A FAQ page might just be the answer.
- Create a blank page in your subject site, and link it from your navigation menu
- Add the most common questions that you can remember from last session, and their answers.
- As new questions come in this session, add them to the FAQ and let students know there have been updates.
- Repeat as necessary.
And yes, it’s that simple, and is guaranteed to save you lots of time at the start of session, and a lot of student angst!
