Walk into any university library in Australia and you’ll see the same scene, students hunched over textbooks, highlighters in hand, painting pages in neon yellow and pink. They feel productive. They look busy. But research shows that highlighting is one of the most ineffective study methods available. The problem isn’t the highlighter itself. The problem is what happens in your brain when you use it.
The Recognition Trap
Highlighting creates what psychologists call an “illusion of knowledge.” You recognise the highlighted text when you see it again. Your brain thinks, “Yes, I know this.” However, recognition and recall are completely different cognitive processes. To clarify, recognition is what happens when you see a highlighted passage and think you understand it. In contrast, recall is what happens during an exam when you need to retrieve that information from memory with no prompts.
This distinction matters enormously in Australian education contexts. Whether you’re sitting for the HSC in New South Wales, the VCE in Victoria, or university exams at any institution, examiners test recall, not recognition. They’re not asking you to identify which passage looks familiar. They’re demanding you produce knowledge independently. For example, students who highlighted material felt confident going into tests. Nevertheless, they couldn’t actually retrieve the information when tested unprompted.
Moreover, one study found that underlying material actually reduces your ability to draw inferences. Consequently, you’re not just wasting time. You’re potentially hurting your comprehension. Furthermore, the data gets worse. Students who relied heavily on highlighting spent more time studying but performed worse on application questions. Specifically, they could recognise facts but couldn’t use them to solve problems or analyse scenarios, exactly the skills Australian universities and employers value most.
What Actually Works, Active Recall
The science is clear on this point. A landmark 2013 meta-analysis by Dunlosky and colleagues, published in Psychological Science in the Public Interest, evaluated 10 common learning techniques. Their findings were definitive: practice testing (active recall) and distributed practice were rated as having high utility for improving student learning. In contrast, highlighting and underlining were explicitly rated as having low utility, meaning they provide minimal benefit despite being among the most popular study methods. Active recall forces your brain to do the hard work of retrieving information. This retrieval process strengthens neural pathways and creates durable memory. In contrast, highlighting lets you stay passive. Active recall demands engagement. To illustrate: highlighting is like watching someone else exercise, while active recall is doing the workout yourself. Only one builds strength.
The Cornell Method, Active Recall in Practice
The Cornell Method gives you a structured system for building active recall into your note-taking. Here’s how it works: Divide your page into three sections. The right column (about two-thirds of the page) is for notes during lectures or reading. The left column (about one-third) is for questions and keywords. The bottom section is for summaries. During class or reading, take notes in the right column. Don’t try to write everything. Focus on main ideas and supporting details.
After class, review your notes and create questions in the left column. These questions should prompt you to recall the information in the right column. At the end, write a summary at the bottom. This forces you to synthesise the material. Essentially, the method works because it operates at multiple cognitive levels: you’re capturing information like a stenographer, analysing it like a lawyer, and synthesising it like a researcher.
Significantly, this multi-layered approach mirrors how professionals actually work in Australian industries. For instance, teachers plan lessons, then reflect on effectiveness. Similarly, engineers design solutions, then document decision-making. Ultimately, the Cornell Method teaches you to think like an expert, not just memorise like a student. Research on note-taking by Mueller and Oppenheimer (2014) demonstrated that students who synthesised information by taking summary notes rather than transcribing verbatim showed deeper conceptual understanding and better long-term retention.
How to Start Using Active Recall Tomorrow
You don’t need to overhaul your entire study system overnight. First, start with one subject. Next, set up your notes using the Cornell Method format. Then, after your next lecture, spend 10 minutes creating questions in the left column. The following day, cover the right column and try to answer your questions from memory. This is active recall in action. Initially, you’ll probably struggle. That struggle is the point where your brain is working harder, which means it’s learning deeper. As a result, within a few weeks, you’ll notice something: you remember more from lectures without constantly reviewing your notes. Information sticks the first time.
The Bottom Line
Your study habits shape your academic outcomes. Highlighting feels productive because it’s easy and colourful. However, easy rarely equals effective when it comes to learning. On the other hand, active recall feels harder because it is harder. Your brain has to work to retrieve information. Therefore, that work creates the neural connections that help you remember material during exams. In summary, the Cornell Method gives you a practical framework for building active recall into your daily study routine. You’re not just taking notes. You’re creating a tool for learning. Put down the highlighter. Pick up a system that actually works. Your future exam scores will thank you.
