Multi-touch surfaces have the potential to change the nature of computer-supported collaborative learning, allowing more equitable access to shared digital content.

Analyzes the interaction during peer response occurring in a writing class. The article identifies four categories of reader stances--authoritative, interpretive, probing, and collaborative--and examines language functions and topics discussed during the response sessions. It is concluded that interactive peer response is beneficial to students.…

Investigates the sincerity and validity of uptake as a measure of language learning by comparing the words students report they have learned after completing a listening task with the words they score correctly on a translation test. Results indicate that whereas uptake may have construct validity, its concurrent validity is uncertain. (16…
