This study examines the extent to which verb argument construction (VAC) based indices of syntactic complexity could predict four different writing task conditions: a simple task with no repetition (S + NR), a simple task with repetition (S + R), a complex task with no repetition (C + NR), and a complex task with repetition (C + R). Ninety-six…

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…

This study investigates the effects of teacher-focused feedback (TF) and automatic writing evaluation (AWE) on global writing performance as well as syntactic complexity, accuracy, lexical diversity, and fluency (CALF) of English as a foreign language (EFL) learners' narrative and argumentative writings. The participants were randomly assigned 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…

This study investigates how task complexity affects native speakers' and second language (L2) learners', and experts' perceptions of task difficulty in writing tasks. It also explores how task complexity influences English native speakers' and L2 learners' linguistic complexity in their writing. Ninety participants performed one simple and one…

This study seeks to investigate the relationship between text formality and writing quality by quantifying text formality in EFL English writing. In order to conduct the research, 548 English argumentation compositions were evaluated in terms of the five Coh-Metrix text formality dimensions: narrativity, syntactic simplicity, word concreteness,…

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 paper aims to explore topic effect on syntactic complexity in Chinese EFL learners' and English native speakers' writings. To this end, the paper examined 600 argumentative essays on two topics, using 14 measures of syntactic complexity to investigate whether there is significant difference in topic effect on EFL writings and ENS writings.…

Current research on cross-language transfer has focused primarily on literacy development. The present study extends the scope of existing research by focusing on argumentative reasoning, an important but under-research academic skill. A single-case study with a reversal design was conducted with four Chinese-English elementary students with the…

Many empirical findings of previous studies have suggested a connection between motivational factors and L2 writing. Nonetheless, the impact of motivational factors on the genre-based L2 writing has not gained much attention. The present study explored the extent to which the characteristics of two writing tasks involving different genres interact…

This study explores how syntactic complexity and lexical complexity vary in argumentative essays written by L2 learners of English at B2 and C1 CEFR proficiency levels. We approach both syntactic complexity and lexical complexity from a multi-dimensional perspective, examining syntactic complexity at different levels (i.e., global, clausal, and…

In measuring learners' productivity in writing and speaking, there is a formulation known as syntactic and lexical complexity. This study investigates whether there is a difference in syntactic and lexical complexity between L1 and L2 writings or not. This study is quantitative research which employ Web-Based Lexical Complexity Analyser and…

Many studies that have investigated the educational value of online machine translation (MT) in second language (L2) writing generally report significant improvements after MT use, but no study as of yet has comprehensively analyzed the effectiveness of MT use in terms of various measures in syntactic complexity, accuracy, lexical complexity, and…

The present study attempts to identify difficulties that Japanese students encounter with metadiscursive nouns in writing second language (L2) argumentation essays. Metadiscursive nouns are abstract and unspecific nouns which can serve as cohesive markers by retrieving their meanings in the text where they occur. Using a selected number of nouns…
