This is ClassMetric’s “post-lecture view” for a June 29th lecture at UC Berkeley.

What happened during lecture?During a lecture it’s incredibly difficult to keep a mental record of what’s working well and what’s throwing students off - professors are focused on teaching! ClassMetric can give some insight: our post-lecture view combines student understanding and questions to reveal exactly where students got lost.
Once these points of confusion have been identified, professors and TAs can easily prepare for recitations, send out additional material to the class, or design appropriate homework, tests and projects. We hope that by quickly identifying where students need help we can save professors and TAs tons of time.
The Post-Lecture ViewLet’s take the post-lecture views from above and see how they can be helpful.
The plots on the left of each image show student understanding and confusion over time: green is understanding, red is confusion. By dragging the blue slider, the professors and TAs can quickly relive the lecture, with student questions sliding into place along the right-hand side.
What did students understand? (top picture)All we need to do is move the slider to the peak of greatest understanding! From the questions we can see that when the professor was discussing SubVersioN (SVN), everyone understood him!
What did students find confusing? (bottom picture)Just move the slider to the point of most confusion. Using the questions as a guide it’s clear that students found method overloading to be quite confusing.
Now the professor and TAs can regroup, offer alternate explanations or assign specific homework questions to ensure that students really learn method overloading.
Ilya and Peter used ClassMetric to present to MIT’s 6.976 Founder’s Journey last week - we’ll be sharing our post-lecture view soon!If you have some ideas about how to improve the post-lecture view or just think it’s cool, we’d love to hear from you!
