Email - as a source. So look back at your email. What names do you see coming up? Perhaps reach out to someone that you see listed frequently. Or, do you feel one of your classes has transitioned well? Reach out to that faculty member and get their thoughts on how they undertook the transition.
This video, while doing an interview about a specific event, provides many useful interviewing tips.
General tips when you interview:
1. Avoid Yes/No questions. Focus on Who, What, Where, When, and Why. "Do you like Columbus?" isn't a very useful question - it isn't well thought out (they are part of the community after all) and it is a closed question. "What are your thoughts about Columbus?" gives more room for the person to answer.
2. Prepare your questions ahead of time, even if you know the person. This helps you avoid closed questions and helps you focus one what you really want to ask.
3. Avoid compound questions. For example, "What do you think about the travel ban and how this impacts your family" These are two separate questions.
4. Watch for your own assumptions. Don't let your own ideas lead your questions. "Parents that don't vaccinate their children should be punished, right?" shapes the interview in a direction that may not really show the beliefs of the person being interviewed.
