Mr. Khan calls his collection of videos "Khan Academy," and he lists himself as founder and faculty. That means he teaches every subject, and he has produced 1,400 lectures since he started in 2006. Now he records one to five lectures per day.
He started with subject matter he knows best—math and engineering, which he studied as an undergraduate at MIT. But lately he has added history lectures about the French Revolution and biology lectures on "Embryonic Stem Cells" and "Introduction to Cellular Respiration."
His site is here.
The best part about Khan Academy is, that courses are well-designed, and most if not all instructors seem genuinely engaged and concerned with the outcome of the learning process. Courses are organized thoughtfully, with content presented in a logical manner. I've "taken" a variety of courses through Khan Academy, ranging from the hard sciences to business development. And when I was in college, I used the site to help re-explain some math concepts.
ReplyDeleteI used to find the errors in the math videos, and many of them appeared to be more "seat of the pants" rather than organized and thought-out. Many of these videos are being re-done and are much more professional.
ReplyDeleteI used Khan Academy for a couple lessons in linear algebra about 8 years ago!
