In this tecnology information era, it is hoped that all teachers in Indonesia can be able to speak English, as an international language. There must be no excuse for them not to speak English anymore. Why do I say that?
Firstly, they have had basic knowledge of English. They started studying English when they were at junior high school, at senior high school, lastly they studied on the the first semester at University. If they want to study English again they just review the English lesson which they had got before. It will be easy for them to review, and they can practise their English well.
Secondly, the teachers often listen to English songs, through listening the songs, they can say or sing the songs continously, their English will be improved gradually.
Thirdly, browsing internet is a good technique in learning English. There a lot of English websites which provides topic of english grammar, conversation, vocabularies of English, English reading texts, English learning with You tube. Some of the webs can be downloaded in free of charge. So,the teachers can speak English fluently, if they studying it hard and seriously.
Fourthly, while they are studying English theirselves they can ask their coleages or friends who are English teachers, if they find difficulties in learning English.
Fifthly, if they do not want to study English, it means they create a boomerang for themselves, as their students can speak English while they had learned English whole years in their life. They will feel shy when teachers from other countries visit their school. How can they explain their school to the visiting teachers if they can bot master English.
Lastly,I suggest for all my Indonesian fellow teachers to start learning English again, there are a lot of facilities to support you such as internet, international television such as Indovision, Yes TV, First TV Media, English News papers like The Jakarta Post, Jakarta Globe, and Indonesia Media Online. No Excuse not to speak English for all Indonesian Teachers if you want Indonesia get more advanced country in the world.
