Salman Khan and the Khan Academy are back in the news, having recently being featured on NPR and PBS. At the Khan Academy website, there are more than 1,100 free instructional videos, each 10-20 minutes long, that range from basic arithmetic and algebra to differential equations, physics, chemistry, biology, and finance. The videos cover concepts that, as a student, Sal felt were poorly taught through lectures and textbooks. Each video explains the concepts covered in the lesson in a comfortable, relaxed manner that reflects Sal's own easy understanding of math and doesn't compromise rigor or comprehensiveness. Sal also has included several hundred videos devoted to the SAT, GMAT, and other standardized test problems.
Since I first wrote about the Khan Academy back in December 2008, Sal decided to quit his day job and devote himself full-time to expanding his library of instructional videos. Eventually, he plans to add even more academic subjects to the website.
The videos at the Khan Academy website can be used by a wide variety of students, including:
-
students who need a bit more instruction to understand a concept,
-
those who want to learn beyond what is being taught in the classroom, and
-
students who are preparing for certain standardized tests such as AP, SAT, and GMAT.
The videos can also be used in a variety of venues, such as the classroom, home, and around the world. Those who live in areas where an advanced class is not available, or those who are homeschooled, would particularly benefit from viewing Sal's videos.
I highly recommend that you take a good look at the website. View some of the instructional videos yourself and take a look at some of the videos explaining more about Sal Khan and his plans for the Khan Academy. The website is a wonderful resource and it is free.
