This is an example where a simple idea can truly change the world. In 2004, a man from Louisiana named Salaman Khan took the math lessons he had been giving to his cousin and began hosting them on YouTube. The lessons are simple. Most are 10 minutes long and consist of a person drawing or writing the lesson while conversing with the listener. The overall effect is like looking over someone’s shoulder while they do a math problem. This expanded into a massive collection of online lessons in science and technology and has grown into the Khan Academy, a website where thousands of lessons are available for viewing. There are also self-directed assessments. Funded by such notables as Google and Bill Gates, the website contains lessons in everything from adding to advanced calculus, all of it available for free. Teachers are even able to set up online “classrooms” where they can assign these virtual lessons to students and monitor progress.
Currently there are 2,100 mini-lectures and over 100 exercises that have been viewed by over 46 million people, providing educational lessons from first grade through college. As part of the effort to make it available to everyone, the lessons have been downloaded onto disks and distributed to impoverished nations without internet access.
I see using this for my advanced math students who need something extra. This site, along with a loose framework of assessment should give them plenty to do. Go ahead and give it a look, its great stuff.
