Citizen science projects have gained momentum in recent years and involved members of the public in ongoing scientific research. Nationally, there are an estimated 8,500 volunteers monitoring U.S. water bodies and 26 states sponsoring volunteer monitoring programs (Overdevest, Orr & Stepenuck, 2004). In Oklahoma, water quality data is collected by volunteers of Blue Thumb (BT), a state-wide program emphasizing stream protection through education and involvement of the community in monitoring local water-bodies. As the first phase of a multi-phase evaluation design, the goal of this research is to map the experiential education processes and learning outcomes of the BT program. A mixed methods research design guides this programmatic review of BT and the guiding questions for the study: (1) What attributes and processes of experiential learning are found in the Blue Thumb programs?, (2) What are the measured and intended participant learning outcomes?, and (3) How do Blue Thumb educators employ experiential pedagogies to achieve these learning outcomes? The study employed an explanatory sequential mixed methods design, with qualitative data being used to add contextual understanding to the quantitative data.
