This course is designed with one primary goal in view: to encourage and lead the learner to communicate in Navaho in and out of class. Each of the 13 units has a "preparation stage" which consists of a self-instructional program on various grammatical points together with other activities for the student preparatory to meeting with the instructor or coming to class. These preparatory activities include written exercises, short dialogs, vocabulary, and survival expressions. Following the preparation stage is the "core stage" in which material is presented by the instructor in short question-answer exchanges called micro-wave cycles (Stevick, ED 012 897). This stage provides for supervised application and active use of the material introduced in the preparation stage. By means of these drills it is hoped that the student can attain a state of overlearning, which he will then maintain by the continued review and use of the material. The introduction to the course consists of (1) prolegomena to Navaho study, (2) presentation of the sounds of Navaho (tape-program), and (3) rules for reading and writing. The taped materials are available at cost from Brigham Young University, Provo, Utah 84601. (DO)
