Didactique des langues: Language Teaching Methodology

Didactique des langues — "language didactics" — is the name the French-speaking world gives to the discipline that studies the teaching and learning of languages. It is easy for an English speaker to read the phrase as a slightly formal synonym for "teaching methodology", but that undersells it. In the French tradition, didactique is a field of inquiry in its own right, on a par with the didactics of mathematics or of history, with its own concepts, its own theorists and its own object: not a particular method, but the whole three-way relationship between the learner, the language, and the teacher who mediates between them.

The distinction matters because it changes what counts as the subject. A methodology asks "which techniques work?" Didactics asks a prior question: what actually happens when a body of knowledge — a language — is turned into something that can be taught in a classroom, learned by a student, and tested? That reframing, and the vocabulary built around it, is what sets the francophone tradition apart from the Anglophone one it grew up alongside.

Didactique, methodology, and applied linguistics

Three words that English tends to blur are kept carefully apart in French, and getting them straight is the quickest way into the field.

Pédagogie (pedagogy) is the general art of teaching — classroom management, motivation, assessment, handling a mixed-ability group. It is not tied to any subject: a good pedagogue can run a maths class or a language class, because pedagogy is about the act of teaching, whatever the content.
Méthodologie (methodology) has two senses. In the abstract it means the study of methods; in the concrete, French uses "a methodology" to name a coherent, historically situated teaching system — the direct methodology, the audiovisual methodology, the active methodology. A methodology in this second sense is one of the objects that didactics studies.
Didactique (didactics) is the encompassing discipline. Unlike pedagogy it is tied to a subject — the didactics of languages — because its central problem is specific to the content being taught: how the particular thing that a language is gets transformed for teaching and reconstructed by a learner. Methodologies come and go; didactics is the field that describes, compares and theorises them.

Where does this leave applied linguistics, the term the English-speaking world reaches for instead? The two fields overlap heavily — both are concerned with real language teaching — but they are not the same, and their difference is instructive. Anglophone applied linguistics grew out of linguistics and takes language itself as its principal parent discipline; language teaching is one application among many (alongside translation, assessment, clinical work and language policy). French didactique, by contrast, defines itself as autonomous. It draws not only on linguistics but on the general didactics of school subjects — sharing concepts with the didactics of mathematics and science — and it insists that its object is the teaching-and-learning situation, not language in the abstract. Put simply: applied linguistics starts from language and asks how to use it; didactique starts from the classroom encounter and asks what makes it work.

Key concepts: didactic transposition and the didactic contract

What most clearly marks didactics off as a discipline is a small set of concepts it borrowed from the didactics of mathematics and made its own. Two are worth knowing because they capture something real about any act of learning a language.

Didactic transposition (transposition didactique), introduced by Yves Chevallard in 1980, names the chain of transformations by which scholarly knowledge becomes taught knowledge. A language as described by linguists (the "scholarly knowledge") is not what appears in a coursebook (the "knowledge to be taught"), which is again not what the teacher actually presents (the "taught knowledge"), which is not yet what the learner internalises. At each step something is selected, simplified, reordered, sometimes distorted. Chevallard's point — and Guy Brousseau's gloss on it — is that this transposition is inevitable and necessary but never neutral, and so must be "kept under surveillance". For a language, it explains why the grammar in a textbook is a tidied-up fiction, and why a rule as taught can quietly diverge from the language as spoken.

The didactic contract (contrat didactique), from Brousseau, names the mostly unspoken set of mutual expectations between teacher and learner about who is responsible for what. When a student assumes that every sentence in an exercise must contain the grammar point just presented, or that there is always one right answer the teacher is waiting for, that is the didactic contract at work — invisible until it is broken. In language learning it shapes how much risk a learner will take, whether errors feel like evidence of progress or like failures, and how far the classroom rewards genuine communication versus display of the rule.

These two ideas are exactly what applied linguistics, coming from linguistics rather than general didactics, tends not to foreground — and they are the clearest sign that didactique is a distinct intellectual tradition rather than a French label for the same thing.

