If You Build It, Will They Come? An Autoethnographic Account Of Starting A School And Year One, Courtney Rae Luce

Dissertations

This autoethnographic research was a qualitative analysis of the process of starting a school and running it in the first year. While this research explained some of the process, it is not a guidebook for starting schools. Instead, this narrative was meant to tell about the experience in order to inspire others in education to try something new or different. The significance of the research came from the need for a change in education and the power of narrative to inspire change. Using autoethnography as my methodology and reflection and layered accounts to tell the narrative, I explored the following …

The Effects Of Disability Labeling On Teachers’ Referrals Of Twice-Exceptional Children To Gifted Programs In Saudi Arabia, Amra Abdulrahman Mohammad

Dissertations

The issue of biases associated with labeling students as gifted or as having a disability presents a significant challenge to educational professionals with regard to identification and the provision of services. In the presence of labels indicating giftedness, disability, and twice exceptionality, research consistently demonstrated biases on the part of parents, teachers, and even other students. These biases could prevent students from receiving the services they need to achieve their fullest potential (Bianco & Leech, 2010). The current study systematically replicated a study by Bianco and Leech (2010) and examined the influence of disability labels on teachers’ decisions to refer …

Nonparametric Approach To Multivariate Analysis Of Variance (Manova) Using Density-Based Kernel Methods, Hend Aljobaily

Dissertations

Density estimation and nonparametric methods have become increasingly important over the last three decades.

An Activity Theory Approach To Examining The Implications Of Developmental Mathematics Reform At An Urban Community College, Jennifer Ruth Zakotnik-Gutierrez

Dissertations

Developmental mathematics courses, designed to provide remediation for students who are identified as having skills below the college level, have long been a mainstay in community colleges. These courses fill a need and effectively prepare some students for college level math courses, providing access to mathematics courses and college programs they otherwise would not have had. However, a large majority of students experience developmental mathematics as a gatekeeper, rather than a gateway, to higher courses. As such, the status quo of traditional developmental mathematics programs is inequitable, denying access to college-level courses. Recognizing this equity issue as necessitating institutional change, …

Perceptions Regarding The Effectiveness Of Co-Teaching Practices To Support Students With Learning Disabilities In Secondary Inclusive Classrooms: Case Study, Aeshah Abdullah Alsarawi

A Multilevel Examination Of Unethical Pro-Organizational Behavior Decision-Making: The Role Of Citizenship Pressure, Moral Disengagement, And Moral Intensity, William Bryant

Dissertations

Unethical pro-organizational behaviors (UPB) are unethical behaviors that are intended to benefit the organization or its members. Research on this type of behavior typically involves assessing attitudinal and dispositional predictors of UPB but has largely failed to understand the process through which UPB occurs. One potential elicitation process could be through a perceived obligation that an employee has to help their organization, or citizenship pressure. By adapting Rest’s four stage model of ethical decision-making and social exchange theory, the current study aimed to identify how organizational identification might increase perceptions of citizenship pressure, and how citizenship pressure might influence elements …

The Experience Of Faculty Transitioning From Traditional To Non-Traditional Methods In The Community College Classroom, Christina Calentine

Dissertations

There is documented success with the use of active learning strategies in community college classrooms, yet instructors lack the necessary skills and incentives to develop these strategies. While faculty members may have an expertise in a particular discipline they often lack the necessary skills to recognize the specific academic needs of a student and respond and/or adapt to those needs. Many specialized degrees do not include pedagogical training as part of the required curriculum but community colleges are typified by diversity in student backgrounds and learning styles. This has led to increased attention to the implementation of a diverse array …

Student Perceptions Regarding The Use Of Purposive English In A Spanish As A Foreign Language Classroom, Kacey Booth

Dissertations

In modern American society, diversity is both challenged and celebrated, and inclusion is imperative. This ideology begins in the classroom. Oftentimes, this celebration of diversity, more specifically linguistic diversity, is most visible in Teaching English to Speakers of Other Languages (TESOL) classes and similar bilingual educational programs. In TESOL programs, students’ international identities are highlighted and students are often instructed using multilingual educational resources to scaffold their acquisition of English. Historically, foreign language teaching also utilized dual-language instructional methodologies. Such archaic teaching methodologies have since been replaced by more modern and immersive sociopsycholinguistic approaches such as Communicative Language Teaching. Such …

Can Ratings Of Item Location Enhance Statistical Item Parameter Estimation? Extending The Feasibility Of Unfolding Irt Models, Michael Mckenna

Dissertations

Research and development of modern psychometric methods such as item response theory have drastically changed the way we understand and carry out the measurement of psychological constructs. Despite this, there has been relatively little adoption by psychological researchers to incorporate these methods into their research. While multiple explanations are surely valid, one oft stated reason is the large sample size requirements of these methods. The sample size requirements of item response theory are needed so that effective estimation of item parameters can be carried out. In an attempt to make these modern measurement methods more accessible and feasible to psychological …

Examining Preservice Teachers’ Self-Efficacy Development Throughout Teacher Education, Jenny Christine Hernandez

Cross Language Information Transfer Between Modern Standard Arabic And Its Dialects – A Framework For Automatic Speech Recognition System Language Model, Tiba Zaki Abdulhameed

Dissertations

Significant advances have been made with Modern Standard Arabic (MSA) Automatic Speech Recognition (ASR) applications. Yet, dialectal conversation ASR is still trailing behind due to limited language resources. As is the case in most cultures, the formal Modern Standard Arabic language is not used in daily life. Instead, varieties of regional dialects are spoken, which creates a dire need to address dialect ASR systems. Processing MSA language naturally poses considerable challenges that are passed on to the processing of its derived dialects. In dialects, many words have gradually morphed from MSA pronunciations and at many times have different usages. Also, …

Quantitative analysis of brain imaging data using machine learning and data mining techniques can be advantageous not only to increase the accuracy of brain disorder …

Saudi Arabian Science Teachers And Formative Assessment In The Gender Segregated Male School System, Khalid Abdullah Kariri

Dissertations

Formative assessment is a key pedagogical tool that allows teachers to make instructional assessments in real time for the improvement of student learning. It gives students the opportunity to provide evidence of their learning thus giving teachers assurances that their hard work is not in vain. Formative assessment is commonly practiced in Western schools, while most Saudi science classroom teachers rely on end-of-unit summative assessment. A review of the literature reveals that very little research has been done related to Saudi teachers’ use of formative assessment in science classrooms. The goal of this dissertation was to address this absence of …

A Parametric Analysis Of The Sunk Cost Effect, Amanda F. Devoto

Dissertations

Sunk costs are previous investments of time, effort, or money toward a goal that cannot be recovered. People often honor sunk costs by continuing to pursue a goal, despite the availability of an alternative path that would pay off faster, a phenomenon called the sunk cost effect. Prior research has identified variables that influence the sunk cost effect. One variable found in hypothetical scenario-based research and in behavior-based research (Pattison et al., 2011) has been percent of goal completed. The current study was designed to (1) replicate and extend research by Pattison and colleagues and (2) compare results from the …

Undergraduate Educational Research Experiences In The Study Of Interior Design, Julia Virginia Pimentel Jiménez

Dissertations

Designers create social constructions (experiences and interactions) for human beings among themselves and with and within interior environments to enhance meaning in people´s lives (Poldma, 2011). Those social constructions are created through the design process developed by the interior designer; that process relies heavily on design research. Therefore, it is at the undergraduate level that the passion for research should start for interior design (ID) students. Faculty in ID programs need to encourage that passion by engage students in meaningful learning experiences such as how to ask questions about users, functions, activities, and aesthetics.

This study explored what types of …
