Study by means of Facilitation

All home-instructionists (if there is such a word) know that:

there is more learning in facilitation
than in study.

Let your child explain the content and skills to you, and/or to other students.
You yourself must want to learn from them, by asking questions.

...and so they will learn to communicate
"without misunderstanding" (I think it was Socrates who said this)

and not:
be UNable to "explain it simply"
because they "don't understand it well enough" themselves (Einstein).
