"the central role of language in education, not only as a subject in the curriculum, but also as the medium in which the learning and teaching of all subjects in actually carried out" (Wells 1997 cited in Huang & Morgan, 2003, p. 235)

"The pressures are perhaps greatest for secondary students who are newcomers to an English-speaking academic environment, because they have relatively little time in which to master the sophisticated academic English, literacy skills, and subject matter needed to graduate and to make decisions about their future career paths." (Duff, 2001, p. 104)

"Because much of school language is context-reduced, English language learners often find themselves in a world of meaningless words." (Stoddart, et al, 2002, p. 666)

"The relationship between science learning and language learning is reciprocal and synergistic. Through the contextualized use of language in science inquiry, students develop and practice complex language forms and functions. Through the use of language functions such as description, explanation, and discussion in inquiry science, students enhance their conceptual understanding." (Stoddart, et al, 2002, p. 667)

"The critical point is that language processes can be used to promote understanding of content across all subject matter domains, and that language use should be contextualized in authentic and concrete activity." (Stoddart, et al, 2002, p. 684)

"CBI can be enriched through an understanding that language and content are never separate, that content in school contexts is always presented and assessed through language, and that as the difficulty of the concepts we want students to learn increases, the language that construes those concepts also becomes more complex and distanced from ordinary uses of language." (Schleppegrell, 2004, p. 67-68)

"It is not just that the words are different; the way the grammar is deployed and the grammatical choices that realize the texts of advanced literacy are different from the English language that students learn as they enact their daily lives. (Schleppegrell, 2004, p. 68)
