Survey of 20 streaming videos which demonstrate expert practice, trying to distill common patterns. No interviews with creators or viewers. Supervised by Philip Guo.

They note a few patterns of interest which seem to reflect elements of Cognitive apprenticeship at scale:

  • improvised solutions to unexpected problems
  • improvised examples adding depth to explanation
  • explanatory tangents inspired by workflow
  • pausing for high-level advice or commiseration

And a few barriers of Tacit knowledge:

  • pattern irreducibility: impulses that resist reduction to rules / generalization
  • context dependence: overwhelming contingency
  • routinization: emphasis on practice, automaticity, unconscious action

{instructional workflow} stream: streams which demonstrate “{naturalistic workflow with the intent of teaching skills to others}” ☉

{serendipitous teachable moments} in streams: {improvised content which might not normally appear in a tutorial video but which provides value by emulating what would happen in cognitive apprenticeship} ☉
