Counterfactuals are a type of conditional sentences used to convey situations that do not correspond to reality. Tense morphology is a core ingredient to encode counterfactuals in English and most Indo-European languages.

Due to the shortage of World Language and English as a Second Language teachers, recruiting, retaining, and supporting aspiring second language teachers in the completion of their teacher licensure program is crucial. One barrier to the profession for these teachers is edTPA. Research has suggested that non-native English speakers (NNES) who…

Research on language learners' attention suggests that manipulating attention is beneficial in the language learning process as it facilitates the "noticing" of specific linguistic aspects. The current study investigated the effects of directing learners' attention to segments and prosody in English phonetic training. Korean learners of…

The problem is English language learners (ELLs) in adult education and college programs in the United States need support in achieving learning goals due to a lack of qualified English as a second language (ESL) teachers in their home countries. The purpose of this basic qualitative study was to understand how ELL students in Indiana perceive the…

This qualitative dissertation focuses on intercultural communicative competence (ICC) in a video-mediated environment, as ICC is considered to be one of the most vital skills language learners need to have in the 21st century to successfully communicate and interact with their interlocutors. More specifically, the aim of my dissertation research…

The problem addressed in this study was that second language learners have difficulties pronouncing some English consonants that are not part of their language. Such errors occur because of first-language interference. The purpose of this qualitative case study was to explore the perceived effectiveness of using minimal pair training to…

When acquiring a second language, learners must become able to perceive the difference between novel sounds ("discrimination") and also associate strings of sounds with distinct vocabulary items ("lexical encoding").

Second language learners constitute a significant and expanding portion of the global population and there is a growing demand for tools that facilitate language learning and instruction across various levels and in different countries. The development of large language models (LLMs) has brought about a significant impact on the domains of natural…

This study investigated English phonological awareness in adult native speakers of English (L1) and in relation to their phonological awareness skills and proficiency in their German (L2). Most research in L1 phonological awareness focuses on younger children, their phonological awareness development, the relationship between reading and…

Native Arabic speakers used idiomatic expressions such as idioms, formulas, and collocations, in their daily communications. In learning Arabic as a second language (L2), effective communication requires "the ability to understand and use idioms appropriately and accurately in a variety of sociocultural contexts, in a manner like that of…

One of the challenges facing the field of Chinese language pedagogy in the second decade of the 21st century is how to train teachers of Chinese as a foreign language (CFL) to teach effectively in emerging education markets. Emerging CFL markets are the result of a widely perceived need to learn Chinese as a foreign language in places where…

Nonnative English speakers are often judged based on their accent, but accent is perceived as well as produced. Race, gender, and religion interact to create complex and nuanced figures of personhood (Agha, 2005) impacting teachers' perceptions of students. Teachers' individual differences, including language proficiency, exposure to language, and…

Language learners need to map a continuous, multidimensional acoustic signal to discrete abstract speech categories. The complexity of this mapping poses a difficult learning problem, particularly for second language learners who struggle to acquire the speech sounds of a non-native language, and almost never reach native-like ability. A common…

The present dissertation brings together research on heritage language acquisition and bilingual education and makes inroads into the limited research on heritage language development in school-aged bilingual children. This study explores how bilingual education, patterns of exposure, and lexical frequency shape adolescent Spanish heritage…

Arabic emphasis refers to the production of consonants resulting from a primary constriction in the dental or alveolar region and a secondary constriction in the back of the vocal tract, recognized as 'Emphatic.' These have contrastive consonants produced in the dental or alveolar region, recognized as 'Plain.' The existing research on emphasis in…
