To meet the national and international call for creative and innovative engineers, many engineering departments and classrooms are striving to create more authentic learning spaces where students are actively engaging with design and innovation activities. For example, one model for teaching innovation is Innovation-Based Learning (IBL) where…

The results of an industry research survey showed, understanding Dissertation Research categories has not been the focused on many researchers and institutions. This research expands on machine learning methodologies using two similar datasets to answer these three questions: 1. Is there a way to track the trends of Pace University's Doctor of…

Children with autism spectrum disorder (ASD) show a wide range of developmental characteristics and differ from each other in terms of symptom presentation. This heterogeneity leads to difficulties when trying to individualize treatments that work for individual children with ASD. Therefore, identifying and understanding subgroups of children on…

Interdisciplinary research in computer science requires the development of computational techniques for practical application in different domains. This usually requires careful integration of different areas of technical expertise. This dissertation presents image and time series analysis algorithms, with practical interdisciplinary applications…

With the recent rise in popularity of social network sites, more and more personal information is becoming available online. Since a person's information is generally available in various formats across multiple sites, there are ever increasing interests in consolidating such personal information from multiple information sources. The goal of…

Vocabulary learning is a crucial factor in second language acquisition (SLA), yet there is no consensus as to how to present vocabulary in a way that facilitates learning. Little theory and scant empirical evidence support the claim that presenting words in semantic clusters facilitates vocabulary acquisition, yet most text books present SL…

This thesis consists of two parts. In Chapter 2, we focus on the spatial scan statistics with overdispersion and Chapter 3 is devoted to the randomized permutation test for identifying local patterns of spatial association. The spatial scan statistic has been widely used in spatial disease surveillance and spatial cluster detection. To apply it, a…

The study adapted an existing instrument to examine perspective transformation and its associated factors in participants of evangelical faith-based adult nonformal education in the Midwestern United States. Stratified random one-stage cluster sampling of 11 churches produced a nonprobability sample ( N = 597) that was significantly (p < 0.05)…

This dissertation was designed and conducted to examine perception of classroom grouping practices in elementary schools. It includes a comprehensive review of literature related to grade-level and within-class grouping practices over the past thirty years in American schools. A focus was gleaned from the literature that led to the design of a…

Federal policy makers and school leaders increasingly recognize middle school math as a turning point in students' academic success. An i3 scale-up grant allowed grant partners to conduct a large-scale implementation of PowerTeaching (PT), a research-based reform to increase student math achievement. In a mixed-methods study during the pilot phase…

Mixed-initiative clustering is a task where a user and a machine work collaboratively to analyze a large set of documents. We hypothesize that a user and a machine can both learn better clustering models through enriched communication and interactive learning from each other. The first contribution or this thesis is providing a framework of…

At the University of California, Los Angeles, the Test of Oral Proficiency (TOP), an internally developed oral proficiency test, is administered to international teaching assistant (ITA) candidates to ensure an appropriate level of academic oral English proficiency. Test taker performances are rated live by two raters according to four subscales.…

Due to the rapid advances in computing and sensing technologies, enormous amounts of data are being generated everyday in various applications. The integration of data mining and data visualization has been widely used to analyze these massive and complex data sets to discover hidden patterns. For both data mining and visualization to be…

Compared to urban/suburban secondary school students, traditionally underrepresented students in rural areas often do not enroll or attend 4-year colleges and universities because of limited high school resources. To address this problem, higher education experts have suggested that high school faculty may serve as catalysts to encourage increased…

Mixed-format assessments are increasingly being used in large scale standardized assessments to measure a continuum of skills ranging from basic recall to higher order thinking skills. These assessments are usually comprised of a combination of (a) multiple-choice items which can be efficiently scored, have stable psychometric properties, and…
