Watching his videos highlights how little the Web has changed higher education. Many online courses at traditional colleges simply replicate the in-person model—often in ways that are not as effective. And what happens in most classrooms varies little from 50 years ago (or more). Which is why Mr. Khan's videos come as a surprise, with their informal style, bite-sized units, and simple but effective use of multimedia.
Mr. Khan has a vision of turning his Web site into a kind of charter school for middle- and high-school students, by adding self-paced quizzes and ways for the site to certify that students have watched certain videos and passed related tests. "This could be the DNA for a physical school where students spend 20 percent of their day watching videos and doing self-paced exercises and the rest of the day building robots or painting pictures or composing music or whatever," he said.

Taken together, the findings imply that student evaluations give instructors-especially those who do not have tenure-incentive to teach in ways that "have great value for raising current scores, but may have little value for lasting knowledge," the authors conclude.

The researchers and educators in this small, emerging field see clear advantages to using real-world sites as the backdrop for educational games.
A major goal of Mentira is to motivate students "to get their heads out of the textbook" by showing them that language has a vibrant local context, Ms. Sykes says. By setting the story in a nearby neighborhood, she and Mr. Holden took advantage of its historic sites and folklore to integrate learning about its history and culture into the game

Mr. Gagnon is the lead developer of a software tool called ARIS, or Augmented Reality and Interactive Storytelling. ARIS lets designers link text, images, video, or audio to a physical location, making the real world into a map of virtual characters and objects that people can navigate with iPhones, iPads, or iPod Touches.
