Road Map I. Wikis A. Collaborative Website B. Advantages II. Problem A. Text-Only Wiki Sprawl III. Study IV. Findings V. Follow-Up
Wiki – Definition an “interactive website where… webpages are editable by …users.” (Wagner & Prasarnphanich, 2007)
Example- Wikipedia.org
Contrast with Web Master Limited number of Editors The Gate Keeper Slow Change Changed Website Webmaster Client Desires User Complaints

But Input is a Problem
As is Navigation Wikis are Text- Based
The Wiki Learning Curve 1% of users make 50% of pages Wikipedia Founders Worried about Turning off new contributors
Study 9 month examination of the evolution of graphics within a student-driven wiki textbook
Participants N=21, students in 10 th and 11 th grades Latin courses at suburban Public High School Wiki-Textbook required
Navigation Menu: Month 1 Uniform Size Items Spatially Organizer for Outside Links Standard Approach to Wiki Navigation
Navigation Menu: Month 2 Menu Increases in Size Requires Scroll Items Uniform in Size Greater Number of Spatial Separators
Navigation Menu: Month 3 Number of Links continues to Increase Use of Non-Links as Organizers Users demonstrating better use of text tools
Navigation Menu: Month 7 Differing Size of Links Use of Non-Links as Organizers Menu cumbersome and too long
Navigation Menu: Month 8
Navigation Menu: Final
