According to Coa (2011), some factors are related to the teachers and their classes. In some cases, teachers’ lack of support and personal attention for learners may cause them feel anxious. Teachers’ inappropriate model of teaching, lack of knowledge and information, correcting learners’ mistakes in front of the class, lack of encouragement may create stressful atmosphere.
