Scientific Thinking and Exploratory Discussion Posts

Abstract

Discussion posts have been used to involve students in a greater understanding of class material, particularly in applying it to the world outside the classroom. For online classes, they often serve as the primary channel through which students communicate with each other. We can also use discussion posts to facilitate scientific thinking and analysis by having students explore a question or problem, research it to find sources, and interpret results. These range from watching an educational video and describing the host’s analysis and results for a particular experiment, to doing their own search on everyday phenomena like static electricity in laundry, power generation on a Washington wind farm, or lightning. These types of weekly discussion posts have been added to both my Introductory Physics and Astronomy classes, and student engagement and reaction has been overwhelmingly positive.
