Data for this qualitative study were collected at one public, four-year research university in the southeastern United States in the fall 2015 semester using recorded personal interviews …

Evidence-Based Assessment In Adapted Physical Education- Affective Outcomes: A Meta-Analysis, Breanna L. Ketel

Cal Poly Humboldt theses and projects

Currently there is a lack of evidence about assessment in adapted physical education (APE) settings concerning the justification for methods or curricula being implemented by teachers in their classrooms, that is perhaps due to a lack of understanding of the central notion of evidence-based practices (Jin & Yun, 2010). The purpose of the current investigation was to conduct a meta-analytic review that evaluates assessment practices to determine the overall effect on specific student affective outcomes. A secondary purpose was to evaluate the moderating effects of different methodological, sample, and study variables. Electronic database searches were performed in SPORT …

This study investigated 2014-2015 school year data associated with 2,792 students in five high schools in five different school districts in rural remote Appalachian Kentucky. The goal was to see which advanced academic service was most associated with college ready students. College readiness was measured in …

Self-Regulated Learning In A Rural, South-Central Kentucky Middle School, Tammy Dungan Board

Online Theses and Dissertations

Self-regulated learning is a phenomenon recognized in nations with positive results on international assessments, such as the PISA (Program for International Student Assessment; IES, 2012). This qualitative, non-evaluative study sought to determine the presence of self-regulated learning in a rural middle school in the south-central United States by utilizing a phenomenological approach.

Self-regulated learning is a practice based upon the constructivist learning theories championed by theorists such as Bandura (1995) and Vygotsky (1978). Zimmerman (1990) coined the term self-regulated learning, which reflects a method by which students are responsible for their own learning through four stages: pre-planning, monitoring for progress, …

Black Minds Matter: Black Student Perceptions Of Three Kentucky Regional Comprehensive Predominantly White Institutions And The Role Of Campus Support Initiatives In Reducing The Frequence Of Stop-Out And Drop-Out, Christopher W. Blakely

Online Theses and Dissertations

According to the National Center for Education Statistics (2015), between 1996 and 2008, Black (African-American may be used interchangeably with Black, as defined through this study) college students had the lowest graduation rates among racial groups at four-year public institutions. Furthermore, more recent provisional data from the National Center for Education Statistics for 2008-2013, further support continued disproportional retention and graduation rates of Black college students. Therefore, given this, the present study examined the relationship between academic achievement and an increase in Black students' satisfaction with their college experience at Predominately White Institutions (PWIs) and institutionally funded supportive associations for …

Effectiveness Of A Corequisite Delivery Model For Developmental Mathematics, Katherine E. Fair

Online Theses and Dissertations

The purpose of this quantitative quasi-experimental study is to determine the effectiveness of a corequisite delivery model for developmental math students at a 4-year public institution. Nationally, close to fifty percent of incoming college students are placed in non-credit bearing remedial courses (Complete College America, 2012). Students must pass the remedial course before they can take the gateway college-level course. Data show that the traditional delivery of a non-credit-bearing remedial course before taking a credit-bearing course appears to help only a small percentage of students (Complete College America, 2012). The low pass rate of remedial courses supports the current trend …

Student Perceptions Of The Honors Program At An Appalachian Community College, Melissa Renee Helton

Online Theses and Dissertations

Gifted students in the United States are often underserved. Collegiate honors programs are a proven way to provide for gifted students' special needs. Many gifted students attend community colleges, and these institutions have a set of challenges to starting and maintaining thriving honors programs, including accusations of elitism and lack of resources. Community colleges in Appalachia have an additional set of challenges to face, including high proportions of first generation students, rurality, and poverty. Efforts for thriving honors programs need to be effective and efficient at meeting gifted students' needs, but there is little research on the programs at these …

Uncovering The Processes And Consequences Of Egyptian Immigrant Parental Involvement In Their Children’S Education: Bridging Cultural Differences, Hend Shalan

Theses and Dissertations (Comprehensive)

Abstract

For more than a decade, researchers have concluded that immigrant parents face several barriers to becoming involved in their children’s education. All studies agree that language and cultural differences are the most significant barriers to immigrants’ involvement in their children’s education, yet we know little about what these cultural differences are and how these cultural differences influence the school involvement of immigrant parents. This study integrates theories of cultural differences, acculturation, and culture shock and the corresponding literature to investigate the lesser involvement of immigrant parents in school-related activities.

A focused ethnographic design was employed and a thematic analysis …

Eighth and ninth grade variables were tested separately to avoid multicollinearity issues. The second series …

Assessing Acquiescence In Surveys Using Positively And Negatively Worded Questions, Amy C. Hutton

Theses and Dissertations

The purpose of this study was to assess the impact of acquiescence on both positively and negatively worded questions, both when unidimensionality was assumed and when it was not. To accomplish this, undergraduate student responses to a previously validated survey of student engagement were used to compare several models of acquiescence, using a priori goodness-offit statistics as evidence for model fit, in order to develop a model that adequately accounted for acquiescence bias. Using a true experimental design, undergraduate students from a variety of classes at a large, urban university were randomly assigned to one of three versions of the …

Robustness And Comparative Power Of Welch-Aspin, Alexander-Govern And Yuen Tests Under Non-Normality And Variance Heteroscedasticity, Ayed A. Almoied

Wayne State University Dissertations

Classical statistical tests are used in many disciplines such as education and psychology. Such tests are based on certain assumptions (e.g., normality and homoscedasticity) that are must to be met in order to produce accurate results. Violation of such assumptions is a common problem researchers encounter, particularly when analyzing real data. When such assumptions are violated, the effectiveness and efficiency of tests to control over the probability of a Type I error and maintain a relatively level of statistical power will be substantially affected.

Alternative modern and robust statistical tests such as Yuen test for trimmed means and the Alexander-Govern …
