The “Khan Academy” has received worldwide recognition since it was created three years ago, when Salman Khan began producing instructional videos for his niece. Since then, it’s become a cultural phenomenon, as thousands of people are now using the videos for a source of free education. There are hundreds of videos available on the site, covering topics from basic algebra to complicated computer science.
While this seems like it can’t possibly be a bad thing, some teachers are warning that Khan’s videos could actually be potentially harmful for students. They believe that the “lecture” learning process could actually inhibit learning, since it doesn’t allow for hands-on interaction.
Maybe it’s just me, but most of my high school (and college) classes didn’t really involve a lot of “hands-on” activities. Perhaps these teachers are just feeling anxious that a society based on free education could put them out of a job?
