A Partial Simulation Study Of Phantom Effects In Multilevel Analysis Of School Effects: The Case Of School Socioeconomic Composition, Hao Zhou

Theses and Dissertations--Education Sciences

Socioeconomic status (SES) affects students’ academic achievement at different levels of an educational system. However, misspecified Hierarchical Linear Model (HLM) may bias school SES estimation. In this study, a partial simulation study was conducted to examine how misspecified HLM model bias school and student SES estimation.

The result of this study can be summarized by four important points. First, based on partial simulation procedure, phantom effects of school SES and student SES are real. Second, characteristics of phantom effects are generalized. The stronger the correlation between prior science achievement measure and present science achievement measure, the greater the decrease in …

Navigating The Career Pipeline: Experiences Of Female Community College Presidents, Andrea Allen Deal

Theses and Dissertations--Education Sciences

Despite holding a majority of lower and middle management positions in public two-year institutions, women still hold only one-third of current community college presidencies. This study explored the gendered phenomenon of navigating the career pipeline in higher education to reach the office of community college president. The purpose of the study was to examine the educational backgrounds and career paths of recently-appointed female community college presidents, as well as the barriers and sources of support they encountered while navigating the career pipeline.

A phenomenological approach was utilized for this qualitative study. Data was primarily collected using semi-structured interviews. Additional sources …

Complexity Leadership: The Role Of Teaching And Learning Center Leaders In Online Learning At Small, Private Colleges, Tyler D. Watts

Theses and Dissertations--Education Sciences

As online learning continues to grow and became an integral component of many higher education institutions (Allen & Seaman, 2017), the role of leadership in guiding those online learning initiatives differs from institution to institution. At small, private colleges and universities, where online learning is seeing greater enrollment and growth (Clinefelter & Magda, 2013), teaching and learning centers (TLC) often have involvement in guiding and shaping online learning initiatives. This study investigated the role of TLC leaders in leading online learning initiatives. The value of this study is an examination of leadership during a period of transformation and change that …

Assessing The Model Fit Of Multidimensional Item Response Theory Models With Polytomous Responses Using Limited-Information Statistics, Caihong Rosina Li

Theses and Dissertations--Education Sciences

Under item response theory, three types of limited information goodness-of-fit test statistics – M₂, M_ord, and C₂ – have been proposed to assess model-data fit when data are sparse. However, the evaluation of the performance of these GOF statistics under multidimensional item response theory (MIRT) models with polytomous data is limited. The current study showed that M₂ and C₂ were well-calibrated under true model conditions and were powerful under misspecified model conditions. M_ord were not well-calibrated when the number of response categories was more than three. RMSEA₂ and RMSEA_C2 are …

A Leadership Perspective On Family Engagement: Qualitative Content Analysis Of Secondary Data, Stephanie Anderson

Theses and Dissertations--Education Sciences

The purpose of the study was to explore the leadership actions and activities that contributed to the implementation of a schoolwide family engagement initiative in a school. A qualitative content analysis of secondary data design was used to investigate the intentional actions and activities of a school leadership team during the implementation of a family engagement initiative within an elementary school. The Coherence Framework (Fullan & Quinn, 2016) provided a lens for which to investigate schoolwide change across drivers and sub-drivers.

The findings of this study describe intentional leadership actions and activities when communicating with families, conducting formal assessments, and …

The Effect Of Increased Physical Activity On Academic Performance, Lauren Michelle Willis

Theses and Dissertations--Education Sciences

Increased levels of obesity, particularly among American youth, have consistently been cause for concern over the last few decades. Additionally, the amount of time youth spend being active throughout the day has consistently decreased. Physical activity levels among school-aged children in America are effected by any number of reasons, but this study points to the possibility of time spent being physically active during the school day having the greatest effect on a student’s overall level of physical activity. Increased pressures from different entities on local schools to improve student performance on standardized test scores have contributed to a decline in …

Speaking Their Truth: Black Women's Perspectives On Executive-Level Administration In Higher Education, Tanja N. Bibbs

Theses and Dissertations--Education Sciences

While Black women have etched a place for themselves as leaders within colleges and universities, few have advanced to the most senior levels of postsecondary administration and they remain underrepresented in those type of roles (Gamble & Turner, 2015; Jackson & Harris, 2007; West, 2015). Scholarly research has explored Black women’s experiences as institutional leaders (Davis & Maldonado, 2015; Smith & Crawford, 2007; Waring, 2003); yet the phenomenon of executive-level higher education administration, specifically as it relates to Black women’s perspectives, is not well known (Enke, 2014; Jean-Marie, Williams, & Sherman, 2009). Moreover, research that directs attention to Black women’s …

Differential Item Functioning Among English Language Learners On A Large-Scale Mathematics Assessment, Ruixue Liu

Theses and Dissertations--Education Sciences

English language learner (ELL) is a term to describe students who are still acquiring English proficiency. In recent decades, ELLs are a very rapidly growing student group in United States. In school classrooms, ELLs are learning English and their academic subjects simultaneously. It is challenging for them to hear lectures, read textbooks, and complete tests in English despite of their inadequate English language proficiency (Ilich, 2013). As a result, the increasing number of ELLs in public schools has paralleled the increase in ELLs’ low mathematics performance (NCES, 2016).

Due to the popularization of international large-scale assessments in the recent decade, …

Validation Of A School Climate Instrument Using A Rasch Rating Scale Model, Audrey Conway Roberts

Theses and Dissertations--Education Sciences

A new ESSA indicator of school quality and student success provides flexibility to broaden a states’ definition of school and student success. Educational research has found school success is in part determined by a school’s climate and should be considered in improvement/reform strategies (Cohen et al., 2009; Thapa et al., 2013). Yet, school climate research is often difficult and time consuming, and employs a variety of conflicting definitions and dimensions, instruments, and empirical approaches to determining school climate. Given these significant limitations with current measures, the purpose of this study was to validate an instrument measuring school climate based on …

Superintendents And The Micropolitics Of Innovation In Rural School Districts, Catherine Nunn Lawless

Theses and Dissertations--Education Sciences

Research shows that public school districts that follow traditional means of instruction and assessment are insufficiently preparing students for success in the today’s global world. As a result, students are entering into higher education institutions and the workforce without the necessary skills to succeed in these 21^st century environments. Extant literature suggest that there is a broad consensus on this perspective in public and private sectors nationally and globally. Evidence shows that some school district superintendents and their respective school boards continue to focus on improving the current practices and student academic performance and assessment. Other instructional leaders recognize …

Online Language Acquisition And Leadership In Higher Education-Governed Intensive English Programs: A Rasch-Based Diffusion Of Innovation Study, James Brandon Decker

Theses and Dissertations--Education Sciences

Research has indicated accredited, U.S. higher education-governed intensive English programs (IEPs) often struggle financially due to a scarcity of resources (namely students) because of political and global economic factors and increased competition (ICEF Monitor, 2017; IIE, 2017; Ladika, 2018; Soppelsa, 2015). However, few IEPs advertise online language acquisition (OLA) courses despite the increase in online study methods at the higher education institutes governing the programs and its use by competitors. The purpose of this study was to determine the status and extent of OLA diffusion in U.S. IEPs, how IEP directors and faculty perceived OLA, and whether they perceived themselves …
