“The person doing the work does the learning.” That adage is as relevant today as it was when it was first spoken decades (or centuries) ago.
The “doing” of both simple and complex tasks promotes learning.
That’s why many teachers, myself included, report having learned so much more about the subject matter they taught through the complex process of teaching it than they did in universities.
The person doing the explaining does the learning.
The person doing the planning does the learning.
The person doing the assessment of his or her own learning does the learning.
Consistently acting on this adage in every classroom and professional learning venue would change virtually everything.
And it would be a change for the better.
