This thesis aims to provide a subjectivist account of women and people of colour's leadership experiences within a specific social context, in order to offer a contribution to the largely acontextual leadership literature. A multi-level, intersectional analytical framework was used to explore the experiences of people who are marginalised in their attempt to access and practice leadership. The study used the South African private sector as a social context with unique and interesting gender and race dynamics to conduct this case study. The experiences of significantly underrepresented groups in organisational leadership were explored by means of 60 in-depth, face-to-face interviews with women and people of colour in strategic leadership positions, aspiring leaders in leadership development programmes and key informants, all from the South African private sector. Interviewees were grouped according to their intersectional identities and responses were analysed considering individual-level challenges and enablers, organisational-level challenges and enablers and also by considering responses within the socio-historic and socio-legal context. Key findings include evidence of the problematic nature of theorising leadership as an element of the leader; support for theoretical frameworks of occupational segregation and embodied social identities; evidence of the internalisation and rationalisation of institutionalised discrimination; evidence of social identities being mutually constituting, reinforcing and naturalising; evidence of the conflation of gender, race and merit in the equality debate; as well as a strong aversion among research participants towards positive discrimnination initiatives. The findings also suggest several areas of possible further research. This study addressed the limitations of leadership research, which is characterised by leader-centricism, romanticism, objectivism, gendered and racialised norms and additive theorising. Findings make theoretical and policy contributions by problematising merit, exposing leadership in the South African private sector organisations as a site of intersectional identity salience, disrupting key assumptions underpinning leader-follower relations, highlighting the potential for leveraging adversity and also by demonstrating the importance of leadership language in either disrupting or reinforcing inequality.

This nested multi-site case study uses data from interviews with thirty underrepresented students to explore how these students experience elite universities. Although greater numbers of underrepresented students are enrolling in university than ever before, those from non-traditional backgrounds are largely excluded from elite universities. Elite universities in the United States, England, and Scotland are all striving for increasingly higher levels of excellence, status, and funding to raise and maintain their global positions as university rankings continue to affect student choice and perception of value. The expansion of higher education during the past several decades has fostered discussions pertaining to the social characteristics of the student body, and whether enough is being done to include individuals traditionally excluded from higher education. Simply developing widening participation initiatives, however, does not eliminate inequality in the university system. This thesis considers discussions relating to higher education expansion, development of widening participation policy, costs associated with higher education, and the social characteristics and constructions of the underrepresented student in the three nations. The four key findings resulting from the student interviews are organised into the three themes of economic, social, and cultural capital. The first finding was that the students who lacked accessible economic capital were unable to participate in social events. The inability to participate produced feelings of exclusion. The second key finding was that students who were most debt averse reported the least amount of debt. This debt aversion meant some students worked nearly full-time or strictly managed their income. The third key finding was that students who were able to minimise their social and cultural differences, such as changing their accent, were more likely to report feelings of belonging. The fourth key finding was that, although the widening participation policy agenda focuses predominately on economic disadvantage and access, very little attention is given to elite universities’ habitus, which perpetuate privilege and complicate feelings of belonging. One of the most pronounced areas for further research that has come out of this study is whether the fear of stigmatisation in identifying widening participation students outweighs the potential benefits in acknowledging and creating a community for those students. Ultimately, the hope of this study is that, by understanding the experiences of such students who gain access to an elite university, we can learn from their experiences and how, moving forward, not only help a greater number of underrepresented students to attend these elite universities, but also support those students throughout their university years.

