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 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 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…

Researchers have been investigating the effects of different planning conditions on learners' second language (L2) writing performance. However, whether such effects differ regarding specific planning conditions and task complexity has remained underexplored. This study examined the effects of pre-task planning (PTP) versus unpressured online…

This study investigated if the difficulty of instructional classroom English in primary teacher-guidebooks of English is adequately manipulated by learner-proficiency. Corpora of classroom English were compiled from 20 guidebooks from five publishers, approved following the 2015 Revised National Curriculum of Korea. Extracted materials from grades…

The reader's ability to connect new information to existing knowledge is crucial when reading a text. Nonetheless, text complexity, in many ways, is more linguistic than cognitive. It encompasses the degree of sophistication, and how challenging a reading section is. Depending on the section, such difficulty may appear on the vocabulary level, in…

The purpose of this study was to investigate the continuity of reading passages of Korean high school English textbooks with the 2015 Revised National Curriculum using CohMetrix, a software that analyzes English texts in a range of linguistic features. Twentyone English textbooks were analyzed: 11 High School English, five High School English I,…

From the perspective of complexity theory and based on Robinson's Cognition Hypothesis and the Triadic Componential Framework, this paper investigated the effect of manipulating task complexity along resource-dispersing dimension on L2 written performance. The results showed that: 1) Significant interactive effects were found between the two…

This paper attempts to investigate the repetition of Relative Clauses (RCs) in Mandarin children with Developmental Language Disorder (DLD) (aged 4; 5 to 6; 0) and their typically developing (TD) peers. The results of a sentence repetition task indicate that Mandarin children with DLD perform significantly worse than both groups of TD children,…

Achieving sufficient proficiency in academic writing is critical in university level setting. It is not surprising hence, that the admission to English speaking universities is usually conditioned not only by a particular total score from Standardized tests of English proficiency, e.g., TOEFL or IELTs but also a specific band score in writing. To…

Assessment is a useful process as it provides various stakeholders (e.g., teachers, parents, government, employers) with information about students' competence in a particular subject area. However, for the information generated by assessment to be useful, it needs to support valid inferences. One factor that can undermine the validity of…

We explored whether task complexity, operationalized by the two types of writing prompts, affects EFL high school students' narrative writing in terms of syntactic complexity, lexical complexity, fluency, cohesion, and text quality. 32 intermediate EFL students who were randomly assigned to two prompt groups completed a written narrative task…

This study examined the development of text complexity for the past 25 years of reading comprehension passages in the National Matriculation English Test (NMET) in China. Text complexity of 206 reading passages at lexical, syntactic, and discourse levels has been measured longitudinally and compared across the years. The natural language…

In this pilot study, we examine the suitability of materials for a vocabulary intervention designed to influence the amount of complex syntax teachers use in at-risk preschool classrooms. Six Head Start classrooms were assigned to one of two vocabulary interventions: a condition using cognitive verbs, which are biased toward complex syntax (e.g.…

Difficulties in mathematics learning are a multi-faceted issue and the role of language in it is crucial. Language of mathematics includes mathematics text, discourse in classroom and language used in evaluation situations with its specific verbal, symbolic expressions, structure and function. Ambiguity arising from the difference between formal…
