The Essentials of Adult Learning Theory: What Every Facilitator Should Know

After taking a gap year after university, it was in 2000 that I embarked on a year-long Post Graduate Certificate in Education (PGCE), and that is where I started to really explore the science of learning design and delivery. More recently, in a number of supervision and training sessions, Adult Learning Theory has been a topic of particular note. I thought that it might therefore be useful to outline how Adult Learning Theory impacts curriculum and assessment design, as well as facilitation choices.  Here goes!

As coach educators, facilitators and trainers, we often focus on what we teach – competencies, skills, models, frameworks, tools, techniques… Yet the real leverage sits in how adults learn.  Adult Learning Theory does not need to be heavily academic or intimidating because – at its heart – it simply helps us design learning that respects experience, builds motivation, and can be useful right away.

Adults Are Not Empty Vessels

One of the most influential contributors to adult learning was Malcolm Knowles, who introduced the concept of andragogy. His work highlighted that adults learn differently from children because they bring life experience, identity, and choice into the room.

Adults tend to:

  • Be self-directed and want agency.
  • Learn best when content is relevant to real life.
  • Draw heavily on prior experience (for better and worse).
  • Be motivated internally (purpose, growth, meaning).

For coach educators and facilitators, this means moving beyond ‘delivery’ and towards the coach-like behaviour of partnership in learning.

Experience Is the Curriculum

Learning does not start when the session begins – it starts with what learners already know and bring with them.

David Kolb described learning as a cycle involving experience, reflection, conceptualisation, and experimentation. Course delivery often leans heavily on discussion and theory, but adults learn most deeply when all parts of the cycle are present.

Practical implications:

  • Build in structured reflection, not just discussion.
  • Encourage learners to test ideas between sessions.
  • Treat lived experience as valid data, not anecdote.
  • Create space for playfulness and ‘doing’.

Meaning Matters More Than Content

Adults do not just acquire skills; they revise beliefs, assumptions and identity while learning. This is where Jack Mezirow made a significant contribution. His research showed that adult learning often involves perspective transformation – a shift in how people see themselves or the world.

In coaching education and facilitation, this might show up as:

  • A coach rethinking ‘fixing’ versus partnering.
  • A leader reframing authority as facilitation.
  • A practitioner challenging long-held habits.

Learning design should therefore create an environment of safe challenge – enough disruption to provoke insight, without tipping into threat.

What This Means for Your Facilitation

When adult learning theory is applied well, sessions become more engaging and impactful.

Consider the following design principles:

  • Start with why before what.
  • Explore prior knowledge and learning before ‘telling’ or ‘teaching’.
  • Invite choice wherever possible.
  • Use real cases over hypothetical ones.
  • Balance input with reflection and application.
  • Normalise uncertainty and learning-in-progress.

Putting The Pieces into Practice – How Will Learners Know? 

When we design learning with adults in mind, rather than for adults, we unlock deeper engagement, stronger transfer and more confident practitioners.

As facilitators, our role is not to be the expert in the room but, instead, to create the conditions in which adults can learn, unlearn and relearn with purpose.

When adult learning principles are embedded well, learners notice it quickly – not because you tell them, but because it feels different.

In practice, this means:

  • Designing sessions that respond to the group and embody flow, not rigid slide order.
  • Allowing learning pathways to emerge rather than controlling outcomes.
  • Making space for reflection, dialogue and ambiguity.
  • Treating questions as contributions, not interruptions.
  • Actively inviting challenge, feedback and co-creation.

Learners will know adult learning theory is at work because:

  • They feel trusted to think for themselves, and to be themselves. 
  • Their experience is used, not sidelined.
  • Learning feels relevant immediately.
  • They leave with insight and something to try.
  • They feel more capable, not more dependent on the trainer.

You may hear this reflected back in phrases such as:

“That really connected to my work.”
 “I felt stretched, but supported.”
 “I’m noticing things differently already.”

These signals matter becasue they indicate that learning has moved beyond content absorption and into meaning-making – this where adult learning truly happens.
