  Vidcast:  https://youtu.be/Co-zziI5pmw   Learning comprehension and retention are unaffected by watching an instructional video at up to twice the speed.  Educational psychologists at UCLA studied this phenomenon in 231 of their undergrads by having them watch two 15 minute videos including one about the Roman Empire and the other about real estate appraisals.  Groups screened the videos at either normal speed, 1.5 times faster, 2 times faster, or 2.5 times faster.   The participants were tested immediately after each viewing and again a week later.  Comprehension and retention were statistically identical between normal and double speed but declined with viewing at 2.5 times the normal speed.   So students……If you’re short on time, and who isn’t, ramp up the playback speed and rest assured that you’re not missing much.  Modern digital players adjust the audio pitch so your professors don’t sound like the Chipmunks.   https://www.sciencedaily.com/releases/2022/01/220111153637.htm   #education #speedlearnin
