The Second Edition release of the only program designed to support the flipped classroom model includes enhanced and revised, class tested content, new video, a new, interactive eBook and instant real-time classroom analytics made possible by Learning Catalytics. Are you ready to join the Unidos revolution? When Unidos appeared in 2012, it ushered in a completely new way of organizing the first year course in Spanish. Incorporating the flip teaching model into its highly flexible approach, Unidos capitalizes on using technology so that valuable class time is focused on applying knowledge rather than on instruction-it literally flips the nature of what typically takes place in class and out of class. Instead of first learning in the classroom and then practicing learned material out of class, students will, with Unidos, learn outside of class and then apply what they have learned in the communicative environment of the classroom.
