Like all the books I'm reading for my graduate degree there was some great stuff, but I've talked about it so much that I don't feel like writing about it.
The book does a nice job of defining and explaining what is meant by a curriculum, how the ideas and development have changed over the years, and where education is going.
(For instance, when people talk about "the curriculum" they could mean the lessons themselves, the material for the lessons, the unit, the subject, the order, any mix of those, and a number of lesser esoteric meanings as well. Fun stuff.)
