With Liz Fosslien
I made a confusion button
, which allows students to anonymously signal when they're confused in lecture. The lecturer page shows how many people press the button every 30 seconds. If you're curious to try this out in your class, email me and I'll be happy to set it up for you.
Also with Liz
I made this transcription tool
, meant to help journalists and qualitative researchers transcribe the audio from interviews. I can personalize the controls for you if it's useful.
