![]() This morning, I completed the program, which, for anyone tracking Khan Academy points, is just shy of 2 million points. And, with the exception of one five-day block, I was successful in that goal, doing math on 151 out of 156 days. My goal was to do some math every day until I completed the entire program. ![]() On November 15th, I decided to do the Khan Academy "World of Math", which at the time comprised around 1090 sections, ranging from basic math to differential equations. Nevertheless, I did find that there were a number of areas that either I had forgotten, or never found important enough to commit to memory. I went to a good high school, where I got (mostly) As, and then went to Princeton University to study computer science. I was inspired, and I realized that like everyone else, I had holes in my understanding as well.Īs far as background goes, I had a pretty solid mathematics background. For subjects that build on past mastery, you really have to get it all right, and continue to build a solid foundation for future learning. Of course, some of those holes do fill in through the practice of later problems, but his point is still clear. But what happens to those parts you got wrong? There’s no process to go back and fill in those holes, and they just accumulate. He said that when you’re in school, you study for a test, and maybe you get a good score. In the interview, Khan talked about the “holes” in education. ![]() I had been familiar with Khan Academy, as my son had used it on a few occasions. In November 2015, I saw an interview with Sal Khan on CNBC.
