At Mountainview, our medium of instruction is English, yet our school is nestled within an Indonesian community. We offer our teachers limited language tutoring, and for those seeking a more immersive experience, additional intensive study options are available during the "summer" break. Regardless, any proactive steps you take to familiarize yourself with the language before your arrival will significantly enhance your overall experience!
Here are some resources to help you become familiar with Bahasa Indonesia.
Selamat Datang! (A free language course offered by the University of Victoria in Australia. This site gives you the opportunity to get acquainted with the Indonesian language and to do some interactive language exercises.)
kamus.net (Bahasa Indonesia dictionaries.)
