I call this approach of Albert Einstein as the acid test of understanding a newly learned concept. 

It includes:

- your ability to articlate what you have just learned;

- your ability to draw examples from your own experience, to illustrate it, where feasible;

- your ability to connect it to other already-known concepts in your headspace;

- your ability to apply it intelligently in a novel or different context;

This is akin to one of the principal tenets of the famed Feynman Technique.
