When teaching, do you give 2 examples? or an example + explanation?
2 examples allow learner to struggle and come up with principle on their own. #knowledgebuilding #learninghuman
also better to watch experts do the task than instructional videos CC:

FWIW, I find that teasing the principle by going through a few examples before the reveal to be quite effective. Leverages the human ability to generate patterns.
Another cool idea is to use formative assessment during teaching, though I think you might already know this: you throw out a multiple choice question and get students to raise their hands; which answer they pick tells you what mistaken mental model they currently hold.
