abstract: Teachers use different rates of positive feedback with students who are high-risk for emotional and behavioral disorders (EBD) in comparison to the rates of positive feedback teachers' use with low-risk students. By addressing the differential treatment, it may alleviate some of the related negative effects students high-risk for EBD experience, such as poor educational and social outcomes. The study explored the extent of teachers' differential use of feedback toward students identified as high-risk and low-risk for EBD. The data were collected in 56 teachers' classrooms by measuring rates of feedback delivered to 1 high-risk and 1 low-risk student per classroom (112 students total). Results revealed that teachers used positive strategies infrequently with the students high- risk for EBD. Results further indicated that teachers were over reliant upon using negative feedback with high-risk students. Descriptive variables within the study, such as school-wide and teachers' self-evaluations of positive classroom strategies, schools' special education population, and suspension rates were further explored. Implications for professional practice and potential future lines of inquiry on the differential treatment of students at risk for EBD in educational settings are presented. / Dissertation/Thesis / Ph.D. Special Education 2011
