Methodology

How a pack stays coherent and on-level.

LingoChorus isn’t a single prompt. It’s a set of deliberate checks that keep a lesson at the right level, keep its parts teaching the same thing, and turn what a class missed into next week’s revision. Here’s what those checks are.

Age matching

Bands run 3–4, 5–6, 7–8 and 9–11 — finer at the young end, where children develop fastest, and capped at primary. The band shapes tone, sentence length, activity type and how much reading or writing is even possible.

CEFR matching

Every generation carries the CEFR level, with per-level guard-rails on which vocabulary frequency and grammar structures are fair game. The definition, the example sentence, the song lyric and the worksheet are all held to the same level, so “A1” means A1 everywhere in the pack rather than drifting with the topic.

Pre-literacy handling

A pre-literate class (about ages 3–4) cannot read or write yet, so those packs come out oral, physical and picture-based: point, chant, trace, colour. Ages 5–6 get single-word recognition and tracing; 7 and up get real reading and writing. This runs through the plan, worksheet and quiz — the youngest classes never receive a reading passage.

Grammar and vocabulary consistency

A lesson teaches one target structure and one vocabulary set. The plan introduces them, the practice stage drills the structure aloud, and everything downstream reuses the same words and pattern rather than introducing new ones.

Song coherence — validated, not assumed

The song is checked against the lesson: every vocabulary word must appear in the lyrics, and the fixed words of the target grammar pattern must recur. If the first draft misses either, the song is regenerated. Coherence between the song, flashcards and vocabulary is enforced, not hoped for.

Four-skills alignment

The listening, speaking, reading and writing activities are built from the finished pack, so they practise the exact same structure and words — no new vocabulary sneaks in. Each carries real student-facing material and an answer key, pitched to the age band.

Quiz alignment

Each quiz item is tagged with what it tests — a vocabulary word or the grammar pattern. Items whose stated answer isn’t among their options are discarded, so a broken question can’t mark a class wrong on something they actually knew.

Re-teaching logic

After class you record how the group did per item — got it, mixed, missed — at the class level, not per student. The next pack you compose recycles what recent classes struggled with, woven into the new topic. “Mixed” counts as a gap, and recycling is capped so one hard week can’t crowd out the new lesson.

Teacher editing and review

Everything is generated as a draft for a teacher to review. Every field is editable, content is labelled AI-assisted, and generated translations should be checked. The methodology assumes a teacher in the loop — the tool proposes, the teacher decides.
