Status: Requirements Needed

User Story

As a learning science researcher, I want to analyze the latency values using the performance profiler so that I can potentially do a number of things, among them: - See what the average correct, error, and total step time is for a full unit of a course, for a section, or for a KC. This would allow me to test claims of the PSLC Theory Framework about differences in complexity of KCs (as reflected in the Correct step time) and about complexity of instructional events (as reflected in the error step time). - Use to in KC model search, like error rate, to see for instance whether any step instances of a KC really stand out from others with either unusually long or unusually short times. --Koedinger 11:46, 2 April 2010 (EDT)


  • Add Assistance Time and Correct Step Time to y-axis options. -- Ken Koedinger, Mtg with Connie, 8/13/2008
  • Revising for DataShop v3.5.7. Now using the word "duration" instead of "time", so the request should be: Add Step Duration, Correct Step Duration and Error Step Duration to the y-axis options. -- Alida, 9/3/2009
  • Here's a simple feature request that would be very useful and, it would seem, relatively easy: Add the timing variables (Correct Step, Error Step, and Step Time) as possible variables to display (on the top) in the performance profiler. This fix would probably make it into my top three. -- Ken Koedinger, Email, 3/26/2010
