4. WHAT IS THE ROLE OF THE STUDENTS' NATIVE LANGUAGE?
The habits of the students' native language are thought to interfere with the students' attempts to master the target language. Therefore, the target language is used in the classroom, not the students' native language. A contrastive analysis between the students' native language and the target language will reveal where a teacher should expect the most interference.
Students errors are to be avoided if at all possible through the teacher’s awareness of where the students will have difficulty and restriction of what they are taught to say.
