Knowledge is an important predictor and outcome of learning and development. Its measurement is challenged by the fact that knowledge can be integrated and homogeneous, or fragmented and heterogeneous, which can change through learning. These characteristics of knowledge are at odds with current standards for test development, demanding a high…

In this study, we identified the specific discipline decision situations (i.e., vulnerable decision points [VDPs]) that contribute most to racial discipline disparities from a sample of 2020 schools across the United States. We also examined how much VDPs contributed to overall discipline disparities and the extent which there was similarity among…

Two set of studies were conducted to better understand grades and grading practices in physics courses, and how these might influence demographic representational disparities in physics. The first study investigates the relationships between grades and the student-level factors of standardized test scores, (binary) gender, underrepresented…

This research is comprised of a three-part examination of equity, access, achievement, and learning in precollege physics. The first study examined teacher-level and school-level predictors of student performance in physics, with a focus on isolated teachers in New York during the 2016-17 academic year. Results indicated 40% of physics teachers…

This article examines whether age, work-related, and family-related predictors explain differences in the academic advancement of women and men in Iceland. Survey data were analyzed by binary logistic regression. The findings put that women climb the academic career ladder at a slower pace than men. This finding puts one of the widely known…

The aim of the current study was to examine mean-group differences on behavior rating scales and variables that may predict such differences. Sixty-five teachers completed the Clinical Assessment of Behavior-Teacher Form (CAB-T) for a sample of 982 students. Four outcome variables from the CAB-T were assessed. Hierarchical linear modeling was used…

The present study addresses women's underrepresentation in the academic profession, as well as the need for policies and practices aimed at this issue. It compares underrepresentation of academic women in North American countries, and explores, throughout a bivariate analysis, personal, professional, as well as institutional variables related to…

Research has widely documented the over-representation of office disciplinary referrals (ODRs) among specific student groups (e.g., African American, boys). Despite extant research documenting individual-level predictors of ODRs, few studies have accounted for the nested structure of the settings in which these events occur. Guided by critical…

During the latter half of the twentieth century, Australia, like many countries in the Organisation for Economic Cooperation and Development, experienced rapid expansion in participation in higher education which was supported by government through increases in the number of publicly funded university places. However, in spite of this expansion, a…

The purpose of this dissertation research study was to investigate engineers' perceptions of diversity and the workplace learning environment surrounding diversity education efforts in engineering occupations. The study made use of a mixed methods methodology and was theoretically framed using a critical feminist adult education lens and…

This quantitative quasi experimental study compared and analyzed African American/black, Hispanic/Latino, and Caucasian/white American students' selection to enter a certificate, technical, or transferable degree program at a community college. This study explored the relationship between students' race/ethnicity and the students'…

The researcher investigated three types of factors, academic, commitment, and social on college sophomore's decisions to persist at predominately White institutions. The academic factors (academic integration, academic rigor), commitment (goal commitment and institutional commitment) and social factors (social integration and racial climate) were…

This research project investigated the possibility of School-Wide Positive Behavior Support (SWPBS) as a way to address racial/ethnic disproportionality in the Emotional Disturbance (ED) category. The sample consisted of 114 elementary schools from a suburban school district in the Mid-Atlantic region. There were 57 SWPBS schools and 57 non-SWPBS…

Although it is well established that Black male students are underrepresented in gifted educational programs in the United States, due to a scarcity of longitudinal prospective research, little is known about the protective factors at the child, family, and school level that increase the probability of Black male students being identified as…
