EL1 learners' receptive morphological words (root, inflected, and derived words) develop on different scales, but whether they develop similarly in EFL learners' language production is still unknown and deserves an examination. The answer may provide a clue to theoretical controversy about whether language learners' morphologically defined words…

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…

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 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…

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…

The current article studies the competencies of plurilingual students and how these competencies are exploited in the learning of French as a Foreign Language. Adopting a translanguaging theoretical approach, we argue that learners of foreign languages who already speak at least one other language have some linguistic competencies which manifest…

The present study employs regulatory focus theory (Higgins, 1997) to investigate the effects of L2 speakers' chronic regulatory focus on their L2 pragmatic versus grammatical awareness. It involved the participation of 121 Chinese students, who are English language learners, at a university in the United States. Haws et al.'s (2010) questionnaire…

Over the last decades, applied linguistics and language teaching/learning have investigated language errors committed by learners for both diagnostic and prognostic purposes. Initially, error analysis was conducted manually and involved a limited number of corpus. However, computer software advancement has facilitated much larger amounts of data…

This study analyzed semantic errors in the written compositions of first-year BSEd English students. 86 participants were asked to write a narrative essay and provide feedback on their writing difficulties and language learning needs. The collected data were statistically analyzed. Semantic errors were categorized into 8 types: code-switching,…

While acquiring a second language, learners may encounter challenges and difficulties in effectively carrying out verbal communication in the second language. Mastering the apology speech act is a challenge for L2 learners. The objective of this study is to identify the apology strategies utilized by individuals learning the Japanese language, as…

Translation of scientific texts has been regarded as having the least freedom and variety in rendition; however, inconsistencies occur when translators work with two language systems that differ in reference to time, such as between Chinese and English. Tense is one of the core components of English grammar, but such information is not apparent in…

Dative alternation between prepositional and double object datives has been a popular topic in second language (L2) acquisition, but only few studies deal with discourse constraints such as the "given-before-new" principle, or given-new (GN) ordering, which describes the tendency to place given information before new information. The…

Research on the acquisition order of inflectional morphemes in English has shown that third-person singular "-s" (3SG"-s") is challenging to acquire and acquired later than "be" copula by both L1 and L2 learners of English. In a departure from the usual practice of controlled elicitation, the current study…

This longitudinal case study investigated the developmental trajectories of two participants enrolled in an ITA oral communication course at Purdue University. The course provides language support to the ITA population who play a crucial role in higher education programs in the U.S. (Gorsuch, 2016). Over four months (i.e., one semester), I…
