Collaboration One to three students per tablet Interaction between students often encouraged Instructors would survey and occasionally comment on student work during activity phase Student work a key part of classroom discussion March 19, 2007 Asia-Pacific Regional Workshop on Mobile Computing in Education 30
31
Anonymity Work displayed on public display without any identification Limited information about submission displayed on the instructor machine Anonymous display valued by the students Students often believe the instructor can identify their work Tagging behavior observed March 19, 2007 Asia-Pacific Regional Workshop on Mobile Computing in Education 31
