I didn't fully understand meta-learning until I started reading neuroscience books. Find some introductory text book on neuroscience (Amazon). Then read a book that explains extensively on various forms of neural plasticity. Developmental neuroscience also provides crucial insights Once you understand the fundamental mechanism of how the brain learns, all the methodology behind meta-learning can be derived. (e.g. practice science) Because the brain is a complicated machine and only recently has evolve more complex types of learning, so I personally think it's more important to understand its limitations, (e.g. when you are not learning, or why you can learn physical skills faster than mental skills etc.)
