Knowledge is far more than a collection of facts stored in memory. It takes many forms, operates at different levels, and serves different purposes depending on the context in which it is acquired and used. For educators especially, understanding these facets of knowledge – the distinct dimensions through which knowledge can be categorized and examined – is essential for designing meaningful learning experiences. From concepts that exist only in the mind to skills learned through hands-on practice, from truths that hold across the globe to wisdom passed down within a single community, knowledge is a rich and multi-dimensional phenomenon. This post unpacks four key distinctions: abstract vs. concrete, theoretical vs. practical, universal vs. local, and school vs. non-school knowledge.

Abstract vs. concrete knowledge
One of the most fundamental distinctions in knowledge is between what is tangible and what is conceptual. Concrete knowledge refers to information tied to the physical world – things that can be observed, touched, measured, or directly experienced. As curriculum scholars note, concrete thinking operates at the surface level, dealing with facts as they are. Knowing that water boils at 100°C under standard pressure, identifying bird species from their physical features, or learning to build a wooden structure with a hammer and nails – these are all examples of concrete knowledge. It is real, tangible, bound by time and place, and does not require deep inference or abstraction.
Abstract knowledge, on the other hand, involves understanding ideas and concepts that have no direct physical form. According to IGNOU’s B.Ed. study materials, abstract knowledge goes beneath the surface of facts – it is intrinsic, figurative, and not necessarily bound by time or place. Grasping the concept of gravity without physically experiencing it, understanding Einstein’s theory of relativity, thinking about justice or equality, or working with algebraic equations – these require the mind to reason, infer, and construct meaning beyond what the senses can directly perceive.
The key difference is depth of thinking. Concrete knowledge does not demand reasoning beyond the obvious; abstract knowledge requires learners to engage in interpretation, reflection, and the construction of meaning. As educational philosopher V.K. Maheshwari explains, concrete words help us describe things while abstract words help us classify and conceptualize them – and both are necessary for a complete understanding of the world. Importantly, acquiring abstract knowledge is more demanding: it requires prior experience and special cognitive training, which is why scaffolding abstract learning through concrete experiences is a core principle of good pedagogy.
Theoretical vs. practical knowledge
Another critical facet of knowledge concerns how it is used – whether it exists primarily as conceptual understanding or as the ability to act. Theoretical knowledge teaches the why behind phenomena. It is the kind of learning that happens through textbooks, lectures, and study – understanding the laws of thermodynamics, the principles of algebra, or the theories of child development. As IGNOU’s curriculum notes highlight, theoretical knowledge allows learners to understand concepts in context, grasp the reasoning behind events, and question why certain processes work the way they do. It builds a broader mental framework that enables strategic thinking.
Practical knowledge, by contrast, is gained through direct experience, training, and hands-on application. It is knowing how – how to balance a budget, repair a bicycle, treat a common cold, or manage a classroom. A teacher may study learning theories extensively, but it is through actual classroom experience that they learn to respond to a student’s confusion in real time, adapt a lesson mid-way, or manage competing needs among thirty different learners.
The two forms are not in competition – they are deeply interdependent. Research in curriculum studies consistently shows that complex cognitive skills cannot be developed independently of content knowledge. A medical student who knows the theory of anatomy must still undergo clinical practice to become a competent doctor. As Maheshwari notes, theoretical knowledge helps in understanding why one technique works where another fails – it shows the whole and builds the context – while practical knowledge translates that context into effective action. Both make us better at whatever we do.
Universal vs. local knowledge
Knowledge also differs in its scope of applicability. Universal knowledge refers to facts, principles, and concepts accepted across the world, regardless of cultural or geographic context. Newton’s laws of motion apply whether you are in a laboratory in London or a classroom in Chennai. The Pythagorean theorem holds true regardless of cultural background. The structure of DNA is identical across all human beings. As education scholars describe it, universal knowledge is built on science, cumulative research, and verified human experience – it is accepted and applicable by all, transcending the limits of any one time or place.
Local knowledge, by contrast, is rooted in specific communities, cultures, and environments. Educational researchers categorize local knowledge – also known as traditional or indigenous knowledge – into three types: common knowledge (shared by most members of a community, such as how to prepare a local staple food), shared knowledge (known by many but not all, such as basic animal husbandry among livestock-raising families), and specialized knowledge (held by a few, such as the skills of a traditional healer or midwife). Local knowledge is passed down through generations, tested over centuries, and deeply tied to specific environments, cultural practices, and lived experiences.
Both forms of knowledge are valuable and should be treated as complementary rather than hierarchical. A knowledge-rich curriculum, as advocated in contemporary curriculum research, recognizes that equitable education must connect global knowledge with local relevance – helping learners see how universal principles apply to their own contexts while also honoring the wisdom embedded in their communities.
School knowledge vs. non-school knowledge
School knowledge refers to the formally structured learning delivered through educational institutions – organized by curricula, textbooks, syllabi, and assessed through periodic examinations. The Core Knowledge Foundation describes it as an enabling core of broadly shared knowledge that builds strong foundations for later learning and opens doors to effective participation in wider society. School knowledge is systematic, sequenced, and validated by academic and institutional authority. It is organized to be coherent across grade levels, subjects, and learning progressions.
Non-school knowledge – sometimes called experiential or everyday knowledge – is what individuals acquire outside formal settings: through family life, community participation, personal observation, and cultural immersion. As Hoadley’s work in Pedagogy in Poverty describes, everyday knowledge is informal, context-specific, and practically oriented – shaped by personal experiences, family traditions, and community interactions. A child who grows up in a farming household learns about seasons, soil, and crop cycles in ways no textbook can fully capture. A child raised in a fishing community carries deep knowledge about tides, weather, and water – all acquired well before any formal schooling.
The challenge for educators is not to dismiss one in favor of the other, but to bridge them. Research published in Developing Curriculum for Deep Thinking (Springer, 2025) argues that a knowledge-rich curriculum is one of the most powerful levers for achieving equitable learning – particularly when it connects structured school content with the contexts students already inhabit. Cognitive science confirms that new learning builds on existing knowledge: students who arrive with rich prior experiences learn more effectively when teachers acknowledge and connect to what they already know.
Why these distinctions matter for teaching and learning
Understanding these facets is not just an academic exercise – it has direct implications for how teachers plan lessons, design assessments, and engage students. A classroom that only privileges concrete and theoretical knowledge risks producing learners who can recall facts but struggle to apply them. A curriculum that ignores local knowledge in favor of universal knowledge alone risks alienating students from their own identities and lived realities. And an education system that undervalues non-school knowledge misses the rich reservoir of prior understanding students bring to every classroom.
The four facets – abstract and concrete, theoretical and practical, universal and local, school and non-school – are not opposing poles to choose between. They are complementary dimensions of a full and holistic understanding of knowledge. As Learning A-Z’s research on knowledge-based learning notes, the most effective educators begin by understanding what students already know and then use that as a foundation to build richer, deeper, and more connected understanding. When teachers consciously navigate all these facets, they move from simply delivering information to genuinely building knowledge – and that is where real learning begins.
What do you think? How often do teachers in your experience draw on students’ local or non-school knowledge to enrich classroom learning – and what might change in education if this became a deliberate, consistent practice? Do you think theoretical knowledge is given too much emphasis over practical knowledge in today’s curriculum, or does the balance seem right to you?