Students' retention in STEM-related careers is of great concern for educators and researchers, especially the retention of underrepresented groups such as females, Hispanics, and Blacks in these careers. Therefore it is important to study factors that could potentially influence students' decision to stay in STEM. The work described in this dissertation involved three research studies where assessments have been used in college chemistry courses to assess students' prior content knowledge, chemistry-self-efficacy, and attitude toward science. These three factors have been suggested to have an influence on students' performance in a course and could eventually be a retention factor. The first research study involved the development and use of an instrument to measure biochemistry prior knowledge of foundational concepts from chemistry and biology that are considered important for biochemistry learning. This instrument was developed with a parallel structure where three items were used to measure a concept and common incorrect ideas were used as distractors. The specific structure of this instrument allows the identification of common incorrect ideas that students have when entering biochemistry and that can hinder students' learning of biochemistry concepts. This instrument was given as pre/posttest to students enrolled in introductory biochemistry courses. The findings indicated that some incorrect ideas are persistent even after instruction, as is the case for bond energy and the structure of the alpha helix concepts. This study highlights the importance of measuring prior conceptual knowledge; so that instructors can plan interventions to help students overcome their incorrect ideas. For the second research study, students' chemistry self-efficacy was measured five times during a semester of preparatory college chemistry. Chemistry self-efficacy beliefs have been linked to students' achievement, and students with stronger self-efficacy are more likely to try challenging tasks and persist in them, which will help them to stay in STEM. Using multilevel modeling analysis to examine potential differences in students' self-efficacy beliefs by sex and race/ethnicity, it was found that there were some differences in the trends by race/ethnicity. In particular, we found that for Hispanic and Black males the trends were negative when compared with White males. This study highlights the importance of measuring self-efficacy at different time points in the semester and for instructors to be aware of potential differences in their students' confidence when working on a chemistry task. The third research study involves the use of the Test of Science Related Attitudes (TOSRA) in an introductory chemistry course. A shortened version of the instrument that includes three scales, normality of scientists, attitude toward inquiry, and career interest in science was used. The first purpose of this study was to gather validity evidence for the internal structure of the instrument with college chemistry students. Using measurement invariance analysis by sex and race/ethnicity, it was found that the internal structure holds by sex, but it did not hold for Blacks in our sample. Further analysis revealed problems with the normality scales for Blacks. The second purpose was to examine the relationship between the scales of TOSRA, achievement in chemistry, and math prior knowledge. Using Structural Equation Modeling (SEM) it was found that two of the TOSRA scales, attitude toward inquiry and career interest in science, have a small but significant influence on students' achievement in chemistry. This study highlights the importance of examining if the scores apply similarly for different group of students in a population, since the scores on these assessments could be used to make decisions that will affect student. The research studies presented in this work are a step forward with our intention to understand better the factors that can influence students' decisions to stay or leave STEM-related careers. Each study has provided psychometric evidence for the use of three different assessments in college chemistry courses. Instructors can use these assessments in large and small lecture classrooms. Information obtained from these assessments can then be used to make target interventions to help students learn and/or be more confident on a given task. Also, it highlights the importance to look at different group of students, such as the underrepresented groups, since response trends may be different. Being aware of students' diverse needs will help us to understand some of the challenges that student face in the chemistry classroom. Understanding some of these challenges will help instructors be more prepared for teaching.

This paper extends upon Jennifer Hunt’s research on “Why do women leave science and engineering?”, that contributes to existing literature that overlooks underrepresented minorities level of commitment to STEM fields based on their STEM educational backgrounds and additional contributing factors that relates to women engineer’s leaving their felid to another felid that does not have any relation to their STEM degree. The following independent factors are the respondents’ gender, reasons for leaving the felid of major, how much does their highest degree relate to their current principle/ primary job, parents’ level of education, current citizenship status, level of highest degrees obtained and salary survey data impact on exit rates of STEM identifying URMs. This is done by running multiple linear regression statistical analysis models by creating dummy variables for underrepresented ethnic/ racial minority grouped all together and isolated each URMs’ group dependent variable along with the contributing factors as my independent variables. In order, to figure out which factors are heavily correlated to the exit rates of URMs departing from STEM fields. In addition to learning more about the reasons behind the increasing exit rates of STEM identifying URMs, I will be discussing the shortcomings of using the 2015 National College Graduate Survey as my data and how the survey respondents’ level of exposure to STEM education from their primary school years suggests that the respondent is more likely to stay within a STEM felid that collates with their highest STEM degree than someone who has rarely been exposure to STEM education from youth.

