more theory or more practice?

One English teacher has this dilemma on whether to teach her students more theory or give them more practice on the language.

I know that some teachers still follow the traditional approach of monopolizing class time with their talk or lectures. Not any more.

Today, modern-day language teachers only spend 10% of class time in presenting a lesson and giving feedback to her students. The rest of the time is spent in making the students use the language in various situations.

Usage is more important than theory. Knowledge of theory does not necessarily lead to effective communication. A good language teacher should spend more time in creating opportunities for her students to use the language in different situations.
