  1. Hi, Geoff – I have a question from our engineering design teacher. I sent your Retrospectus out to all our faculty and in reading it, she found Nguyen used as an adjective in several places. Can you tell me what it is in reference to? Thanks for your help!

  2. Oh, and you’re not currently a teacher, either, Geoff. Yet I would not rule you out as having useful things to say about technology in classrooms.
