The way you take notes during a lecture directly affects how well you understand and remember the material! Scientists have proven: pen and paper handle this task more effectively than the fastest laptop.
The main problem with digital devices is the typing speed. When a person types at 30–35 words per minute, there is no need to think: it is easier to transcribe a lecture word for word, like a stenogram, than to try to process and rephrase what the lecturer has said. In one experiment, students were specifically asked not to write word for word, but they still fell back into mechanical transcription.
Writing by hand is slower, but this "slowness" is its main advantage. To keep up with the lecturer, the student is forced to filter information and select only the key points, rephrase complex ideas in their own words, and structure the material in real time. This process makes the brain work actively: synthesizing, analyzing, and compressing ideas. It is precisely this cognitive engagement that helps one better absorb the topic.
What does the research say?
- The classic experiment. Scientists Pam Mueller and Daniel Oppenheimer proved back in 2014 that students with laptops write more words but perform worse on comprehension and analysis questions. The difference is especially noticeable in the exact sciences (physics, chemistry, mathematics), where it is difficult to quickly type formulas and diagrams.
- Meta-analysis. A review of 14 studies showed that switching to digital notes reduces the proportion of students with above-average academic performance by approximately 25%.
- Neurobiology. Norwegian scientists using EEG found that handwriting activates far broader neural networks in the brain. This is critically important for encoding new information and retaining it in memory.
