Having studied how humans learn, both are important factors. Genetics determines the upper limit, and teaching and practice determines if you reach that limit.

But when it comes to teaching, it is important to teach both how to learn, as well as basic concepts to build upon. By teaching the child these words and concepts, they can then expand from there. They can get curious then use their training on "how to learn" to learn more about the topics presented.

To successfully teach a child, you have to do both.
