The other problem can be attributed to the lack of control from educational system on teachers' activities in the
classes. Teachers neglect correct pronunciation of students and they don't employ proper method and technique in the
classroom. They don't involve students in free discussion by asking them to choose a topic. Teachers follow a traditional
model of instruction in their classes. They don't use a lesson plan and there is no interaction between teachers and
students. Actually they conduct their classes as teacher-centered classes. They play the major role in the class and they
considered student as passive listener in the class.
In relation with these findings Noora (2008) also found that the culture of teaching in Iran is teacher centered. In
order to learn vocabulary it was found that they try to learn vocabulary by translating texts into Persian and memorize
some vocabularies. They also try to learn new words by using a long list of words with their Persian equivalent without
contextualization. It is clear that these two techniques are popular in GTM method and it was found that they are not
effective techniques to improve vocabulary knowledge productively. Nunan (1999) also highlighted the inefficiency of
traditional techniques such as translation, and explanation in developing vocabulary knowledge since they cannot help
learners use language productively.
