What is learner variability?

What is learner variability?

"There is no average brain. 

Variability is the dominant feature of the nervous system. Like fingerprints, no two brains are alike."

UDL and the Learning Brain | CAST (2018, PDF)

 

Every learner brings unique and varied experiences, strengths, skills, knowledge and intersecting identities to learning.

They also bring differences in:

  • how they are motivated and engage in learning
  • how they perceive, access and make sense of information
  • how they use tools, take action, express ideas and demonstrate understanding.

Planning with learner variability in mind at the outset is central to UDL.

Why variability matters

Why variability matters

Dr Todd Rose, Harvard University, talks about why planning for variability is critical.

Planning for predictable variability

Planning for predictable variability

UDL helps us consider variability across 4 dimensions.

UDL has traditionally emphasised the variability among learners in:

  • engagement – the "why" of learning
  • representation – the "what" of learning
  • action and expression – the "how" of learning.

UDL Guidelines 3.0, the latest iteration, expands this view to include: Identity – the "who" of learning:

  • Recognising that learners bring multiple, intersecting identities (for example, cultural, linguistic, racial, gender-based).
  • Acknowledging that identities shape how learners engage with, perceive, and express their learning.

Identity is not a separate category but is interwoven across all three UDL principles.

In this video, David Rose discusses the importance of providing learning supports and structures that are tailored to students’ individual needs and abilities. He shares his vision for “de-standardizing” education to help students discover their strengths and become expert learners.
