For both students and especially for teachers, one of the most helpful aspects of Khan Academy is the activity logging: we record when you do videos, exercises, and challenges, and surface that on user profiles, progress viewer, and teacher reports.
After launching the DonorsChoose rewards program a few weeks ago, we got a lot of reports from teachers anxious that they couldn't see the fact that their students had watched the programming videos- that's because the programming "videos" are actually "talk-throughs", these crazy things we invented that sync audio to coding. But, hey, that shouldn't matter, we should still be logging the talk-through watching the same way we log the Youtube video watching everywhere else on the site. We want programming teachers to know as much about their students' progress as math teachers, to have a consistent, great experience.
As of today, we are now logging talk-through progress the same way that we log video progress. You'll see them show up in the activity feed, progress reports, weekly emails, activity graph - anywhere you see videos now:
We hope this helps teachers track their students better, and we look forward to continuing to improve the teacher experience. If you ever have feedback, feel free to comment here or email us at compsci-feedback at khanacademy.org.
