How often have you heard the phrase "this will change the way we learn"? 

As this episode of Veritasium explains, first it was the motion picture that was going to change the way we all learned, by showing us the things our teachers were talking about. And next it was radio and TV that promised to get rid of local teachers and allow all students to learn from one centralised expert.

And now, the Internet and educational YouTube videos are being heralded as the technologies that will transform classrooms forever.

But while all of these advancements have clearly revolutionised other areas of society - entertainment, for example - the truth is that we pretty much learn in the same way we did a century ago.

And Derek Muller from Veritasium believes that it won't change anytime soon. Why? Because the real limit to learning is the stuff that happens inside a student's head. That's where the real revolution needs to happen, but we still don't know much about what goes on in there.

Derek explains that although there's plenty of research into which types of technology are more effective, there's very little work being done on which experiences and technologies promote the thinking required for learning.

And the research that's out there shows that learning is socially motivated, which isn't something we can replicate through better technology - yet, anyway.

So what does Derek believe is the real key to helping us all learn more effectively? Watch the episode above to find out.
