From Literacy to Humanagogy: Unpacking Adult Education Terminology

Adult education has its own rich vocabulary – a set of specialized terms that go far beyond simply “teaching grown-ups.” Whether you are stepping into the field as an educator, a policymaker, or a lifelong learner yourself, understanding this language is essential. Terms like literacy, numeracy, andragogy, and humanagogy are not just jargon; they represent distinct ideas about how adults learn, what they need, and how education can be designed to serve them better. This post breaks down each of these key terms clearly and precisely.

What does literacy really mean? 🔗

At its most basic level, literacy refers to the ability to read, write, and comprehend written information. But it is important to understand that literacy is not a binary condition – it is not simply something you either have or do not have. It exists on a spectrum, and its meaning has evolved significantly over time.

A literate person is one who can read and write with sufficient competence to manage everyday tasks – reading a notice, filling in a form, or writing a short message. An illiterate person, by contrast, lacks these foundational skills entirely. According to the UNESCO Institute for Statistics, around 750 million adults worldwide – including 102 million young people between 15 and 24 – cannot read or write even a simple sentence. This figure highlights just how pressing the issue of basic literacy remains globally.

It is equally important to recognize that illiteracy does not arise solely from lack of schooling. Adults can lose literacy skills if they are not regularly used after their school years, a phenomenon sometimes described as relapsing into functional difficulty. This distinction becomes clearer when we move to the concept of numeracy.

Numeracy and innumeracy 🔗

Numeracy refers to the ability to understand, use, and apply numbers and basic mathematical concepts in everyday life – reading a price tag, calculating change, understanding a dosage on a medicine bottle, or interpreting data in a news report. A numerate person can navigate these situations with confidence.

An innumerate person, on the other hand, struggles with these basic numerical tasks. Innumeracy is often overlooked in public discourse because it carries less social stigma than illiteracy, yet its consequences in daily life can be equally limiting. The UNESCO UIS treats literacy and numeracy as inseparable competencies under Sustainable Development Goal 4, specifically Target 4.6, which calls for ensuring that all adults achieve at least a fixed level of proficiency in both skills by 2030.

Literacy and numeracy together form the bedrock of what educators call functional literacy – a concept that deserves its own careful examination.

Functional literacy: beyond reading and writing 🔗

The term functional literacy was initially defined for UNESCO by William S. Gray in 1956 as training adults to meet independently the reading and writing demands placed on them. Since then, the definition has been considerably expanded to reflect the growing complexity of modern life.

Today, the UNESCO Institute for Statistics defines functional literacy as the capacity of a person to engage in all those activities in which literacy is required for effective functioning in their group and community, and to continue using reading, writing, and calculation for their own and their community’s development.

This is a crucial distinction. A person can technically “know how to read” and yet still be functionally illiterate – meaning they cannot apply that skill effectively in real-world contexts. Consider someone who can decode words on a page but cannot understand a tenancy agreement, follow medical instructions, or interpret a bank statement. Research published in the journal Frontiers in Psychology notes that functional illiteracy appears in everyday life in tasks such as opening bank accounts, reading food ingredients, understanding medication instructions, signing contracts, and more.

In adult education, this understanding of functional literacy shapes programme design significantly. Programmes are not just about teaching letters and numbers – they aim to build the competence needed to participate fully in social, economic, and civic life. Functional literacy has three broad programme levels: eradication of basic illiteracy, skills coaching, and independent learning, each targeting a different tier of need.

Why functional literacy matters in adult education contexts 🔗

In developing countries, outright illiteracy remains the central challenge. In more developed societies, however, it is functional illiteracy that is prevalent – people have attended school, yet many cannot navigate the demands of modern life. According to a review in Frontiers in Psychology, while approximately 85% of adults worldwide are technically literate, large-scale assessments reveal that functional illiteracy is widespread in developed countries. This makes adult education programmes specifically targeting functional literacy a critical policy priority everywhere.

Pedagogy: the original model of teaching 🔗

To understand adult education theories, you first need to understand pedagogy – the traditional model against which adult learning theories are often defined. The word comes from the Greek paid (child) and agogus (leader), literally meaning “the art and science of teaching children.”

Pedagogical methods, which evolved in the monastic schools of Europe between the 7th and 12th centuries, are fundamentally teacher-directed. The instructor decides what is learned, how it is delivered, and when. The learner is largely passive – a recipient of knowledge. Teaching is content-driven, relying heavily on fact-laden lectures, rote memorisation, drills, and standardised assessments.

For children, who are still building foundational knowledge and depend on structure and guidance, this approach has genuine value. However, as Malcolm Knowles observed in 1968, the biggest obstacle to adult education had been its dependence on methods designed for children – methods that adults resisted because they did not fit their motivations, their life experiences, or their immediate learning needs. This observation gave rise to a new framework: andragogy.

Andragogy: the theory of adult learning 🔗

Andragogy is defined as the art and science of helping adults learn. The term was first coined by the German educator Alexander Kapp in 1833 but remained largely unused for over a century. It was revived in the early 20th century by Eduard Lindeman, who emphasised discussion-based, experience-centred learning for adults. The framework gained its full theoretical shape in the late 1960s and 1970s through the work of American educator Malcolm Knowles.

