From Artifact to Instrument: Upper-Level University Student–GenAI Interactions During Problem Solving in an Advanced Mathematics Course
This qualitative study investigates how upper-level mathematics students develop strategic prompting, critical verification, and adaptive workflows to transform generative AI from a conversational artifact into a reliable mathematical instrument, culminating in a novel framework for understanding student-AI interactions in advanced STEM problem solving.

Imagine you've just been handed a brand-new, super-smart robot assistant. It talks like a human, answers instantly, and sounds incredibly confident. You ask it to solve a tricky math problem, and it fires back a long, fancy explanation. But here's the catch: this robot is a bit like a magician who sometimes pulls a rabbit out of a hat, but other times pulls out a slightly confused squirrel. It's great at sounding smart, but it doesn't always know the math.
This is exactly what a team of researchers at Montana State University and the University of Illinois Chicago watched happen when they gave a group of 21 advanced math students (mostly seniors and grad students) a challenge: use these "Generative AI" tools to solve complex problems in a Numerical Linear Algebra course.
The researchers didn't just watch to see if the AI got the right answer. They wanted to see how the students learned to tame the robot. They found that the students didn't just sit back and let the AI do the work. Instead, they built their own mental "guardrails" to turn the AI from a chatty, unreliable artifact into a serious mathematical instrument.
Here's how they did it, broken down into three main moves:
1. The "Prompt Engineer" Makeover
At first, the students treated the AI like a normal chatbot. They asked simple questions, and the AI gave back answers that were often too vague, too wordy, or just plain wrong. The students quickly realized that you can't just talk to this robot like you talk to a friend; you have to speak its "math language."
They started using Strategic Prompt Engineering. Think of this like giving a very specific set of instructions to a very literal intern.
- Chain Prompting: Instead of asking one big question, they broke it down. "First, do this step. Now, check that step. Now, try a different angle."
- Role-Playing: They told the AI, "Act like a skeptical PhD student explaining this to a professor." Suddenly, the AI stopped being chatty and started being rigorous.
- Demanding Formalism: They forced the AI to cite specific theorems and use strict formatting. If the AI tried to wander off into a vague story, the students snapped it back to the math.
The paper suggests that without these specific, engineered prompts, the AI is just a "conversational artifact"—a cool toy that isn't actually useful for serious math. But with the right prompts, it becomes a "mathematical instrument."
2. The "Trust but Verify" Dance
The second big thing the students learned was Epistemic Vigilance. That's a fancy way of saying: "Don't believe everything you hear, even if it sounds confident."
The students discovered that the AI is a "fallible assistant," not a "math god." They found that the AI could give the right final number but explain it with nonsense, or get the number wrong because it dropped a negative sign.
- The "High-Stakes" Rule: In one funny moment, a group actually asked the AI, "Should I trust you for a high-stakes math exam?" The AI honestly replied, "No, you shouldn't rely on me as your only source of truth. I can make mistakes."
- Cross-Checking: The students didn't just accept the answer. They used their own math skills to double-check the AI's work. If the AI said a matrix was invertible, they checked it themselves. If the AI gave a weirdly complex explanation involving advanced concepts the class hadn't even learned yet, they knew something was off.
The paper argues that these students successfully positioned the AI as a supplementary aid rather than an authority. They treated it like a calculator that sometimes hallucinates, requiring them to stay in the driver's seat.
3. The "Tool Gap" Reality Check
Finally, the students hit a wall that had nothing to do with math and everything to do with money and technology. They noticed a huge Utility Gap between free AI tools and paid ones.
- The Free Tier Struggle: Some free tools couldn't even draw graphs or show math equations properly (they just printed a jumbled mess of numbers). Others had strict limits on how long a conversation could be, cutting off the students in the middle of a complex problem.
- The Paid Advantage: The paid versions (or university-provided ones) could handle longer conversations, render math symbols correctly, and give more detailed explanations.
The paper suggests that this creates a Digital Divide. If you only have access to the free, limited version of the tool, your ability to learn and solve problems is physically restricted by the software's glitches and limits. It's like trying to do advanced carpentry with a hammer that sometimes loses its head.
What This All Means
The researchers, who watched 21 students across six group projects and surveyed 15 of them, suggest that the real lesson here isn't about the AI itself. It's about the students.
These advanced students didn't let the AI do the thinking for them. Instead, they learned to shape the AI. They turned a chaotic, probabilistic chatbot into a disciplined tool by:
- Engineering their questions carefully.
- Vigilantly checking every answer.
- Adapting their workflow to the tool's limitations.
The paper explicitly rules out the idea that these students were just passively consuming answers. In fact, the researchers found that if students just let the AI do the work without these guardrails, they actually learned less. The students in this study were the opposite: they were active directors, not passive passengers.
However, the paper is careful to note that this was a study of advanced students who already knew a lot of math. They suggest that this "taming" strategy might not work for beginners who don't have enough math knowledge to spot when the AI is lying. For those beginners, the AI might just be a trap.
So, the next time you see a robot solving a math problem, remember: the robot isn't the hero. The hero is the human who knows how to ask the right questions, check the work, and keep the robot in its place. The AI is just the tool; the human is the master.
