In the ever-changing digital era, the surge of online informal language learning platforms has revolutionized the way we learn new languages. This dissertation delves into the critical role of interactional feedback (IF) in synchronous computer-mediated communication (SCMC), a cornerstone for optimizing these digital learning spaces. Anchored in…

In English as a lingua franca (ELF) communication, in which English is used as a common language among interlocutors of different first languages, successful communication often features communication strategies that enhance mutual understanding and relationship management. Although prior research suggests that including such strategies in English…

The purpose of this paper was to study the effectiveness of language acquisition using speaker instruction and listener instruction and examining the emergence of bidirectional intraverbals using a non-sense language. Current research suggests that speaker type instruction is more effective in aiding untrained relations (Contreras et al., 2020;…

Writing in English is considered an important skill for ESL learners, and qualified teachers are needed in order to provide the students with written corrective feedback (WCF). Much previous research on WCF has looked at its overall effectiveness, with less attention paid to the teachers' perceptions of WCF methods and expected outcomes when they…

Leveraging the effectiveness of Concept-Based Language Instruction (C-BLI) in language teaching and learning, including in the teaching of specific linguistic features of target languages (Negueruela, 2003; Van Compernolle, 2012), pragmatic elements such as sarcasm (Kim & Lantolf, 2018), and even discipline-specific concepts (e.g., Casal,…

Millions engage in learning a Second Language (L2) using their mobile devices with a wide range of success. Concomitantly, there exists a growing interest in research on the effects of mobile-assisted language learning and predictors of learner outcomes (e.g., Loewen et al., 2020; Sudina & Plonsky, 2023). However, few of these apps and studies…

According to Diane August (2002), at the Center for Applied Linguistics, Multilingual Learners (MLs) spend less than two percent of their school day in oral language development. Echevarria and Goldenberg (2017) support that creating numerous opportunities for ML students to speak will accelerate their vocabulary and oral language development to…

Text messaging is the most popular form of communication (Lionbridge, 2019; Ceci, 2022), and mobile phone ownership is high, especially among university students (Chen & Denoyelles, 2013). Research on mobile language learning is increasingly found on the forefront of computer-assisted language learning (CALL) (Loewen et al., 2019; Stockwell,…

Students studying in beginning level foreign language classrooms often lack the opportunity to speak spontaneously (Kogan, 2023). Task-Based Language Teaching (TBLT) is a pedagogical approach to language instruction that advocates for the use of tasks to develop learners' second/foreign language (L2) abilities. Games can act as tasks that prepare…

This qualitative study explores the current practices of K-12 foreign language teachers (FLTs) in using the target language (TL) within an urban school district in the Midwest United States. Focusing on how FLTs engage in professional development (PD) to optimize their TL use in the classroom, the study investigates the strategies and knowledge…

The purpose of this study is to examine English new-language teachers' perceptions of online asynchronous and online synchronous professional development and teacher efficacy. English new-language students score significantly lower than others on standardized tests. This study analyzes online professional development for English new-language…

This study examined the effects of three subtitle conditions on English vocabulary learning, form recognition and meaning recall, from TED Talks videos while controlling for vocabulary size and initial knowledge of the target words. The participants, 105 Libyan students (16 males and 89 females) at intermediate English proficiency level, were…

In this dissertation, I will present social-cognitive frameworks that support the use of mental imagery for possible self enhancement; and articulate and evaluate a pedagogical intervention designed for the foreign language class. This intervention will allow students to explore and develop prominent and vivid mental representations (self-schemas)…

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…

Many elementary schools are shifting from traditional pull-out service models to push-in approaches, where multilingual learners collaborate with their English-only peers. However, research emphasizes the need for further investigation into implementing collaboration between elementary teachers and English Language Development (ELD) Specialists.…
