SINCE it was first published more than a decade ago, Arriba! Comunicacion y cultura has been used successfully by thousands of instructors and hundreds of thousands of students throughout North America. Originally conceived to address the need for an elementary Spanish text that went beyond grammar drill to develop cultural insight and communication skills, it has come to be known as a highly flexible program--one that can be used effectively in a wide range of academic settings and by instructors with a variety of different teaching styles. Adopters have consistently praised it for its clarity and for providing materials that are both motivating and easy to use in the classroom. Highlights of the Fourth Edition Drawing on the success of previous editions, the fourth edition of Arriba! has been carefully crafted to educate another generation of students. Like its predecessors, the new edition has been designed as an eclectic and flexible text that is clear, easy to use, and motivating to students. But while the goals remain the same, many changes and refinements have been made as a result of extensive feedback from over a hundred reviewers. A new design enhances the clarity of the chapter structure, while other changes to the student text make it even more appealing and relevant to today's students. The comprehensive array of supplemental materials has also been carefully reviewed and revised, and several new items have been added to the program. Specific changes include the following: The chapter opening spread now serves as an advance organizer for the chapter as a whole, explicitly introducing the chapter's target country or region through photos, a locator map, and a proverb, in addition to providing an outline and identifying communicative objectives for the chapter. The vocabulary lists of Asi to decimos have been streamlined, with visuals added to provide context and motivate learning. The Aplicacion vocabulary and grammar activities now move more systematically from guided to open-ended activities. The new organization allows a gradual progression from receptive to guided productive to open-ended communicative activities, building student competence in steady increments. Cuanto sabes tu? self-assessment boxes at the end of each of the first two parts of each chapter remind students of the objectives set out in the chapter opener and assist students in determining how well they have mastered the material. The Comparaciones section, now at the end of the first part of each chapter, has been organized into two sets of activities: a pre-reading activity, En tu experiencia, in which students draw on their own experiences and a post-reading activity, En tu opinion, in which students express their opinions. A new video section, entitled Observaciones, appears at the end of the second part of each chapter. It enables students to integrate what they have learned both in the chapter and in the video through a series of pre-viewing, viewing, and post-viewing activities. Nuestro mundo, the third major part of each chapter, has been reorganized and expanded to include Panoramas, Ritmos, Paginas, and Taller. Panoramas: a visually stimulating presentation of the chapter's featured country or region, accompanied by activities that foster student engagement with the material. Ritmos: lyrics and listening activities to accompany a culturally relevant musical selection, with music available to instructors on a special CD entitled Ritmos de nuestro mundo. Paginas: authentic readings, building in length and complexity throughout the text and accompanied by pre-reading, reading, and post-reading activities.
