Khan academy

I tried to watch the video that was posted but after about a minute and a half the video stops. I started to do my own research on this topic and found that the Khan Academy now has an app for the iPad. This is the link about the app and the consumer reviews. I was able to locate this video which is the same but has a different title.

Khan academy started about 5 years ago when Khan started tutoring his cousins. He decided to upload some videos onto youtube. His cousins told Khan they liked him better on youtube. Now his cousins were able to pause, rewind and go back to relearn a topic. At the same time other people began stumbling on his videos. People began to respond to his teaching and appreciating what Khan was putting out there. And so the Khan Academy was born. Now, classrooms are being flipped, lectures were watched at home and homework was done in class. 

The Khan Academy wants students to reach mastery. Each time a student masters a topic, they are moved on and up. This is an amazing free tool that makes diagnostic simple. Teachers are able to see EXACTLY what students are struggling with, where they paused the video and where they stopped watching. I will be passing this along to the girl I am tutoring.
