex socioscientific issues such as climate change and pandemics. Argumentation is a complex linguistic practice but little is known about how students from diverse language backgrounds…

Enabling learners to successfully use their second language (L2) in meaningful ways is a critical goal of instruction. Ultimately, most learners want to meet the L2 demands of the contexts in which they will use the language. To accomplish this, learners must develop linguistic knowledge and apply it in a manner that is contextually appropriate…

The use of interactional metadiscourse markers in opinion paragraphs written by A2-level English learners was investigated in this research. Although metadiscourse is commonly studied in discourse analysis, pragmatics, and language teaching, there has been limited attention given to the writing of beginner-level language learners. Metadiscourse is…
