Learning Design Thinking requires both experiential and social learning. It is like learning to ride a bicycle, it is very much an experience of "doing" - experiential. You cannot learn how just by having someone explain it to you—you have to actually try to do it yourself to find your own balance. You also need to practice to get better.
You can also increase your understanding by observing and interacting with more advanced practitioners—in this way, it is social. You enhance your understanding by practicing with your peers, sharing perspectives, and giving each other feedback.
This learning combination of the experiential and the social means thinking of design as craft rather than design as a codified process or design as an outcome. Think “knitting circle” rather than “classroom.”
