I knew English is the most important international language used by most people all over the world. I found out that I learnt that the quality of teachers has not been good enough. The most of Thai students have been to study English language more than 15 years. But they are also weak in English language. But did not to blame all the teachers because most of students are lazy to practice to do homework, they are lazy to review lesson when after class. They are rarely use the English in daily life so no chance to practice. Although they are lazy but speaking English is the most interest and students would like to improve the skill. So they are think if study English with a multi-cultural classroom will be speak English better.
