How are the Jem and Scout's perception of things changing?

Jem: Jem is starting through puberty from somewhere around the middle of the novel. So his view on things like playing is that it is childish, and he starts to want privacy and his innocence is fading. Scout: Since Aunt Alexandria came along she's been being taught to act like a little lady, so she's steadily becoming one as the story progresses. She's been growing up mature-ways too, she stops believing in childish rumors and her tomboyness fades, and she learns how some people, even though they've never done anything wrong, will be hated for no reason.
