If you’ve been following the science of reading movement, you know that systematic phonics instruction works. The research is overwhelming. Kids who learn to decode through phonics outperform those taught through whole-language or cueing methods. The Science of Reading Act is a long-overdue correction.
But here’s what most phonics programs miss: decoding words isn’t the same as understanding them. According to Scarborough’s Reading Rope, reading comprehension requires two separate systems working together — word recognition (which phonics teaches) and language comprehension (which most curricula neglect). A child can sound out every word on a page and still have no idea what the story means.
Phonics teaches kids to parse. It doesn't teach them to think.My son is living proof of both the power and the limits of phonics-first instruction — and what happens when you pair it with something most reading programs never consider: computational thinking.
From Three Words to Reading at Three
My son had three words at eighteen months. Mama, dada, and truck. His pediatrician wasn’t worried. I was.
We had been all-in on phonics. Not the alphabet song — actual phonemic awareness. We taught sounds, not letter names. We played “can you think of a word that starts with ‘aah’?” at dinner. We narrated everything in full sentences. We never used baby talk. I worried we’d messed up.
Suddenly at age two, he started speaking in nine-word sentences. By three, he was reading. We may have gotten lucky with timing, temperament, and probably a dozen factors I still don’t fully understand. But the phonics foundation made it possible.
And then I noticed something. He could decode anything — but decoding wasn’t where the real learning was happening.
What Phonics Actually Teaches (A Developer’s Perspective)
I’ve been a software engineer for well over a decade. When I watched my son decode a new word — sounding it out piece by piece, “c-a-t… cat!” — I recognized the process. He was compiling.
A compiler breaks high-level code into machine-readable instructions. It doesn’t memorize whole programs. It understands atomic units and the rules for combining them. That’s exactly what phonics does with language.
Traditional alphabet learning is like showing someone a finished app and saying “memorize this.” Phonics is like teaching the rules to make it. One creates rote regurgitation. The other creates decoders.
But decoding is still an input skill. It teaches kids to process other people’s ideas. What’s missing is the output skill — the ability to build their own.
The Computational Thinking Bridge
Computational thinking — the set of problem-solving skills underneath programming — shows up in most complex thinking:
Pattern recognition: Noticing that puddles form in the same spots every time it rains. Decomposition: Breaking “get dressed” into shirt, then pants, then socks, then shoes. Abstraction: Understanding that “vehicle” means cars, trucks, buses, and trains. Algorithms: Following a recipe step by step. Knowing that order matters. Debugging: “My tower keeps falling. Why? The big block is on top. What if I move it to the bottom?”
These aren’t programming skills. They’re thinking skills. And toddlers already use most of them naturally — they just don’t have a parent naming them.
When my son learned phonics, he was already doing computational thinking. Sounding out a word is decomposition. Applying the same pattern to a new word is pattern recognition. Figuring out why “the” doesn’t sound like “t-h-e” is debugging. Phonics gave him raw material. Computational thinking gave him what to do with it.
What We Actually Do
Our approach isn’t complicated. It’s just intentional.
Phonics gives him tools to decode the world. We still read together daily, still play sound games, still point out words on signs during walks.
Computational thinking gives him tools to build in it. We sort laundry by color and size (pattern recognition). We talk through recipes step by step (algorithms). When his block tower falls, we don’t just rebuild — we ask why it fell and what to change (debugging).
And often, we sit down together and build a game. He describes what he wants. I type it into an AI tool like Claude or ChatGPT to build it. He plays it, finds bugs or potential enhancements, describes what he wants to change, and we iterate.
He’s three. He has a portfolio of games on our family website. He’s not a prodigy — he’s a kid whose parents decided that thinking about how things work matters as much as reading about them.
Beyond the Science of Reading
The science of reading movement is winning the right fight. Systematic phonics instruction should be the foundation of every early reading program.
But the conversation shouldn’t end with decoding. A child who can sound out every word but can’t decompose a problem, spot a pattern, or debug a failure is only halfway equipped.
Phonics teaches them to read the manual. Computational thinking teaches them to build without one.We do both. You can too — no CS degree required. If you want to see what the building side actually looks like on a screen, here’s the framework we use for screen time. And if you want to try building together, here are five computational thinking games you can make with your kid this weekend.
