Indonesia is so surprised, isn't? I write about this because my lecturers (English native speaker) pretty don't understand about Indonesian culture. Actually, It is very personal but let me tell you.
1. Let me know about you.
We are so exciting for having lecturer, a foreigner. Really we are. We like to know your background. You may not believe it but, a lecturer that I ever had, Mr. M, when we asking where he is from, he just answer 'somewhere'. What do you think? For me, It is annoying but we, I mean I, already understand this different culture.
Many Indonesian people may ask you "Where are you going?" and you begin to think 'mind your business'. Well, btw it is not really a question, it is let's say greeting. We are not really need a real answer. You don't have to say place where you go. So, don't be mad.
The second question that may also annoying is, "Do you have a shower?" or "Have a shower?". It usually for foreigner who live in society. I mean not in a hotel or like that. This question is also a greeting. It does not mean that you look messy or others. It just greeting! OK...
Back to the topic, please introduction yourself; your name, your coming to Indonesia, your view about Indonesia, your country, your experience of going abroad. It is a first key to get your students' heart.
2. Don't sit on the table. It is not polite even we will not be reprimanded.
3. Keep your tongue! You don't know if your students understand what you are talking, right?
4. Rubber time.
You may so boring with this, me too. In Indonesia, the toleration of being late is 15 minutes. (I think it will depend on situation and its personal). Actually, when I have a meeting or discussion with friends at 13.00, we will gather at 13.30. It is friendship matter but we can go on time (for some urgent). I don't know what happened but yes that's what happened. I know it so annoying but I also can not handle it. Just let it, because when you being harsh, they will keep more late. If you are on time, you will get respect. It will make your students try to on time. And in my mind that must be like that because you are a foreigner. And foreigner is not coming late. That's a stereotype that keep in my mind about foreigner.
5. Silent Voices
I don't want to tell about this. If you ask a question and you will likely find there is no question. It doesn't mean we don't understand. Just follow this
link.
6. Hurry Up!
We play slowly. If you ask your students to move or make a group. We will move slowly, or maybe about a minute have nothing but silent. You have to be patient. If you ask your students to coming to the class, we will pointing each other and again slowly. Usually your respond is "Come on!! What are you doing?"
7. Compliment
Don't give to much compliment. It will sound different. At least, in Java, if I say that's good it mean it is not good or there is something fishy. We know our capacity, so don't give too much.
What else?? Emh....smile is best make up. Do you have bad experience?
