Teaching reading in K-12 content classes? As students progress from elementary to secondary school and beyond, the reading skills required to address the increasingly advanced and specialized subject areas can vary considerably. Students need to develop specialized literacies (relevant to each content area) as well as a critical literacy they can use across subject areas.This text book presents teachers, administrators, and researchers with a linguistic approach to teaching reading in different subject areas - an approach that focuses on language itself. Central to this approach is a view that knowledge is constructed in and through language and that language changes with changes in knowledge. This functional language analysis approach is shown using actual secondary social studies, science, and math textbooks and using a literary text.
