This edited volume provides a rationale for and classroom examples of the effective use of content-based instruction in English-as-Second/English-as-a-Foreign-Language (ESL/EFL), in which the study of an academic subject is sustained over time. Each chapter provides the following: detailed course descriptions; practical suggestions for developing content-based curricula; sample units of sustained-content courses; methods and materials such as exercises, study aids, and charts for integrating skills into content areas; classroom activities and assignments; examples of challenges facing teachers and students; excerpts of student accomplishments; and assessment measures. The text provides teachers with a sense of the possible applications of sustained content-based instruction and helps them design courses that will prepare their students for future academic success.
