Evidence from usage-based studies of second language (L2) acquisition reveals that a main source of L2 learners' developing grammars is the L2 input to which learners are regularly exposed. What learners develop from their extended engagement in the sequences of actions comprising the input is not an acontextual system of grammatical units but…

An extensive number of corrective feedback (CF) studies have examined learners' errors with grammar, vocabulary, pronunciation, and spelling (non-formulaic forms) and established an association between learners' uptake of CF and their second language development. However, learners' errors with formulaic sequences (FSs) comprising idioms,…

Lexical ability, an umbrella term to cover various knowledge and skills pertaining to words in print, is a key component in reading comprehension. Little is known how different facets of lexical ability jointly contribute to L2 reading comprehension and how the contributions may differ between higher- and lower-proficiency L2 learners. This study,…

Developing L2 learners' productive mastery of vocabulary is a challenging task. Recent research has called for greater attention to understanding how receptive vocabulary may be transformed for productive use (Schmitt, 2019). Using a design-based research methodology, this study investigated adult ESL learners' productive oral vocabulary…

This study investigates the acquisition of genericity in L2 French and L3 English. While some exponents become generic by assembling morphological, syntactic and discursive cues, definite singular nominals additionally require the well-established kind restriction. It is a pragmatic and language-specific constraint. The participants are L1 Arabic…

The present study systematically reviewed research that was conducted to analyze the errors within the written expressions of individuals learning Turkish as a foreign language. The sample of the study consisted of 16 articles that were identified through the review of literature. The articles that focused on the written expression errors made by…

Target language instruction in multilingual settings cannot ignore the linguistic diversity of both the learners and the society. Rather than ignoring the individual and societal multilingualism, leveraging them as resources in learning the target language can be beneficial. Developing such multilingual instruction is an organic, iterative process…

The aim of the study was to identify the factors that contribute to speaking anxiety in Thai adult EFL learners working in an online media company and enrolled in an English course provided by the company, as well as to discover the anxiety reduction techniques used by these learners. The results showed that significant contributors to speaking…

Inflectional affixes expressing the same grammatical category (e.g., subject agreement) tend to appear in the same morphological position in the word. We hypothesize that this cross-linguistic tendency toward "category clustering" is at least partly the result of a learning bias, which facilitates the transmission of morphology from one…

The current study explores whether form-focused instruction with different timing and availability conditions can be used with repetitive writing tasks to enhance grammatical accuracy and fluency. Sixty-one intermediate English as a foreign language (EFL) learners performed three text reconstruction tasks: Task 1, Repeat Task, New Task, and…

An extensive number of studies have examined the effectiveness of incidental focus on form (FonF) measured through uptake in primarily communicative activities and established an association between learners' uptake of linguistic features and their subsequent second language development. In this strand of research, the analysis of linguistic forms…

This dissertation examines the extent to which lexical aspect and grounding influence the acquisition of tense and aspect by ninety-four instructed adult learners of Italian in two academic settings in North America. The semantic notions of tense and aspect have been extensively investigated in the domain of second language acquisition. After more…

Multilingual instruction takes many shapes and forms depending on the affordances and limitations of the context in which it is implemented. Because multilingual instruction is often context-specific, it has to be designed in collaboration with local stakeholders and developed through multiple implementations in the context. While the field of…

The present study has investigated the occurrence of the English anaphoric expressions, he/she, in L2 grammars. Adult Chinese learners of English were evaluated on whether they were able to provide a correct semantic interpretation of these pronouns when they appeared in complex sentences (subordinate + matrix) and correlative structures. Results…

This study examines the variable occurrence of preposition duplication in contexts of coordination in Spanish (e.g., "Fui con mi madre y (con) mi padre"). We build on previous research on this variable morphosyntactic phenomenon (namely, prepositions in contexts of coordination) by expanding the type of data and the independent variables…
