Created by the continuous feedback of a "student-tested, faculty-approved" process, HDEV4 traces development from infancy through late adulthood through a visually-appealing print component complete with tear-out review cards for students and class prep cards for instructors. Additionally, HDEV4 includes an online study center offering with CourseMate that includes an eBook and set of interactive digital tools to address multiple-learning styles, all at a value-based price. HDEV4 was developed with considerable input from focus groups, surveys, and conversations with students and instructors resulting in high-interest and comprehensive content, current examples, and a personal tone that accommodates sociology students' lifestyles and is proven to increase retention and enhance outcomes.
