Factors that Influence Under-represented Minority Students in Science, Technology, Engineering, and Mathematics attending a Predominately White Institution, the Role of Retention

White, Vemitra Mornit 07 May 2016 (has links)
The quality of STEM in higher education is widely recognized as an important issue. There is tremendous amount of concern around persistence, retention, and attrition for under-represented minority students (URMs) majoring in STEM disciplines. Retaining this population of students in the different STEM discipline is also a major concern for educators and policy makers in the United States. Student interest is there, however, problems arise when course work becomes challenging. As a result, students tend to lose confidence and change their majors. The purpose of this study was to discover factors that are related to persistence in STEM majors for a group of URMs who participated in a summer bridge program between 2008- 2014 at a Predominately White Institution of higher learning. In this study the researcher used archived data and quantitative research methods to identify different factors. Data analysis was conducted to answer the eight research questions that guided the study. To answer research question 1, descriptive statistics were used to analyze data that provided a comprehensive description of the students’ high school and college academic performance. One way ANOVAs were computed to analyze data for research questions 2-6, whereas Chi –Square Tests of Independence were used to analyze data for research questions 7 and 8. The researcher examined data for 232 URMs who participated in a summer bridge program during 2008-2014 academic years. The findings for research question 1 revealed that URMs represented in this study were college ready according to their average ACT scores and high school GPAs. An examination of two gatekeeper courses (Calculus and Chemistry) revealed that majority of the students passed with a letter grade of C or below. The findings for research questions 2-6 revealed statistically significant differences for URM students who persisted in STEM majors. They included ACT composite scores, ACT subscale scores all expect for reading, first semester GPA, first year GPA, sophomore year GPA, and number of credits earned through sophomore year. The findings for research questions 7 and 8 revealed that persistence was not influenced by gender or STEM major.

The Effects of Institutional Structure of Predominantly White Land-Grant Colleges and Universities in the Southeast on African American Graduation Rates in Engineering

Clinkscales Verdell, Angela Denice 08 December 2017 (has links)
The U.S. Department of Labor reports that only 5% of U.S. workers are employed in fields related to science and engineering, yet they are responsible for more than 50% of our sustained economic expansion (U.S Department of Labor, 2007). Furthermore, minorities makeup 0.0025 % (1/400) of that Science, Technology, Engineering, and Mathematics (STEM) workforce. Methods are currently underway to understand and address the attrition of minority students in the STEM workforce. The problem of underrepresentation of minorities (URMs) in STEM careers continues to result in a “leaky pipeline” where URMs have cited institutional factors such “chilly campus” climates as barriers to persistence and success (Tinto, 1993 Astin, 1993, Seymour & Hewitt, 1997). Despite the “separate but equal” challenge surrounding the early establishment of US educational institutions, the US remains a model for accessible and affordable education. Social equity concerning URM student outcomes in STEM has become a prominent topic of discussion. Researchers and practitioners seek to understand why the growing disparity exists for minority students as this underserved population represents those that higher education has been least successful in educating (Bensimon, 2007). This daunting assertion of disparate educational attainment by race and ethnicity is alarming. In this study the researcher used archived data and web content analysis to conduct a quantitative study to understand the effect of institutional constructs on the graduation rate of African American students pursing engineering degrees. The research model included hypotheses resulting from independent institutional variables of African American engineering students, institutional size and type, institutional endowment and social equity initiatives. The dependent variable of African American engineering student graduation rates was considered in relation to each independent variable. To answer research questions 1 and 2, descriptive statistics were used to analyze data that provided a comprehensive description of the institutions’ resources and social equity initiatives. Spearman’s Rho with ordinal variables and a small number of cases were computed to analyze the data. This analysis revealed a positive correlation between the numbers of social equity initiatives and engineering graduation rates of African American students at PWI southeast land-grant colleges and universities located in the southeastern portion of the U.S. The outcomes of this study help to expand the literature on underrepresented minority (URM) STEM retention in higher education. Understanding the effects of institutional constructs on the success of African American engineering students allows for the implementation of effective intervention strategies that will help to increase the pipeline of well-prepared African American engineers for the global STEM workforce.
