The Skill of Learning from Lectures

Main Idea

Learning from lectures is not simply a matter of information passing from teacher to student during class. It develops over time through preparation, attentive participation, and review. What students do before and after a lecture may affect their learning as much as—or more than—the lecture’s quality alone.

Lectures remain popular largely because they are economical: one instructor can teach many students. Tradition also plays a role. But a lecture, especially one without interaction or reflection, is not automatically an effective way to learn.

A Three-Stage Approach to Learning from Lectures

1. Prepare Before Class

Having some familiarity with the material makes it easier to follow new ideas and reduces the amount of new information your working memory must handle.

• Do a little relevant preparation. The right approach depends on the subject:
  • For a new math technique, learn what it is, study worked examples, and try a few basic problems—even if you cannot solve them yet.
  • For a history or reading-based class, engage with at least part of the assigned reading rather than rushing through every page.
• Prefer depth to box-checking. If time is limited, read fewer pages carefully. Reflect on the material, take notes, draw diagrams, or visualize the ideas.
• Preview unfamiliar terms and concepts. Recognizing some terminology in advance can make the lecture less overwhelming.
• Build connections. New facts are easier to remember when they fit into a related set of ideas. Preparation gives the lecture something to build on.
• Get practical experience when appropriate. Trying a procedure or problem before class can complement the theory presented in the lecture.
• Start organizing the material. Preparation is the first pass through a topic, the lecture is another, and review helps bring the ideas together.

2. Participate Attentively During Class

Attention is not about looking attentive or recording every word. The goal is to follow the material in a way that supports understanding.

• Reduce distractions, especially phones and unrelated websites.
• If note-taking helps, use it to summarize and synthesize, not transcribe word for word.
• Pay attention to relationships between ideas:
  • Why is a problem solved this way rather than another way?
  • Could it be solved differently?
  • How are two examples different—or fundamentally similar?
  • Does the lecture contradict or differ from the reading?
• Use what you learned during preparation to make the lecture more familiar and easier to follow.
• Expect your attention to fade. The speaker notes that close attention often declines after roughly 10–20 minutes without a change of format or activity. This is not simply a personal failure.

For Online Lectures

• Use the ability to pause, rewind, or adjust playback speed.
• Pause at examples and try to solve or understand the problem before hearing the explanation.
• Stop every 10–15 minutes to organize your thoughts and consider where the lecture is going.
• Avoid watching for too long without a break. The speaker says that beyond about 30 minutes, they personally feel they are getting less from the session.

3. Review After Class

Review is a third pass through the material. It helps consolidate, structure, and extend what you learned.

• Try free recall: Soon after class—ideally within a day—take a blank sheet of paper and write down everything you can remember. Organize it into a summary, then use your notes, readings, the lecture, or other resources to fill in gaps.
• Even doing this once a week can help if you are not otherwise synthesizing the material.
• Other review methods include:
  • Explaining the lecture aloud to yourself.
  • Discussing it with a classmate or someone unfamiliar with the topic.
  • Testing yourself with practice questions.
  • Asking ChatGPT to generate questions from your notes or summary.
  • Writing a short how-to guide for yourself or someone else.
• Explaining ideas to another person can reveal gaps that were not obvious while listening.
• Review may also prepare you for the next lecture, especially when lectures build on the same topic.
• Do not assume the basics are already mastered. Familiar introductory ideas may have been understood only superficially. Strong foundations often make later topics clearer.

Ways to Organize What You Learn

Look for the kinds of structures that matter in a particular discipline. For example:

• General principles and specific cases: Understand both the broad pattern and the examples that illustrate it, including exceptions.
• Claims and evidence: Know what a claim means, what evidence supports it, and how strongly that evidence supports it.
• Methods and tools: Learn both new ways to solve problems and how to use existing tools more effectively.
• Rules and interpretations: In law, connect rules from statutes, regulations, or common law with court decisions and arguments about how those rules apply.
• Parts and systems: In anatomy, learn details while also understanding how they contribute to larger systems and functions.

Review should also connect conceptual ideas from lectures with procedural skills practiced in homework. One approach is to look at homework questions and identify which lecture ideas, tools, or methods apply before trying to solve them.

Practical Takeaway

This approach does not require extensive work before and after every lecture. Even a few minutes of preparation and a brief recall exercise can be useful. Starting early in the semester helps foundational knowledge accumulate, potentially reducing the effort needed later.
