The science behind Rumo.

Three decades of neuroscience show that handwriting builds the brain’s reading circuit. Rumo is built on that science.

The Rumo difference

Most reading instruction starts at sound. Rumo starts at meaning.

The Science of Reading starts at sound: letter, sound, blend, word. Rumo starts at meaning: idea, sentence, story.

Phonics-first instruction is built around mapping graphemes to phonemes. It works for many kids. But it leaves out the kids who can’t anchor on sound, deaf and hard-of-hearing learners especially, and it stops short of the part that actually grows comprehension: producing language.

Writing turns reading into something kids do, not something done to them. When a 1st grader writes a sentence about what they read, every word is a tiny act of comprehension. That’s the part phonics leaves on the table, and it’s the part Rumo is built around.

The outcome

The country that asks 1st graders to write the most also reads the best.

On the OECD Survey of Adult Skills (PIAAC), the same reading test given to adults in both countries, the share of Americans who can’t reliably read a job posting or a medication label is now nearly three times the rate in Japan.

Japan · PIAAC 202390%of adults read at a functional level or above, the highest share in the world. Japan’s average score (289) ranks 2nd among all OECD countries.
United States · PIAAC 202372%of US adults read at a functional level or above, down from 81% in 2017. The average score dropped 12 points in six years.

Nearly 1 in 3 American adults now struggles with everyday reading, compared to 1 in 10 in Japan. And the US gap is widening.

Why the gap exists

Japan writes 18× more in 1st grade.

In 1st grade, Japan spends roughly 18× more time writing than the US.

Cutler & Graham (2008), Journal of Educational Psychology, and Graham, Capizzi, Harris, Hebert & Morphy (2014), Reading and Writing, surveys of US elementary teachers reporting writing instruction in the range of 15–25 minutes/day, with dedicated handwriting instruction substantially lower.

Rumo brings that lost daily writing time back: 5 to 15 minutes a day, every day, on what kids actually read.
