In which instructional model is there no support in the first language (L1)?

The structured English immersion model is designed to immerse English language learners directly into an English-only environment where they receive content instruction primarily in English, without support from their first language. This approach aims to accelerate the acquisition of English by providing students with full exposure to the language in a supportive classroom environment where all instruction, interaction, and materials are delivered in English. The focus is on developing their language skills through direct engagement in the curriculum, which typically includes contextualized learning and interactive activities.

In contrast, other models like the grammar-based ELL pull-out and communication-based ELL pull-out often provide some level of support in the students' first language, allowing for the facilitation of understanding and retention of content. Submersion with primary language support implies that some assistance is available in the learners' first language, which can help them navigate the challenges of learning in a non-native language. Therefore, structured English immersion is characterized by its exclusive use of English without leveraging the learners' first language for support.
