The Workbook, by Alice. A Arana (formerly of Fullerton College) and Oswaldo Arana (formerly of California State University, Fullerton), continues the successful format of previous editions by providing additional practice with vocabulary and structures through a variety of input-based, controlled, and open-ended activities and guided compositions. Special features include the Prueba corta, preceded by a grammar self-check feature called A ver si sabe..., which allows students to quickly asses their knowledge of grammatical structures before completing the Punto final. The Perspectivas culturales (formerly Conozca...) section offers focused vocabulary and fact-based activities related to the same feature found in the student textbook.
