To let you know where I'm coming from, I'm a homeschool parent, I studied literature in college, and I'm a writer. And this book made me want to run headfirst into the nearest wall.
The Goldstones' premise is that when an author writes a book, they start out by thinking of some moral lesson they want to impart, then create a plot around it. If kids are trained like dogs to sniff out the protagonist, antagonist, setting, climax, and other stuff that makes me sleepy, they can then peel all that away to find this object lesson. Or something.
As a writer, let me tell you that this is crap. Books are not a mystery with a single correct answer tucked away inside for children to find like the prize in a Crackerjack box. They're stories. Messy works of word art that mirror life and make us feel things. All the things, if a book is particularly good.
Sure, they'd be much easier to teach if, like the Goldstones claim, you could sort them neatly into checklists using supposed clues left by the author and then find the shining, perfect moral in the middle, but they just don't work like that. And no, I won't be shutting down my daughter's questions about her books if they "lead to dead ends or superficial observations" that don't "make steady identifiable progress," like they advise. The idea makes me feel vaguely ill, in fact. I also won't be following their advice to never let my daughter read books that aren't really hard and don't provide fertile ground for handy charts. I mean, heaven forbid she enjoy a good story without having to come up with "insights about character, plot, and even the author's motives." And let me tell you, no one can know the author's motives. Half the time, even the author has no idea. Stories that are created because the author had some kind of motive to teach kids a lesson usually suck. If I want someone to beat me over the head with morality about something or other for several hours, I'll call my mother.
Also, for some sick reason the authors feel the need to give away the ending of every book they discuss, so if you haven't read one of them yet, skip that section.
