Concept

Language Across the Curriculum (LAC) is the pedagogical principle that language learning is embedded in every subject rather than confined to a language period. In every classroom, language is the medium through which learners listen, speak, read, write, discuss, and construct subject knowledge.

Therefore, responsibility for developing learners’ language proficiency is shared across the teaching staff: each teacher supports the language practices needed to learn that teacher’s subject.

Application

A science teacher explains observations and guides scientific writing; a mathematics teacher develops precise reading of problems and mathematical explanations; and a social-studies teacher supports discussion and evidence-based writing. These are language-learning opportunities within subject teaching, so “All school teachers” expresses the LAC responsibility.

Contrast

• “Parents or guardians” describes participation by parents or guardians in a learner’s education; it is not the school-wide teaching responsibility named by LAC.

• “Subject-matter experts” refers to specialists in particular disciplines, whereas LAC applies to teachers across all school subjects.

• “Language specialists” refers to teachers with specialized language-training roles, while LAC extends language support beyond that specialist group.

Result

Thus, in the LAC approach, language education at school is the responsibility of all school teachers.
