On YouthVoices.live they've completed a similar task: They've looked at 10 posts selected by me and then skimmed the site for posts that interest them. On that youth focused network they've also hunted for claims, finding and considering evidence all the while gauging their own interests.
The formal arguments they've written and submitted support claims of a different sort, though. Their papers have been informational and personal and don't argue against counterclaims. After reading Sherman Alexie's "Superman and Me," and studying the TED talk "Danger of a Single Story," by Chimamanda Ngozi Adichi, I asked the sleepy juniors in #english11, 7:30 AM at Rangeview High School, to draw conclusions about an author's view of literacy and then to make a claim about how that author's view compares to theirs about books, stories, literacy and stereotypes.
