Teaching ≠ Learning

Planning for permanence not performance

Most teachers will recognise the experience of teaching something that appears, in the moment, to have been well received. Students seem engaged, they respond fluently to questions and the lesson feels secure, as though the knowledge has settled. Yet a few weeks later, sometimes only days, it becomes clear that much of it has faded. What felt coherent and obvious in the teacher’s mind bears little resemblance to what remains in the memories of the class.

Teaching is the deliberate act of transferring knowledge from one mind to another, whereas learning is a durable change in long-term memory. The two are connected, but one does not guarantee the other. Learning is not engagement or compliance, nor is it the ability to get something right at the end of a lesson. It is what endures: a lasting change in memory that shapes what a student can later recall, do or understand.

For a long time, I mistook activity for learning. If a lesson was busy, if students were discussing, moving and producing something visible, it felt successful. It looked successful and was often praised as such. Yet visibility and momentum are not reliable indicators of what will remain once the moment has passed. Busy does not mean remembered.

Cognitive science explains what is happening in young learners’ minds, not just what is happening in the room. Working memory is narrow and fleeting, easily overloaded and quick to discard what it cannot process. Long-term memory, by contrast, is expansive and structured. Learning depends on the gradual construction of schema within it, interconnected networks of knowledge that allow new ideas to be understood rather than merely encountered. New information does not settle simply because it has been presented. It has to attach to something already there and secure. Where there is no stable structure for it to connect to, it slips away.

Seen through that lens, the case for explicit instruction becomes less ideological and more practical. When students are novices, clarity is not control; it is efficiency. Careful explanation limits unnecessary cognitive load and increases the likelihood that core knowledge is encoded accurately from the outset. Modelling exposes the thinking that would otherwise remain hidden, while guided practice allows misconceptions to surface while they are still pliable rather than after they have hardened into habit. Independence should not be the starting point. It is the consequence of knowledge sufficiently organised to bear it.

Discovery in the absence of secure knowledge does not produce autonomy. More often, it produces confusion. The limits of working memory do not disappear because an activity is engaging.

Rosenshine’s “Principles of Instruction”, particularly its emphasis on high success rates during practice, makes the point clearly. Learning requires effort, but repeated failure erodes it. Students need success as they are stretched. The teacher’s craft lies in holding that balance so that challenge strengthens learning rather than weakens it.

Bjork’s work adds to our understanding of how we learn. Spacing, interleaving and variation can make learning feel less smooth in the moment, yet strengthen retention over time. What feels fluent is not always secure, with ease during a lesson potentially masking fragility days later.

The same principle extends beyond the individual lesson into curriculum design. Knowledge presented in fragments does not assemble itself. Without deliberate sequencing and revisiting, information remains disconnected. Pace can be mistaken for progress, coverage for understanding. Unless ideas are organised into a coherent structure and returned to repeatedly, they remain brittle.

Educational debates are not settled, nor should they be. Education cannot be reduced to memory alone. Yet across cognitive psychology and classroom research one point is clear: durable learning depends on the accumulation, organisation and retrieval of knowledge in long-term memory. Without that foundation, higher-order thinking has nothing stable to operate on.

If we take that seriously, some classroom practices are simply safer bets than others:

• Sequence content deliberately so new ideas build on secure knowledge rather than sit in isolation

• Make core knowledge explicit and revisit it systematically

• Embed retrieval into everyday classroom routines rather than reserving it for revision

• Introduce new material with clarity, especially for novices, and model the thinking, not just the answer

• Maintain high success rates during guided practice while correcting misconceptions early

• Withdraw scaffolds deliberately as understanding strengthens

• Teach vocabulary explicitly and foreground disciplinary language

• Calibrate challenge so effort strengthens memory rather than overwhelms it

• Space practice over time rather than relying on massed exposure

If we accept what cognitive science tells us about memory, then some teaching methods are simply more likely to work than others.

Teaching can look animated and impressive. Learning is slower and less visible, constructed in the mind and revealed only over time. A lesson may run smoothly, students may answer fluently and pages may fill, yet none of this guarantees that anything has taken root. A classroom can appear industrious while memory remains unchanged.

What counts is what endures once the lesson has faded. The measure is not whether students seemed engaged in the moment, but whether the knowledge is still there weeks later, connected to other ideas and available for use. The difference between performance and learning is rarely obvious in the hour itself. It becomes clear later.

If that is the standard, then planning changes. Sequencing becomes deliberate, explanations precise and practice judged by what it secures rather than how it looks. The work may feel slower and more exacting, but it is how learning compounds over time.
