Well, education researchers are trying to communicate that knowledge is never "transferred".

IIRC (I don't recall where I read about this), there are two problems:

1. "transfer" gives the impression that a person can copy their knowledge to another person, but that is not the case. The teacher says, writes the words or even demonstrates, but the brain in the student is making its own connections and tries to explain it in its own frame of reference. It may click, or may not, or may even click in the wrong way, leading to learning a different lesson from the one being taught.

2. The teacher may have tacit knowledge they do not know they have to teach, or convey by some other means. Most teachers don't even realize that this tacit knowledge is not present in their students.

So, maybe nitpicking a bit, but "transfer" is not the right word for it.
