Not the same thing. Epistemology is a classification system for knowledge. Metacognition is awareness of the inner workings of your own brain, it's not about classifying the information flowing through it.

In this context, "metacognition" seems to be an education buzzword for a particular approach to optimizing learning. The stuff being talked about here is neither the same thing as epistemology nor immediately obvious from the broader meaning and uses of "metacognition".

its...okay maybe it's a buzzword but it isn't about 'optimized learning' its about valuing the development of a process of learning equally to the content of learning.

It has become a focus because teach to the test has done a damn good job of stripping it away from K-12 classroom learning in the US. Now that we realize whats missing ed researchers talk about it more and how to add it back.

do we really need a word like fruit when we already have planes?
