Some of the novels I've read as an adult I would have liked to have seen on our school curriculum. Examples are 1984 by Orwell and Northern Lights (Golden Compass) by Phillip Pullman. I think novels with a controversial element are far more likely to encourage students.
We didn't have summer reading lists, and the only required reading were exam texts. At GCSE (or end of high school exams) we studied the Child in Time by Ian McEwan, which at the time was one of the most dire books I had ever read. I have since come to appreciate it, although I still don't enjoy it. We studied the Crucible by Arthur Miller, and Macbeth.
To be honest though, a lot of the problems with those classes were the two teachers I had. Neither could control the class, and subsequently not a whole lot of learning was done. We were then of course ill-prepared for our exams.
Terrible at most other subjects, I was lucky that English has always been my strong point, and luckily I sailed through the exams with no notes, my poetry anthology had been destroyed by another student, so all my margin marks were no longer in existence. We had done no revision, had been taught no exam technique, no mock papers, nothing.
The majority of lesson time was spent watching the tutors trying to convince the boys to take the classroom furniture off of the roof and put it back in the classroom.
Our A level years though were much more organised. And the tutors actually cared about our results. Particularly our Eng Lit teacher. When we studied Chaucer, all discussions took place in Olde English dialect.
When we studied Othello she took us to a play to help us appreciate Shakespeare as it was meant to be - on stage.
We weren't given reading lists per se, but I asked for suggested reading for novels, plays, poetry and so on, and she sat down for what must have been quite a while, and penned me a comprehensive list.
I don't think it's the reading material that influences our education so much as the attitude of the teachers.
And just for the record, that comprehensive list lit the way to Stoppard, Osborne, Heller, Orwell, Poe, Austen, DH Lawrence, and many others I would have missed out on had she not been there to guide me.
