Language Domain +1 Matrix is an instructional strategy that deliberately embeds language acquisition support throughout lessons. This systematic approach ensures the planning of specific supports for receptive (reading, listening, observing) and productive (speaking, writing, reproducing) language skills during instruction. The strategy helps identify key academic vocabulary, create multiple access points for content comprehension, and design structured opportunities for language practice. Intentionally planning these supports in advance creates an environment where language learners can meaningfully engage with content while developing their language proficiency in a scaffolded, supportive setting.
