Digital Badges are useful in adult education to reflect participation in online training programs.
The purpose of the badges is to allow the participant in the course to have an indicator of what they have taken, imply what else they can do, and can document achievement on their resume or CV as to what classes they have taken. For the participants they have pride in their efforts to learn as reflected by the badge. Badges can be printed and framed and hung on their wall.
