How to Take Better Notes During Online Classes

Your Notes Look Full, But You Can't Explain Any of It

You had your laptop open the whole class. You typed constantly, filling page after page.

Later that night, you open those notes to study, and none of it makes sense. It reads like a transcript, not something you actually understood while it was being said.

Online classes have a specific way of making this worse than a regular lecture hall ever did. The screen sits an arm's length from a dozen other tabs, notifications, and the general pull of being anywhere except fully present in the lecture.

A few reasons online note-taking goes wrong so often:

• Typing makes it easy to write down everything word for word, which feels thorough but skips the mental processing that actually helps you learn.
• The same device running your class is also running everything else, so a notification or open tab is one click away from pulling your attention out of the lecture entirely.
• Online classes rarely force eye contact or accountability, making it easier to drift into passive listening while your hands keep moving on autopilot.
• Nobody teaches note-taking specifically for a remote setup, so most students just carry over habits built for an in-person classroom that don't quite fit.

The cost of notes that don't actually work shows up clearly at review time.

• Rereading a wall of verbatim typed notes takes far longer and teaches far less than reviewing notes that were actually processed while being written.
• Realizing your notes don't make sense right before an exam adds stress on top of whatever material already feels difficult.
• Passive note-taking during class means less material gets encoded into memory in the first place, so more relearning is needed later.
• The frustration of "I was there the whole time, why don't I remember this" chips away at confidence in your own ability to focus.

Here's the useful starting point. According to a summary from Washington University in St. Louis's Center for Teaching and Learning, citing a widely cited study by researchers Pam Mueller and Daniel Oppenheimer, students who typed their notes tended to transcribe lectures word for word, while students writing by hand had to summarize and process information as they went, since handwriting is slower. That extra processing step during handwriting, not the speed of getting words down, is what tends to produce stronger learning.

Building a Note-Taking System That Works for a Screen

Consider handwriting your notes even during an online class, especially for concept-heavy material. Since typing invites verbatim transcription, switching to a notebook forces you to condense and process each point instead of racing to capture every word. You can always type up a cleaner version afterward if you want a digital copy.

Use a structured format instead of a plain running list. The Cornell Note-Taking System, developed at Cornell University and still actively taught through the university's Learning Strategies Center for both in-person and remote learning, divides a page into a narrow question column, a larger note-taking area, and a summary section at the bottom. During class, you record notes in the main area. After class, you write questions in the side column and a short summary at the bottom, which turns passive notes into something you can quiz yourself with later.

Picture the difference this makes. One student's online class notes are a single unbroken block of typed text with no structure, indistinguishable months later from any other day's notes. Another student's notes, using a Cornell-style layout, include a short list of self-testing questions in the margin and a two-sentence summary at the bottom of each page. When exam time comes, the second student can quiz themselves directly from their own notes instead of rereading everything from scratch.

Physically separate your note-taking space from your distraction space. If you're typing notes, keep the lecture window and your notes document as the only two things open, closing everything else, including browser tabs unrelated to class. If you're handwriting, keep your phone out of arm's reach during the session. The goal is removing the one-click path from "taking notes" to "checking something else."

Leave visible gaps for anything you miss. Online audio and connection issues happen more often than in a physical classroom. Leaving a blank line or a marked gap when you lose the thread lets you fill it in from a recording or a classmate afterward, rather than losing the flow of your notes trying to catch up in real time.

Write a short summary in your own words within a few hours of class, not days later. According to the same Cornell method, summarizing shortly after the lecture, while the material is still fresh, is what turns notes from a passive record into something that actually helped you learn the content the first time. Waiting too long to do this summary defeats much of the purpose.

Quick Comparison: Passive vs. Structured Online Notes

Passive Typed Notes	Structured Online Notes
Word-for-word transcription	Condensed, processed summaries
No built-in review questions	Cue column with self-test questions
Reviewed by rereading everything	Reviewed by quizzing from cue column
Distractions one click away	Notes app or notebook kept as the only open window

None of this requires new software or a complicated setup. It mostly means slowing down enough during class to actually process what's being said, rather than racing to capture every word a screen happens to be delivering.

Taking Notes That Work With How Online Lectures Are Built

Online classes come with a specific challenge in-person lectures don't: slides, narration, and sometimes on-screen text all competing for your attention at once. A few adjustments make note-taking work with that setup instead of against it.

