Differentiation in Mixed-Ability Language Classes

Differentiation in a language class means offering different routes to the same aim: some learners need more support, some need more challenge, some need more time. It does not mean writing a separate lesson for every learner. In practice, changing one lever at the right moment, such as support or expected output, makes the biggest difference.

Why language classes are especially mixed

Language groups are rarely homogeneous. Learners differ in previous exposure to the language, in other languages they speak, in age, in confidence when speaking and in how fast they read and write. A class with a common level on paper may still range from learners who understand almost everything to learners who struggle with instructions. A short diagnostic at the start of the year, described in placement tests, helps you see this spread before you plan.

The four levers

Lever	What changes	Example for the same task
Support	Amount of help available	Phrase card with sentence starters vs. no card
Task	Complexity of what learners do	Find three facts in a text vs. compare two texts
Output	What learners produce	Five sentences vs. a short text with opinion and reasons
Pace	Time and amount	Core task for all, extension tasks for those who finish

A useful habit is to choose one lever per activity. Using all four at once quickly becomes hard to manage.

Strategies that work with little preparation

Common core, optional extensions

Everyone completes the same core task. Extension cards build on it: an extra question, a more demanding text, a creative follow-up. Learners who finish early continue without waiting, and nobody is visibly given an “easy” version.

Choice of output

After working with the same input, learners choose how they show what they understood: a list of key points, a short summary, a dialogue or a voice message. This also works well with digital tools that support audio.

Phrase cards and sentence starters

A card with six to eight useful phrases for the task is the simplest form of scaffolding. Weaker learners use it from the start, others can turn it over and only look if they get stuck. The same principle is central in CLIL, where language support makes subject content accessible.

Tiered texts

Prepare the same content at two levels of difficulty. Both groups answer the same questions, then mix to compare answers. Here AI tools can save time, as described in AI in language teaching, provided you check the simplified version for accuracy.

Flexible grouping

Change groupings depending on the purpose:

• Same level for targeted practice of a structure.
• Mixed level for tasks where stronger learners explain and weaker learners hear more language.
• Interest-based for projects and reading choices.

Example: one reading task at three levels (B1 class)

Topic: a newspaper article about a town introducing car-free Sundays.

Version	Task	Support
Core	Answer five questions on the main facts	Glossary of eight words
Extension 1	Find two arguments for and two against	Table template
Extension 2	Write a short reply as a local shop owner	No template, model opening sentence only

All learners discuss the topic together at the end. Everyone has something to say, because everyone read the same article.

Using learners’ other languages

In many classes, learners bring several languages with them. These are a resource for differentiation, not a distraction. Learners can note new words with a translation in a language they know well, compare structures (“How do you say this in your language?”) or prepare ideas in their strongest language before speaking in the target language. The CEFR Companion Volume explicitly describes plurilingual competence, so this is not a step back from target-language teaching but a bridge towards it. Keep the final product in the target language and use other languages for thinking, planning and checking.

Differentiating homework

Homework is an easy place to start, because learners work alone anyway. Offer a short menu: one compulsory task for everyone and two or three options with different focus (a reading text, a listening clip, a writing task). Learners choose one option and note why. Over a term this also shows you which skills individual learners prefer to practise and which they avoid.

Assessing in a differentiated class

Differentiation in practice does not mean different standards for marks. Keep the assessment criteria the same and vary the support during learning. In self-assessment, can-do statements help learners see their own progress regardless of their starting point, as explained in self-assessment and language portfolios.

Realistic planning

Start small: one differentiated activity per lesson is enough. Collect phrase cards, extension tasks and tiered texts in a folder so that they become reusable material. The lesson planning guide shows where in a lesson differentiation usually pays off most: in the freer practice phase, where differences between learners show most clearly.
