Philosophiae Doctor - PhD / The U.S. has a problem: it is not effectively utilizing all the bright young minds available to its science & engineering workforce. In 2012 the President’s Council of Advisors on Science and Technology (PCAST) reported that a million more STEM professionals in the U.S. workforce were needed over the next decade. PCAST reported that the situation is far worse for underrepresented students, who make up 70% of undergraduate students but only 45% of the STEM degrees. Recent reports suggest women in science and engineering have made small gains, while historically underrepresented ethnic groups (Blacks, Hispanics, American Indians) continue to be significantly underrepresented. The lack of diversity in the U.S. workforce is not reflected in the USA population nor is it reflected in the undergraduate student population. As the U.S. aspires to retain a leadership role in research and development in an increasingly diverse and globally interconnected society, this disparity is unsustainable. What if having more culturally interesting, more culturally responsive STEM classes is a way of increasing the diversity of the science and engineering workforce in the U.S.? This study focuses on a topic that has been generally overlooked by the STEM educational community, but one that is directly relevant to student engagement and learning outcomes: the role of culture as a variable in student learning. This study examines how different pedagogical approaches shape student outcomes in Astronomy 101 courses. In a comparative study two different pedagogical approaches were analyzed using both quantitative and qualitative methods in a semiexperimental nonequivalent group research design. The theories of culturally responsive pedagogy (CRP), active learning theory in STEM, and Indigenous knowledge systems (IKS) ground this approach. The findings of this study show important gains for all students. Underrepresented minority students (URM) in the course with increased culturally responsive pedagogy were exceptionally engaged and learning gains soared. By measure of the concept inventory, the URM students in the course with increased culturally responsive pedagogy outperformed all other students in the study. As the U.S. will have a non-white majority by the year 2045 and diversity in STEM faculty lags there is a need for tangible, evidence-based, culture-based curriculum and pedagogy. There is a problem and based on the evidence found in this study, there is a way to fix it. / The U.S. has a problem: it is not effectively utilizing all the bright young minds available to its science & engineering workforce.

Employee Training and Development (T&D) is a crucial component to an organization’s success and its ability to remain competitive. Although researchers in the field have discovered ways to enhance the effectiveness of training programs through the design, delivery, and evaluation process, research has not provided empirically-based recommendations for how to best train individuals whose cultural backgrounds may influence receptiveness of training curriculum. This is particularly relevant for employees whose cultural groups have been historically discriminated against, where cultural norms implicit in the training design may be met with resistance on behalf of the trainees. In the field of multicultural education, an instructional approach has been suggested to overcome cultural differences between instructor, curriculum writers, and students known as culturally responsive education. I evaluated a pre-training video prime based on this approach in the context of multi-site data-use training program for Native American educational professionals. Data-use training was delivered after exposure to one of two videos that framed the objectives of data use either in a culturally responsive way or in a generic mainstream fashion. Participants filled out surveys after the video but before the training, and then again after the training. Prime type was randomly assigned by training location. I hypothesized that participants who received a culturally responsive training prime would learn more during the data-usage training than participants who did not, and that this effect would be mediated by heightened affective motivators immediately following the culturally responsive prime. None of the hypothesized pathways were supported. There was no direct effect of my prime manipulation on knowledge (Hypothesis 1) or skill acquisition (H2), or on pre-training motivation to learn (H3), research-related self-efficacy (H4), goal-commitment (H5), or identification with research (H6). Furthermore, there were no indirect effects of my manipulation on knowledge (H7) or skill (H8) acquisition through pre-training motivation to learn, self-efficacy, goal-commitment, or identification with research. The motivation to learn subscale for valence had a significant positive direct effect on knowledge and skill acquisition and self-efficacy significantly positively predicted skill acquisition. Goal-commitment and motivation to learn subscales for instrumentality and expectancy had a significant negative relationship with skill acquisition. Lack of support for my hypothesized pathways is explained partially by the failure of my independent variable to influence perceptions of cultural responsiveness. A manipulation check revealed that participants did not appraise my culturally responsive priming video as significantly more relevant or culturally appropriate compared to the alternative mainstream video. Findings on the positive effects of valence and self-efficacy are discussed in support of current literature. Negative effects of expectancy are discussed in terms of stereotype threat. The implications and applications for trainers and researchers in training and minority education are followed by a consideration of this study’s limitations and suggestions for future research.

The study of culturally relevant pedagogy (CRP) within a social and emotional learning (SEL) program is timely as it supports the increasing body of literature on narrowing the educational gaps prevalent among Black students. Current research is lacking regarding if and how educators utilize CRP to support the learning of SEL competencies with Black students. For this study, the tenets of cultural relevance, SEL competencies, and the leadership practices of one urban district seeking to increase its overall accountability rating as deemed by the state of Texas were examined. The purpose of this study was to determine the adequacy of the district's response to the needs of Black students in terms of cultural relevance when selecting a SEL program and developing a support plan for the program's implementation at the campus level. A secondary purpose was to examine the extent to which the district embedded CRP practices into their adopted SEL program. A qualitative exploratory research design and case study research approach were utilized. Documents related to the SEL program chosen by the district were analyzed. In addition, semi-structured interviews with district leaders and a focus group with campus administrators were conducted. It was found that there were no direct actions by the district toward ensuring that district's SEL program was culturally relevant nor was there support provided to ensure that SEL was implemented in a way that would be meaningful to Black students. Implications for future practice, recommendations for future research, and a researcher reflection serve as the conclusion.

Children from many culturally diverse backgrounds do not achieve in mathematics at the same rates as their counterparts from the dominant White, European-American culture (Gay, 2010). This so-called achievement gap is an artifact of an educational system that continues to fail to provide equal learning opportunities to culturally diverse children (Ladson-Billings, 2006; Nieto & Bode, 2011). Teachers who employ culturally responsive teaching (Gay, 2010) may help to close this opportunity gap and hence, the achievement gap. This study investigated, "How do elementary teacher candidates perceive teaching mathematics in a multicultural environment"; Using a critical constructivism research paradigm, this qualitative instrumental multiple case study involved a questionnaire, two interviews and a focus group with four elementary teacher candidates enrolled in a one-year teaching licensure program. The study examined elementary teacher candidates' images of mathematics and diverse students and the relationship between those images and their perceptions of teaching mathematics in a multicultural environment. The study concluded that the participants', images of mathematics, learners, and the teaching of mathematics were interrelated. The participants struggled to understand how students' diversity based on group membership (e.g., culture) influences a mathematics classroom and their teaching. However, on the basis of these participants, teacher candidates who hold a conceptual image of mathematics could be more open to adopting culturally responsive teaching than teacher candidates who hold a procedural image of mathematics. The study recommends the integration and modeling of culturally responsive teaching throughout all teacher education coursework.
