Student and Teacher Perceptions of the Impact Ethnic Studies Courses Have on Students of Color: A Collective Case Study

This qualitative research study explored student and teacher perceptions of the impact ethnic studies courses have on students of color. This study utilized conscientização or critical consciousness, authentic caring, and Critical Race Theory to understand teacher methods and strategies and the nature of instruction of ethnic studies curriculum in two urban public high schools in the Pacific Northwest. This research also examined how students perceived the curriculum and teaching strategies impacted their learning and engagement in the courses. Data collection included classroom observations, open-ended student survey, teacher and student interviews, and student work products. Data analysis included both inductive and deductive analysis. Inductive analysis revealed several themes about how teachers and students perceived ethnic studies curriculum and instruction including caring and creating classroom community, academic rigor, Critical Race Theory as a foundation for the course, discussion-based instruction, and de-centering Whiteness. Deductive analysis utilized pre-defined ethnic studies codes inspired from Sleeter’s (2014) work, including origin of knowledge, historical U.S. colonialism and contemporary colonialism, historical construction of race, and institutional racism. Results revealed that, overall, the ethnic studies courses had made a meaningful impact on student understanding of historical and contemporary issues affecting ethnic groups in their community. This research sought to learn from the experiences and perceptions of students of color in the ethnic studies courses. With the support of their ethnic studies teachers, students were able to engage in meaningful learning experiences that also impacted their educational aspirations. Students of color in the courses noted they have gained more confidence in how to navigate racism at their school and have a newfound courage to speak up against microaggressions and racial slurs. They felt that they had learned more in their ethnic studies class than they have before in other courses. The results and implications from this study are discussed and provide insight to educational practice and teacher preparation programs that better prepare teachers to meet the needs of all students

Prediction of Stage, Bathymetry, and Riparian Vegetation of the Lower Olentangy River After Removal of the Fifth Avenue Dam

The Olentangy River is a third order stream as it passes through urban Columbus, Ohio with an average flow of 191 ± 13 cfs and an annual peak flow of 2372 cfs (67.2 m3/sec). As it passes through the city, it is impounded by several low-head dams. The 2-mile reservoir created upstream of a dam (referred to as the Fifth Avenue Dam) on the river and adjacent to The Ohio State University campus is currently in non-attainment of biological and ambient water quality standards. Planned river ecosystem restoration of this pool is based on the removal of the Fifth Avenue Dam, which would increase stream velocity and sediment transport, improving total water quality. This study looks at the relationships among flow, stage level, and current bathymetry of the Olentangy River to predict the bathymetric profile of the river upstream of the dam after it has been decommissioned and the vegetation that will result on new riparian areas. The flow of the river was calculated as a function of the river stage using a rating curve developed by the U.S. Geological Survey for the Olentangy River Wetland Research Park (ORWRP) and previous research at the ORWRP. Using the relationship between river stage and flow, we predicted changes in the bathymetry of the Lower Olentangy River. Additionally, we predicted an increase of riparian vegetation by 47 acres (for an 80% drop in stage), with expected riparian vegetation based on the growth pattern of emergent vegetation at similar locations along the river and at the Olentangy River Wetland Research Park.Ohio Agricultural Research and Development CenterA two-year embargo was granted for this item
