Using multilingual knowledge and experience

Use knowledge across languages while checking meanings and preserving opportunities to develop the target language.

Use the examples to connect this lesson with the earlier topics. No specialist equipment is needed.

Back to the chapter

After reading, you can

  • Identify a productive multilingual resource.
  • Check a translation or cross-language connection.
01

More than one route to an idea

A learner first learned fractions through a home language and now encounters them in another language. Asking the learner to ignore the earlier language discards possible knowledge and explanation resources. Inviting a comparison can reveal both what is already understood and where terms organise ideas differently.

02

Use the available repertoire

Learners may draft an explanation in a familiar language, annotate a diagram bilingually, compare terms with a peer or consult a checked multilingual glossary. These are possible routes into the content, not evidence that every multilingual learner needs the same route. Ask which resources are useful and accessible.

Then connect the idea to the language required for the current goal. If the target includes writing a scientific explanation in English, planning in another language can support that work while the learner still practises the final English explanation. The support should not silently replace the target activity.

03

Check meaning rather than surface equivalence

Translations can differ in precision, context and conventional usage. A shared word form does not guarantee a shared technical meaning, and an automated translation can sound natural while altering a condition or negation. Check essential terms using examples, a reliable glossary or a knowledgeable person.

UNESCO’s multilingual education guidance treats languages learners understand as an educational and policy resource. It is guidance for systems and implementation, not a guarantee that any particular bilingual worksheet improves every outcome. Classroom choices still need attention to teacher knowledge, materials, participation and evidence of learning.

Worked example

A bilingual explanation of a proportion

What must the bilingual proportion explanation make unambiguous?

  1. A learner writes a familiar-language explanation of why doubling both quantities preserves a ratio, adds the required terms in English and labels the same quantity pairs on a diagram. A peer asks whether “twice as much” refers to one quantity or both. The learner revises the English sentence to remove ambiguity and solves a new proportion independently. The task uses earlier knowledge while checking both the mathematical relationship and the target communication.
  2. Learners may have uneven knowledge across languages: a concept learned at home can be easy to explain conversationally while its formal school vocabulary remains unfamiliar. That pattern need not indicate confusion about the concept. Compare explanations and applications, then teach the missing terms. Let the learner choose whether a bilingual draft, diagram or another available route is most useful.

Both quantities must be multiplied by the same factor. Use cases to check that “twice as much” has not been translated as changing only one quantity.

Try it yourself

Think through each question before opening the answer.

  1. Why should an automated translation be checked with an example?

    Show the answer and reasoning

    A fluent phrase can alter a technical relationship.

    Applying it to a case can expose a changed condition, comparison or meaning.

  2. Does using a home language prevent learning a new academic language?

    Show the answer and reasoning

    That conclusion does not follow.

    The relevant design question is how the support connects existing understanding with meaningful practice in the target language.

What to carry forward

  • Use multilingual knowledge as a resource.
  • Check technical meanings and make target-language practice explicit when it is a goal.
