The first quote, from the partial order link, said some parts have one thing that preceeds the other (and some parts don't ). An example is that my kid has done the first few pages of an algebra book. He had to skip the problems that had fractions and decimals. He's barely worked with those. For those problems knowing fractions and decimals preceeded doing the math. For the other problems, it didn't.
I (think) it's okay to show kids things they're not going to "get" it all the first time. I think learning new things means looking at stuff that some of it you know and some of it you don't know.
