As part of the Broader Impacts portion of our project, PI Vaughn and grad assistants DuBose (OU) and Hopper (KSU) partnered with the University of Oklahoma K20 Center to provide an “Authentic Research Experience for Teachers”. This 5-day workshop for secondary science teachers (grades 6 – 12) was held June 12 – 16, 2017 at the Kiamichi Forest Research Center in southeastern Oklahoma. This Center is near several of the field sites used in our research. Eleven middle and high school teachers from across the state of Oklahoma participated and were provided lodging, meals, travel reimbursement, and a monetary stipend with funds from the grant. The workshop focused on the important functions and ecosystem services provided by rivers. Teachers spent the morning in the field working alongside the scientists. Teachers learned how to measure and describe physical and chemical characteristics of streams, sample and identify macroinvertebrates, and sample and identify freshwater mussels and fish. Teachers performed experiments in the field where they measured the filtration, excretion and respiration rates of mussels. In the afternoons, science curriculum specialists helped the teachers develop and translate their field activities into classroom ready learning experiences for their students. Feedback from the workshop was very enthusiastic and some teachers have remained in contact with us. Graduate student Popejoy has been helping one of the teachers whose school is nearby (Noble High School) with their curriculum, has loaned him equipment and supplies, and has guest taught his class.
