Hi Dave! Thanks for pointing me in the direction of this post. I want to start by saying that giving Oscar the medium to showcase his expertise was a smart way to encourage him to continue his process of inquiry into a subject he was/is passionate about. That is powerful stuff when a parent is able to provide that type of environment in the home. On the other hand, when you mention the faults of your good intentions, it should be a reminder that teaching is a deeply reflective practice. I would argue that there is no perfect lesson. That with some critical reflection, we could have always done something better. That is part of the challenge of teaching. I appreciate your honesty in pointing out ways in which you could improve upon your questioning to open his mind and extend the inquiry even further. I think you have showcased some valuable learning, both from Oscar and from yourself.
