Teaching in an EMI School: Language Support Inside a Subject Lesson

Quick answer: Language support that works sits inside the subject lesson, not before it as a separate warm-up. Pre-teach four to six words that actually block understanding, build a short word bank on the board as the lesson runs, and give students a sentence frame for the one piece of academic language they will need to produce. Treat vocabulary as part of the science or history lesson, not a detour from it.

What does language support inside a lesson actually look like?

It looks like thirty seconds spent on a word, not ten minutes. A teacher writes "erosion" on the board mid-explanation, gives a one-line definition in plain English, points to a diagram, and moves on. The word stays visible for the rest of the period so students can refer back to it without asking.

This is different from a pre-lesson vocabulary list handed out and forgotten. Words introduced at the point of need, attached to something students can see or do, stick far better than words defined in isolation five minutes before they matter.

Which words are worth pre-teaching, and which sort themselves out?

Pre-teach words that carry the concept itself: without "photosynthesis" or "colonisation," the lesson cannot proceed. Do not pre-teach words students can guess from context, such as connecting words like "however" or "meanwhile." Time spent on words students would infer anyway steals time from the words that genuinely gate understanding.

A useful test: read your lesson plan and underline every word a student would need explained to answer the exit question. That underlined list, usually four to six words, is your actual pre-teaching set.

The English Vocabulary Trainer – Grade 4 is built around exactly this kind of tight, topic-linked word set rather than a long generic list, which makes it easy to lift four or five words straight into a subject lesson.

How much class time can vocabulary take before the subject content suffers?

Two to three minutes total across a forty-minute lesson is a workable ceiling: thirty seconds per pre-taught word, spent at the moment the word appears rather than banked at the start. Beyond that, you are teaching an English lesson with subject content attached, not a subject lesson with language support built in.

Sentence frames cost almost no extra time because they replace open-ended instructions rather than adding to them. Instead of "explain what happened," give students "The cause of _____ was _____, which led to _____." The frame does the language work while the thinking stays on the subject content.

A short, visible word bank works the same way. Four or five words on a strip of the whiteboard, added to as the lesson runs, costs seconds and gives students something concrete to point at instead of guessing. The Grammar & Punctuation Practice pack is a fast source of the sentence-frame patterns that make this kind of scaffold quick to build.

What changes when the subject is maths or science rather than English?

The words get denser, so the same tight pre-teaching principle matters even more. "Numerator" or "condensation" have no everyday synonym a student can guess their way to, unlike a history word like "conflict."

A labelled diagram often does more work than a definition here. Point at the part of the diagram the word describes rather than reading a definition aloud, and let students build meaning from the visual and the word together.

How do you differentiate language support inside a subject lesson?

Approaching: a printed word bank with a small picture or diagram beside each term, kept on the desk throughout the lesson.

On level: the sentence frame with one blank removed, so students supply more of the structure themselves.

Above level: no frame, but a challenge to use two of the target words correctly in their own written answer.

What goes wrong with language support in EMI lessons?

First, the vocabulary list grows too long, so none of the words get the repetition they need to stick. Second, support gets front-loaded into a separate block at the start, disconnected from the moment students need the word, and it is forgotten by the time it matters. Third, the same few students answer every vocabulary check because the class never builds in think time, so the support reaches the students who needed it least.

Frequently asked questions

Is this approach tied to a specific EDB scheme or approved word list?

No. This is general classroom material, not an EDB publication and not vetted by any examination authority. Adapt the word choices to your own scheme of work.

How many words is too many to pre-teach in one lesson?

Past six or seven, retention drops sharply for most classes. Trim to the words that actually block the lesson's core task.

Does this work in a class with a wide range of English levels?

Yes, because the sentence frame and word bank scaffold everyone without singling anyone out, and stronger students simply use the words with more independence.

Should the word bank stay up for the whole unit or just one lesson?

Keep it up and add to it across the unit. A growing, visible bank becomes a genuine reference tool rather than a one-lesson prop.
