Advances in Natural Language Processing (NLP) over the past decade have largely been driven by the scale of data and computation used to train large neural network-based models. However, these techniques are inapplicable to the vast majority of the world's languages, which lack the vast digitized text datasets available for English and a few other…

Explicit instruction in the academic language of disciplines is considered a major component of effective literacy development for adolescents (National Governors Association, 2010) and has become one of the standards in all disciplines. States have mandated that schools adopt teacher evaluation models and professional learning community (PLCs)…

This dissertation develops a cognitive model describing when children learn to group distinct sound segments (allophones) into abstract equivalence classes (phonemes). The allophones an individual acquires are arbitrary and determined by their particular input, yet are intricately involved in language cognition once learned. The proposed…

Teachers in Nevada have faced the problem of providing consistent, effective literacy instruction to elementary students, which impacts overall student achievement; only 48.3% of students in Clark County, Nevada were proficient in English Language Arts (ELA) in the 2018-2019 school year. This problem was explored from a case study perspective…

In the United States, early childhood educators are expected to follow the trend to enforce academic curriculum for preschoolers. This effort diminishes the value of play in the young developmental years of children. The purpose of this study was to explore the type of activities and strategies that promote development of language and literacy…

Academic vocabulary knowledge is central to reading achievement, particularly for students who have limited experiences with academic discourse outside of school. Yet many teachers devote little time to focused instruction in this area, because they may lack critical meta-linguistic and pedagogical knowledge. The purpose of this longitudinal…

This dissertation examines how English language learners in the Kingdom of Saudi Arabia (KSA) realize learner autonomy, especially in the context of the learner's meaning development via purposeful vocabulary acquisition. This project is a qualitative case study that engages both teachers and English learners as subjects over a prolonged period of…

At an international school in Taiwan, English learners have struggled to meet the U.S. national average in vocabulary on standardized testing instruments. This problem has become more significant since 2009. The purpose of this research was to conduct a case study on successful vocabulary teachers to determine their perceptions of effective…

Growing gaps in reading and vocabulary achievement between minority and majority student subgroups have led to an intense focus on implementing effective classroom instructional strategies. Prior research concerning teachers' perceptions of using explicit instructional strategies to teach vocabulary to underperforming students has been…

Although the field of school psychology currently calls upon practitioners to implement evidence-based interventions to address reading deficits, the literature base is limited and inconclusive when it comes to effectiveness of reading interventions at the high school level, especially with older adolescents with reading disabilities. The current…

This dissertation investigated the effects of technological mediation on second language (L2) learning, focusing, as a case study, on gains in listening perception of the subtle but important feature of pitch placement in Japanese. Pitch accent can be difficult to perceive for non-native speakers whose first language (L1) does not rely on pitch or…

The acquisition of vocabulary is an important aspect of young children's development that may impact their later literacy skills (National Reading Panel, 2000; Cunningham & Stanovitch, 1997). Deaf children who are American Sign Language users, however, often have smaller vocabularies and lower literacy levels than their hearing peers…

The proliferation of online simulation games across the globe in many different languages offers Computer Assisted Language Learning (CALL) researchers an opportunity to examine how language learning occurs in such virtual environments. While there has recently been an increase in the number of exploratory studies involving learning experiences of…

The purpose of this study is to answer this question: Which is academically superior for young children, full-or half-day kindergarten? This inquiry-oriented case study was designed to compare and contrast students who attended half-day versus full-day kindergarten programs in a suburban public school district. The study is necessary because the…

This study examined the effects of a home-reading program on parent-teacher communication and on the ability of parents to select reading material for their children. In this qualitative case study, parents of 4th grade students participated in a reading homework program with their children. Using constructivist theories, the study's…
