Part 2: Why UDL
The goal of UDL, and why there is no average learner.


Start with the Goal
In Part 1 you met the goal of UDL: learner agency. The Why UDL? poster connects that goal to how we learn.
- The affective networks are the “why” of learning. Multiple Means of Engagement helps learners become purposeful and reflective.
- The recognition networks are the “what” of learning. Multiple Means of Representation helps learners become resourceful and authentic.
- The strategic networks are the “how” of learning. Multiple Means of Action & Expression helps learners become strategic and action-oriented.
UDL asks us to design so that every learner can grow in these three ways.
There Is No Average Learner
In 1945, a newspaper in Ohio ran a contest to find the woman whose body matched Norma, a statue built from average measurements. Thousands of women entered. None of them matched.
My article Who Is Martha Skidmore? tells that story. It then traces where the idea of the average came from, how it shaped schooling and special education, and why UDL starts with variability instead.
UDL starts from a different place. Every learner varies, so we plan for that variability from the start.
What We’re Really Talking About
When I talk with schools about UDL, these are the five ideas I mean. They come from my poster What We’re Really Talking About When We’re Talking About UDL.
- Creating the Conditions for Belonging
- Believing In, and Empowering, Every Learner
- Embracing Variability
- Understanding that Barriers Exist in the Design of Learning Experiences and the Environment, Not the Learner
- Engaging in the Iterative Design Process
You will come back to the fourth idea in Part 5.

Choose one:
- Skim Who Is Martha Skidmore? and come back later to read it in full.
- Open the Why UDL? poster and find the network that matches the lesson you brought with you.
Beth’s Tip
The Martha Skidmore story works well at the start of a staff meeting. Most people have never heard it, and it opens the conversation without blaming anyone.
Reflect
Where does the idea of an average learner still show up in your school? Think about timetables, textbooks, tests and reports.
