van Zee, Emily; Gire, Elizabeth; Hahn, Kelby T.; Belden, Mackenzie – Journal of College Science Teaching, 2022
Sessions of our laboratory-based physics course have been "meeting" synchronously online instead of on campus due to the pandemic. Shifting to remote instruction prompted us to create online versions of the course. In the unit on global climate change, for example, we continued engaging students in documenting their initial and evolving…
