Dissertations and Theses @ UNI

Creating and maintaining a positive school environment is critical for fostering academic achievement, social-emotional development, and the well-being of students and staff. Research consistently demonstrates that a positive school climate enhances student engagement, reduces disciplinary issues, and improves teacher satisfaction and retention (Brookover et al., 1979; Cohen et al., 2009; Thapa et al., 2013). Effective school climates are characterized by safe, supportive, and inclusive environments that encourage collaboration and mutual respect among all members of the school community (National School Climate Center, 2020).

Black Girls In School: The Harmful Effects Of Dehumanization And Disciplinary Inequities, Annika Peterson

Graduate Research Papers

Black girls in the U.S. experience dehumanization through adultification and sexual objectification that impact disciplinary practices in the education system. Adultification stereotypes Black girls as more mature, less innocent, and less in need of protection, which results in harsher disciplinary actions and limited empathy from educators. At the same time, sexual objectification reinforces harmful perceptions of Black girls' sexuality and culpability in their sexual violence victimization. The “Jezebel” and “Angry Black Woman” stereotypes continue to influence how Black girls are perceived as either hypersexual or aggressive. These biases and stereotypes contribute to disproportionate disciplinary measures, particularly subjective infractions like “defiance” …
