This paper systematically analyzes and optimizes teaching strategies for private university teachers through the lens of Behavioral Science theory. The introduction explores the role and function of private universities in the higher education system, highlighting key issues in current teaching strategies. The literature review examines domestic and international research progress on teaching strategies in private universities, outlining the application of Behavioral Science theories to teaching. The research design and methodology section present the research model, hypotheses, sample selection, data collection, and analysis methods. Based on surveys, interviews, and classroom observations, the status analysis section investigates teaching design, classroom organization, and teacher-student interactions, identifying existing problems and challenges. The study proposes multidimensional optimization strategies grounded in Behavioral Science theory, emphasizing individual behavioral incentives, group behavior management, and organizational culture shaping, with a strong focus on digital teaching platforms. The conclusion summarizes the main findings, discusses research limitations, suggests future directions, and highlights practical insights for university administrators, frontline teachers, and policymakers.
