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 assessed the effect of adjectives and noun premodifiers on L2 noun phrase comprehension and error types among English Language Learners. We also examined the correlation between L2 noun phrase comprehension and L2 reading comprehension, as well as the contribution of L2 noun phrase comprehension to L2 reading comprehension. One hundred…

In the past two decades, corpora have been proposed as valuable computer-assisted tools for teaching and learning academic writing in English at the university level. This article reports on an empirical study that sought to examine the effectiveness of direct corpus consultation in overcoming vocabulary errors in academic writing. This study is…

Heritage speakers (HS) have been shown to experience difficulties with inflectional morphology (particularly with irregular morphology) and to frequently overapply regular morphology. The present study seeks to get further insight into the inflectional processes of HS by investigating how these are generalized to nonce words in language…

Second-language learners of American Sign Language (ASL) often struggle in the acquisition of more complex ASL aspects, such as role shift, constructed action, and eye gaze to represent characters and their actions with narratives. These learners also often overestimate their ASL skill level. This study investigated errors in second modality,…

Despite the growth of research on mobile technologies in educational contexts, research on language teachers' perceptions of mobile technologies -- particularly in the English as a Foreign Language (EFL) -- remains sparse. Hence, the present study explored EFL teachers' perceptions of using Google keyboard (Gboard) for L2 writing instruction. The…

Automatic speech recognition (ASR) has considerable potential to model aspects of classroom discourse with the goals of automated assessment, feedback, and instructional support. However, modeling student talk is besieged by numerous challenges including a lack of data for child speech, low signal to noise ratio, speech disfluencies, and…

This article proposes a novel account for the overuse of free morphemes and underuse of bound morphemes in English as a second language (L2) based on the framework of Distributed Morphology. It will be argued that an Economy Principle 'Do everything in Narrow Syntax (DENS)' operates in the L2 learner's computational system. Consequently,…

Despite the significant impact of the lexical approach for vocabulary learning, its classroom implementation has not been uniform. While related activities share the common Observe-Hypothesize-Experiment (OHE) elements, practitioners and researchers do not highlight how language input from the observing stage is turned into output and at what…

In this article, we present an analysis of the complexity of grammatical constraints and their impact on early language acquisition of inflectional morphemes in Malayalam. We use the natural speech production data of two monolingual children acquiring Malayalam between the ages 1;9-2;10 and 2;3-3;0 and three bilingual children acquiring…

This study investigated three key issues in heritage language (HL) research. Previous research shows HL speakers have an advantage on oral production tasks compared to L2 speakers who instead perform better on written tasks. Furthermore, both L2 and HL speakers are claimed to have a "yes-bias" towards retaining ungrammaticality in GJTs.…

This article offers a proposal for integrating the social network Facebook into an English as a Foreign Language (EFL) classroom in tertiary education. The main objectives of this article are the following: (1) to offer a pedagogical proposal so that students can develop written skills and grammar at the same time that they acquire social…

We used the elicited production task to explore the production of short and long passives in 15 Mandarin-speaking preschool children with Developmental Language Disorder (DLD; aged 4;2-5;11) in comparison with 15 Typically Developing Aged-matched (TDA) children (aged 4;3-5;8) and 15 Typically Developing Younger (TDY) children (aged 3;2-4;3). This…

This corpus-based study investigates lexical richness in English writing by Chinese senior high school students. Lexical uses in 303 compositions were compared across three grades in terms of lexical sophistication, variation, density and errors. Timed compositions were sampled from Writing Corpus of English Learners, and the sample sizes of three…

Writing is often considered the most difficult language skill for EFL learners due to its persistent grammatical and lexical challenges. Although tools such as Google Translate and ChatGPT are increasingly used, concerns persist regarding overreliance and reduced learner autonomy. This study investigated the grammatical errors and writing…
