A Teacher’s View: What the Science of Reading Looks Like in K-5 Classrooms

K-5 literacy instruction and the science of reading

As a former classroom teacher turned copywriter, I’ve watched the rise of the Science of Reading from two vantage points: inside the classroom and now in EdTech through research and conversations with fellow educators. Honestly, it was a challenging transition for me to rethink everything I thought I knew about how to teach reading. This is true for many educators, who say the shift hasn’t just changed instructional expectations — it’s reshaped core beliefs and how they show up for their students every day.

Summary

The Science of Reading matters because it brings together decades of evidence showing how students learn to read — and how instruction can support that development more effectively. As laws governing literacy instruction evolve, Science of Reading-aligned teaching is becoming the norm rather than the exception in classrooms across the country.

What follows is a breakdown of Science of Reading in clear, teacher-focused terms that highlights the learnings educators have come to rely on.

What the Science of Reading actually means

The Science of Reading isn’t a trend or a boxed program. It’s a massive body of interdisciplinary research — from linguistics to psychology to neuroscience — explaining how children learn to read.

A few core components consistently emerge:

Large-scale reviews show these clusters — oral language, decoding, phonological awareness, fluency, comprehension — are essential to developing skilled readers.

What K-5 teachers say they’ve learned

After talking with educators, reading the research, and reflecting on my own classroom experience, three important themes come up:

Explicit, systematic instruction is non‑negotiable

Direct, systematic phonics instruction improves early reading outcomes — especially in states that have strengthened foundational skill requirements through new legislation.

Foundational skills matter more than we realized

Phonemic awareness and decoding lay the groundwork for everything else. The research reinforces the importance of these early skills, particularly for multilingual learners.

Language and vocabulary are the heartbeat of comprehension

Oral language, background knowledge, and word learning play major roles in reading development — especially in diverse classrooms.

Why reading comprehension is still important

Even with all the talk around phonics and foundational skills, comprehension remains the ultimate goal — and it deserves just as much attention. Research shows comprehension is one of the core components of skilled reading development, right alongside phonological awareness, decoding, and fluency.

Decoding alone doesn’t guarantee understanding. Students also need rich vocabulary, background knowledge, and opportunities to discuss and think deeply about what they read. Studies emphasize that comprehension grows from a combination of language skills, knowledge-building, and independent practice.

Teachers often see this firsthand: strong decoders can still struggle once texts get more complex. That’s why comprehension needs to be woven intentionally into daily instruction — through discussion routines, content-rich texts, modeling strategic thinking, and giving kids time to engage meaningfully with ideas. It’s the part of literacy where reading becomes joyful, empowering, and truly transformative.

What the Science of Reading looks like in a K-5 classroom

In practice, Science of Reading isn’t flashy — it’s structured, consistent, and deeply intentional. When teachers talk about their Science of Reading-aligned instruction, here’s what they mean.
