The philosophical basis underlying language and content integration is that a child’s whole education is a shared responsibility distributed among all teachers. The integration of language and content involves the incorporation of content material into language classes as well as the modification of language and materials in order to provide for comprehensible input to LEP students in content classes. The former is often referred to as content-based language instruction; the latter can be referred to as language-sensitive content instruction. An integrated approach bridges the gap that often separates the language and the content classrooms. By utilizing an integrated approach, LEP students can begin academic studies earlier. Such an approach increases the understanding of subject matter by LEP students, which facilitates their academic success. At the same time, the LEP students are able to increase their proficiency levels in the English language. shared responsibility distributed among all teachers.