The word andragogy comes from the Greek andr- (adult male) and agogos (leader) – literally “leading men,” in contrast to pedagogy’s “leading children.” In contrast to pedagogy, andragogy is grounded in a humanistic view of learners as self-directed and autonomous individuals, where the teacher’s role is that of a facilitator rather than a transmitter of knowledge.

Knowles’ core assumptions about adult learners 🔗

Knowles built andragogy around a set of key assumptions about adult learners that distinguish them from children. These assumptions, as outlined at the infed.org encyclopedia of informal education, are:

• Self-concept: As a person matures, their self-concept shifts from dependency toward self-direction. Adults want autonomy in their learning.
• Experience: Adults accumulate a growing reservoir of experience that serves as a rich resource for learning.
• Readiness to learn: Adults become ready to learn things that relate directly to the developmental tasks of their social roles.
• Orientation to learning: Adults shift from a future-application mindset to one of immediate application – they want to use what they learn now, not later.
• Motivation: Adults are primarily driven by internal factors – personal growth, career development, self-improvement – rather than external rewards or grades.

These assumptions have practical implications for educators. Andragogy calls for flexibility, learner involvement, problem-centred content, and a respect for the life experiences adult learners bring to the classroom. Rather than presenting abstract theories, adult educators guided by andragogy connect learning directly to real problems their learners face.

Andragogy in practice 🔗

The principles of andragogy are applied widely today – in workplace training programmes, professional development courses, community education, and online learning platforms. A study published in PLOS ONE applying andragogical principles to biomedical research training found that approximately 85% of learner feedback could be linked to at least one andragogical principle, demonstrating its practical relevance even in highly specialised training contexts.

That said, andragogy has its critics. Some scholars argue that the distinction between child and adult learning is not as sharp as Knowles suggested, and that effective learner-centred principles may apply across age groups. Western Governors University notes that pedagogy, andragogy, and the more recent heutagogy (self-determined learning) are best understood as a continuum of learner autonomy, not as rigid, age-based categories. Even Knowles himself later acknowledged that andragogy and pedagogy represent two ends of a spectrum, with both applicable across different situations.

Humanagogy: a unified, human-centred approach 🔗

The debate between pedagogy and andragogy eventually gave rise to a third term: humanagogy. Proposed by Knudson in 1980, humanagogy was put forward as a replacement for both pedagogy and andragogy because it combines the best of both frameworks.

As published in the Journal of Technology Studies (Virginia Tech), Knudson proposed humanagogy because it is pedagogy and andragogy combined – representing the differences as well as the similarities that exist between both adults and children as learning human beings. It treats human learning as a matter of degree, not of kind.

Humanagogy is premised on the idea that ignoring the principles of pedagogy in adult education excludes valid lessons from how human beings learn across the whole lifespan. As noted in EBSCO’s research overview of andragogy, terms like humanagogy, anthropogogy, and the African concept of ubuntugogy all emerged from scholars who objected to the separatist focus of both pedagogy and andragogy, seeking instead a humanitarian, all-encompassing educational methodology.

What makes humanagogy distinctive 🔗

Where andragogy focuses on the methods and conditions of adult learning, humanagogy takes a more holistic view. It recognises the learner not just as an adult who needs relevant, practical knowledge, but as a whole human being – with emotions, social relationships, personal aspirations, and a developmental journey that stretches from birth to death. Learning, in this framework, is not merely about acquiring competencies; it is about personal transformation.

This approach has particular relevance for adult education because adult learners frequently come to the classroom at significant life crossroads – navigating career changes, recovering from setbacks, or seeking to rebuild their confidence and sense of agency. A purely skills-focused curriculum often falls short of addressing these deeper dimensions. Humanagogy calls on educators to create environments that are not only intellectually stimulating but also emotionally supportive, inclusive, and affirming of the learner’s full humanity.

Knudson’s humanagogy can be thought of as a synthesis. Using his own metaphor, pedagogy and andragogy are like the Chinese symbol of yin and yang – at the same time opposites and complements, each necessary, neither complete on its own. Humanagogy holds both in balance.

Bringing the terms together 🔗

Taken together, these terms form a conceptual map of the field of adult education. Literacy and numeracy define the foundational skills adults need to function in society. Functional literacy extends this to encompass the practical application of those skills in real-world contexts. Pedagogy provides the historical baseline of teacher-directed instruction that adult education has progressively moved away from. Andragogy articulates why adults need a different educational approach – one that respects their autonomy, builds on their experience, and connects learning to immediate life needs. And humanagogy reminds us that beneath every learner – child or adult – is a human being whose growth cannot be reduced to skills and knowledge alone.

For educators working in adult learning contexts, fluency in this vocabulary is not merely academic. These terms carry real implications for how programmes are designed, how classrooms are facilitated, and how learners are supported. Understanding the distinction between a literate and a functionally literate adult, for instance, can change how a literacy programme is structured entirely. Recognising when andragogical principles are appropriate – and when a more humanagogical lens is needed – can make the difference between a course that informs and one that genuinely transforms.

What do you think? How might the shift from a purely andragogical approach to a humanagogical one change the design of adult education programmes in your context? And do you think the concept of functional literacy – as distinct from basic literacy – is well understood by policymakers and educators in your region?
