Language homework that actually gets done

Somewhere between a third and a half of adult language students arrive at a lesson without having done the homework. Teachers tend to read this as motivation. It is almost never motivation — these are people paying their own money for optional lessons, which is about as motivated as a student gets.

It is task design. Most language homework is quietly impossible to finish.

The finish line problem

Consider the four most commonly set tasks:

• Review the vocabulary from today
• Practise the past tense
• Read the article and look up new words
• Listen to some podcasts in Spanish

Not one of them has a finish line. There is no state of the world in which a student can say “done”. Review the vocabulary — until when? Until you know it? You cannot verify that alone. Practise the past tense — for how long? Until it is right? It is never quite right.

A task with no completion state has a predictable failure mode: it is deferred, because it can always be done more, so it can never be done now. Then it is deferred again. Then the lesson arrives.

Compare:

• Record yourself saying these five sentences and send them to me.
• Write three sentences about your weekend using sein as the auxiliary.
• Do the first 20 cards in the deck.

Each of these ends. You can look at the task and know whether it is finished. That single property — bounded, verifiable completion — moves homework rates more than any amount of encouragement.

Six rules

1. Bounded

Give a number or a duration. “Five sentences.” “Twenty cards.” “Two minutes of recording.” Never “some”, “a few”, or “regularly”.

2. Under twenty minutes

Adults with jobs and children do not have an hour. If the task looks like an hour, it does not get started — and an unstarted task produces nothing, whereas a ten-minute task produces ten minutes. Small and completed beats large and abandoned, every time.

Ten to fifteen minutes a day, or one twenty-minute task per week, is the realistic envelope for a self-funding adult learner. Design for that, not for the student you wish you had.

3. Production, not recognition

Recognition tasks — reading, listening, matching, multiple choice — feel productive and change little. The student was already going to understand more than they can say; that is the standard adult-learner asymmetry, and passive homework widens it.

Speaking or writing tasks are harder and they are where the gains are. See understand but cannot speak for why this asymmetry develops and what closes it.

4. Built from the lesson, not from a book

Homework drawn from a workbook is disconnected from the thing the student is trying to do. Homework built from the sentences they reached for and could not complete is already motivated — they wanted to say it forty minutes ago.

This is why lesson notes and homework should be the same document. The sentences you captured during the lesson are the homework.

5. Checked, visibly

Unchecked homework is optional homework, and students work this out within about three weeks. Not because they are lazy — because their week contains more obligations than hours, and the unenforced one is the rational thing to drop.

Checking does not need to be heavy. Opening the recording they sent and commenting on one thing is enough. What matters is that the check visibly happens.

6. Repeated across lessons

One-off tasks teach one-off material. The most valuable homework revisits things from three weeks ago, because that is when they are about to be forgotten — which is the entire principle behind spaced repetition.

Five formats that work

Recorded repetition

“Record these five sentences and send them.”

Two minutes for the student. It trains a motor skill, which nothing else on this list does. It gives you diagnostic audio to open the next lesson with, and it produces a visible before/after record over a term that is genuinely motivating to hear.

This is the single best homework format for pronunciation and it is criminally underused, mostly because it used to be awkward to collect.

The five-sentence write-up

“Write five sentences about X using Y.”

Constrained enough to be finishable, open enough to require real production. Mark it by rewriting each sentence as a native speaker would, next to theirs — two columns, no rules. The comparison teaches more than the explanation.

Twenty cards

“Do the first twenty cards in today’s deck.”

If the student uses Anki or the deck from your lesson tool, this is the lowest-friction task that exists. Bounded by definition, and the software handles scheduling.

The failure mode to watch: decks full of isolated words rather than sentences. Isolated words are learned in isolation and stay there.

Shadowing one minute

“Shadow this clip, one minute, three times.”

Trains rhythm and intonation, which almost nothing else touches. Requires no writing, no equipment, and can be done while walking. Full method in the shadowing technique.

Six minimal pairs

“Listen to these six pairs, write down which one you hear.”

Perception homework, for a student who cannot yet hear a contrast. It is fast, it is scoreable, and it fixes the prerequisite that production drills assume. See minimal pairs training.

What to stop setting

“Watch a film in the target language.” Almost pure entertainment at anything below B2. The input is far above the student’s level, so it is not comprehensible input — it is noise with subtitles, and the subtitles are doing all the work.

Long grammar worksheets. Twenty gap-fills teach the twenty gaps. Three sentences the student invents themselves teach the pattern.

“Learn this list of fifty words.” Nobody learns fifty words. They recognise them for four days. Twelve words in sentences, reviewed on a schedule, beats fifty in a list by an embarrassing margin.

Anything you will not look at. If you are not going to check it, do not set it — you are teaching the student that your instructions are decorative, and that lesson generalises.

The two-minute review that changes everything

Open every lesson by checking the previous homework. Two to four minutes, without exception, without apologising for it.

Lesson opening
──────────────────────────────
0:00  "Send me your recording?" → play one, comment on one thing
1:00  Two sentences from last week's notes, used in a new context
3:00  Anything from the corrections column, re-tested
4:00  Lesson proper

The mechanism is not surveillance, it is washback. Students study what gets checked. If the first four minutes of every lesson come out of the homework, the homework becomes the most valuable four minutes of their week — and completion rates change without a single conversation about discipline.

Making the setting cheap

The reason teachers set vague homework is that specific homework is expensive to produce. Five sentences with translations and audio is a genuinely useful task and it takes fifteen minutes to build by hand, per student, per week.

That is the problem Teachee was built to remove: the sentences you capture during the lesson already have their transcript, translation, phonetic transcription and audio attached, so the homework is finished at the moment the lesson ends. You choose what matters; you do not type it out twice.
