What's a learning arc?

Learning has never been a straight line. How a student gets from one place to another, is an individual journey. In a classroom of 25 students, there are 25 learning journeys happening. So, a learning arc is a way to describe these individual learning adventures. The arc of the character. Please join me in thinking about what pathways, scaffolds, tools, ideas, technologies help students and their teachers get to understand and use, the arc of learning for preparing for citizenship and life in the 21st Century
