Specially designed academic instruction in English
Specially designed academic instruction in English (SDAIE) is a teaching approach intended for teaching various academic content (such as social studies, science or literature) using the English language to students who are still learning English. SDAIE requires the student possess intermediate fluency in English as well as mastery of their native language. The instruction is carefully prepared so the student can access the English language content supported by material in their primary language and carefully planned instruction that strives for comprehensible input. SDAIE is a method of teaching students in English in such a manner that they gain skills in both the subject material and in using English.
SDAIE is not an English-only submersion program where the student is dependent solely on English, nor is it a watered down curriculum. SDAIE is an approach that seeks to teach both content and language in a cognitively demanding environment. As such, it is an important aspect of some structured English immersion programs. Lessons thus include both content goals and language goals for the students.
Preparing good lessons in SDAIE require awareness that the student is not a native English speaker and avoidance of those aspects of English that might make it difficult for a person learning English as a second language. This includes avoiding idiomatic English, which may seem natural to a native speaker but would confuse non-native speakers.
