Wow- Nichole, what an interesting experience you and Becca had.  I'm wondering what your colleagues think about this?  I agree that things were wrong with the experience you observed. Sometimes the folks we work alongside do not share our definition of literacy or learning... Sometimes parents don't share our definitions, either.  Remember your locus of control.  While you may not be able to control what happens when your students are away from your room, you can control the experience they have in your room, and whether or not they have additional trips to the library where you are supervising. Just thoughts for the future.
