This transformational approach to teaching German, initiated in the fall of 1965, describes an experimental course at McGill University consisting of 156 hours spread into 26 weekly installments of one laboratory and five lecture hours. Detailed in this article are: (1) a priori claims concerning methods, (2) theoretical assumptions about learning and learning materials, (3) use of intuitive and explicit grammar in teaching German, and (4) tests. Extensive language sampling illustrates transformational theory. Pfeffer's word list (1964) and Chomsky's syntactic theory figure eminently in the program design. An extensive bibliography of general references and German transformational grammar is included. (RL)
