5 Ways that edX could change education

Gaming is mentioned in this article as a way to teach labs online. I've heard that gaming is the future of education before. It makes sense because through gaming a student can learn a lot. they can find patterns and learn from their mistakes. (I'd like to do more research on gaming.) Mr. Agarwal a former director of MITs computer science and AI laboratory is working on creating a way to integrate gaming into the learning experience. "EdX's first crack at answering that question can be heard in the violins that filled Mr. Agarwal's office one recent morning. The music came from his computer, where he input it through a circuit. It's one part of a simulated lab environment that lets students rotate components and build circuits as if they were "assembling virtual Legos on a desktop," Mr. Agarwal says."
The people studying edX and trying to figure out how to make it work are not only trying to study the program but they are also looking a the human mind, how it works, and what methods are the best to teach it. The creators "view the project as a means to study even deeper problems, like understanding how people forget—and creating strategies to prevent it." How will edX be able to figure out answers to these questions? It's a pretty obvious answer actually. When edX becomes more widely known and excepted the enrollment of these classes is expected to reach the millions. Mr. Mitros the chief scientist of this project has says,"Basically, everything that a student does is logged and can be mined by researchers." All of the data being collected is already online, making it easier to study how people learn, and easy to make changes if necessary in  timely fashion. What Mr. Mitros wants to study is peoples memory, and how well they are retaining information. "To Mr. Mitros, most exciting is the chance for once-impossible cognitive-science research. If you're like many people, you've forgotten much of your formal education. But studies show that if you repeat things—you take a freshman physics class, say, but continue to use those concepts throughout college—you retain them. Researchers might show refreshers to students at different points in time after a course has been completed, Mr. Mitros says, tracking what they recall." With this kind of study being done, scientists will be able to improve peoples cognitive skills and better education. 
Another benefit of e-lerning is that students can take the classes as they fit to their schedule rather then having to base their day around a class. It can be noticed by most students that as a semester goes on less and less students show up to classes. 
With online classes it is easier for students to see all the lectures. Also students are able to rewind and fast forward their professors. So if they missed important information, forgot something, or didn't catch the message the professor was trying to portray the first time they can go back. And apparently being able to fast forward is beneficial also. "Data showed MIT students tended to watch the videos at 1.5 speed, which makes voices sound almost like chipmunks but delivers information more rapidly." Maybe it is true that every generation is starting to learn things at faster and faster rates.
