Here's a quick snippet of what Carol L. Tilley, professor of library and information science at Illinois says about using texts and tweets in lessons:
"There's always that danger when embracing something in a school setting that you kill it for the students," Tilley said. "But helping kids understand the social and contextual role that texting plays in their lives I think is one possible justification. If there are ways educators can incorporate it in providing homework support or building dialogue out of school hours, then I think it could be a useful communications tool."
