Overtly taught English pronunciation and listening skills; word building; word-order rules; a wide range of vocabulary (synonyms, antonyms, survival vocabulary, academic word groups); and formulaic expressions not easily explained by grammar analysis ("There you go again"; "What's up with that?"). The overt teaching of verb tenses is typically the anchor of many of these programs, accounting for up to one-fourth of the total instructional time.
6. Rigorous exit time lines. Usually one year. Should have the basics to succeed in class by then.
7. Federal mandates 2 year monitor of SEI grads. Should continue learning English in sheltered or mainstream classes.