Don't copy slide text you already have access to. Many online classes post slides separately or leave them visible on screen throughout the lecture. According to research on the Cognitive Theory of Multimedia Learning developed by UC Santa Barbara psychology professor Richard Mayer, people learn more deeply from a combination of words and visuals than from either alone, but only when the material is presented in a way that avoids overloading attention. Retyping text that's already sitting on the screen adds nothing, and it uses up mental effort that could go toward actually following the explanation.

Focus your notes on the connections and explanations, not the visible facts. If a slide already lists three causes of a historical event, your notes don't need to repeat that list. They're more useful capturing what the instructor says about why those causes mattered or how they relate to each other, the part that won't be sitting in a downloadable file after class.

Compare notes with a classmate soon after the lecture. According to reporting from Vanderbilt University's Center for Teaching, collaborative note-taking is one of the active learning strategies instructors have leaned on specifically for hybrid and online classes, since comparing notes with another student naturally surfaces gaps and different interpretations neither person caught alone. Even a ten-minute message exchange with a classmate after class can catch something you missed.

Here's a way to picture this in practice. Two students attend the same online statistics lecture, slides included. One spends the class typing out every formula shown on screen, which are already saved in the posted slide deck. The other spends that same time jotting down the professor's explanation of when to use each formula and why, information that exists nowhere except in their own notes. When exam time comes, the second student has something the slides never gave them.

Use the recording as a backup, not a replacement for active note-taking. It's tempting to relax during class since "I can just rewatch it later." In practice, rewatching an entire lecture takes far longer than reviewing notes taken the first time, and most students never actually go back and rewatch the full session. Treat the recording as insurance for the specific moments you miss, not your primary study method.

Review your notes within a day, using them to test yourself rather than just rereading. Notes taken during an online class are only the first step. Our guide on what active recall is and why it improves memory explains how closing your notes and testing what you remember turns a passive record into something that actually builds long-term memory, which matters even more for online classes where it's easier to have been only half-present during the lecture itself.

For long-term consistency, build a short review habit right after each online class becomes a routine, not an occasional effort. If you want to space that review out further so the material sticks for exams weeks away, our guide on what spaced repetition is and how it helps learning shows how to schedule that follow-up review effectively.

Habits That Quietly Undermine Online Note-Taking

A handful of common patterns specific to the online format tend to sabotage note-taking without students noticing right away.

Keeping the chat window or a second monitor open "just in case." Even a class-related chat window competes for attention. Every glance away from the lecture, even a brief one, breaks the flow of following and processing what's being explained.

Treating slide downloads as a substitute for personal notes. Slides capture what the instructor planned to say, not the explanations, examples, or answers to classmate questions that happen live. Relying only on the posted slides leaves a real gap in what you actually understood.

Never testing whether your notes make sense without the recording playing. Notes that only make sense while you're rewatching the lecture that produced them aren't doing their job. If you can't follow your own notes days later without the video, they need more structure or more of your own explanation added.

Multitasking during the live session and planning to "catch up" from the recording. This usually means paying full attention to neither the live class nor the eventual rewatch, since rewatching an entire lecture rarely actually happens once the day gets busy again.

Letting inconsistent internet or audio issues create permanent gaps. A missed few minutes during a spotty connection can turn into a permanent hole in your notes if it's never addressed. Flagging the gap and asking a classmate or checking the recording for just that section closes it before it becomes a bigger problem at exam time.

A Quick Question and Answer

Q: What if my class doesn't record lectures at all? A: Treat every live session as your only chance to capture the material, which makes active, structured notes even more important than in a recorded class.

Q: What if I already have months of messy online class notes from earlier this semester? A: You don't need to redo all of them. Start applying a better system to new material going forward, and revisit older notes only for the specific topics still coming up on upcoming exams.

Notes You'll Actually Want to Open Again

The point of taking notes was never to prove you were present for the lecture.

It's to leave yourself something worth opening again, something that actually helps when you sit down to study weeks later.

Try one change from this guide in your very next online class: closing an extra tab, switching to a structured format, or reviewing what you wrote within a day instead of waiting until the night before the exam.

Notice whether your notes from that one class feel more useful than your usual ones. If they do, keep the habit going. Good online class notes aren't about writing more. They're about writing the kind of notes your future self will actually be glad to find.
