Open edX Content Tagging

• edX Adaptive WG (2016)

  • Flexibility - Abstracting out the taxonomy concept as a separate authorable entity in the platform

    • Common Core high school algebra
    • Khan’s Knowledge Map
    • Metacademy
  • Versioning - taxonomies change over time
  • Multi-alignment - multiple taxonomies associated with a single course/library
  • Portability - transport across MOOC instances
• Content Tagging (2017)
  • Product memo with incremental needs based on Credo's work
• Open Learning Initiative @ Stanford Semantic Tagging requirements (2014)

  • Learning objective = what student will be able to do by the end of the module

  • Learning objective contains skills (sub-objectives)

  • Skill = discrete concept or knowledge component, actionable for instructors

  • OLI courses have 30-50 learning objectives and 100-1,000 skills

  • Tags to associate with course resources in a many-to-many relationship
  • Categories of tags
  • Tags and categories have names and descriptions
  • Tags not in tracking events, but sent with course exports
• Content Tagging (2014)
  • Use cases
    • OLI's learning objectives and skills
    • MIT's Backstage with learning objective graph and relationships
    • Content library filtering
    • Adaptive
  • xBlock Asides proposed in contrast to Stanford's generic framework
