I had a student once who was not getting it. Okay, I’ve had lots of students who weren’t getting it. When it gets down to it, I’m a mediocre teacher at best who survived the classroom on charisma. But I have vivid memories of this kind of conversation going on in my head all the time.
Often what was frustrating to me was that the concept they didn’t get was not especially difficult (translation: I’ve spent my entire life studying this damn topic so I don’t care if you think it’s boring - suck it up buttercup and read the 200 pages of Kierkegaard I assigned and come back with PhD level notes). I had explained the concept multiple ways (translation: I’ve laid out a detailed technical argument my colleagues in the field have praised me for so why can’t your feeble mind seem to keep up with me, clearly that’s your fault). Other students were following along (translation: one brilliant student understood who didn’t actually need me to be there in the first place). But for this particular student (translation: literally everyone except the one student who doesn’t need me to teach them anything probably), something was not connecting — the ideas were landing as information (translation: they knew who to use copy/paste in a word doc on the vocabulary guide I gave them) but not as understanding.
They were present without being alive (translation: I’m too scared to admit out loud that my teaching may be what is killing them).
That pretty well sums up my first three or four years of teaching in lots of ways. It’s a bit hyperbolic...but less hyperbolic than I care to admit.
Around year four or five (notably at about the same time where my administrative load turned my teaching load into something more manageable, which is an essay for a different time) I watched something happen. I had a pretty motivated student that started coming to class about 15 minutes early and rewriting their notes. They were not the best student, but they were terrified failing and being ineligible during the season. I’m using the word “rewrite” intentionally here. They were not reorganizing them or rereading them. They were rewriting them entirely, trying to do something I tossed off as a line in class on the first day: “try translating every concept you hear in this class into something you feel like you know a lot more about than me.” He was translating every concept into basketball analogies. This student knew basketball the way some people know a language they grew up speaking. They knew it in their bones in ways that are still remarkable to me. And once they found a way to say the thing I was teaching in the language they already knew that deeply, something shifted. The concept stopped being information and started being theirs. (I’m happy to report that student worked hard and got a B+).
What that student did was become the teacher of their own understanding. They did not wait for me to find the right explanation. They built a bridge from territory they knew deeply to territory they were trying to enter — and in the building of the bridge, they crossed it. And, 10 years later I can still enjoy an NBA game in ways I never could before.
This is what the Bridge Bot occasions. Let’s be very, very clear from the beginning: this is not the bridge itself. You cannot hand someone a translation that will work for them in this context. Instead, it’s an honest effort to replicate what I learned from which that student before each class figure out how to build their own bridge in an AI wrapper.
What the Bot Is Actually Doing
The bot’s first move is to find out what the student knows deeply. Not what they know well in an academic sense, but what they know the way the basketball student knew basketball — with fluency, with love, with the kind of embodied familiarity that comes from long engagement rather than study. That domain of deep knowing is the raw material for the bridge. The bot uses it to construct an initial analogy, and this analogy becomes a way of saying the unfamiliar thing in the language of the familiar one. But the analogy is not the destination. It is the starting point for a test.
The philosopher of science Imre Lakatos distinguished between research programs that are growing and research programs that are declining. A growing program organizes more and more ideas around its core thesis in novel and constructive ways; it keeps generating new predictions, new questions, new territory to explore. A declining program spends its energy defending the core thesis against attack. The declining program is always qualifying, always making exceptions, always protecting rather than extending.
A good analogy works like a growing research program. It does not just explain the concept once. It organizes more of the territory around a central insight, producing new “oh, and that also means...” moments as it is extended. A weak analogy works like a declining program: it requires constant qualification and defense, always running into exceptions that have to be explained away.
The bot tests whether the bridge the student is building is growing or declining. If it is growing, the bot extends it further, pushing into new territory the analogy can illuminate. If it is declining, the bot names where and why it breaks down, and then asks the most important question: what does the breakdown reveal about the concept itself? This in turn opens the possibility of establishing a new analogy that might function more like a growing research program.
That question, what does the breakdown reveal, is where the real learning lives. The place where the analogy fails is often the place where the concept is most interesting.
What a Round Actually Looks Like
Theory is cheap here, so here is the bot at work. A student has been asked to make sense of negative feedback loops, and the only thing they know cold is basketball.
Student: A negative feedback loop is like a good team defense. When the other team starts scoring inside, the defense collapses into the paint to shut it down. Then the other team starts hitting outside shots, so the defense spreads back out to cover the perimeter. It keeps adjusting to whatever the offense does, always pulling back toward balance.
Bridge Builder: Good, and notice you’ve already built something structural, not just a resemblance. The size of the defensive adjustment tracks the size of the problem: a couple of points inside, a small collapse; a whole run of them, a bigger one. That proportional response is the load-bearing part. Let me walk one step further out onto the bridge. Your defense has a coach on the sideline reading the game and calling the adjustment. What does the coach correspond to in a feedback loop that has no game and no sideline, say, in a body holding its temperature at 98.6?
Student: The brain, I guess? Something has to notice the temperature is off and decide to fix it. The hypothalamus, or whatever it’s called.
Bridge Builder: Stay right there on the word “decide.” In your defense, the coach sees the deviation and chooses the response. It’s a decision, made by someone who could have chosen otherwise. Is that what’s happening when you start to overheat and your skin begins to sweat before you’ve noticed a thing? Is anything deciding?
Student: ...no. It’s not deciding. The heat just triggers it. It’s chemical. There’s no one reading a scoreboard and calling a timeout. It just happens because of how the system is wired together.
Bridge Builder: So this is exactly where your bridge stops carrying you, and the edge is worth standing on rather than stepping back from. Your defense regulates itself because a mind is watching and correcting. The body regulates itself with no mind watching at all. What does the concept have to contain, then, that a basketball court never needs?
Student: Regulation without anyone doing the regulating. The loop has to control itself with no controller. That’s the strange part, isn’t it. The thermostat doesn’t want the room to be warm. It doesn’t want anything, and it works anyway.
The student walked in with a defensive scheme and walked out holding the strangest and truest thing about feedback, control with nobody in control, and the bot never explained a single thing. It only kept asking what the next piece of the court corresponded to, until one piece had no counterpart, and the missing counterpart turned out to be the whole idea.
How to Use It
Bring the bot a concept you are wrestling with and a domain you have lived inside — a sport, an instrument, a trade, a game, a job you have actually worked. It finds the domain first, builds the opening span with you, and then does the thing almost all advice about analogies skips: it tests the bridge by walking you out onto it, one step at a time, until the bridge either carries you somewhere you couldn’t get to before or sets you down at the exact edge where the concept stops resembling anything familiar and starts being only itself.
For teachers, bring a concept you are about to teach and a domain you know deeply yourself, and watch for where your own bridges break. Those breaks are the places your students will get stuck, and it is better to meet them at your desk than thirty faces at a time.
