Language immersion is an educational approach where students are placed in an environment where they are surrounded by a target language. This method encourages learners to use the language in real-life situations, helping them to develop fluency and comprehension naturally. In a language immersion program, instruction is often delivered in the target language, allowing students to learn subjects like math or science while simultaneously acquiring language skills. This immersive experience can enhance vocabulary, pronunciation, and cultural understanding, making it an effective way to learn a new language.
