Korean is the seventh most commonly spoken language in the U.S., and Korean heritage students - those with some proficiency in or a cultural connection to the language through family or community - outnumber others learning Korean at the college level. Many schools offer a separate heritage track for learning Korean, but until now there has been no textbook designed specifically for heritage or accelerated curriculum students. Integrated Korean: Accelerated 1 and 2 directly address the linguistic needs and abilities of heritage learners in a single academic year. Volume 1 presents lessons on thematically organized subjects, starting with familiar topics such as family, friends, daily routines, schoolwork, campus activities, dining out, and shopping. Volume 2 advances to more formal subjects beyond family and friends, such as travel, transportation, housing, holidays, lifestyles, careers, and Korean history and culture. Students approach the lessons with multi-level communicative classroom activities and reading materials with standards-based exercises and projects that not only address the particular language requirements of heritage learners, but also encourage them to participate more fully in their own family and community life. Each volume's textbook and workbook offer authentic conversations and texts in both informal and formal contexts, structured tasks, and a wealth of interesting and relevant cultural content.
