The Teacher Tips series is written for educators in all settings — classroom instructors, clinical trainers, preceptors, mentors, and anyone in a role where they share knowledge and shape practice. Starting soon, watch for Shift Notes — a new series specifically for educators in clinical supervisory and leadership roles.

When I was a very young instructor in my early twenties, I would sometimes get a type of student who, at the time, stressed me out a lot. This student would often be older than me, and they would ask me hard questions that differed from what I was teaching in the classroom. One of these students was a woman who had previously worked as a phlebotomist, but hadn’t worked in many years after getting married and having a few children. With her kids getting older, she had decided to return to the workforce and was taking the class to get a refresher on phlebotomy knowledge and a shiny new certificate.

I am sure she saw me — a young teacher with only a few years of both phlebotomy and teaching experience — and immediately questioned if she was getting her money’s worth. I don’t blame her at all for thinking that way. She was twice my age and had more phlebotomy experience than me. As I’ve gotten older, I have taken classes where I felt much the same, watching some young new instructor and questioning their knowledge.

The problem was that her previous experience was outdated, and most of it was incorrect. She had a lot of questions, and had a hard time accepting the new information from me, a young educator still trying to find her teaching style. She would ask challenging questions in front of the class — things that differed from what I had just explained. She would argue that certain things were unrealistic, or that this was not how she had seen it in the real world.

She had learned to stick at a 45-degree angle with her straight needles, ripped the fingertip of her glove off before drawing, always marked the vein with a pen (something I didn’t allow), learned an order of draw that started with red tops first, and brought a handful of other habits that all needed to be corrected.

Every day was a new topic that she had questions or disagreements about. I dreaded having to deal with her, and made sure I was as prepared as possible with my information to counter her arguments. She didn’t yell, she wasn’t really rude (but also not very nice), and she pushed. She wanted to know why things were different, why it was better, when it had changed. Most of the things she asked were perfectly reasonable, but some of them became arguments just because she didn’t like the changes.

The imposter syndrome was strong. I felt like she was undermining my authority in front of the whole class every time she asked her questions. I had never had a student challenge me so much. There were other problematic students in that class too (for different reasons), and every day I felt like I was running the gauntlet. It was the first class (but not the last) that made me question if I was cut out to be a teacher.

She taught me so much.

My first instinct was to be defensive and give her answers that essentially said “this is the way it is.” But I knew that wouldn’t work. I hated answers that weren’t real answers, and I had always struggled myself when teachers or parents or whoever said that to me. I want to know more. Don’t dismiss me, tell me why. So, for this particular student and for all my challenging students like this in the future, I explained. I taught. Sometimes I said “I don’t know.” And over time, her questions became less pushy, less challenging towards me. She still asked plenty of them, but she was gentler, a little more respectful.

At the end of the program, she told me she thought I was a good teacher, and that she had learned a lot. She had been nervous to return to school after so many years, and she was the oldest person in the classroom by far. She didn’t know if she could do this anymore, but she had learned that she could. After breaking her bad habits, she had done well, and she had aced every test. She felt confident to re-enter the workforce. She thanked me — and my cortisol levels finally dropped back to normal.

Instructors who teach in phlebotomy programs and courses are hired based on clinical experience. We aren’t formally trained educators who have been taught how to handle a classroom with difficult students and complicated situations. We are often learning how to be a teacher just as much as the students are learning how to be healthcare professionals. They feel like they have to have all the answers and be the absolute authority on the subjects they are teaching — and honestly, so did I.

When a student pushes back on your instruction — especially in front of the class — it’s easy to take it as a personal challenge. But the way you respond will define your classroom far more than the challenge itself.

The experience of that student stayed with me. Not because she was my worst (she was nowhere near the worst), but because she was a real test as an instructor. And if you’ve spent any time teaching in any capacity — whether in a formal program, a hospital orientation, or a one-on-one training session — you’ve probably met a version of her too.

The student who argues.

Not the one who asks thoughtful questions. Not just because they need extra clarification. The one who pushes back. Repeatedly. Sometimes in front of everyone.

Here’s what I’ve learned after years of teaching: how you handle that student says more about your classroom culture than almost anything else you do.

It’s Not About You

The first thing to get right is this — pushback from a student is almost never a personal attack, even when it feels like one.

When a student challenges your instruction, they’re usually not trying to undermine you. They’re drawing on their own experience, something they read, something a previous instructor told them, or simply a confidence in their own knowledge that outpaces their actual skill level. That’s a teaching problem, not a threat to your authority.

The moment you take it personally, you’ve already lost the upper hand — not because the student won, but because you’ve shifted from educator to defender. Nobody learns anything when the instructor is busy protecting their ego.

That’s easier said than done, especially early in your teaching career. When someone challenges what you just taught in front of a room full of students, the instinct to prove yourself is real. Resist it. Take a breath. Then teach.

“That’s a great question, and a pretty common misconception. Here’s why…”

You Don’t Have to Know Everything

Here’s something I wish someone had told me when I first started teaching: you are allowed to not have every answer.

