Badges in Moodle
Teachers can add and manage badges in their course by following the link in Administration > Course administration > Badges. Moodle will automatically resize new badges to the appropriate 90 pixels square. A variety of designs are available for download at http://moodlebadges.com.
Students can publish any or all of their badges at Mozilla's Open Backpack after completing the Preferences > Backpack Settings found in the upper right-hand corner of a Moodle page.
A student can view other students' course badges by going to Navigation > Participants and clicking on the course profile of a chosen user. Badges are visible in the short (course) profile.
