While yes, Kakashi is a pretty bad teacher, it's not like the Narutoverse has a high standard of teachers. Keep in mind that this world has a mostly a master-apprentice style schooling, where a Jonin master teaches three Genin apprentices.

The Jonin, however, isn't there to teach techniques, he's there to teach them how to function as a ninja. It seems that the clans themselves are expected to teach their kids things like jutsu, although may the clans wanted that kind of power as there are many secret jutsu.
