Epistemology in the school?

In the school metacognition is handled as thinking about learning and thinking, like an accessoire. Why not start with action-based epistemology? Epistemology as inquiry of knowledge and justified beliefs; developmental epistemology from the beginning rather than the moral and / or psychology of tasks. Epistemology as a data (experience) based trajectory growing like a rhizome.
