The January, 2015 release of this best-selling program includes a new, interactive eBook, a new cultural video, online vocabulary tutorials, dynamic study modules, and instant real-time classroom analytics made possible by Learning Catalytics. There are many ways to be a highly successful instructor of Spanish. ?Arriba! not only recognizes this fact but it informs an integral aspect of its approach: a rich, complete, and highly flexible communicative language program that provides latitude for individual instructors to teach the course in different ways within a wide variety of academic settings. Each instructor can "speak" in their own voice their own unique style and be certain that with ?Arriba! students will have a successful and rewarding learning experience. It is hard, if not impossible, to be reductive when talking about a program as rich and complete as ?Arriba!, however, if we were to name a second aspect of ?Arriba!, now in its Sixth Edition, that has contributed to making it an undisputed best seller, it would be the clarity and strength of its grammar presentations combined with activities that develop cultural insight and strong communication skills. The end result: a supremely solid approach that is easy to use and implement.
