Help track the spread of walking undead this season with some great photos!

Who orders books? A classroom teacher. Who writes the curriculum? A classroom teacher. Who handles discipline? A classroom teacher.

Evaluations are done by peers, and the tools are developed by teachers. Teachers are hired by other teachers. There are no outside consultants, no central office administrators, and no superintendents.

Let it be the person who pays the electrical bill, who makes sure everyone gets paid, who is a sounding board for teachers. Let it be someone who still has to lesson plan, grade and walk in front of a room of children every day and figure out what's best for them, one day at a time.

Have you ever seen a grassy lawn on a college campus with a multitude of little dirt paths criss crossing it? Each trail is worn by students making the same decision, branching where someone thought to head somewhere new and others followed. That’s the right model for how we should let students teach themselves.

We need writers, and filmmakers, and animators, and everyone else who generates educational content. We need editors and watchdogs to evaluate the content and make sure it is good. We need teachers who can hold students hands as they walk their educational path, and who can inspire them to explore areas they may find boring at first. We need supervisors and tests to evaluate how well this system is working. We need parents and communities to decide our expectations for that system. We need all those things.

The future of education doesn’t depend on us digitizing and updating textbooks, it will rely on us leaving the textbook format behind entirely.

Let’s start with what Khan Academy is. Khan Academy is a collection of video lectures that give demonstrations of mechanical processes. When it comes to this purpose, KA videos are, on the average, pretty good. Sal Khan is the main reason; he is approachable and has a knack for making mechanical processes seem understandable. Of course, his videos are not perfect. He tends to ramble a lot and get sidetracked; he doesn’t use visuals as effectively as he could; he’s often sloppy and sometimes downright wrong with his math; and he sometimes omits topics from his subjects that really need to be there (LU decomposition in linear algebra, for example). But on balance, KA is a great resource for the niche in which it was designed to work: giving demonstrations of mechanical processes.

But let’s also be honest about what Khan Academy is not. Khan Academy is not a substitute for an actual course of study in mathematics. It is not a substitute for a live teacher. And it is not a coherent curriculum of study that engages students at all the cognitive levels at which they need to be engaged. It’s OK that it’s not these things. We don’t walk into a Mexican restaurant and fault it for not serving spaghetti. I don’t fault Khan Academy for not being a complete educational resource, because it wasn’t designed for that purpose. Again, Khan Academy is a great resource for the niche in which it was designed to work. But when you try to extend it out of that niche — as Bill Gates and others would very much like to do — all kinds of things go wrong.

When we say that someone has “learned” a subject, we typically mean that they have shown evidence of mastery not only of basic cognitive processes like factual recall and working mechanical exercises but also higher-level tasks like applying concepts to new problems and judging between two equivalent concepts. A student learning calculus, for instance, needs to demonstrate that s/he can do things like take derivatives of polynomials and use the Chain Rule. But if this is all they can demonstrate, then it’s stretching it to say that the student has “learned calculus”, because calculus is a lot more than just executing mechanical processes correctly and quickly. To say that it is not — that knowledge of calculus consists in the ability to perform algorithmic processes quickly and accurately — is to adopt an impoverished definition of the subject that renders a great intellectual pursuit into a collection of party tricks.

Have you ever tried to convey the feeling of walking through your favorite park? Or have you wanted to create an interactive tour of a memorable journey? Well, starting today, it's now possible for you to build your own Street View experiences to do just that. Using a new feature in our Views community, you can easily connect your photo spheres to create 360º virtual tours of the places you love, then share them with the world on Google Maps.
