Weinburgh, Molly H.2025-12-042025-12-042025-12-01https://repository.tcu.edu/handle/116099117/67434This dissertation explores how science education influences environmental stewardship through the City of Dallas’ Branch Out Dallas tree giveaway program (2019-2024). Using a mixed-methods case study, participant survey data were analyzed to assess tree care knowledge, stewardship intentions, perceptions of program effectiveness, and tree mortality outcomes. Results showed strong engagement in basic care practices and increased learning, but they also identified gaps in long-term maintenance knowledge, which contributed to higher mortality among certain tree species. Qualitative findings emphasized the importance of accessibility, bilingual resources, and experiential learning. Grounded in constructivist learning and environmental stewardship theories, this research demonstrates that urban reforestation programs enhance civic engagement, promote environmental awareness, and strengthen urban forest resilience through education and participation.Format: OnlineenScience educationUrban forestryEnvironmental stewardshipExperiential learningText
