Questions are more powerful than answers. My kids are 29 & 31 now. I'd suggest that they master how to ask well formed questions. Also, "The medium is the message" is from Marshall McLuhan (Understanding Media: The Extensions of Man 1964)
Your children are about to reach an age where they have a better formed understanding of the world than you. Might serve you well to see what you can learn from them.
How would you recommend they learn to ask well-formed questions?