If a student raises a point that genuinely gives you pause — something you’re not sure about, something that’s evolved in the literature, something worth looking into — say so. “That’s a great point. I want to make sure I give you an accurate answer, so let me follow up on that.” Then actually follow up.

What you can’t do is make something up, dismiss the concern entirely, or get flustered. Students respect honesty, and they can sniff out lies like a bloodhound. What erodes your authority isn’t admitting uncertainty — it’s being caught in an error you insisted wasn’t one.

That said, there’s a difference between genuine uncertainty and a student trying to convince you that the wrong way is acceptable. When a student argues against established standards — CLSI guidelines, best practice protocols, institutional policy — that’s not a knowledge gap you need to fill. That’s a redirection moment.

Validate, Then Hold the Line

One of the most effective things I’ve ever done in a classroom is validate a student’s reality before redirecting them to the standard.

I had another student who had worked as a phlebotomist years before returning to formal training. A few times throughout the course, she would periodically announce, in front of the class, that in her previous workplace they allowed a two-minute tourniquet application time — and that the one-minute standard we were following seemed unrealistic. She wasn’t hostile about it. She wasn’t asking a question, either. She was stating it as fact, and other students were listening.

I could have dismissed her. I could have told her that what she did before didn’t matter here. Instead, I acknowledged her.

“You’re right that loose tourniquet time rules are pretty common in the field. A lot of facilities don’t enforce the one-minute limit strictly, and I understand that’s what you experienced. But common practice and best practice aren’t always the same thing. Here’s why the standard exists — and here’s what the evidence says happens when we exceed it.”

Then I covered tourniquet time again. For everyone.

She never argued that particular point again. And the rest of the class got a reinforcement of a critical concept they probably needed to hear twice anyway.

The formula is simple: acknowledge what’s true, clarify what’s standard, explain why it matters. You’re not agreeing with them. You’re not dismissing them. You’re teaching — which is exactly what you’re supposed to be doing.

When It Becomes a Pattern

A student who argues once is giving you a teaching moment. A student who argues every class is giving you a classroom management problem.

If a particular student is repeatedly challenging your instruction, disrupting the flow, or creating a dynamic where other students are unsure who to listen to, it’s time to address it directly — and privately.

Don’t do this in front of the class. Pull the student aside during a break or after class and have a straightforward conversation. Something like:

“I’ve noticed you’ve had some strong reactions to a few of the things we’ve covered. I want you to know that questions and discussion are always welcome — I encourage that. But I also want to make sure the classroom stays productive for everyone. If you have a concern about something I’ve taught, I’d love to hear it. Let’s talk about it here, and if there’s something worth addressing with the group, we’ll do that.”

This does several things. It shows the student you’re not afraid of them. It opens a real dialogue rather than a performance. It makes clear, without making a scene, that the current pattern isn’t working. And it often reveals something useful — sometimes the arguing student is covering for anxiety, a past bad experience, or a genuine misunderstanding that hasn’t been resolved.

Always document these conversations when they happen. If the behavior continues and you eventually need to escalate to a formal concern, you’ll want a record.

Keeping Your Authority Without Losing Your Cool

Authority in the classroom isn’t something you demand. It’s something you demonstrate — through your knowledge, your consistency, your composure, and the way you treat your students even when they make it difficult.

The instructor who snaps at a challenging student, shuts down questions, or visibly bristles at pushback loses the room. Not just with that student — with everyone watching.

A few things that help:

• Stay curious, not combative. When a student challenges you, get interested. Ask them to tell you more about where they learned that. Often the answer itself reveals the disconnect, and you can address it from a place of information rather than reaction.
• Keep your voice even. The tone you set when a student pushes back tells the class everything. Steady and calm communicates confidence. Elevated and defensive communicates insecurity — even if your content is correct.
• Redirect to the standards, not to yourself. When you need to hold a line, hold it against the guideline, not your own preference. “The CLSI standard and your textbook require this” lands differently than “this is how I teach it.” One is an authority the student can look up. The other is a personality conflict waiting to happen.
• Know when to table it. If a debate is going nowhere and eating up class time, it’s okay to say, “I think this is worth a deeper conversation — let’s plan to talk after class and we’ll get back to the group if there’s something worth sharing.” That’s not backing down. That’s running a classroom.

Stay professional, stay patient, stay kind, and when you educate your students with firm rules and correct information, they will listen.

The Student Who Argued — And What She Taught Me

Looking back on the student I described at the beginning of this post, I’m grateful for her. Not because she made my life easy — she didn’t. But because she made me a better instructor.

She forced me to know my material cold, to be prepared for challenge, and to learn the difference between confidence and defensiveness. She taught me that my job isn’t to be right in front of students — it’s to help them understand what’s right, and why.

The argumentative student is a fixture of every teaching career. When you learn to see them not as a threat to your authority but as an invitation to demonstrate it, they stop being your hardest students. They become some of your most useful ones.
