Why isn't every government school K-12 class on the Internet from kindergarten through AP calculus? Hm? What the big cost in videoing a teacher? And...It should be entirely tuition-free to all the citizens of the state regardless of age. Hey! The citizens paid for it. What's the BIG secret?
Should've been done long time ago, but some people and organizations are making too much money annually from printing books, with essentially a fixed material which would cost next to nothing to put on e-books (ePUB / PDF).
What the big cost in videoing a teacher?
That's exactly the problem - it wouldn't be, and in the eyes of educrats it would devalue it. Just like the music industry, the government-educracy axis of the "education industry" is starting to have problems "monetizing" the digital / Internet model and are resisting it because it benefits / frees the parents and students from long-and-carefully established tyranny of "free public education" model.
Obama is actually trying to convert higher education into the same model by having the government take over the student loan process. Harvard, MIT, Stanford and others see where it's going ("loan forgiveness") and are changing their models accordingly, not to be left high and dry with unperforming loans (just like the banks were with CRA mortgages).
This development is the private universities' direct response to the Obama's takeover of student loan industry / process and therefore, clear threat of "loan forgiveness" movement by the OWS (aka 0.99percenters).
They've had the capability of doing it before now (witness MITx) but didn't have the real incentive to go full bore... now they do.
The big secret is the incompetence of some teachers and the brainwashing content of much coursework. If the general public actually had full-time video access to the classrooms of their offspring, they would be appalled at what happens there.
