OK, Shannon, here is my case study.
Case study #1
Situation: Young girl lives in a home devoid of books, but full to the brim of movies and flat screen TVs. The shelves in her room are filled with VHS tapes by the time she's ready to start school. She has this aunt who can't stand the thought of a child growing up without trips to the library, and books to fill her imagination. So the niece gets books every birthday and Christmas, and sometimes in between. The niece and her aunt go to the library together often, and the niece learns the joys of the look-up computer, the nice librarians, exploring her passions, and checking out the same books over and over. Then the young girl hits fourth grade, and her school uses Accelerated Reader. Reading is for tests and points, nothing is read that doesn't "count," library visits fall off. The birthday books this year were CHASING VERMEER and THE FAIRY TALE DETECTIVES. On a recent road trip, niece and aunt listened to the audio version of CHASING VERMEER for about 10 minutes, and then the niece was fast asleep.
Result: Final outcome for niece: unknown. Current status of the aunt: I'm not going to quit trying.
(And just FYI, no link will be provided for Accelerated Reader. If you want to go there and find out what they think they are and what they think they do, you can type it in your browser yourself.)
(OOOoooh. I think we hit a nerve!)
