I think this poll is mostly meaningless, and I'll get to why at the end of this long post.
Teaching is hard. It's always struck me as bizarre and stupid that every one of us gets 4 years of science-heavy yet well-rounded undergraduate education, 4 years of science-only medical school, and 4 years of internship/residency, before we're expected to effectively teach.
You can't get a job as a substitute teacher at a junior high school without SOME kind of teaching credentials. Not necessarily a master's degree in education, but SOMETHING that involved being explicitly taught how to teach. My son just finished his sophomore year of college. He's a music major, plan A is to be a rock star, plan B is to be a high school music teacher, so he's on a track that will lead to teaching credentials. He's already had more hours of education instruction and OJT/internship teaching than I've had in my entire career. He'll probably end up going to grad school for more of it before going to work as a teacher.
Physicians generally have no formal training on education theory, how to evaluate people, how to give feedback, how to remediate people who are struggling, etc. It's no wonder that teaching during residency is so hit or miss. Where I am now, a couple times a year our affiliated university comes through with a day or two of seminars on how to teach. These are very good but they're a band-aid for what's really a huge hole in our training.
Everyone at this level really needs to have figured out the "adult lifelong learner" thing, and should be getting 90%+ of their foundation facts on their own. That doesn't mean that one-on-one teaching in the OR should NEVER be about the differences between type 1 2 and 3 protamine reactions, but ideally we aren't using that time to present facts.
When I think back to the best teachers I had as a resident, I'd say that the best ones didn't spend a lot of time giving me information. Rather, they were excellent clinicians with good judgment who corrected my plans when they had to (with reasoned explanations) and let me execute an OK plan when it was safe to do so, and then smirked as I struggled. I felt secure that they could bail me out of trouble I or the surgeon caused (within reason). I could ask questions and get answers that were better than appeals to habit or dogma.
Residency is more apprenticeship than traditional didactic education. I'm not sure I even agree that residents need "teachers" so much as role models and someone skilled to help them get the work done. I don't think this is something that can be assessed by quantifying the number of minutes spent "teaching" in the OR. I didn't vote in the poll because I honestly don't remember how often or how long my attendings gave me "teaching" in the OR.
