As technology continues to change human interactions, it has become increasingly important to create computer supported collaborative learning (CSCL) environments that enhance perspective taking to support constructive groupwork. To meet these aims, this study examined perspective taking before and after a social annotation activity that…

In this research study, an instructional intervention protocol is described. This intervention was designed to help teachers to engage English Learner students (ELs) in mathematical problem-solving lessons and reasoning through discourse. The "Discursive Mathematics Protocol" (DMP) integrates Polya's classic problem-solving framework and…

People have many reasons to want to learn a foreign language: some want to enjoy foreign media in its original form, some need it for business or travel, personal enrichment, and so on. Roughly 1/6 of Earth's population's learn languages with logographic writing systems (LWS) such as Chinese, Japanese and Korean as their native tongues. These…

Orthography-phonology mapping in world languages exhibits variations. Extensive research has investigated whether orthographic-phonological consistency impacts the cognitive processing of written words. A major body of work has focused on the recognition of phonographic first language (L1) written words. Results show that the more transparent the…

The main purpose of this study was to investigate the effectiveness of written corrective feedback (WCF) in a Korean as a foreign language (KFL) context. The assumption that indirect feedback (IF) is more effective for L2 learners with higher-proficiency levels has yet to be fully corroborated, which necessitates substantial research-based…

Typically developing (TD) children, as young as four years of age, have demonstrated enhanced noun learning when orthographic representations are presented during learning tasks. This dissertation investigated the impact of orthographic support on word learning in diverse populations, focusing on children from a variety of clinical categories…

Within the field of linguistics, whether considering language contact situations (Weinreich, 1979) or foreign language education (Lado, 1957), the topic of language transfer, especially as it relates to pronunciation, has always been an item of particular interest. While research on such transfer has mostly focused on various phenomena of the L1…

This dissertation investigates a typologically rare linguistic phenomenon found in Irish from three different perspectives: how it challenges phonological theory, how it is used by contemporary speakers, and how its written representation affects its acquisition. Initial consonant mutation (ICM), as it appears in the Celtic languages, is known to…

The problem addressed in this quantitative experimental study was that students were having more difficulty learning from audiovisual lessons than necessary because educators had eliminated textual references, based on early findings from CLT research. In more recent studies, CLT researchers estimated that long-term memory schemas may be used by…

This dissertation study aims to theorize an instructional practice which I labeled languaging thinking. Languaging thinking is conceptualized as a social practice in which teachers and students make visible and discuss how to think about a particular task, topic, or activity, through the use of spoken and written language and related semiotic…

Adolescent newcomer students bring a wealth of linguistic and cultural resources to their learning environments--resources that become even more dynamic when combined with those of their peers. While a significant body of research has explored students' deployment of multilingual resources through translanguaging, most of this work does not…

Young deaf learners often have difficulty mastering the important skill of decoding print and developing phonological awareness necessary to become successful readers. The research question for the study was: How do K-2 deaf learners demonstrate literacy development when teachers of the deaf use instructional video with visual portrayals of…

As China increasingly internationalizes its higher education system, growing numbers of Chinese learners and expatriate instructors meet in the classroom, engaging one another from their disparate cultural and pedagogical standpoints. Despite its widespread occurrence, the phenomenon of Chinese learners and Western instructors engaging one another…

Students who engage in mathematical arguments in classrooms take part in an important practice involving reasoning and justification. As a mathematical practice, argumentation involves using both conceptual and procedural reasoning to justify a claim. Even though argumentation can occur in discussions where one asserts and defends their claim…

This mixed-methods study examined the lived experience of adult English Language Learners (ELLs) in classrooms led by native speaking teachers, compared with their experience in classrooms led by non-native teachers. The socio-cognitive approach to language and emergent common ground framed the development of the English classroom as a Community…
