About our authors
A native of Chile, Elizabeth Guzmán recently retired after a long teaching and administrative career. She directed Spanish language programs at several universities in the United States and supervised teachers of English in her country. Throughout her career, she designed face-to-face and flipped courses where Mosaicos, Unidos and Identidades were used, in addition to overseeing the design and implementation of online Spanish courses. She trained and mentored graduate teaching assistants and has served as a consultant to Spanish programs that were making the transition from face-to-face to flipped models of teaching. Teaching and learning have been at the center of her academic life, and she has shared her energy, passion and experience with undergraduates and graduate students. Teaching Spanish as a tool for communication to undergraduates taking Spanish courses to fulfill a requirement was one of the challenges that she undertook with love, understanding and determination during her career.
