Learning Glass

The Learning Glass is a tool for student engagement for both face-to-face and online classes. The Learning Glass is a transparent “whiteboard” where professors write with a neon marker facing the student. This setup allows for freehand writing and diagramming without having to turn one's back to the audience. This technology is especially valuable for instructors of science, math, or engineering, who often work through formulae or explain complex processes using illustrations.

How does the Learning Glass work?  The Learning Glass has an LED light on a low-iron glass which creates a transparent whiteboard. Using neon markers, the presenter faces the camera while writing on the Learning Glass. Images are flipped in post-production.

Best Practices

1. Preparation

When using the Learning Glass for the first time, you'll have the opportunity to rehearse and get to know the various technologies involved.

  • Script your video out in advance, either using bullet points in an outline or word-for-word.
  • Rehearse on your own before using the Learning Glass.
  • Consider how to efficiently use space;  Learning Glass has smaller surface area than a whiteboard.
  • Formulate visual aids ahead of time.
  • Wardrobe:
    • Wear dark blue colored clothing with long sleeves for best visibility of text.
    • Avoid logos or text on clothing as it will appear reversed in post-production.
    • Don't wear checkered patterns or tight design shirts as moiré patterns may appear.

2. While Teaching

An instructor uses the learning glass

  • Consider the idea of one topic, per one board;  if you can fit on the board, then you can fit it in a single video.
  • Consider splitting up the videos into shorter takes if your presentation is longer than 8 minutes.
  • Speak clearly and enthusiastically.
  • Bring your notes to the recording session. You may also use a computer while using the Learning Glass if desired.
  • Start writing from the right or left side; don’t start writing in the center.
  • Avoid writing in front of your face. 
  • Once the Learning Glass is filled with notes, stop recording, erase the board, and restart the recording.
  • Don't worry about making mistakes or having a perfect recording; foibles or inconsequential mistakes are humanizing. Rehearse before the recording to reduce errors.
