I interestingly misinterpreted this to mean that it was an education program that taught only what could not be trivially Googled. This struck me as a plausible first pass for what should be left untaught.

If all you know is that it's an early-learning education program called TOOLS, you can't google it, unless you know a way to make google case-sensitive. There are many educational tools. (And I don't even know if it's capitalized. I'm listening to the book on audio.)

I think he means that it's nearly impossible to find information about it online, either because it's hardly heard of, or the fact that the name makes it very difficult to isolate, or some combination of the two.

(If it's the same as "Systems and Tools Educational Model", it should be fairly easy to find. If it isn't, I guess that's proof in favor of the author's assertion there.)
