The TWI model provides integrated instruction for native English speakers and native speakers of another language, with the goal of promoting high academic achievement, first and second language development, and cross-cultural understanding for all students. In TWI programs, language learning takes place primarily through content instruction. Academic subjects are taught to all students through both English and the non-English language, which is usually Spanish. As students and teachers work together to perform academic tasks, the students' language abilities are developed along with their knowledge of content-area subject matter.
Most programs start at first or second grade.
While there is a great deal of variety with regard to program features of TWI programs, there are also some important core similarities. In this way, all students have the opportunity to be both first language models and second language learners. Furthermore, TWI creates an additive bilingual environment for all students since the first language is maintained while the second language is acquired.
