This document summarizes an experiment using wikis with English language learners in Japan. Pairs of students were asked to create wiki pages using information from a provided source, with one student working at the keyboard while the other provided feedback. Issues that arose included a general lack of computer skills, unease with unstructured tasks, and difficulties with wiki interface elements like creating and recognizing links. The document concludes that wikis have potential for collaboration and knowledge building but require support from teachers to help students structure information and learn wiki functionality.
