Are all my badges tiered?
No not all my badges or tiered. I do believe some of my arrangements are a star or a network. I do think badge organization should follow the organization of the knowledge domain. I do think it would be more of a network of related subjects, skills, events... that as they are earned would form clusters or groupings. I organized as a tiered approach for I was wanting to relate the categorization like the color scheme of the martial arts belt system.
I do believe the work Mozilla has been doing around badge system design is excellent and I believe they are wanting to stay away from the tiered or hierarchical approach. But I do think many humans organize in hierarchies...
|Mozilla Webmaker is also becoming the exemplary badge system design. Kudo's for creating a great example!
Do I create a table for all my badges, or just tiered badges?
No, I don't create a table for all my badge systems. I do believe it is important to provide some way to organize, display and describe the badge system. A table is one way... and due to my using wikiversity for the mobile app dev course, the table seemed like the best way to go.
Do I have a giant table for all badges in one course?
I don't see creating one giant table to describe all the badges. There does need to be some way of describing the badge system as a whole. I believe it would help people understand the learning pathways within the badge system if there was a "curriculum" or "learning journey" map. I do see that Mozilla Webmaker is doing great work here as an example. See Erin Knights post; http://erinknight.com/post/29830945702/webmaker-badges
I also see the badge system and approach created by the Khan academy is also an interesting example of displaying a whole badge system.
