Why We Teach Reading This Way: Understanding Literacy Basics Through the Science of Reading

Written by Dr. Essie Sutton | Oct 28, 2025 9:05:59 PM

Learning to read is one of the most important milestones in a child’s educational journey. Yet for many students, this process doesn’t come easily—and when early reading instruction falls short, it can affect learning for years to come.

The Science of Reading (SoR) provides a clear, research-based understanding of how the brain learns to read and what instructional approaches consistently lead to success. But understanding the science is only half the battle. Putting it into practice requires the right tools, data, and interventions that ensure every student receives the support they need to become a confident, capable reader.

What Is the Science of Reading?

Dr. Louisa Moats, a leading researcher and co-developer of LETRS professional learning, defines the Science of Reading as:

In other words, the Science of Reading is not a single program or philosophy—it’s a deep, interdisciplinary body of evidence that tells us what works, what doesn’t, and why.

The Five Pillars of Reading

Decades of research have identified five essential components that build the foundation for reading proficiency:

  1. Phonemic Awareness: Recognizing and manipulating the individual sounds (phonemes) in spoken words—understanding that words are made up of smaller sound units.
  2. Phonics: Connecting those sounds (phonemes) with the letters and letter patterns (graphemes) that represent them in written language.
  3. Fluency: Reading text smoothly, accurately, and with expression. Fluent readers can focus less on decoding and more on meaning.
  4. Vocabulary: Developing a rich understanding of words and their meanings, essential for both comprehension and communication.
  5. Reading Comprehension: The ultimate goal—being able to understand, interpret, and reflect on what is read.

When instruction explicitly and systematically addresses these five areas, students build the strong neural pathways necessary for lifelong literacy.

From Research to Practice: Bridging the Gap

Even educators familiar with the Science of Reading often face a key challenge: translating theory into effective classroom practice.

  • What does explicit, systematic instruction look like day-to-day?
  • How do we identify which students need which supports—and when?
  • How do we ensure interventions are working?

This is where data, collaboration, and evidence-based resources become essential.

Using Data to Drive Literacy Support

Effective reading instruction doesn’t stop at whole-group lessons—it thrives when educators can pinpoint where a student is struggling and respond quickly. To do that, schools need timely, actionable data on foundational reading skills.

Within a Multi-Tiered System of Supports (MTSS), this means:

  • Screening all students to identify who may need additional support.
  • Progress monitoring to track whether interventions are effective.
  • Team-based decision-making using consistent data across classrooms and grades.

Without a clear system for collecting and interpreting data, even strong instructional practices can fall short.

Finding Evidence-Based Interventions That Work

Thousands of reading programs exist, but not all are grounded in the Science of Reading. Educators can rely on trusted sources to guide selection, such as:

When schools pair these resources with a data-driven platform like Branching Minds, teams can easily match the right interventions to the right students, monitor fidelity, and measure impact—all within one centralized system.

Putting It All Together: The MTSS Connection

The Science of Reading and MTSS share a common purpose: ensuring that every student gets the instruction and support they need to succeed.
By combining systematic, explicit instruction with structured support systems, schools can move from reacting to reading struggles to preventing them.

This means:

  • Using screening and diagnostic data to inform instruction.
  • Implementing targeted interventions for Tier 2 and Tier 3 students.
  • Monitoring progress regularly to ensure growth.

When these practices are in place, literacy instruction becomes more accessible, consistent, and effective across classrooms.

Next Steps for School Leaders and Teams

For principals, MTSS coordinators, and teachers looking to strengthen literacy practices:

  • Review your current curriculum and interventions. Do they align with SoR principles and cover all five pillars of reading?
  • Ensure instruction is systematic and explicit. Students benefit most from clear, intentional teaching sequences that build on prior skills.
  • Leverage your MTSS platform. Tools like Branching Minds make it easier to see which interventions are working and where additional support is needed.
  • Invest in professional learning. High-quality PD—such as LETRS or webinars focused on foundational reading skills—empowers teachers to bring research to life in their classrooms.

How MTSS and the Science of Reading Work Together

Teaching reading effectively isn’t about following a trend—it’s about following the science. When educators combine evidence-based instruction, collaborative problem-solving, and the right tools, every student has the opportunity to become a confident, lifelong reader.
