Texts generated by artificial intelligence agents have been suggested as tools supporting students' learning. The present research analyses the language of texts generated by ChatGPT when solving mathematical problems related to the quadratic equation. We use the functional grammar theoretical framework that includes three meta-functions: the…

This dissertation developed a new learner corpus of Japanese and introduced an error and linguistic annotation scheme specifically designed for Japanese particles. The corpus contains texts written by learners who are in the first year to fourth year university level Japanese courses. The texts in the corpus were tagged with part-of-speech and…

This study aims to demonstrate the need for learner-corpus-informed applications and proposes methods of application that promote the proper use of Korean topic and nominative markers. This study extracted 3004 pieces of error from the error-annotated corpus of the "Korean Learners' Corpus," the largest Korean learner corpus to date. A…

This article examines the use of prompt-based lexical collocations in opinion essays by Vietnamese English as a foreign language (EFL) students. Fifty second-year English majors at a Vietnamese university wrote 100 opinion essays on two topics as progress tests. The AntConc programme (Anthony, 2020) was employed to identify the frequencies of use…

Previous research in English as a Lingua Franca (ELF) has revealed that deviations in lexicogrammar are not always random, but a result of underlying communicative processes (Cogo & Dewey, 2012; Guziurová, 2020; Jafari, 2021; Ranta, 2013, 2022). Most previous studies relied upon spoken interactions, particularly in business and academic…

The present study aimed to catalogue and compare usage patterns of verb-particle constructions (VPCs) in Modern Standard Arabic and English by native and learner writers. Building upon an analysis of a multi-genre monolingual Arabic corpus, use of both Arabic and English VPCs was explored in a bilingual L1 (first language) Arabic L2 (second…

The current study explores error fossilization in the academic writing of Saudi English as a Foreign Language (EFL) undergraduate learners. A manual textual analysis approach, employing corpus content analysis on writing across diverse genres including argumentative, expository, narrative, and descriptive essays was conducted to discover the…

The current study responds to the call for increased dialogue among different areas of additional language research. Specifically, we bring together learner corpus research and variationist approaches to second language acquisition to advance learner corpus research in two ways: (a) by modeling interlanguage development and variability and (b) by…

Although the Japanese reflexive "zibun" can be bound both locally and across clause boundaries, the third-person pronoun "kare" cannot take a local antecedent. These are properties that children need to learn about their language, but we show that the direct evidence of the binding possibilities of "zibun" is sparse…

A compelling body of evidence suggests that EFL students have problem with logical connectors' appropriate use in writing. This study explored Iranian EFL students' adversative connectors use in their essay writing course. To this end, a Learner Corpus of 60393 words consisting of 156 essays was compiled. LOCNESS was chosen as the criterion…

Errors in writing are unavoidable while students are trying to develop their writing skills. There have been several studies on identifying writing problems or errors in students' writing. It is believed that identifying students' written tasks is an effective tool to explore the difficulties involved in learning language. This helps teachers'…

Learning a foreign language for those who have their first and second language often puts learners in imperfection mastery such as irrelevant lexical choice, and source cultural bounds language utterances. Knowing the concepts merely cannot guarantee the process of avoiding mistakes or errors that learners have. There has been an amount of…

Research and pedagogical materials focusing on the acquisition of the determiner/quantifier system in English frequently highlight countability as a locus of difficulty for English language learners, particularly learners whose languages do not overtly mark a count-mass distinction. The current study uses a document analysis approach to analyze…

This paper describes a project developed within an ongoing study at the University of Athens. In our previous studies we analyzed the errors of Greek learners of Italian language, using Learner Corpora evidence and we retrieved useful information about their interlanguage and its interaction to the language learning process. In this study we…
