The role of the teacher in reading comprehension is interesting to me. It made a lot of sense, but it was good to have it explained outright: that a teacher in a child's younger years has to give a much more complete scaffolding of how to extract meaning from language. The main thing I got from exploring this concept was just wonder at how children come into the world needing to learn EVERYTHING, even things that, to us as adults, seem so natural and obvious. Sorry if that's a bit esoteric, but I can't get over it. It is something to be cognizant of as we interact with young learners.
