“I’m fine with that.”
It is one of the most common phrases I hear as a tutor. Sometimes it’s true. Sometimes it’s not.
Most teachers and tutors will recognise the phenomenon immediately. A student looks at a piece of information and experiences a powerful feeling of familiarity. They’ve seen it before. They recognise the terminology. The explanation seems clear. The worked example makes perfect sense. Everything feels comfortable. Then they attempt a question on their own and discover that they have absolutely no idea what they are doing.
The experience is so common that educational psychologists have spent decades trying to understand it. Why do students so often believe they understand something when they do not? The answer is both fascinating and counter-intuitive.
One of the most important discoveries in modern cognitive science is that the feeling of learning and the reality of learning are not the same thing. This may sound obvious, yet it runs contrary to much of our intuition. We tend to assume that if something feels easy, we are learning it effectively. Conversely, if something feels difficult, we assume that learning is not taking place. In reality, the opposite is often true.
Psychologists refer to this phenomenon as an “illusion of competence”. Students mistake familiarity for understanding and fluency for mastery. Because information feels familiar, they assume it has been learned.
A classic example is rereading. Faced with an upcoming examination, many students return repeatedly to the same textbook chapter or revision guide. The first reading feels difficult. The second feels easier. By the third or fourth reading, the material begins to feel hugely familiar. At this point, many students conclude that they know the material. The problem is that recognising information is not the same thing as being able to retrieve it independently. The latter is what students need to practise.
Anyone who has ever found themselves singing along confidently to a song only to forget the next line when the music stops has experienced the distinction. Recognition is much easier than genuine recall. The textbook provides constant prompts and cues. An examination paper does not.
The distinction was explored extensively by the cognitive psychologists Robert and Elizabeth Bjork, whose work has profoundly influenced modern thinking about learning. They argued that students often confuse current performance with long-term learning. In other words, they judge their understanding based on how things feel in the moment rather than on what they will be able to remember later.
Highlighting provides another excellent example of something which students often over-estimate as a learning tool. I have nothing against highlighting per se, indeed I use it as a methodology in presenting set texts. Colour-coding is useful for organisation and can be an effective way to draw links. Yet the process of using a highlighter creates an illusion of productivity, when in actual fact the student is learning far less than they imagine. A page covered in fluorescent yellow marks certainly looks as though something important has happened. Unfortunately, the evidence suggests that highlighting alone does virtually nothing to improve long-term retention.
Similarly, students frequently spend hours producing beautifully organised revision materials. Their notes are often immaculate. The handwriting is exemplary, different colours have been deployed with military precision and the result resembles a work of art. Yet, if the process has been done as a reference and copy exercise, very little useful learning will have taken place. Such activities feel productive and can even create a real sense of engagement: the brain remains busy and the student remains occupied. Yet much of the cognitive work required for durable learning is missing.
What, then, does effective learning feel like? This, I’m afraid, is where things become particularly inconvenient. According to a substantial body of research, some of the most effective learning strategies feel harder, not easier, than the methodologies reviewed above. Retrieving information from memory, answering questions without notes, explaining concepts in your own words and attempting problems independently all require considerably more effort than rereading or highlighting.
This idea was popularised by researchers such as Henry Roediger and Jeffrey Karpicke, whose work on retrieval practice demonstrated that actively recalling information produces stronger long-term retention than repeatedly reviewing it. Put simply, testing yourself is more effective than studying.
Students rarely enjoy hearing this. If given the choice between reading notes for the fifth time and completing a challenging retrieval exercise, many will choose the former. It feels more successful and it does not put them in the deeply uncomfortable position of being forced to attempt to recall something they currently feel inadequately on top of. The problem is that such feelings are not reliable indicators of learning.
The psychologist Daniel Kahneman described two broad modes of thinking. One is fast, intuitive and effortless. The other is slower, more deliberate and more demanding. Effective learning often requires us to engage this second system, but unfortunately, the intense effort required can easily be mistaken for failure. I see this repeatedly when students begin using retrieval practice for the first time: they become frustrated by the failure rate, since they cannot remember everything immediately. Their conclusion is often that the method is not working when in fact it is the best and only route to success. The struggle is precisely the point. Every successful act of retrieval, however minor, strengthens the memory. Likewise, every failed attempt identifies a gap in knowledge. Both outcomes are useful. The process feels horrendously difficult at first, because the brain is being asked to do genuine cognitive work. And our brains are evolved to choose the path of least resistance, in the same way that we have evolved to take as many opportunities to rest and relax as possible. In the modern world we have built for ourselves, this evolutionary tendency works against us.
The educational psychologist Robert Bjork introduced the concept of “desirable difficulties” to describe this phenomenon. Certain challenges make learning feel harder in the short term while improving retention in the long term. Spacing out revision, mixing different topics together and retrieving information from memory all fall into this category. Once again, it can feel counter-intuitive to mix up revision topics. Won’t I get confused? Answer, no: by switching topics you are giving your brain time to forget what you’ve just learned, then challenging it to recall the same information again when you return to it. This is crucial to the learning process. The difficulty is desirable because it produces stronger learning.
Unfortunately, students are not the only people susceptible to the illusion that ease of process is a good proxy for learning. Teachers can fall victim to this hallucination as well. A lesson in which students nod enthusiastically, answer guided questions correctly and appear fully engaged can create a powerful impression of success for the teacher. Yet genuine understanding may not be demonstrated days or weeks later, when students attempt to apply their knowledge independently.
Parents are vulnerable too. Watching a child spend three hours revising comfortably and calmly can feel immensely reassuring. Yet the quantity of revision and the quality of revision are not necessarily the same thing. Effective studying often looks rather strange from the outside. Students engaged in genuine retrieval practice may spend long periods staring into space, scribbling incomplete answers, making mistakes and struggling to remember information. It looks less impressive than a beautifully highlighted revision guide or a perfectly copied set of notes. Yet it is far more effective.
Forgetting itself plays a role in the process. As I have explored in many previous posts, memory is not a camcorder. Learning requires us to retrieve and reconstruct information repeatedly over time. Some forgetting is inevitable and even useful, because it creates opportunities for the retrieval that strengthens memory.
Perhaps the most important lesson from cognitive science is that knowing something and feeling as though you know something are not the same thing. The human brain is remarkably good at creating an illusion of understanding. We mistake familiarity for mastery, recognition for recall and activity for progress. The challenge for teachers, tutors and students alike is learning to distrust those feelings. Real learning is often slower, messier and more uncomfortable than we would like.
