1Cademy requires students to find the proper prerequisite node when proposing any new content summary.

University of Michigan - Ann Arbor

Throughout the semester, the 29 students collaborated to make 2,131 proposals for revisions to the map, improving the community's learning. This was accomplished through:
- The democratic peer review process
- The proposal mechanism
- The linking constraint

Asynchronous Collaborative Development

The # of net votes (upvotes minus downvotes) required to accept a proposal depends on how many previous net votes the corresponding node had.

Popularity-Dependent Acceptance Thresholds

Students can propose changes to the contents of nodes or links, and a review process determines whether the proposals will be accepted.
