Khan Academy offers two things: A “free, adaptive math program” and over 800 how-to videos on almost any math concept you can think of.
About the math program: Our children are doing the math program this year and really prefer it over our past method of using a textbook math program. Khan Academy’s program “learns” how much you know after a couple hours of working on it. Soon, it will have you up to the math level you should be on, and with the aid of the videos, you can keep learning math concepts, building on your knowledge.
About the professor (the following text is taken from the Khan Academy website) :
Salman Khan (Sal) founded the Khan Academy with the hope of using technology to foster new learning models. He is currently an investment professional in Palo Alto, CA and has held positions in venture capital, product management, and engineering. Sal received his MBA from Harvard Business School. He also holds a Masters in electrical engineering and computer science, a BS in electrical engineering and computer science, and a BS in mathematics from the Massachusetts Institute of Technology.
Many testimonials are posted on the Khan Academy site, including these:
“I am a high school Math/Physics Teacher working in Toronto Ontario. I have been referring students to your videos for the past year and have referenced many of them on my website. Those that have used it find it very useful, and have commented that you explain content better than I do…”
“…Your videos have become very popular in my school, and my grades have sky-rocketed ever since I became accustomed to your methods of teaching...”
“I’ve never been very successful with algebra, I know this is pretty basic, but I have almost no comprehension of mathematics. I was honestly going to be kicked out of school for being non-productive, I was ready to be thrown out, but now I get this. Thank you so much…”
Linda Barger, who emailed me about Khan Academy said her son “loves the site.” Thank you, Linda, for this high quality, 100% free, educational find!
