I don't know the book.
What I do know from personal experience with many students  is that quite a
few seem to graps the idea of an ADT, but fail to realize how to create
layered designs, and modularize their programs.
I always try to show examples like building set ADT from a list package,
using various layering techniques (composition, using inheritance etc.).
