Hey Pam,
You and I are exactly alike whenever it comes to admitting mistakes. I simply own up to the mistake and move forward. Students give you the utmost respect whenever you can admit you made a mistake. Afterall, as you have said we are only human. We are far from being perfect. I tell my students exactly as you do, if I don't know a response to a question, I let my students know immediately that I do not know, but I will have an answer for them the next day. Although we are educators, students understand that we don't know every thing.
