Abstraction, intuition,…

Abstraction, intuition, and the “monad tutorial fallacy” by Brent Yorgey.

From the post:

While working on an article for the Monad.Reader, I’ve had the opportunity to think about how people learn and gain intuition for abstraction, and the implications for pedagogy. The heart of the matter is that people begin with the concrete, and move to the abstract. Humans are very good at pattern recognition, so this is a natural progression. By examining concrete objects in detail, one begins to notice similarities and patterns, until one comes to understand on a more abstract, intuitive level. This is why it’s such good pedagogical practice to demonstrate examples of concepts you are trying to teach. It’s particularly important to note that this process doesn’t change even when one is presented with the abstraction up front! For example, when presented with a mathematical definition for the first time, most people (me included) don’t “get it” immediately: it is only after examining some specific instances of the definition, and working through the implications of the definition in detail, that one begins to appreciate the definition and gain an understanding of what it “really says.”

Unfortunately, there is a whole cottage industry of monad tutorials that get this wrong….

It isn’t often that you see a blog post from 2009 that is getting comments in 2014!

I take the post to be more about pedagogy than monads but there are plenty of pointers to monad tutorials in the comments.

Another post mentioned in the comments that you may find useful: Developing Your Intuition For Math by Kalid Azad.

What if you ran a presentation from back to front? Started with concrete examples of your solution in action in multiple cases. Explain the cases. Extract the common paths or patterns. Then run out of time before you can repeat what everyone already knows about the area? Would that work?