Figures and history: from the CREDIF to didactology

The discipline has a fairly precise birth story. Through the 1950s and 1960s French language teaching was dominated by an ambitious research effort centred on the CREDIF (Centre de recherche et d'étude pour la diffusion du français) at the École normale supérieure of Saint-Cloud. Working from a frequency survey that produced the Français fondamental — a core of roughly 1,500 everyday words — and in partnership with Petar Guberina's phonetics team at the University of Zagreb, the CREDIF developed the structuro-global audiovisual (SGAV) method, also called the Saint-Cloud–Zagreb method. Its flagship course, Voix et Images de France (1961), paired recorded dialogues with filmstrip images and became the emblem of French-as-a-foreign-language (FLE) teaching for a generation. This is the direct ancestor of what is covered under audiovisual language teaching.

In the 1970s the terminology shifted. What had been called "language pedagogy" or "methodology" began to be called didactique des langues, marking the claim that foreign-language teaching deserved to be treated as a research discipline, not merely a body of classroom recipes. Three names shaped what followed:

Robert Galisson pushed the claim furthest, arguing for a self-aware discipline he preferred to call didactologie des langues-cultures. Two things in that phrase matter: "-logie", to mark that the field must also study itself and its own history, and "langues-cultures", to insist that a language can never be separated from the culture it carries — language teaching is always culture teaching.
Christian Puren became the discipline's historian of methods. His work — notably the idea of didactics as standing "at the crossroads of methods" and his defence of a principled eclecticism — traced how each methodology (traditional, direct, active, audiovisual, communicative) answered the problems left by the last, and gave later theorists a map of where they stood.
Daniel Coste, also from the CREDIF, bridged French didactics and the European project, becoming one of the architects of the Common European Framework and of the notion of plurilingual competence.

Alongside FLE, the field diversified: French as a second language (FLS) addressed contexts where French has official status but is not the mother tongue, and from the late 1990s plurilingualism — the idea that a speaker's several languages form one interlinked competence rather than separate compartments — became a central theme.

Didactique today: the action-oriented turn

The most influential contemporary idea from this tradition is the action-oriented approach (perspective actionnelle), built into the Common European Framework of Reference (CEFR). Its premise is that a language user is not merely a communicator but a social actor who accomplishes tasks — many of them not purely linguistic — in real situations and social settings. Learners become "co-actors" who cooperate to get something done, and language is the tool that lets them do it.

This is where the francophone and Anglophone traditions visibly rejoin. The action-oriented approach extends the communicative one, and its central unit — the task — is the same notion that English-speaking researchers such as David Nunan, Jane Willis and Rod Ellis had developed as Task-Based Language Teaching. The CEFR effectively synthesised both lineages. Puren, meanwhile, reads the shift as a genuine change of goal: from training a learner to communicate with foreign speakers to preparing them to act together with them — a small phrase with large consequences for how a course is designed.

What this means for learning a language

Didactique is a discipline built by teacher-trainers, so its lessons land directly on how you study — even if you never open a French pedagogy manual. Three of its ideas are worth carrying into your own learning.

First, didactic transposition is a warning about textbooks. The grammar you are handed is a simplified, teachable version of a living language, not the language itself — useful scaffolding, but something to outgrow by exposure to how the language is really used. Second, the didactic contract explains why the right mindset matters: if you treat errors as data about your developing system rather than as failures, and reward yourself for meaning something rather than for reciting a rule, you are rewriting the contract in your own favour. Third, the action-oriented turn tells you what the endpoint is — not to know about the language but to do things with it. That is the same conviction that runs through the whole history of language-teaching methods: a good method, like a good learner, keeps the goal fixed on use.

FAQ

What is didactique des langues in simple terms?

It is the French-language discipline that studies how languages are taught and learned — the equivalent, roughly, of "language education" as a research field. It differs from a teaching methodology in that it does not just recommend techniques; it theorises the whole relationship between learner, language and teacher, using concepts such as didactic transposition and the didactic contract that it shares with the didactics of other school subjects.

What is the difference between didactique and pédagogie?

Pedagogy is the general craft of teaching — motivation, classroom management, assessment — and is the same whatever subject you teach. Didactics is tied to a specific subject, because its core problem is specific to the content: how a language in particular is transformed for teaching and rebuilt by a learner. You can be a fine pedagogue in any classroom; you are a didactician of something.

Is didactique des langues the same as applied linguistics?

They overlap but are not identical. Applied linguistics is an Anglophone tradition rooted in linguistics, for which language teaching is one application among many. Didactique is a francophone tradition that defines itself as an autonomous discipline, draws on the general didactics of school subjects as much as on linguistics, and centres the classroom teaching-and-learning situation rather than language in the abstract.
