Exploration Of Privilege And Preschool Teachers’ Demographics Associated With Teachers’ Self-Efficacy In Culturally Responsive Classroom Management, Katherine Madison

Electronic Theses and Dissertations

Every child in America is entitled to a free public education; however, racial disparities in academics and discipline continue to grow in America’s school system (Glock et al., 2019; Muñiz, 2019). These racial disparities begin in preschool, following the students throughout their school years. African American students, specifically African American males, are three times more likely than their Caucasian peers to be suspended in preschool (CRDC, 2016; Musu-Gillette et al., 2016). Suspension at an early age correlates with students entering juvenile detentions, prisons and incompletion of schooling (Love, 2014; Meek & Gilliam,2016; Muñiz, 2019). Culturally responsive teaching and classroom management …

Music With A Racial Nexus: Culture Clash In Los Angeles Punk Rock Communities, 1976-1981, Lawson Hammock

Electronic Theses and Dissertations

The chief argument of this work rests on the idea that culture-blindness—especially White ethnic-cultural blindness—contributed as much as issues of race to the heavily documented social rift between predominantly Chicanx, Eastside punk and the mostly-White, Westside punk rock communities of Los Angeles, 1976-1981. To date, historical blame for the divide has centered on racism, including racist intent. The second area of analysis directly relates to the first in that it demonstrates the inextricable link between cultural and spatial identity formation and assignment among the various scenes. This aspect of the study evaluates the complaints of some Eastside acts who have …
