This study modeled the effects of essay length and language features on the rated quality of second language (L2) expository and argumentative essays composed by Chinese university students. Latent variables were writing quality captured by essay scores, and lexical sophistication, syntactic complexity and cohesion, each of which was measured by…

The use of subordination enables language users to achieve syntactic efficiency by allowing them to connect ideas in temporal/logical relation. Although the importance of subordination has been recognized in previous research on second language (L2) writing, it has been typically assessed with global indices that measure overall ratio of…

This corpus-based multifactorial study delves deeper into the well-known alternation between bare and full infinitive complements, specifically regarding the "help" concordances. It extends the line of research to learners' language productions with a focus on comparing and contrasting the probabilistic grammatical knowledge reflected in…

Unfolding models are frequently used to develop scales for measuring attitudes. Recently, unfolding models have been applied to examine rater severity and accuracy within the context of rater-mediated assessments. One of the problems in applying unfolding models to rater-mediated assessments is that the substantive interpretations of the latent…

The present study investigated the potential of writing in English as a foreign language (EFL) for language learning by manipulating cognitive task complexity based on related models and hypotheses. English essays written by 59 Chinese postgraduate EFL students from different subject areas were analysed with reference to writing complexity,…

This study aimed to analyze common syntactic errors found in the argumentative essays of third-year English major students at the Faculty of Foreign Languages, Van Lang University, Vietnam. Quantitative and qualitative methods were used to obtain data in this study. The quantitative approach involved counting and calculating the frequency,…

This study explores syntactic and lexical complexity in argumentative essays written by Artificial Intelligence (AI) and Humans (HS). First year Tswana second language (L2) learners of English in a South African University wrote the HS argumentative essays. The AI essays have been generated by ChatGPT-3.5 on the same topics. Using a…

Broadly defined, academic language (AL) is a set of lexical-grammatical norms and registers commonly used in educational and academic discourse. Mastery of academic language in writing is an important aspect of writing instruction and assessment. The purpose of this study was to use Natural Language Processing (NLP) tools to examine the extent to…

This study explored the relationship between task complexity, textual emotionality, and linguistic complexity in second language (L2) writing. Fifty-eight L2 English learners performed simple and complex versions of an argumentative writing task manipulated along with resource-­directing variables. The essays were first analysed for textual…

Over the past two decades, reflective writing has occupied an increasingly prominent position in composition theory, pedagogy, and assessment as researchers have described the value of reflection and reflective writing in college students' development of higher-order writing skills, such as genre conventions (Yancey, "Reflection";…

This research aims to investigate the effects of two teaching sequences -- interleaving and blocking -- on the participants' use of three types of cohesive devices (conjunctions, conjunctive adverbs and prepositions [thereafter CCPs]) in their argumentative essays. The participants included 50 native Cantonese-speaking university students taking…

This article reports on a comparative analysis of two sets of essays, student-discursive essays (SDEs) and ChatGPT-generated discursive essays (ChatGPT-GDEs) on the same essay topic using Coh-Metrix. It focused on three Coh-Metrix indices, lexical density, syntactic complexity, and referential cohesion as the basis for the comparative analysis.…

This study examined the extent of perspective taking and language features represented in secondary students' text-based analytical writing. We investigated: (1) whether perspective taking is related to writing quality, accounting for language features in writing; (2) whether students' English learner status is related to perspectives represented…

Students' writing proficiency is measured through holistic and analytical ratings in writing assessment; however, recent studies suggest that measurement of syntactic complexity in second language writing research has become an effective measure of writing proficiency. Within this paradigm, we investigated how automated measurement of syntactic…

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…
