I was thinking that if I had to look up words in a dictionary, I'd play dumb too. LOL Isn't there a more fun way to improve her vocabulary? Games? Learning roots? figuring out roots from context? I guess I wouldn't judge her attitude toward learning based on one assignment that doesn't sound like much fun. Maybe the tutor could come up with something more playful to start and then as she got hooked, give her something more challenging.
