Duncan Seraphin, Kanesa; Harrison, George M.; Philippoff, Joanna; Brandon, Paul R.; Nguyen, Thanh Truc T.; Lawton, Brian E.; Vallin, Lisa M. – Journal of Research in Science Teaching, 2017
We present an inquiry-based, aquatic science professional development (PD) for upper-elementary, middle, and high school teachers and examine changes in student outcomes in light of participating teachers' characteristics and the grade band of the students. Our study lends support to the assertion that inquiry- and content-focused PD, paired with…
