I have just got a student who is quite an interesting case. Comes from a very musical family (dad is a producer and the CEO of a massive label and ridiculously good bass player, uncle is noted jazz player, brother is an awesome drummer). She is a classically trained pianist, flautist and classical-style guitarist but has decided to play bass (good girl). Her "issue" is that she can only play if the music is in front of her. She can't improvise or ad lib etc. She can play scales by wrote, but she doesn't really understand why the notes are related to each other. They want me to teach her how to play the instrument and understand it, and not use notation at all. She will be in good stead one day, as she will be able to do both, because her sight reading is excellent, but she will also be able to cope without the instructions in front of her. On a separate note, my sight reading is seriously poopieE. I got a gig singing tenor in a choir performing Elgar's Dream of Gerontious a couple of years ago, which was absolutely nails, but a helluva good kick up the arse to improve my sight singing.
