Most teaching days are what I would label “adequate.” They’re not spectacular, they’re not horrible, they’re just fine. Other days are great- days when you can tell the students are really connecting with what you’re saying and you know you’re presenting it well. Then, you have the other days. The lousy teaching days when things just don’t seem to come out right. And it doesn’t matter how many times you’ve presented a particular lecture- every so often, you’re just going to be terrible.
Today I had my first Bad Teaching Day of the semester. I came, I saw, I really, really blew. At least now I can stop worrying about it.
