After beginning to consider topics to research, things that wouldn't normally be noticed are strongly apparent. For example, I currently wonder about the benefits of a set routine. I now pay attention to how the students react when something "out of the plan" occurs and how smoothly things go when nothing pops up. What I noticed even more is the struggle that faces the teacher when something like that comes up. Just as students do, instructors benefit from knowing what to expect. When the unexpected arrives, dealing with it isn't always simple.
It would seem that one of the major goals of inquiry as teachers-to-be is to wonder about something that will influence our teaching behaviors (and therefore student learning). It would seem that point can't be reached, though without studying the behaviors of others. Through which, we learn about our own practices and passions.
