When we pulled ds out of the middle of 3rd grade, he was like this. (Well, except that he did like to be read to.)
He did not want to read to himself and absolutely refused to read anything aloud. It took a very, very long time for him to deschool. I was really concerned at first, and would cringe whenever I heard him say, "I hate reading." I'm a real bookworm myself and as it turned out, his younger sister (who learned to read on her own rather than in school) was reading tons more and quickly passed him up as far as reading ability went. I was very concerned that he'd never be a reader.
I made myself notice though, when he WAS reading--the video games he liked at that time required a lot of reading, and while he sometimes needed help with it, his motivation was high and eventually, I noticed that he'd stopped asking me, "What's this word?" so much. When the tv was on, I'd put the closed captioning on, figuring it couldn't hurt. He liked the internet and of course, needed to read there. We'd play board games that required reading.
Most important of all though, was that I not make an issue of the reading. I didn't point out that he was reading, or even tell him that he was doing a good job. If his sister was around, I had to be very careful that he wasn't in a position to be "outdone" by her because he was very self-conscious about the fact that she was such a fluent reader.
He did like to be read to, and sometimes I'd do the reading and sometimes I'd just put a tape into the player and we'd go about our day. But I really believe that forcing the issue could backfire and he could end up hating reading for good. I mean, he had been forced to read in school and look where he was.
He did like comic books, so I made sure there were plenty of these around. I think at first he was just looking at the pictures, but then after a while he'd talk about the story line, so it became evident that he was reading them. He also read catalogues--he's always been really into Legos and would pour over the catalogue when it arrived. And he liked magazines and the Eyewitness books (they're heavy on photos with small captions--much easier for a struggling reader to take on than a page full of text.) After some time of just this type of reading, he discovered the "Bionicle" series of books--hardly great literature, and a very easy beginning chapter book, but it was a book, and he was very interested in it. I couldn't believe that he was doing this voluntarily, but finally, it had happened. He read the whole series and moved on to other books.
He recently read a fantasy/fiction book about dragons/knights (I can't remember the title) but it was a very thick book and I was shocked that the size of it didn't deter him. But he read it and loved it and came and told me a lot about it. He doesn't read nearly as much as his sister does, and he still prefers to listen to books read aloud, and hates to read aloud himself, but he reads and understands what he's read, and enjoys it. That he find enjoyment in reading was my #1 concern.
If you really are intent on forcing the read aloud time, maybe you could negotiate the amount of time with him? Maybe cut it to 10 min. at first? Or ask him what he thinks is a reasonable amount of time? Or just agree to stop reading when he's had enough? (It might be 5 min. one day and 30 the next.) I don't think you're going to get anywhere if he's focused on counting the minutes until you stop reading, yk? Repeatedly being forced to do something one hates doesn't usually result in one learning to love the activity.
