Greg Wilson uses video recording for feedback of his trainees. But, interestingly, not just for themselves to review.
Greg Wilson’s The Third Bit: Just Keep Swimming (Dec 2015)
When I do in-person instructor training for Software Carpentry, I have trainees film each other teaching short lessons. The main goal isn’t to give people feedback on their presentation skills: they could get that without being recorded. The real aim is to teach them how to scale their evaluations of themselves. Almost without exception, people will give themselves an F when others would give them a B; knowing that, they can adjust their self-assessment to be more accurate. And knowing that, they can start to improve.
