Classroom of the future by Bill Gates.

According to Microsoft Chairman Bill Gates, if you fast-forward a decade, classrooms and lessons might look a little different.

Today, classes are too big. Lessons are taught the same way to dozens or hundreds of students -- each of whom has different learning style. Technology can, and should, change that, Gates argues.

"Being there physically doesn't add much value," he said. He believes the days of big lectures with hundreds of students gathering in university classrooms may be numbered. Gates envisions a college of the future in which students watch lessons online, delivered by the brightest minds in the field.

"If you want the very best lectures, if you want the cost efficiency, you have to break down and say, 'you know, let's take someone else's material," Gates said. With the money saved from hiring professors, resources could be poured into labs and study groups. Gates' idea is one of many visions for the quickly transforming education system in the world.
