Lecture #11: Taking notes effectively - which words should you write down?

Most advice on note-taking assumes the goal is to create a perfect transcript. Jeffrey Kaplan dismantles this myth immediately, arguing that the very act of writing down every word is the primary reason students fail to learn. His thesis is counterintuitive but backed by a mountain of cognitive science: efficiency in learning comes not from speed, but from the friction of summarizing ideas in real-time.

The Myth of the Transcript

Kaplan opens by rejecting the standard approach where students attempt to capture the lecture verbatim. "People think that when you take notes, you're supposed to write down the stuff that you hear. No," he writes. This distinction is crucial because it shifts the cognitive load from a mechanical task to an analytical one. The author argues that words are merely symbols; without processing their meaning, a student ends up with a "transcript of the words" but zero retention.

Lecture #11:  Taking notes effectively - which words should you write down?

The core of Kaplan's argument is that effective note-taking requires active engagement. He suggests that students should listen to a full concept, process it, and then write a summary in their own words. "If they talk for a minute... Write down that minute of talking in your own words in five words," he advises. This forces the brain to synthesize information rather than just store it. Critics might note that this method requires a level of prior knowledge or confidence that struggling students may lack, potentially causing them to write nothing at all if they feel they don't understand the material immediately.

"You have to think through the meaning of what you're hearing. You have to engage with the content of what you're hearing and then write down a summary of that content in your own words."

The Critical 24-Hour Window

Kaplan introduces a second, often overlooked phase of the process: the review. He describes initial notes as merely the "bones" of the creature, requiring "flesh" to become useful. This flesh must be added within 24 hours. "Because you're doing this within 24 hours, there'll be all these memories that will be that will be pulled up in your mind," he explains. The urgency here is biological; the author contends that the specific context and fleeting associations formed during the lecture evaporate quickly.

He admits that this step is time-consuming and that "many students won't do this part," expressing a palpable frustration that learners are willing to sacrifice long-term retention for short-term convenience. "It will increase your powers dramatically," he insists, framing the extra ten minutes not as busywork, but as the difference between a skeletal outline and a robust study tool. This framing is effective because it treats memory as a perishable resource that must be harvested immediately.

The Digital Distraction

Perhaps the most contentious part of Kaplan's lecture is his absolute rejection of digital devices for note-taking. He cites a 2016 study showing that "average final exam scores among students assigned to classrooms that allowed computers were 18% of a standard deviation lower than exam scores of students in classrooms that prohibited computers." The argument extends beyond simple distraction; even when students attempt to use laptops solely for note-taking, the speed of typing encourages verbatim transcription, which leads to "shallower processing."

Kaplan does not mince words regarding the human capacity for self-control in the digital age. "Who do you think you are? Are you kidding me?" he asks, noting that even faculty members succumb to the temptation of checking emails or browsing the web during meetings. He highlights a 2013 study revealing that merely sitting near a peer who is multitasking on a laptop can lower one's own test scores. "Divided attention reduced long-term retention of the classroom lecture," he summarizes, citing a 2018 paper. While the science on the "multitasking peer" effect is compelling, some educational researchers argue that digital tools can offer accessibility benefits for students with specific learning disabilities, a nuance Kaplan largely dismisses as an exception rather than the rule.

"Even when laptops are used solely to take notes, they may still be impairing learning because their use results in shallower processing."

Bottom Line

Kaplan's strongest contribution is reframing note-taking from a recording exercise to a cognitive processing tool, supported by robust data on the downsides of digital transcription. However, his rigid stance on handwriting ignores the practical realities of modern accessibility and the potential for digital organization tools to aid the "fleshing out" phase he champions. For the busy professional or student, the takeaway is clear: the friction of writing by hand is not a bug, it is the feature that drives learning.

Lecture #11: Taking notes effectively - which words should you write down?

by Jeffrey Kaplan · Jeffrey Kaplan · Watch video

People think that when you take notes, you're supposed to write down the stuff that you hear. No. To take notes properly, you need to do four things. One, never write down every word.

Two, don't even grab whole phrases and write those down exactly. Three, add flesh onto your notes within 24 hours. I'll explain what that means later in the video. And four, take notes by hand using a pen or a pencil, not by typing.

Over the course of this lecture video that you're watching right now, I'm going to go through all four of these techniques for taking notes properly. And if you take notes properly, then two things will happen. There will be two benefits. Here they are.

The first benefit is that during that one hour of lecture or however long it is during that period of time you will absorb more information into your brain. So you'll just leave remembering much more of what you just heard. The second benefit is that you'll have the notes. You'll still have them.

You'll have a written record. your notes which you can look back on later at the end of the semester or years later you'll have those notes. Both of these benefits are matters of efficiency. You're getting more out of that same one hour of lecture.

You're absorbing and retaining more information and you're getting this physical product, these notes that you can use later. They'll be very useful later. you're just getting them. But in order to get these benefits, you have to take notes properly.

And the main thing about taking notes properly is that you can't just write down word for word what you hear or just grab phrases here or there. You have to think through the meaning of what you're hearing. You have to engage with the content of what you're hearing and then write down a summary of that content in your own words. You have to do it that way or else you won't get this stuff.

I'm going to explain how to do that. Here we go. Fundamentally, taking notes is a tool of efficiency. You're going to be in class for that period of time anyway, right?

You're there in the room anyway. How can you use that same amount of time, that same 1 hour of lecture or 1 hour and 15 minutes ...
