Teaching Peers with Different Levels of Knowledge

Explaining something well doesn’t mean repeating what the book says in different words. It means reading the person in front of you: what they know, what they’re missing, and which example will click in their head. When you study in a group, almost everyone moves at a different pace, and if you explain the same way to someone who already masters the topic as to someone who’s lost, you lose both. Here’s how to adjust your explanation based on who’s listening, without condescension and without unnecessary jargon.

Why the same explanation doesn’t work for everyone

Each classmate arrives at the topic with a different mental map. One already connects the new concept to something they studied before; another starts from zero and needs an anchor point. Pedagogical adaptation is exactly that: identifying the map the other person has before you start drawing on top of it. If you assume a level that doesn’t exist, your explanation sounds like a foreign language, even if you use familiar words.

This isn’t a “good teacher” whim. It’s rooted in how memory works: new information is retained better when it’s linked to something we already know. Explaining without that prior connection is like asking someone to memorize a phone number without context: it goes in and out without leaving a trace.

The first step: diagnose before you speak

Before diving into an explanation, spend thirty seconds asking. You don’t need a formal test, something like this is enough: “what do you already have clear about this?” or “where did you get stuck?”. The answers give you extremely valuable information about where to start.

• If the person repeats definitions by memory but doesn’t know how to apply them, the problem isn’t knowledge but practice.
• If they confuse related concepts, you need to mark the differences before moving forward.
• If they don’t even recognize basic vocabulary, you need to drop a level lower than you thought.

This quick diagnosis avoids the most common mistake when teaching different levels: starting halfway through the explanation assuming a foundation that doesn’t exist.

How to teach someone who knows less than you without sounding like a manual

When the other person starts from a lower base, the temptation is to simplify so much that the explanation loses substance. The key isn’t removing content, but changing the order and the support. Always start with the concrete and move up to the abstract, never the other way around.

• Use an everyday example before naming the technical concept.
• Avoid introducing two new ideas in the same sentence.
• Ask “does this make sense so far?” every two or three steps, not at the end.
• Let the person repeat the idea in their own words before moving on.

This last point connects directly with the idea of explaining in your own words instead of repeating from memory: if your classmate can only repeat what you said literally, they haven’t understood it yet, they’ve only memorized it.

How to keep the interest of someone who knows more than you think

The opposite mistake also exists: treating as a beginner someone who only needs a specific push. If you repeat the basics to someone who already masters them, they disconnect quickly, and on top of that they may feel underestimated.

With this profile, jump straight to the point where they have the real doubt. Ask them exactly which part doesn’t click and work only there. Take the opportunity to ask questions that force them to apply the concept in a new context, not just repeat it. This keeps the level of demand high and prevents the session from feeling like a waste of time for either of you.

Adapting the explanation when there are several levels in the same group

Teaching different levels at once, within a small group, requires a different strategy. You can’t personalize every sentence for every person, but you can structure the explanation in layers: a common base for everyone, followed by deeper questions for those who are more advanced.

• Start with the general explanation, using a simple example everyone can follow.
• Then, ask a more complex question and let whoever is more advanced answer first.
• Ask those who already understood to rephrase the idea for the rest: this reinforces their own learning and helps the group.

This dynamic works especially well when preparing mini-lessons for your study group classmates, where you can anticipate the different levels before the session and plan staggered content blocks.

Choosing the right example depending on who’s listening

The same concept can be explained with completely different examples depending on the person. If your classmate plays a lot of video games, a probability example based on loot boxes will click more than one about cards. If they’re passionate about sports, statistics from a game could be the perfect hook.

This isn’t simplifying the content, it’s translating it into a language the other person already masters. The closer the example is to their daily experience, the less mental effort they need to make the leap between the known and the new.

What to do when you notice the explanation isn’t working

Sometimes you adapt the explanation as you thought was right and still see a confused face. The clearest signal is prolonged silence or vague answers like “yes, more or less”. At that moment, stop and change strategy instead of continuing on autopilot.

• Change the example for a completely different one, not a variation of the same one.
• Ask the person to draw or write down what they’ve understood so far.
• Break the idea into smaller parts and confirm each one separately.

Detecting this blocking point is also useful for you: you often discover your own understanding of the topic had a gap you hadn’t noticed until you tried to explain it.

The balance between simplifying and not losing rigor

Adapting the level doesn’t mean lying with simplifications that will later need correcting. You can lower the complexity of the language without sacrificing the accuracy of the idea. The difference lies in the depth of the details, not in the truthfulness of the content.

A good test is to ask yourself: “would what I’m saying still be true if the person went deeper later on?”. If the answer is yes, you’re doing fine. If you’d have to contradict something you said before, you’ve oversimplified.

Frequently asked questions

How do I know if I’m explaining too basic or too advanced?

The other person’s reaction gives you the answer. If they nod quickly without asking questions or disconnect, you’re probably going too basic. If they frown, ask you to repeat, or answer with very general phrases, you’re going too advanced. Ask directly every few minutes to adjust the pace in real time instead of waiting until the end of the explanation.

What do I do if my classmate feels bad for not understanding something obvious to me?

Normalize the situation by saying something like it was hard for you too at first, without dramatizing the comment. Avoid phrases that sound surprised by their lack of knowledge. Focus on the content, not on the fact that they didn’t know it, and quickly move on to showing them the way to understand it.

Is it better to adapt the explanation to each person or give a standard explanation for everyone?

It depends on the context. In a one-on-one session, adapting always gives better results because you can adjust the pace and examples. In a group with mixed levels, a common base followed by differentiated deep-dive questions works better, so you don’t leave anyone completely out or bore whoever knows more.

How much time should I spend diagnosing the level before starting to explain?

With a couple of well-chosen questions, thirty seconds or a minute is usually enough to get a clear idea of where to start. You don’t need a formal questionnaire, just listen carefully to the other person’s first answer about what they already know on the topic.

What do I do if I don’t fully master the topic I’m asked to explain at a more advanced level?

Be honest instead of improvising an unreliable answer. You can say you’ll review it and come back with a more solid answer, or suggest researching it together right then. Faking full mastery is usually noticeable and can also spread incorrect information that’s later hard to correct.
