The Methodology
One-on-one, online English language arts in the MCT gifted-ELA tradition. Every session runs The Loop — Read → Think → Speak → Write. We build English Thinkers at mastery level.

The LCS System is how DODO Letter House teaches English language arts: Literacy, Composition and Speaking, run in every one-on-one session as The Loop, Read → Think → Speak → Write. It draws on the MCT gifted-ELA tradition and Harvard Project Zero’s Visible Thinking routines, and we measure reading with Lexile and score writing on the skills of each level.
See It Live
Ninety seconds inside an LCS classroom — Read, Think, Speak, Write — in the time it takes to make a cup of coffee. The mechanism on this page, working.
Inside the System
LCS is the shape of a whole language education, not a list of subjects. Literacy is where language goes in. Composition is where it comes back out, in an order that holds. Speaking is the part a book cannot do for you. Five content strands sit under those branches, and more than one of them is running in any given session even when only one has your child’s attention.
Literacy
文学精读
The reading treasury — where language goes in, and the root of everything a child later writes or says.
Composition
系统写作训练
The construction engine — where language comes out, and where thinking has to survive being written down.
Speaking
表达
DODO’s own strand, and the reason there is a Navigator in the room at all. Oral defence, Socratic dialogue, taking the side you disagree with. It has no nested strand because nothing in a curriculum of books supplies it.
Read → Think → Speak → Write is how one session runs. The strands are what the sessions are made of.
Why a Loop
Vocabulary drills produce vocabulary. Grammar exercises produce grammar. Neither produces a student who can read a difficult text, form a position on it, argue that position aloud, and commit it to the page with precision. That requires training the entire loop — not the individual steps in isolation.
Read
Every text in the ELA Program is selected at or just above the student's current Lexile level. Not to frustrate — to stretch. Reading is grounded in the MCT Language Arts tradition: classical literature that climbs with the student — Alice in Wonderland in the early years, Treasure Island mid-way, the SAT canon like The Great Gatsby by high school — paired with Lexile-matched supplements at each student’s current level. Vocabulary depth and reading stamina grow when the text asks something of the reader. We track that growth with Lexile measurement, not guesswork.
Lexile-targeted text selection every session.
Think
The failure mode of most English instruction is this: students learn to produce language before they have learned to produce thought. The Loop forces thinking first. Before a student opens their mouth, they've formed a position — in whatever language their mind works in. The Navigator creates the space for this using Visible Thinking routines drawn from Harvard Project Zero — structured protocols developed at the Harvard Graduate School of Education to build analytical depth.
Structured pre-speech prompts in every session.
Speak
Every session includes a live Socratic exchange with the Navigator — a specialist in literature or composition holding a degree from a world top-50 university (Oxford, U of T, Queen’s, LSE and others), and a native English speaker. The student takes a position and defends it. The Navigator does not correct in real time — they guide. Fluency is not the goal of this phase. Clarity of thinking, expressed in English, is. The difference matters.
Live Navigator-led discussion every session.
Write
Writing develops along the MCT Language Arts progression — Grammar Island → Sentence Island → essay craft → academic composition. Every piece is scored on the skills of the student’s level: building sentences and paragraphs at the first levels, essay structure, style, grammar and usage at the upper ones. The scores are on every progress report.
Writing scored on every progress report, at weeks 4, 8, 12 and 16.
Two Session Types
Type A · Literacy Session
The student reads aloud and engages the text. The Navigator coaches at the sentence level — vocabulary, intonation, comprehension — with precision, not generic encouragement. Anchored on the MCT Building Language / Caesar’s English vocabulary track plus the assigned novel.
Type B · Writing Session
The student thinks, discusses, and drafts. The Navigator opens with a Visible Thinking routine, asks a sharper question before any evaluation, and scores the writing on the skills of the student’s level.
In the common setup, a week holds one Literacy lesson and one Writing lesson. On a plan of one lesson a week, the two take turns.
The Measurement Framework
Lexile levels are used by Canadian provincial school systems, US state curricula, and the Common Core framework to measure and track reading development. When a student's Lexile moves at DODO, it means the same thing it means when it moves at their school. The measurement is transferable. The progress is real.

How Writing Is Scored
Writing is scored on the skills of your child’s level: building sentences and paragraphs at the first levels, essay structure, style, grammar and usage at the upper ones. Each written report also rates reading and language, and oral and listening, and ends with the Navigator’s notes.

English is built out of Latin and Greek — about sixty percent of it, and over ninety percent of the language of science. We teach the roots beneath the words, so a term your child has never seen becomes one they can take apart and solve. It happens to be one of the most-researched strategies in education, which means you do not have to take our word for any of it.
The studies
In a study of 493 middle-school students, root-based vocabulary teaching outperformed traditional vocabulary instruction — for gifted and typically-developing students alike.
Gallagher, S. A. (2017), Roeper Review 39(2)Across dozens of controlled studies, teaching the structure of words produces measurable gains in vocabulary, decoding and spelling.
Goodwin & Ahn (2010, 2013); Bowers, Kirby & Deacon (2010)The gains are larger when word structure is taught together with other literacy work rather than on its own — which is why it lives inside the literature here, not beside it.
Bowers, Kirby & Deacon (2010), Review of Educational Research 80(2)Children grow most on rich, challenging text rather than simplified readers. That is why we read real, unabridged classics, set a step above the comfortable level on purpose.
Shanahan; Keys to Literacy — challenging-text researchRoots are the reason the vocabulary transfers. A child who knows spect reads their way into inspect, circumspect, spectrum and spectacle without being taught a single one of them.

The LCS System is built on three publicly documented, academically validated frameworks: the Michael Clay Thompson (MCT) Language Arts curriculum — one of North America’s most rigorous classical ELA programs, built for students capable of genuine mastery; Harvard Project Zero’s Visible Thinking routines, developed over two decades at the Harvard Graduate School of Education; and Lexile measurement from MetaMetrics. All three are used at scale in education. All three produce measurable, transferable outcomes.
The diagnostic consultation is where we find out exactly where your child is — and show you what The Loop looks like for a student exactly like yours.
