The first time I heard about Khan Academy was in the PIDP course. I was amazed by its broad spectrum free educational service for students all over the world. This non-profit organization provides micro lectures and educational tools for educators.
I can remember my PIDP classmates sharing stories about students who used Khan Academy and how they became very successful in the subject matter.
I would like to share this video by Salmon Khan, the Founder of Khan Academy, talking about “Let’s use video to reinvent education.”
