Sero! Closed

Automated, xAPI-compliant, browser-based concept map learning assessments.


Sero! uses browser-based concept maps, a diagramming technique for representing, assessing, and transferring knowledge, into the context of the Total Learning Architecture (TLA), informing the maturation of the “learning ecosystem” concept. This effort is developing the Sero! tool, a prototype web-based software package providing automated support for the process of assessing learners' mental models using concept mapping. Sero! is now a mature, open-source software tool, that supports xAPI and learner/assessor feedback and implements reporting capabilities.

Major Deliverables

  • System Requirements, Use Cases & Design Documents
  • Sero! participation in TLA development and experimentation
  • xAPI-compliant Sero! v1.0 open-source software
