So what I'm suggesting is: take 200 students, and have 100 go through Khan's material, and 100 go through mine. Khan's kids would finish faster. Then, have all 200 kids attempt to code FizzBuzz on their own, with no assistance. I think probably 60-70% of my students could get it working. I suspect less than 20% of Khan's would have understood/retained enough to get it done. You are in the 20%, so it's hard for you to see the difference. Salman Khan is in the 1%, and he hasn't been in the trenches long enough to see the difference. That's what I'm saying.
