  1. Week 6 Video 2 Visualization Moment-By-Moment Learning Graphs

  2. First… • I’d like to start with an observation about learning curves

  3. They shouldn’t be called learning curves

  4. They should be called performance curves

  5. They should be called performance curves • Because they show the relationship between performance and time • You can infer learning from them… • But they aren’t curves of learning

  6. This was fine for decades… • Until folks actually wanted to graph learning over time • Then it became really annoying

  7. Moment-By-Moment Learning Graphs(MBMLG) • (True learning curves, but we can’t call them that)

  8. Based on theMoment-By-Moment Learning Model • Baker, R.S.J.d., Goldstein, A.B., Heffernan, N.T. (2011) Detecting Learning Moment-by-Moment. International Journal of Artificial Intelligence in Education, 21 (1-2), 5-25. • Discussed in mathematical detail in week 4

  9. Moment-By-Moment Learning Model • Gives us moment-by-moment assessments of learning

  10. Can be used to create aMoment-by-Moment Learning Curve • X axis: Opportunity to practice skill • Y axis: Moment-by-Moment learning assessments

  11. Moment-by-moment learning curves • Are meaningful to interpret for individual students • Much harder to do this with traditional learning curves • Accuracy = 0 or 1 • Time is noisy

  12. Let’s look at a few graphs

  27. Multiple skills treated as a single skill

  28. Corresponds to (several)

  31. It’s still a mystery to me…(post your ideas on the forums!)

  32. (It turns out to be quite common)

  33. Uses • To study relationships between learning trajectories and learning outcomes • Baker, R.S.J.d., Hershkovitz, A., Rossi, L.M., Goldstein, A.B., Gowda, S.M. (in press) Predicting Robust Learning With the Visual Form of the Moment-by-Moment Learning Curve. To appear in the Journal of the Learning Sciences.

  34. Uses • To analyze individual students’ learning

  35. Uses • To study which learning material most promotes learning • Gowda, S., Pardos, Z., Baker, R.S.J.d. (2012) Content Learning Analysis Using the Moment-By-Moment Learning Detector. Proceedings of the International Conference on Intelligent Tutoring Systems, 434-443.

  36. Next lecture • Heat Maps, Scatterplots, and Parameter Space Maps
