From Novice to Expert: Supporting Teachers Through Cognitive Load Theory

When it comes to helping teachers grow from novices to experts, decades of research in education and cognitive science point to one powerful idea: Novices need more structure and scaffolding, while experts benefit from more independence.

This principle sits at the heart of Cognitive Load Theory (CLT), one of the most influential frameworks for understanding how people learn. Developed by Professor John Sweller, CLT helps explain why different teaching approaches work best at different stages of expertise.

Cognitive Load Theory in Education: Why Structure Matters

Two well-established principles from CLT - the worked example effect and the expertise-reversal effect - show how structure should evolve as learners develop.

• The worked example effect demonstrates that beginners learn most effectively when given clear, complete models of how to perform a task. Instead of being asked to “figure it out,” novices progress faster when they can study and replicate an example of success.

• The expertise-reversal effect reveals that as learners gain experience, too much guidance can actually slow them down. Once someone understands the process deeply, they learn more efficiently through practice and problem-solving rather than by observing examples.

In short, what helps a beginner can hinder an expert. Effective teaching means matching the level of instructional support to the learner’s stage of development.

The Novice Teacher’s Challenge

Now imagine a novice teacher preparing a literacy lesson for Monday morning. They know what to teach - perhaps how to decode multisyllabic words or introduce a new spelling pattern - but not necessarily the best sequence of words, visuals, and examples to guide their students.

For a new teacher, creating these materials from scratch can be daunting. Every decision, what to say, what to show, and how to check for understanding, adds to their cognitive load. And when a teacher’s working memory is overloaded, their ability to deliver clear, confident instruction suffers.

What they need, according to Cognitive Load Theory, is a worked example of effective instruction; a model lesson that shows exactly what to say and do to achieve success.

How Readable English Reduces Cognitive Load for Teachers

At Readable English, we've been we’ve been intentional in incorporating the principles of Cognitive Load Theory into every aspect of our program. Our structured literacy program is designed not only for students but for the teachers who guide them. Every Readable English lesson includes:

• Pre-made lesson materials, including visuals, activities, and student resources

• Scripted prompts and teaching guides, providing clear models of effective instruction

• Built-in scaffolds that align with how the human brain processes new information

By embedding these supports directly into the program, Readable English reduces teacher workload and minimizes unnecessary cognitive load, allowing educators to focus on delivery, engagement, and student support rather than (more) preparation.

Over time, as teachers become more confident with the program, they naturally move toward greater autonomy, experiencing the expertise-reversal effect firsthand as they adapt lessons to their own style and students’ needs.

Endorsed by the Founder of Cognitive Load Theory

Professor John Sweller, the founder of Cognitive Load Theory, has formally and publicly endorsed Readable English for its strong alignment with CLT principles.

"Those familiar with Cognitive Load Theory with its emphasis on reducing working memory load during learning will immediately see the benefits of the system... Based on theory and data, I can recommend Readable English in the strongest possible terms. It has the potential to transform the teaching of English." - Professor John Sweller

From Novice to Expert, Supported Every Step of the Way

Becoming an expert teacher takes time, experience, and the right tools. With Readable English, teachers begin that journey with confidence, supported by ready-to-use lesson plans, evidence-based methods, and a program grounded in Cognitive Load Theory.

Readable English doesn’t just help students become skilled readers. It also helps teachers grow from novice to expert, one structured, well-designed lesson at a time.