This study investigated the academic self-efficacy and persistence goals of 72 diverse female Engineering majors. Social Cognitive Career Theory (Lent, Brown, & Hackett, 1994) coupled with Practice Theory (Bourdieu, 1998) and Social Capital Theory (Lin, 1999) served as the theoretical framework. The relationships between social cognitive variables (engineering self-efficacy, outcome expectations, interests) as well as the influence of contextual and cultural variables (perceived campus climate, distance from privilege, and access to resources) on female students' intent to persist in Engineering were examined. Hierarchical linear regression revealed that only outcome expectations significantly contributed to the prediction of female students' intent to persist in Engineering. Exploratory analysis revealed that outcome expectations were most influential in predicting Engineering self-efficacy. Including privilege and perception of campus climate into the model significantly predicted self-efficacy above and beyond the original SCCT variables. This study supports the addition of cultural contextual variables in the SCCT choice model and warrants future research with minority female populations. Key words: women in STEM, social cognitive career theory, privilege, persistence, underrepresented students

The purpose of this qualitative study was to explore pre-medical advisors’ perceptions on their role in the pathway to medicine for students historically underrepresented in medicine (URiM) and to gain insight into barriers these students face. While a small amount of research exists on the perspective of URiM pre-medical students on the pathway to medicine, no analysis has been conducted on the role pre-medical advisors play. The underlying framework of this research study focused on the experience of advisors through the lens of academic advising approaches, self-authorship theory, and capital theory to make a strong collective framework to begin understanding the role of advising in the pathway. Data were gathered through interviews using a non-random purposeful sampling strategy. Study participants were pre-medical advisors at undergraduate institutions in the SAAHP. Participants discussed their role in the pre-medical pathway for URiM students, advising approaches they employ, and their advising experience. Key themes emerged during data analysis. Advisors tend to approach their student encounters as individual experiences but draw from a variety of advising approaches. URiM students experiences a variety of barriers but most frequently encounter financial barriers, academic challenges, and concerns over lack of belonging. Advisors face a variety of challenges in addressing barriers faced by URiM students. Advisors indicated that early intervention for academic support, collaboration with others tangential to the process, and more visibility for URiM students were approaches that would help retain URiM students on the path to medicine. There is perceived value in utilizing the role of pre-medical advisors as a method of support to keep URiM students moving forward as they can both an advocate for their success and help them navigate the challenge of being a pre-medical student.

Student retention rates and graduation rates currently play a major role in measuring the success of institutions of higher education. To contribute to the likelihood of this success many institutions offer programs designed to increase the academic performance of their students especially those classified as incoming freshmen. Others are more focused and target those who are from underrepresented populations. Nonetheless not many programs have been designed to aid those students in the subsequent years that follow freshman year. The purpose of this research project was to determine if there are significant differences in the success of those students who participate in a multi-year program as opposed to those who participate in a program specifically designed for incoming freshmen. Additionally these 2 groups were compared with students who did not participate in either program. The participants in this study were classified within 3 groups: Quest for Success, Student Support Services, and nonprogram participants. Archival data were used to examine grade point averages, retention rates, and graduation rates. A random sample of 125 students from each of the 3 groups (375 total) was examined for the purposes of comparing mean grade point averages. For the purposes of comparing retention rates and graduation rates, however, the population was examined due to the manner in which data were provided. Additionally the use of the population provided more precise retention rates and graduation rates in this study. Findings of the study are congruent with the literature in terms of the role that outreach programs play in the success of underrepresented students. These results revealed that students in the multi-year program, Student Support Services, had significantly higher grade point averages, retention rates, and graduation rates when compared to Quest for Success (a 1-year incoming freshman program). Student Support Services also had significantly higher grade point averages and retention rates than nonprogram participants from underrepresented student populations. Furthermore there were no significant differences found in comparisons between Quest for Success and nonprogram participants.
