April 5, 2021

“Chunking” is a term coined by psychologist George Miller to describe our short-term memory’s ability to hold and process information. This video provides an introduction.

Please add your own ideas for chunking and/or video presentation to the Open Space doc.

  • Studies suggest our short-term memory can hold an average of four chunks of information at once.

Ideas for video presentations: 

  • Include a rundown of topics at the start of the video
    • Add timestamps in the video description if possible
  • In addition to chunking your topics, consider chunking the video itself: 
    • Add digital transitions if you know how (if you have a Mac, iMovie makes this easy)
    • Break up the lecture-nature of the video with:
      • Stretch breaks
      • Hidden information
      • Scene changes
      • Moments where your face is not on screen
      • Audio/visual surprises/disruptions (change volume level or appearance, add a dramatic pause, emphasize words, task challenges, Easter eggs, etc.) 
  • Use hand gestures and facial expressions to make the visual aspect of your video more engaging
  • Shorter is better – if you have to make a long video, add disruptions.
  • Remember, you don’t need to fill all your class time with a video. Consider Open Educational Resources (pre-existing videos, podcasts, etc.), reflection questions, task challenges, discussion, etc.
