Addressing Higher Education Issues Of Latino Students In Greenville County, South Carolina, Sandra Elizbeth Portillo De Yúdice

Walden Dissertations and Doctoral Studies

Latino college enrollment rates in South Carolina do not reflect the overall increase in the Latino population in the state, which suggests that schools, colleges, and universities may be unprepared to serve the unique needs of Latino students. Consequently, Latino students are less likely to pursue opportunities in higher education than their non-Latino counterparts, which raises significant public policy concerns about equity and the potential economic contributions of the Latino communities. The purpose of this narrative policy analysis (NPA), based upon critical race theory, was to explore the perceptions of Latino students, parents, and advocates related to opportunities in pursuing …

A Comprehensive Analysis Of Computer Use Among African Americans, Kandice Lauren Smith

Walden Dissertations and Doctoral Studies

On average, African Americans receive lower wages in the workplace due to lack of advanced technical skills. The reason for technical deficiency among some African Americans is often lack of exposure to IT resources at an early age. The purpose of this ethnographic study was to identify and explore the factors that contribute to lack of IT resources available to some African Americans to cultivate IT skills. Information literacy theory formed the conceptual framework, which focused on information resources that African American and Caucasians use in the workforce for problem solving and retrieving information. Data were collected by conducting face-to-face …

Increasing Student Interest In Poultry Science Careers Through 4-H, Peggy Lynn Armstrong

Walden Dissertations and Doctoral Studies

The demand for poultry science graduates to fill available positions in the poultry industry continues to increase. At the same time, there are not enough graduates to fill the positions. The purpose of this study was to investigate the implementation of the poultry curriculum in the 4-H program and student recruitment through the 4-H program into the Poultry Science Department. The targeted populations were 4-H leaders who implement the poultry curriculum and university students who were currently studying poultry.

Success Factors For Women Of Color Information Technology Leaders In Corporate America, Annette Skervin

Walden Dissertations and Doctoral Studies

The 2013 United States Census data documents the significant underrepresentation of women of color in the information technology (IT) field. Women of color (Black, Hispanic, Asian or self-classified as non-White) represent an untapped resource in an industry with a low unemployment rate, high starting salaries, and a projected 18% growth rate by the year 2022. Prior researchers have studied White women in IT and have not provided a voice to women of color leaders. The specific problem addressed was the under-representation of women of color IT leaders in corporate America. The purpose of this phenomenological study was to investigate the …

The General Abilities Index As A Third Method Of Diagnosing Specific Learning Disabilities, Kristin M. Sims-Cutler

Walden Dissertations and Doctoral Studies

Many studies have investigated problems with the ability achievement discrepancy (AAD) method of diagnosing specific learning disabilities (SLDs). The definition of an SLD includes the presence of a deficit in one or more cognitive processing systems. Researchers in other studies found that the AAD method overdiagnoses English language learners and students from low socioeconomic backgrounds, and underdiagnoses students with cognitive processing deficits. Although SLD diagnostic methods have been widely researched, much less information is available regarding SLD diagnostic methods that predict important student outcomes, such as high school completion. The General Abilities Index (GAI) is an SLD diagnostic method that …

A Predictive Model For Dementia Risk In Elderly Adults With Prediabetes, Susan Elizabeth Alford

Walden Dissertations and Doctoral Studies

Dementia is a serious public health concern in the United States, with a prevalence of 5.2 million. There is currently no effective way to prevent or cure dementia, and the precise etiology is unknown, but it appears there are multiple risk factors. Prediabetes (PD) has been identified as a risk factor although the scientific evidence is conflicting.

The Relationship Between Family, Personal, And School Variables And The Math Achievement Of Elementary Students, Regina Wicker Kerr

Walden Dissertations and Doctoral Studies

School administrators and teachers must determine the factors most associated with academic success in order to meet the academic needs of all students. Researchers have identified general risk factors such as student socioeconomic status (SES), but there may be additional unidentified factors correlated to student achievement. The purpose of this study was to explore the relationship between a set of school, family, and personal demographic variables and students' math achievement. Bandura's social learning theory, Vygotsky's zone of proximal development, and Feurestein's mediated learning experience served as the guiding frameworks for this study. A descriptive correlational design was used to examine …

The Impact Of Common Core Professional Development On Teaching Practices, Elisabeth S. Kannenberg

Walden Dissertations and Doctoral Studies

The adoption of the Common Core State Standards (CCSS) in Mathematics represents a challenge for public educators due to the broad scope of required instructional change. This case study investigated the implementation of a professional development (PD) series across 11 elementary schools, designed to address the problem of insufficient teacher preparation in CCSS pedagogical shifts. Grounded in Vygotsky's social learning theory and constructivism, the training was intended to enhance teacher skills through collaborative, inquiry-based learning. The research questions included in the study examined math teaching practices before and after the implementation of the district training. Through questionnaires and interviews, perceptions …

Grounded Labels From The Behavioral International Economic Development Growth Path Model On Economic Development Patterns From 2002-2012, Kenneth Thomas Davis

Walden Dissertations and Doctoral Studies

Economic models generally fail to adequately measure positive and negative growth paths in development through agrarian, industry, and service economies. The purpose of this grounded theory study was to design a new model that could accommodate both directions of growth and better measure development paths with particular attention to labors contributions. The theoretical foundation for this study was Walt Whitman Rostow's 5 economic stages of growth classifications. This Study attempted to find the most common economic growth path. While most development models use three to five classifications, this study used nine new classifications giving it a unique and specific look …

A Case Study Of Teachers’ And Administrators’ Experiences Integrating Project-Based Learning, Gastrid Harrigan

Walden Dissertations and Doctoral Studies

Implementation of project-based learning (PBL) has contributed to increases in students’ retention of concepts, engagement, and academic success. The problem for this study is that teachers’ and administrators’ experiences and perceptions have not been sought regarding the integration of PBL in the classroom at the school district. The purpose of this qualitative instrumental case study was to gain a deeper insight into the experiences of teachers and administrators implementing PBL. Centered on the theory of constructivism, the research questions focused on 10 teachers’ and 5 administrators’ experiences integrating PBL. Face-to-face interviews with participants and 10 classroom observations were conducted. Inductive …
