"Kaleidoskop" is essentially two books in one: a cultural and literary reader with a comprehensive review of grammar. This combination allows maximum flexibility for instructors to design their own programs. The 10 topics of the Lekture section contain a variety of texts and activities, and the 10 Kapitel of the self-contained grammar section (Grammatik) allow instructors to work with the grammar topics in whatever order they choose; the grammar chapters may be treated independently of the reading chapters or used concurrently with the Themen of the same number. Given these materials the instructor can provide a learner-centered classroom with activities that lend themselves to cooperative learning. "Kaleidoskop" features a flexible four-skills, learner-centered approach that promotes communication and focuses on the literature and culture of the German-speaking world. Reading plays an important role in this text, with exercises for listening, speaking and writing revolving around the wide range of authentic reading selections. These texts are authentic and include advertisements, charts, newspaper and magazine articles, letters, e-mails, forum mails, polls, interviews, biographies, songs, poems, and fiction.
