Exploration of adult learning theory, andragogy, which includes five assumptions and six principles, formal/informal/non-formal learning, and application to instructional design.
Andragogy, often referred to as the theory of adult learning, provides one of the most influential foundations in modern instructional design. It shifts the focus from how we teach children (pedagogy) to how adults learn,and why they learn differently.
The term was first introduced by Alexander Kapp in 1833, but it wasn't until the 1970s that Malcolm Knowles brought it into practical relevance. Knowles didn't present andragogy as an opposing theory to pedagogy, but as a complementary one,recognising that adults bring unique life experiences, motivations, and expectations into learning environments that must be factored into instructional strategy.
His work gave rise to two main frameworks:
These assumptions describe how adult learners differ from younger learners:
Building on these assumptions, Knowles outlined six principles to guide adult learning environments:
Andragogy also gives us a lens to better understand the contexts where adult learning occurs:
In reality, adult learners often move fluidly between all three. As instructional designers, our role is to design content that's flexible enough to meet learners where they are, while still providing structure when it's needed.
"Andragogy isn't a formula. It's a framework. It reminds us that adult learning must be relevant, respectful, and responsive to lived experience"
This model has influenced everything from online course design and workplace training to continuing education and community development. At its core, andragogy pushes us to stop treating learners as blank slates and start treating them as capable, experienced contributors. It encourages us to design learning that is authentic, problem-based, and aligned with real goals, not just for passing assessments, but for improving performance, behaviour, and confidence in the real world.
While andragogy focuses on how adults learn, pedagogy refers to traditional approaches used to teach children. In pedagogy, the teacher is the authority figure, responsible for deciding what is learned, how it's taught, and when it's assessed. Learners are typically seen as blank slates. Andragogy, by contrast, is built on the idea that adults bring existing knowledge, life experience, and a desire for relevance and autonomy into every learning experience.
Andragogy gives instructional designers a practical framework for designing learning that respects adults' time, experience, and goals. It reminds us that designing for adults isn't about simplifying content, it's about creating space for autonomy, purpose, and growth.
Andragogy offers more than just a theory. It gives us a grounded, realistic way to design learning for people who already have jobs, habits, and lived experience. The shift from pedagogy to andragogy isn't about age, it's about mindset. Adults don't want to be lectured or led through every step. They want learning that's relevant, efficient, and worth their time.
This is why andragogy connects so strongly to problem-based learning. Instead of starting with definitions or theory, adult learners respond better when we open with a real task or scenario. For example, asking someone to improve a process they actually use makes the learning feel purposeful, something they're solving, not just studying. It ties directly to Knowles' idea of readiness and orientation to learning.
We also see a clear connection in how we handle experience. Adults bring opinions, habits, and context with them. If the design ignores that, it creates friction. If it uses it, through reflection prompts, peer discussions, or applied examples, it makes the learning more personal and more memorable.
Feedback and assessment also work differently. Rather than focusing on "right" answers, it's more useful to ask learners to apply, adapt, or critique. A short simulation or task-based submission tells us more about how someone thinks than a multiple-choice quiz ever could. Again, it's a shift, from checking knowledge to building capability.
The bottom line: Andragogy changes how we design everything, from tone and structure to the types of practice we offer. It reminds us that we're not just teaching content, we're working with learners who expect to use it. That's where the design needs to meet them.
German educator Alexander Kapp first introduced the term andragogy to describe Plato's ideas about adult education. While it didn't gain traction at the time, it marked the beginning of efforts to define adult learning as something distinct from pedagogy.
The term was revived and used more practically in Germany by Eugen Rosenstock-Huessy, who began applying andragogical approaches in adult education settings. He emphasized that teaching adults required different methods than teaching children.
Malcolm Knowles published "Andragogy, Not Pedagogy". Formally introducing the concept to American educators. He positioned adult learners as self-directed individuals with unique needs and experiences, a turning point in the development of adult learning theory.
Andragogy changes the way I think about designing learning for adults. It's not just about structuring content neatly or pushing information out. It's about recognising that adult learners come in with experience, expectations, and a clear need for relevance (and the design has to respect that from the start).
One of the biggest shifts is focusing on why the learning matters. Adults want to see the purpose up front. That means I look for ways to tie content directly to their work or personal goals, whether it's through realistic case studies, scenarios, or problem-based activities that mirror what they actually do. When the relevance is obvious, engagement changes completely.
Andragogy also pushes me to consider what learners already know. Adults arrive with established ways of thinking and doing. If the design ignores that, it risks either redundancy or resistance. So I build in places for learners to connect new ideas to their own experiences, to compare, question, and adapt what they already use. Sometimes that's through reflective prompts, other times through activities that surface their existing approaches before introducing new ones.
Another implication is how learning is structured. Adults value autonomy. They want flexibility, in pace, in how they navigate the material, and sometimes even in the order they tackle topics. Modular design, choice points, and tools that let them set personal goals all support that need for self-direction.
Assessment follows the same logic. Rather than just testing recall, I try to design assessments that feel like meaningful tasks. It's more useful (and often more motivating) to have learners apply a concept to a real problem, critique a case, or produce something they can actually use, instead of ticking off quiz scores.
Andragogy fits naturally into corporate learning, where employees bring experience, expect practical outcomes, and often juggle multiple responsibilities alongside training. Its emphasis on relevance, self-direction, and immediate application makes it well suited to professional environments. But like any framework, it also comes with limitations that need to be managed.
"Andragogy is highly effective in corporate settings where learners value relevance, autonomy, and respect for their experience. But it still needs structure, clear purpose, and thoughtful scaffolding to truly deliver"
Andragogy is more than just a theory about adult learning, it's a practical framework that shapes how we build training that respects who learners are and what they bring with them. Unlike traditional approaches that often treat learners as blank slates, andragogy starts with the idea that adults arrive with experience, expectations, and a clear sense of purpose.
Malcolm Knowles helped define this shift in the 1970s, outlining core assumptions that still guide instructional design today: adults value relevance, draw heavily on prior knowledge, prefer problem-solving over abstract theory, and want learning that respects their autonomy. That's why modern training often centres on realistic scenarios, reflective prompts, and flexible structures that let learners explore content on their terms.
It also highlights how adults learn across contexts, not just in formal courses, but in non-formal settings like workshops and webinars, and informal spaces like peer conversations or on-the-job experimentation. Good design acknowledges this mix, supporting learning that happens both inside and outside structured programs.
In corporate environments, andragogy fits naturally with professional realities. It's built for people balancing work, life, and learning. People who want to know why a topic matters before investing time, and who expect practical takeaways they can apply immediately. At the same time, it highlights a balance every designer has to manage: giving learners control and respect for their experience, while still providing enough structure and guidance to meet shared goals.
Andragogy reminds us that designing for adults isn't about simplifying content. It's about creating learning that is relevant, challenging, and built on trust.
