Beyond Diversity Initiatives: Building A Community Of Care In Scientific Societies, Richelle L. Tanner, Kathryn Wilsterman

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

"In this Professional Biologist article, we present one such reframing that centers individualized care through structural changes. We argue that psychological and sociological motivations of belonging and social capital in the academy are funda- mental challenges contributing to the cultural problems within STEM fields and are particularly present within professional scientific societies. In support of this argument, we present survey- based data alongside significant literature from the humanities. In this reframing supported by existing organizational culture literature and our survey results, we suggest that scientific societies are uniquely positioned to promote significant cultural change within STEM by focusing on building …

Predicting Secondary Mathematics-For-Teaching Knowledge Using Beliefs, Experience, And School Culture: A Hierarchical Regression Analysis, Adam R. Brulhardt

Theses and Dissertations

Research in recent decades has supported the notion that practice-based mathematical knowledge is crucial for effective teaching, playing an important role in enacting reform-oriented instruction required for improving student achievement. Despite its importance, teachers—especially novices—require more support in acquiring such knowledge, an ongoing challenge exacerbated by teacher shortages. The purpose of this quantitative study was to determine whether collaborative school culture (CSC) explained variance in knowledge of algebra for teaching (KAT) beyond variance explained by mathematics-related beliefs and years of teaching experience for U.S. secondary teachers. Measures within an online Qualtrics survey included the Beliefs About Mathematics and Teaching Scale …
