Short answer first: the techniques that work force you to process the material, not just record it. The Cornell method, the outline method, mind maps, questions in the margin, and the recall test. Preserve exact details when needed, but add explanation, questions and later practice rather than stopping at capture or highlighting.
Note-taking gets treated as a mechanical task: listen, write, done. But if your notes sit unread in a folder and you still feel lost before an exam, the method matters as much as the effort.
The goal of notes is not to create a backup copy of the lecture. It is to help your brain process, encode, and later retrieve information. Some techniques do this well. A format is useful only if it serves the material and how you will use it. And if you were counting on the university's own recording as the backup, check before you rely on it, because lecture-capture availability varies across Irish modules.
Why are verbatim notes a trap?
Before getting into what works, it is worth understanding the most common mistake: writing down everything the speaker says.
There is a useful difference between a transcript and notes. A transcript preserves wording; a note selects and connects information. If keeping up with every word prevents you following the explanation, capture a smaller set of key points and mark gaps to revisit.
What the laptop studies found
The best known evidence is Mueller and Oppenheimer's 2014 study. Students who typed their notes wrote far more words, copied more of the lecture verbatim, and did worse on conceptual questions than students who wrote by hand. The finding became "put the laptop away", which is not quite what it showed. When Morehead, Dunlosky and Rawson repeated the experiment in 2019, the handwriting advantage did not hold up reliably. The replication does not establish that paraphrasing makes the device irrelevant. Consider accessibility, formulas, diagrams and how you will review the notes, rather than treating a single study as a rule for everyone.
Verbatim notes also create a false sense of security. Reviewing pages of dense text before an exam is slow, boring, and does not test whether you actually understand the material. It just re-exposes you to it, which is not the same thing.
1. The Cornell method
The Cornell method was developed at Cornell University and the university still teaches it. It divides a page into three sections. The right side (the largest) is for capturing notes during the lecture. The left column is for keywords and questions, which you fill in after class. The bottom section is for a brief summary in your own words.
The structure forces active engagement twice: once during the lecture and once during review. The question column is especially valuable because it turns your notes into a study tool. You can cover the right side and test yourself from the questions alone.
Cornell works well for lectures with a clear linear structure, like science, economics, or history.
2. The outline method
This is the most intuitive approach for structured content. Main topics become top-level headings, subtopics indent below them, and supporting details indent further. The hierarchy reflects the logic of the subject.
The outline method keeps your notes organised in real time and is easy to scan afterwards. It works best when the speaker follows a predictable structure or when you are taking notes from a textbook.
Where it falls short is with creative, conceptual, or interdisciplinary content that does not have a natural hierarchy.
3. Mind mapping
A mind map starts with the central concept in the middle of the page and branches outward into related ideas, connections, and details. It is a visual and spatial format rather than a linear one.
Mind maps work well for brainstorming, revision, and subjects where relationships between ideas matter (psychology, biology, literature, business). They are harder to create during fast-paced lectures but excellent for reviewing and consolidating information afterwards.
One caution from the research: drawing the map is not the same as learning it. In a 2011 experiment, students who built concept maps while studying remembered less a week later than students who spent the same time on a recall test, even on questions that needed inference. Draw the map, then close it and redraw it from memory. Compare the second drawing with the source so missing or incorrect relationships become visible.
If you find linear formats stifling, or if you are the kind of person who thinks in connections rather than sequences, mind mapping is worth trying.
4. Questions in the margin
This technique is compatible with any note-taking style. As you write notes, you add questions in the margin whenever something is unclear, seems important, or makes you curious. After class, you resolve those questions through your textbook, readings, or a quick follow-up with the instructor.
Unanswered questions are often where the real learning happens. They push you to engage with the material rather than accept a summary of it.
5. The recall test
This is less a format and more a practice. After taking notes in any style, you close them and write down everything you can remember from the lecture. No peeking.
What you recall independently is useful evidence of current understanding. A missed answer is a prompt to investigate: you may need a cue, a clearer explanation or more practice. The technique has a name, active recall, and spreading those reviews over the following days is spaced repetition. Start with a small question set and leave time to check the answers; the benefit is not guaranteed by a particular session length.
Which technique for which subject?
| Technique | Useful starting point | When it happens | Follow-up task |
|---|---|---|---|
| Cornell | Topics suited to question-and-answer review | During and after | Add cues, check the summary and answer questions |
| Outline | Lectures with a clear structure, textbooks | During | Check the hierarchy and missing links |
| Mind map | Relationships between concepts | Mostly after | Explain and verify each connection |
| Margin questions | Unclear claims or steps | During and after | Resolve the question using the source or tutor |
| Recall test | Retrieving explanations, facts or methods | After | Check errors and attempt again later |
A practical combination is one format for the room and the recall test after it. Which app you run either of them in is a separate decision, compared tool by tool in the best note-taking app for students.
Which habits should you drop?
Transcribing everything. As mentioned above, unselective capture can crowd out attention to the explanation. If you find yourself typing faster than you can think, you are transcribing rather than learning. Slow down and paraphrase.
Highlighting without processing. Highlighting can help locate material, but it does not itself test recall. Colourful marks on a page do not tell you whether you actually understand the content or can recall it under pressure. The 2013 review of ten study techniques rated highlighting and rereading as low utility across the board, and self-testing as the technique with the strongest evidence. If you highlight, follow it immediately with a question or paraphrase in the margin.
A weekly routine that fits any of the five
- In the lecture. Use one format from the list and capture the important details without a fixed word quota.
- Same day, 15 minutes. Turn the page into five to ten questions (the Cornell cue column does this for you).
- Two days later, 10 minutes. Answer the questions from memory. Mark the misses.
- Weekend, 20 minutes per subject. Blank page recall of the week, then compare against the notes.
These are example time slots; the total depends on how many lectures you have and how much explanation or practice you need. If the hour keeps going on typing rather than thinking, the tooling is the thing to change, and the best note-taking app for students is where that choice is laid out.
The bigger picture
Good note-taking is a thinking skill, not just a writing one. The format you choose matters less than whether it forces you to process the material actively and test your own recall. The room matters as well, and tutorials and labs may require different notes from a lecture.
Where recording and processing are permitted, Notibo can draft a transcript and structured notes. Check terminology, omissions and examples against the course material, then add your own questions. AI capture is a starting point for review, not proof that the explanation is accurate.
