Structured English Immersion is described as which of the following?

• A. 1980s subtractive program teaching English only in a self-contained ESL classroom; content instruction is based on comprehensible input.
• B. A bilingual program with substantial native language use.
• C. Content-based ESL with co-teaching and hands-on activities.
• D. A reading strategy to improve comprehension.

Answer: (A)

Structured English Immersion is an English-only instruction approach that emerged in the 1980s. It aims to place English learners in a self-contained ESL setting where content instruction is delivered through comprehensible English, using supports like visuals, modeling, and scaffolding to make meaning clear. The subtractive aspect means native language use is minimized in the classroom, with the goal of rapid English acquisition through immersion in English.

This is why it fits best: it emphasizes teaching content in English with strategies to make the language understandable, rather than relying on bilingual instruction or a reading-specific strategy. The other descriptions describe bilingual programs, general content-based ESL with different collaboration, or a general reading tactic, none of which capture the English-only, 1980s-subtractive, comprehensible-input focus of Structured English Immersion.
