Learning Bahasa Indonesia and its culture with more practice

I am a certified BIPA teacher, teaching Indonesian for foreigner. I teach Indonesian theoretically and practically. I ask students to practice Indonesian by taking them out to public area to find a good place to practice. For example, the students will be asked to order some food using Bahasa to a waitres or they will be asked to bargain vegetables or fruit. This will be very useful for the students to enhance their experiences in learning Bahasa Indonesia. Learning Bahasa Indonesia should be more fun and more practice.
