abstract: Arizona continues to implement the 4-hour ELD block despite opposition and concerns regarding is appropriateness and effectiveness. Research using state and national assessments show that English language learners continue to fall behind their English proficient peers in reading achievement even after the implementation of the 4-hour ELD block. In general, there is no proven direct correlation between the program and underachievement. This study evaluated the impact of the 4-hour ELD block on reading achievement by comparing similar reading-abled students that were in the program with students that were not. The study was conducted in a district located in a predominately Hispanic poor community in order to eliminate social and economical factors that could disadvantage one group over the other. The findings demonstrated there were no significant differences in the reading achievement between both groups, supporting arguments that the 4-hour ELD block has made little to no impact for ELL students. However, results demonstrate that early intervention may be significant in explaining increases in reading achievement. / Dissertation/Thesis / Doctoral Dissertation Educational Administration and Supervision 2019

Global Positioning System is a technology which is gaining acceptance. Originally developed for military purposes, it is being used in civilian applications such as navigation, emergency services, etc. A system-on-chip application merges different functions and applications on a single substrate. This project models a GPS receiver for a system on chip application. The GPS receiver, developed as a core, is intended to be a part of a navigation tour guide being developed. The scope of this work is the GPS C/A code on the L1 carrier. The digital signal processing back-end in a GPS receiver is modelled in this work. VHDL modeling of various communiation sub-blocks, detection and demodulation schemes is done. A coherent demodulation of the GPS signals is implemented. GPS receiver calculates the position based on the data collected from four satellites. Given four satellites, acquisition of the data from the signals is performed and data demodulated from the same. Synthetic data is generated for validation purposes. Code acuqisition and tracking of the GPS C/A signal is implemented. Cadence NC-Launch VHDL simulator is used to validated the behavioral VHDL model.

Implementation of behavior analytic interventions has traditionally relied on professionals possessing the required skills and expertise within controlled settings. While effective, this can be both expensive and time consuming. Research has demonstrated parent’s ability to implement a variety of interventions within the natural environment. As a result, parents are increasingly involved in treatment implementation. Getting the cooperation, support, and active participation of clients is essential to successful intervention. Therefore, buy-in at the earliest stages of treatment may result in the greatest effect. One of the earliest steps in treatment is the collection of data. Data collection methodology, validity, and reliability have been well studied. Parents as data collectors has also been reported. However, indications regarding the best data collection methods for parents to use, as well as any evident correlation between preference and accuracy, has not been reported. Through repeated measures using a multiple baseline across subjects, the study assessed the rate of acquisition of three data collection procedures by evaluating their performance accuracy before and after training. Preference rankings and perceptions for the data collection procedures were also obtained. Finally, the study examined correlations between preference for and proficiency with each data collection procedure. Results showed that training improved performance of Partial Interval Recording for 2 participants with one participant displaying skill mastery. Though training also increased participant performance using the Structured ABC method, skill mastery was not displayed. All participants achieved skill mastery using the Behavior Rating Scale method through repeated exposure.

The dissertation is an analysis of the history, current state, and possible future directions of the development of language policy in the Republic of Kazakhstan. Although language planning in the republics of the former Soviet Union has been a major subject of debate on government nation building agendas over the last two decades, the situation and implementation of language policies significantly differ in Kazakhstan due to the conditions of multilingualism and diglossia, in addition to other geographic and historical factors that resulted in the extended penetration of the Russian language during the Soviet era (Isayev, 1977:20). In the first chapter of the study, I trace the history of language legislation and political practices throughout the period of Russian-Kazakh diglossia (Fishman, 1967), a language situation in which the use of two unrelated languages (Kazakh and Russian) performed as high and low varieties at different levels prestige, and provide an analysis of important aspects of implementing legislative decisions and practices aimed at the development and promotion of the Kazakh language. The second and third chapters of this study are devoted to legislative documents and practices aimed at the modernization of Kazakh, especially with regards to the proposed switch from a Cyrillic to a Latin orthography, and amendments to the trinity of the Kazakh, Russian and English language status policies. This study of "language modernization" (switching from Cyrillic to Latin) is an attempt to define linguistic, literary, and social conditions and challenges, especially in the remote areas. The analysis of the modernization is based on the results of an extensive review of 1) official documents related to language policies; 2) on-line/magazine/newspaper and scholarly articles on Kazakh history, culture, language, education, and politics; 3) interviews with the officials of the educational departments, schools and language specialists.

