摘要:This study sought to discern the difference between factors that are perceived demotivating by demotivated and motivated learners of English in Vietnam setting. Data gathered from a 27-item questionnaire survey of 147 EFL learners reveals seven factors perceived as demotivating by both groups: student-related factors (self-esteem, experience of L2 failure, lack chance to use L2 in reality, classroom atmosphere) and teacher-related factors (test outside lessons, teachers’ skill, teachers’ knowledge). Findings from this study also reveal that demotivated students perceived more demotivating factors and with higher intensity than motivated ones.
