I would apologize to my students if what I taught was wrong. In fact, I even apologized if I was unable to attend their class. I believed in earning respect, one should apologized if errors/mistakes occur and that's include teachers, too. In that way, students have high respect for their teachers and teachers should also respect their students too. But I agreed with mesmark that sometimes a teacher should not proceed if he/she is not sure of something.
