I had one of my worst teaching classes ever today. It was a misunderstanding, not really a matter of "fault," but frustrating anyway.
I tried to make do by using the media available in the room, a computer, projection system, etc. Unfortunately, the sound didn't work, so my attempt failed, frustratingly for all of us. You know, chalk has never failed me. Computerized classrooms fail me at least once a term.
Someday, this will be funny. Now, I'm just tired. Three down, twelve to go.
I have to finish reading for tomorrow, in hopes that things will go better.
