What do you do when you don't know what to do?
I advise students to "ask questions and don't stay stuck."
Sometimes I fear that some educators or students who don't know what to do choose inaction instead. For example recently a volunteer offered an educational service to a colleague. The colleague asked for the necessary tools to make this happen, and was met with a lack of a response. Hence, the volunteer has not received a response and a good idea waits.
Sometimes even if you don't know what to do, it's best to communicate the fact that you don't know and the steps you are taking to find out and respond.
Learning streams become more fluent and responsive when everyone involved responds to questions, rather than choose not to respond because they "don't know."
