In my opinion, there are not only one problem in students' poor performance. I think to promote students to perform well in study, Carol Dweck's Growth Mindset and Alfie Kohn's perspective which indicated problematic education system should go together. It is because no matter how teachers stress Growth Mindset and be motivational to their students, without good educational systems like those of Nordic Countries which promote their students to find their dreams and do not discriminate them by their grades.
