Every spring, REACT Fellows who will be doing research at GIANT for the upcoming summer present teaching talks that serve as the foci for a REACT-Center for Teaching and Learning (CTL) workshop. Presenters get specific feedback on their presentations from the audience; the audience engages in a broader discussion of STEM pedagogy, led by CTL’s Julie McGurk. This year, we had a record number of student and faculty participants, making for a rich session on April 8, 2019.
