Item FORMATIVE-HOME CULTURAL INFLUENCES OF SCIENTIFIC SENSE-MAKING: A CASE STUDY ON THE AFFORDANCES OF PEDAGOGICAL “BIO MECHANISTIC THOROUGHNESS” (“BMT”)(2020) Powell, Kweli Bennett; Chazan, Daniel; Elby, Andrew; Curriculum and Instruction; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Science education research continues to struggle with clarifying the formative-home culturally pedagogical merits of everyday, vs formal science vocabulary focused, classroom discourse (ex. Hammer, et al, 2005; Warren et al, 2001). More broadly, cross-contextual cultural pedagogical efficacy is a resonant aim for education scholar-practitioners in general, regardless of topic (ex. Chazan, 2000; Howard, et al, 2017). While a bio-mechanically thorough (BMT) methodological lens could offer robust theoretical insight into these questions, such an application has yet to become widely evident. In this dissertation, I apply a bio-experimental theoretically based case study approach (Yin, 1989) to interrogate the BMT-causal African-American cultural dynamics of two science sense-making transcripts. The first transcript (2010) featured a first year cohort of teachers as they engaged in the same science sense-making discourse that we researcher-trainers aimed for them elicit in their classrooms. Findings indicate that, from a BMT-aligned perspective, the learning practices of the two African-American (formative-home) cultural participants (out of 5), indeed evinced signatures of their formative-home culture’s discursive-behavioral influence. The second transcript (2012) featured a first year cohort of teachers as they engaged in a facilitated science sense-making structure identical to that applied in 2010. Again, BMT-informed findings indicate that the learning practices of the three African-American participants (out of 6) showed signatures of said culture’s motivating impact. Further notably, relative to the first (2010) context, the 2012 cohort evinced markedly more on-topic discursive-learning per unit time. This dissertation models the affordances of a BMT-aligned case study lens (Yin, 1989) for understanding the culturally causal dynamics of productive sense-making. Results suggest that the distinction between the two transcript outcomes rooted in a deeper sense of ‘starting familiarity' or 'communalism' amongst the focal cultural participants in the 2012 group, a factor shown to uniquely resonate among African-American learners (ex. Boykin, 1994; Seiler, 2001). These findings demonstrate how science sense-making educational contexts that cultivate 'everyday', thus including formative-home culturally rooted, discourse can facilitate learning. This model can inform the development of cross-contextually robust forums for sense-making based teacher-preparatory policy, regardless of topic.Item The Perceived Undergraduate Classroom Experiences of African-American Women in Science, Technology, Engineering, and Mathematics (STEM)(2013) Holmes, Kimberly Monique; Fries-Britt, Sharon L.; Education Policy, and Leadership; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The purpose of this dissertation study was to explore African-American women's perceptions of undergraduate STEM classroom experiences, and the ways in which those experiences have supported or hindered their persistence in physics majors. The major research question guiding this study was: How do African-American women perceive the climate and interactions with peers and faculty in undergraduate STEM classrooms? Using qualitative methods and a multiple case study design, a sample of 11 women were interviewed. This study was also informed by data from 31 African-American women who participated in focus group interviews at annual meetings of the National Society of Black and Hispanic Physicists. Findings indicated that the women excelled in small courses with faculty who took a personal interest in their success. They also perceived that there was a pervasive culture in physics and other STEM departments that often conflicted with their own worldviews. Findings also indicated that the women's perceptions of classroom experiences varied widely depending on professors' behaviors, institution types, and the level of courses. It is anticipated that through a better understanding of their perceptions of STEM learning environments and factors in their persistence, STEM faculty and departments can better retain and support this population of students.Item The Relationships between High School Sports Participation, High School Completion, and College Enrollment for African-American Males(2009) Harris, Paul Christopher; Lee, Courtland; Counseling and Personnel Services; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The purpose of this study is to explore the direct, indirect, and total effects of high school sports participation on high school completion and college enrollment for African-American males using a large, nationally representative, longitudinal database (ELS:2002). The lens through which this phenomenon is viewed in this study is the sports-impedes-mobility hypothesis (Braddock, 1981). A path analysis procedure for determining underlying causal relationships between variables was presented for six different sports participation models. The only sports participation variable to have a significant effect on either high school completion or college attendance was that of junior varsity sports participation significantly influencing (totally) high school completion and (indirectly) college attendance for African-American males. The effect was positive. While the implications of the results of this study are relevant for all who work with this population, school counselors are specifically highlighted.
