Extended data

Proficiency is a state in which learners can transfer knowledge. That is to say, on the surface, the same kind of knowledge has some commonalities, and learners have mastered the commonalities of different categories or even different fields of knowledge, thus transferring deeper understanding from one field to another. I think this is a mastery of knowledge.

So how to master knowledge? First of all, we should have a deeper understanding of each category or a certain problem, abstract common rational knowledge from it, and then store it in memory. Then study and think about other categories, and then abstract other commonalities. When learners find some commonalities in abstraction, they can connect the knowledge in different fields. The way of thinking in one field can be transferred to another. This completes the transfer of knowledge.
