The Indonesian Way is a one-year course of study in basic Indonesian written by George Quinn (Australian National University). It has been adapted and fleshed out for open-access study online by Uli Kozok (University of Hawai’i).
The 100+ lessons in The Indonesian Way cover the basic vocabulary and grammar of formal Indonesian as it is used in everyday life. The lessons are rich in model dialogues, role play scenarios, and culture notes. Each lesson is illustrated in colour and comes with click-on vocabulary cards, audio files and many interactive exercises.
You can study The Indonesian Way alone, or use it as a text for classroom study under the direction of a teacher.
