Teamsketch is a collaborative drawing app for iPads that allows multiple users to sketch simultaneously. It was developed to support collaborative learning in educational settings. A field study with 16 elementary school students used Teamsketch in small groups. The study found that Teamsketch enabled all students to see and contribute to the shared sketch at once, though some groups struggled with the interface. Overall, Teamsketch showed potential for collaborative learning but also opportunities for interface improvements.

5. Implementing mobile devices in
teaching and learning settings:
• Beaming of stored information
• Location awareness
• Portable sound- and voice-recording
• Cameras for taking photos and
making video clips
• Connectivity for spontaneous
communication and collaboration
amongst learners
Kukulska-Hulme & Traxler, 2005

6. Learning theories:
• Location based Learning: Real life
situations
• Social Learning: Learning is an active part
on the learners themselve and occurs
through participation
• Game-based Learning
• Collaborative Learning
Sandra Schön et al, 2010

20. Discussion
• Each pupil can draw on every part of the sketch
simultaneously
• Every pupil can see the whole sketch at a time
• Some difficulties with the user interface
• Groups need a significant amount of time until they
were able to draw together
