Why Teacher Decision-Making Is Essential, Not Optional

Over the past few years, conversations about improving teaching have increasingly focused on one idea: helping teachers make better decisions in the classroom. When this topic comes up in professional discussions, the response is often something along the lines of, “That sounds like something our strongest teachers would really benefit from.”

That reaction is understandable—but it misses something important. Developing decision-making isn’t just valuable for the best teachers. It’s something every teacher needs in order to work effectively.

To understand why, it’s helpful to look at how teaching has evolved over the past decade and a half.

The Rise of Research-Informed Teaching

Teachers today have more access than ever to research about learning and instruction. Studies in cognitive science, psychology, and education have produced valuable insights about how students remember information, how misconceptions form, and which instructional practices tend to support learning.

However, academic research isn’t always written with classroom teachers in mind. Research papers often assume a scholarly audience and are filled with technical language, statistical analysis, and theoretical debate. For teachers who are already juggling lesson planning, marking, and pastoral responsibilities, navigating that research can be difficult.

As a result, a translation layer has emerged. Books, blogs, podcasts, and professional development platforms interpret academic findings and present them in more practical terms. This growing body of “education literature” has played a hugely positive role in making research accessible to teachers.

But there’s another reality that shapes how teachers engage with this information: time pressure.

Teaching is an extremely demanding profession. With limited time to study research in depth, it’s natural for teachers and leaders to look for clear guidance—practical strategies that can be implemented quickly and consistently.

At the same time, inspection systems and accountability pressures often reward schools that appear to have fully implemented particular approaches. Because inspections provide only a brief snapshot of school practice, there is often a strong incentive to demonstrate visible consistency in classrooms.

Together, these factors create a powerful cultural expectation:

• Find the right strategy.

• Implement it quickly.

• Ensure it is visible during observation.

• 
  

When Teaching Becomes Procedural

In many schools, this environment leads to the creation of highly structured lesson formats and lists of techniques that leaders expect to see during lessons.

Teachers might be encouraged, or required, to include specific elements such as:

• a “Do Now” starter task

• live modelling using a visualiser

• cold-calling during questioning

• mini whiteboards for checking understanding

• timed independent practice

• an exit ticket at the end

  
  

None of these techniques are inherently problematic. In fact, many of them are supported by research and can be extremely effective when used well.

The issue arises when the presence of the technique becomes the measure of success, rather than the impact it has on student learning.

A lesson may appear successful simply because the expected steps were followed:

The starter activity was completed. Modelling took place. Students used mini whiteboards. Independent practice occurred. An exit ticket was collected.

But the real question should be: Did those actions help students understand, think, and remember the content?

When teaching becomes reduced to a set of procedures, we risk focusing more on compliance than on learning.

Teaching Is a Complex System

One reason procedural approaches struggle in classrooms is that teaching takes place within a complex environment.

Research on complex systems highlights several characteristics that distinguish them from simple or routine systems.

1. High levels of activity

Complex systems involve many different elements operating at the same time. In a classroom, these elements include students’ prior knowledge, motivation, behaviour, emotions, peer interactions, and the teacher’s instructional choices.

2. Interconnected interactions

In routine systems, elements tend to interact in predictable pairs: A affects B, C affects D. In complex systems, everything interacts with everything else. A student’s question might influence another student’s thinking, which affects the teacher’s next explanation, which changes the direction of the lesson.

3. Unpredictable outcomes

When two elements combine in a routine system, the result is usually predictable. In complex systems, the same inputs can produce very different outcomes depending on context.

Classrooms clearly exhibit all three of these features. They are busy, interconnected, and unpredictable.

Because of this complexity, attempts to impose rigid procedures often fail to capture what is actually happening. In some cases, strict procedures can even be counterproductive if teachers feel compelled to follow them regardless of whether they fit the moment.

What Experts Do in Complex Environments

If teaching is inherently complex, it’s worth asking how experts succeed in other complex fields.

Research across domains such as aviation, emergency medicine, and the military suggests that expert practitioners rely heavily on high-quality decision-making. Rather than following rigid rules, they constantly interpret the environment and choose actions that best serve their immediate goals.

Interestingly, these decisions are often intuitive. Experienced professionals notice subtle cues in their environment and respond quickly based on patterns they have learned over time.

Because this expertise develops gradually through experience, it can be difficult for experts to explain exactly how they make their decisions. Much of their thinking becomes tacit or automatic.

The Role of Purpose in Classroom Decisions

Recent work examining highly effective teachers has revealed a similar pattern.

Rather than organising their decisions around the stage of the lesson or a specific technique they are expected to use, strong teachers tend to think about the purpose they are trying to achieve in the moment.

In other words, they ask themselves: What do my students need right now?

From studying expert classroom practice, several recurring purposes emerge. While the wording may vary, most teaching decisions seem to support one of the following aims:

• gaining or sustaining students’ attention

• helping students understand new ideas

• encouraging deeper thinking

• providing opportunities for practice and consolidation

• strengthening memory

• checking whether students have understood

Nearly every instructional decision can be linked to one of these purposes.

Importantly, there are many different techniques that can serve the same purpose.

Experienced teachers often adapt their methods flexibly depending on the situation.

For example, consider a simple paired discussion activity. Some teachers carefully structure this with clear prompts, time limits, and sentence starters. Others might simply say, “Turn to your partner and discuss.”

If students engage in thoughtful conversation, listen to each other, and build on one another’s ideas, the instructional purpose has been achieved, even if the technique looked informal to an observer.

The Role of Structures and Techniques

This does not mean lesson structures and instructional techniques are unnecessary.

For many teachers, particularly those who are early in their careers, teaching outside their specialism, or simply having a challenging day, clear structures can provide valuable support. They reduce cognitive load and create space for teachers to focus on student responses.

In this sense, techniques and structures function as scaffolds.

The key distinction is that scaffolds should support decision-making, not replace it. Teachers should be able to choose when and how to use particular strategies depending on the purpose they are trying to achieve.

Shifting the Focus to Decision-Making

One practical way to encourage this shift is through how we talk about teaching.

For example, imagine a lesson observation where a teacher used mini whiteboards to check students’ understanding.

A typical comment might be:

“It was great to see you using mini whiteboards.”

While positive, this feedback focuses on the action rather than the decision behind it.

A more powerful approach might involve questions such as:

• What were you hoping to achieve by using mini whiteboards at that point?

• How did that technique help you understand what students were thinking?

• In what situations might you use them differently?

• When might another approach work better?

  
  

Questions like these place the teacher’s thinking at the centre of the conversation. They acknowledge that effective teaching depends on thoughtful decisions rather than simply following prescribed steps.

Building a Culture of Professional Judgement

Ultimately, improving teaching is not just about identifying effective strategies. It is about developing teachers who can choose and adapt those strategies wisely.

When schools prioritise teacher decision-making, they recognise that classrooms are dynamic environments where professional judgement matters.

Techniques and structures still have an important role, but they become tools rather than rules. Teachers use them flexibly in pursuit of clear instructional purposes.

In a profession as complex as teaching, that ability to make thoughtful, responsive decisions is not a luxury reserved for a few experts.

It is a capability that every teacher needs to develop.
