Cognella Active Learning provides you with interactive learning activities, such as flashcards, quizzes, PowerPoint lectures, etc., while an ebook provides you with reading material only. A Cognella Active Learning environment will not contain the same information as a print or digital textbook assigned for your course. If your instructor has assigned Cognella Active Learning and a textbook, you must purchase both components for your course. Often, these components are provided as a bundle at a discount. If your instructor has assigned Cognella Active Learning and a textbook, the Active course will be free with purchase of the textbook from our website or as a new copy from your campus bookstore. If you purchase the textbook from a third-party, you will need to purchase access to Active Learning from our website.