The communicative language approach (CLA) dominates pedagogical practice in second language acquisition classrooms in the US. However, this approach does not emphasize independent pronunciation instruction, leaving learners to improve pronunciation on their own. This study explored the perspectives of English language learners (ELLs) being instructed via the CLA regarding the effectiveness of the CLA in providing intelligible pronunciation skills. The intelligibility principle of language served as the theoretical foundation underlying this study guided by research questions addressing how well the CLA met ELLs' pronunciation intelligibility needs and their perspectives on receiving independent pronunciation instruction to meet these needs. Using qualitative case study methods, the research questions were addressed through an analysis of interviews of 10 community college ELL adult volunteers who received instruction using the CLA as current or former students in the intensive English program, had linguistic skill levels ranging from beginner to advanced, and were graduates of U.S. schools. A typological analysis model was followed where the data were organized by themes, patterns, and identified relationships. Participants reported wanting to improve their pronunciation and that their pronunciation had improved with the CLA instructional strategies. Although all participants desired to receive some independent instruction in pronunciation, their preferred instructional modes differed. It is recommended that ELLs' perspectives be heard and that English as a Second Language educators instruct with the CLA while also providing explicit pronunciation instruction. The results of this study indicating student satisfaction with the CLA may elicit positive social change within the ELL community by providing a voice to ELLs.

Collaborative work in pairs or groups is a common practice in the workplace, in content courses, and in classrooms across languages, settings, and geopolitical boundaries. However, research on collaborative writing—working with a partner to jointly produce a text, including both planning and writing phases—is limited. In addition, it has resulted in contradictory findings, especially in terms of whether learners deliberate about language and how the composition process affects the written texts produced learners produce. The present study, carried out in a fifth-semester university Spanish Writing course, examines the process (i.e., interaction) and product (i.e., written document) of a collaborative writing module that focused on the creation of narratives. The analysis of learners’ collaborative dialogue produced during the planning and writing phases of the interaction focuses on: (1) at a macro level, how learners apportion their time while collaboratively planning and producing a written narrative (e.g., planning, formulating, revising); and (2) at a micro level, the types (e.g., discourse, grammatical, lexical, mechanical), frequency, and resolution (e.g., resolved, unresolved, resolved incorrectly) of their language-related episodes (i.e., the instances where they talk about the language they are producing and question their language use). Learners’ jointly produced texts were examined analytically in terms of complexity, fluency, and accuracy measures, as well as holistically using a rubric. Additionally, a microdiscourse analytic approach was used to examine the means by which members of a collaborative pair position themselves as partners in a collaborative writing activity. Results indicate that a fully collaborative writing event is a productive site for co- constructed learning as students pool their knowledge to solve language-use problems, particularly those related to word choice and grammatical structures. Additionally, the texts composed collaboratively are of higher quality, based on several of the measures utilized, than texts composed individually by members of the collaborative pair. Finally, implications for implementing collaborative writing tasks in L2 classrooms are discussed.

Master of Arts / Department of Modern Languages / Young-Ok Yum / Writing well, especially in English, is an asset to anyone who aspires to succeed in the academic or other professional fields in this age of English as a lingua franca. Numerous scholars have investigated errors committed by English-as-a-foreign-language (EFL) learners. However, to date there is no empirical study on the error patterns displayed in native Dari speakers’ EFL writing in English and in Dari. The present study investigates error occurrences in 20 native Dari speakers’ English and Dari writing. These participants were English majors attending Balkh University, in Mazar-i-Sharif, Afghanistan. Most of the participants self-identified their English proficiency levels as “advanced.” The data were collected through convenience sampling of the students enrolled in EFL writing courses who voluntarily participated in two writing tasks of different levels of difficulty; they completed these first in English and then a week later in Dari. In order to observe any patterns, all spelling and word choice errors were identified by three independent judges (one Dari instructor at BU, one native-American-English-speaking graduate student in the English Department, and the author who is bilingual and works as an English instructor). All three worked separately initially and then discussed any discrepancies together in person (English) or via Skype (Dari), until they reached consensus. The analysis, concerning the three research hypotheses, supported these findings: (1) as predicted, the native Dari speakers committed a variety of errors similar to learners from previous studies; (2) as predicted, the participants made fewer errors in English than in Dari; and (3) counter to the hypothesis, the results indicated that the participants, when writing in Dari, demonstrated more errors in the simpler tasks; yet, the participants committed more errors in the more complex (versus simpler) English writing task, consistent with this hypothesis.

This research looks at the use of PowerPoint as an instructional tool for teaching English language learners (ELL) who studied in a language program at a state university in the Pacific Northwest. The purpose of the research was to discover and to explore the perceptions of PowerPoint supported teaching and learning that were held by the students, the instructors, and the student researcher. PowerPoint is one of the most commonly used technologies in classrooms, and its projection on screens has become a fundamental part of many students' daily routine. The basic design of this research study is based on Stringer's (2004) action research model, which operates on a repeated circle of reflecting, planning, acting and observing. This action research was generated by all participants, guided by instructors, and monitored by the planned objectives of the study's outcomes. A constructivist approach was used to understand the process of teaching and learning with PowerPoint, and feedback (questionnaires, interviews, and personal communications) was collected from the students in order to help instructors and the student researcher to determine the students' needs. There are four main sets of data in this study—data from students' questionnaires, from students' interviews, from instructors' interviews, and from the student researcher's classroom observations. Students were given questionnaires at the ends of weeks two to ten, and two students from each class were selected to be interviewed. Instructors were interviewed both at the beginning and at the end of the term. The student researcher observed all classes starting week two, and wrote notes which were included as part of the data. / Graduation date: 2012
