James Nottingham's metaphor of The Learning Pit illustrates the struggle before "getting it."
It's the learning journey of approaching a new concept, uncovering conflicts or contradictions with your knowledge, confusion, beginning to put new ideas together and finally the clarity of a new concept mastered.
Here's a nice animated video explaining the Learning Pit if you're curious.
The Learning Pit was created by James Nottingham (2007, 2010, 2017). More details at: challenginglearning.com/learning-pit
