Hi Christine, a teacher needs to use a variety of methods to teach a language ranging from students learning basic grammar and vocab to listening to music, poems, podcasts. Watching films with subtitles is also helpful. Here is a useful website http://www.italki.com/knowledge/page/TEACHING%20ENGLISH%20AS%20A%20SECOND%20LANGUAGE.htm

I think a teacher should lead the students to do something and say something, using the language. It's important for the students to practice with different ways.

I didn't understand your question. What do you want to know?

Hi christine, A teacher should first understand the students, because everyone different from others, so depend on that the different techniques should be followed in educating them.
