What Great Teachers Do Differently

Two high school science teachers, Mr. Harris and Ms. Albright, have classrooms right next to each other. Their rooms are identical, they teach the same curriculum, and they have access to the same resources. Yet, walking down the hall on any given Tuesday, you can feel a difference. In Mr. Harris’s room, the air is thick with tension. Students are slumped in their chairs, eyes glazed over, a low hum of chatter always threatening to boil over into disruption. He spends most of his energy on classroom management, pleading for quiet, and threatening detentions. Just next door, in Ms. Albright’s room, the atmosphere is electric. Students are leaning forward, debating ideas, scribbling notes, and asking questions that push the boundaries of the lesson. The energy is focused, collaborative, and joyful. There’s no secret magic, no flashy technology, and no difference in the students walking through the door.

So what is it? What’s the variable that transforms one room into a holding pen and the other into a launchpad? The difference lies in how the material is taught. It is about the teacher. This exact puzzle—the subtle, almost invisible distinctions that create wildly different outcomes—captivated Todd Whitaker for years. As a former teacher and principal who went on to become a leading educational researcher and professor, he spent his career observing thousands of classrooms. He wasn't looking for grand, revolutionary teaching methods. Instead, he was fascinated by the small, consistent behaviors—the specific ways a teacher greets students at the door, phrases a question, or handles a minor disruption. Whitaker wrote this book to distill those thousands of hours of observation into a clear set of practices, revealing that the difference between a good teacher and a great one is a matter of deliberate, repeatable choices.

Module 1: The Foundation — Expectations and Intentionality

Great leaders, like great teachers, operate from a foundation of clear expectations. They don't just react to problems. They proactively build an environment where problems are less likely to occur. This starts with a critical shift in focus.

The first principle is that great leaders focus on expectations, not rules. Rules are about what not to do. They are reactive and focus on undesirable behavior. For example, a rule might be "No interrupting in meetings." An expectation, however, is about what to do. It’s proactive and guides people toward desirable behavior. The expectation might be, "We listen respectfully and wait for our turn to speak." Whitaker shows that the most effective teachers prioritize expectations. Good teachers focus on rules. The least effective teachers focus only on consequences. So what does this mean in a professional setting? It means defining the positive culture you want, not just listing the negative behaviors you want to avoid.

From this foundation, we see that every decision must be intentional. Great teachers don't let things happen by chance. They are purposeful in everything they do. If a lesson goes poorly, they don't blame the students. They ask, "What could I have done differently?" This is about taking ownership. It’s about seeing yourself as the primary variable for success. When a project misses its deadline, the great leader reflects on their own planning, communication, and support. Was the goal clear? Were the resources adequate? This intentionality prevents a culture of blame. It builds a culture of responsibility.

And here's the thing. This intentionality extends to every interaction. Whitaker suggests a powerful filter for decision-making. Before you act, ask yourself: "What will the best people think?" Your "best people" are your most responsible, positive, and high-performing team members. If you're considering a new policy, how will it land with them? Will it empower them or burden them? If you base your decisions on your best people, you elevate the standard for everyone. You stop managing to the lowest common denominator. Instead, you create a culture that your top performers want to be a part of. This simple question acts as a powerful guide. It ensures your actions align with the values you want to promote.

Module 2: The Human Element — Empathy and Comfort

We've established the importance of expectations. Now, let's move to the second pillar: the human element. Greatness is about people. It's about understanding and managing the emotional landscape of your team.

A core insight from Whitaker is that great leaders constantly assess who is most and least comfortable. In any situation, some people feel at ease, while others feel anxious or excluded. A great teacher is acutely aware of this. They don't make an example of a struggling student, because that would make the other students uncomfortable. They don't punish the whole class for the actions of a few, because that punishes the students who did everything right. Think about your last team meeting. Who was most comfortable speaking up? Who was least comfortable? Your decisions should aim to make your best people—the ones who are diligent and responsible—feel comfortable and supported. Conversely, when you need to correct behavior, your approach should make the person with the undesirable behavior slightly uncomfortable. This encourages change without creating a toxic environment for everyone else.

Building on that idea, you must treat everyone as if they are good. This means separating the person from the behavior. When you must address an issue, you do it with respect. You assume good intent, even if the outcome was poor. For example, instead of approaching a team member with, "Why did you mess this up?" you might say, "I know we all want this project to succeed. Let's walk through what happened here and see how we can get it right next time." This approach preserves dignity. It keeps the person on your side. It makes them a partner in the solution, not an adversary in a conflict. This is especially crucial when dealing with difficult conversations, like with an upset client or a defensive team member.

So here's what that means in practice. You have to practice empathy by seeing the world through their eyes. Great teachers understand that every student has a unique background. They have different needs, fears, and motivations. The same is true for your team. A junior engineer fresh out of college has a different perspective than a senior director with a family. A great leader works to understand these perspectives. Whitaker suggests a simple method. Put yourself in the role of a learner. Try to master a new skill. The humility and struggle of being a novice will reconnect you with the experience of your team members who are learning and growing. This empathy is a strategic tool that allows you to lead more effectively.
