A new,first-of-its-kind study examines the connection between teacher burnout and students’ stress levels.Researchers from the University of British Columbia collected saliva (唾液) samples from over 400 elementary school children,grades from four to seven,at 17 public schools.Cortisol (皮质醇) levels were then assessed from the samples as the hormone is commonly used as a biological indicator of stress.Correspondingly,teacher burnout was determined through survey results.
Investigators found that in classrooms in which teachers experienced more burnout,or feelings of emotional exhaustion,students’ cortisol levels were elevated (提升).Higher cortisol levels in elementary school children have been linked to learning difficulties as well as mental health problems.The study appears in the journal Social Science & Medicine.“This suggests that stress contagion (蔓延) might be taking place in the classroom among students and their teachers,” said Eva Oberle,Ph.D.,the study’s lead author.
Indeed,the relationship between student stress and teacher burnout is a chicken and egg question.“It is unknown what came first,elevated cortisol or teacher burnout.We consider the connection between student and teacher stress a cyclical problem in the classroom.” Oberle said a stressful classroom climate could be a result of inadequate support for teachers,which may impact teachers’ ability to effectively manage their students.A poorly managed classroom can contribute to students’ needs not being met and increasing stress.This could be reflected in elevated cortisol levels in students.
Alternatively,stress could originate from students,who may be more challenging to teach because of increases in anxiety,behavioral problems,or special needs.In this case,teachers could feel overwhelmed and report higher levels of burnout.
“Our study is a reminder of the systemic issues facing teachers and educators as classroom sizes increase and supports for teachers are cut,” said Oberle.“It is clear from a number of recent research studies that teaching is one of the most stressful professions,and that teachers need adequate resources and support in their jobs in order to battle burnout and relieve stress in the classroom,” said University of British Columbia education professor Kimberly Schonert Reichl,Ph.D.,the study’s co-author.“If we do not support teachers,we risk the damage of students.”

According to most people,after a long period of studying or working,we need to have a rest to refresh ourselves.However,that may not be the case.According to a recent report,you don’t need the break as much as you may think that makes you feel less tired.
Scientists have long assumed that willpower is a limited resource,which is why you feel the need to have a rest,have a snack and then get back to task when you are feeling better.They argue that the only way it restores willpower is by rest,food or entertainment.
But psychologists have challenged this theory,saying weak willpower is all in your head.They have found that people’s belief in willpower determines how long and how well they’ll be able to work on tough mental exercise.“If you think of willpower as something that is not really used up,you can go on and on,” said Professor Veronika Job.
The researchers designed four experiments to test students’ belief in willpower.After a tiring task,those who believed,or were led to believe that willpower is a limited resource,performed worse on standard concentration tests than those who thought of willpower as something they had more control over.They also found that leading up to the final exam week,students who believed the limited resource theory ate junk food 24 percent more often than those who believed they had more control in resisting the temptation.
Mr.Job said,“The theory that willpower is a limited resource is interesting.Belief in willpower as a non-limited resource makes people stronger in their ability to work through challenges.”
The findings can help people who are battling against temptation.Willpower isn’t driven by a biologically-based process as much as we used to think.The belief in it is what influences your behaviors.

A new research shows that student strain often coexists with teacher exhaustion.(要点1)Students,who find their requirements unsatisfied as a result of teachers’ low-level management over class,may feel overwhelmingly stressed.(要点2) Conversely,teachers,who encounter great teaching challenge from students,tend to be burned out.(要点3) Therefore,more sufficient resources and support to teachers should be guaranteed,or students are likely to be ruined.(要点4)

Based on a recent report,having a rest to refresh yourself is not so essential as some people think.(要点1)Willpower,assumed to be a limited resource by some scientists,is thought to be only regained by rest,food,as well as entertainment.(要点2)However,this theory has been challenged.Researchers,including Veronica Jobs,conducted experiments and made some new discoveries.(要点3)If you believe that willpower is limitless,you will be more powerful,which is a potential help to resist temptation.(要点4)
