I have recently received three separate emails from folk who are raving about Brian Frank’s Desmos card sorts for teaching introductory mechanics (Physics 1) and the remainder of the introductory course (Physics 2). These are excellent resources for use in online instruction, particularly in individual instruction (Desmos is really intended as individual instruction and has a nice teacher proctoring interface), or to inspire and drive small group or whole classroom discourse, and I plan to use them myself. Thank you and kudos to Mr. Frank.
Bree Barnett Dreyfus recently tweeted about using “StickMan Physics,” which presents a nice collection of compelling, simple animated GIFs and MP4s useful for slides and online teaching.
