Deutero learning is concerned with learning how we learn ( our learning frameworks and assumptions that underpin what we learn, values, therein). This represents the transformational idea of Deutero learning which involves seeing things in different ways or other ways through within diverse contexts.
I found this article's examples on the application of Deutero Learning relatable: https://organizationallearning9.wordpress.com/deutero-learning/
"Simple learning was denoted as “proto-learning,” the adaptation of behavior in response to contingencies of reinforcement. Gestalt learning was defined as deutero-learning, the changes in proto-learning as a result of “insight” in the structure (or class) of the situation in which proto-learning takes place." (Visser, 2003, p. 272).
