I'm not sure what a 3 step methodology is, so I can't answer that way. From what I know about this subject, she is proposing communicating to children that they have the ability to alter their own abilities. This is in contrast to the attitudes like "I am just not good at math" or "They did it easily because they're gifted". These attitudes are undesirable because challenges (things that you cannot currently do) are avoided rather than attempted.
