32、illion students across the nation will begin high school.Many willdo well.But many will not.Consider that nearly two-thirds of students will-experience the“ninth-grade shock,”which refers to a dramatic drop in a students academic performance.Somestudents cope with this shock by avoiding challenges.F

34、rge,because students experience of第6 页,共4 9 页transitioning(过渡)to the ninth grade can have long term consequences not only for the studentsthemselves but for their home communities.We make these observations as research psychologistswho have studied how schools and families can help young people thri

35、ve,C)In the new global economy,students who fail to finish the ninth grade with passing grades incollege preparatory coursework are very unlikely to graduate on time and go on to get jobs.Onestudy has calculated that the lifetime benefit to the local economy for a single additional studentwho comple

36、tes high school is half a million dollars or more.This is based on higher earnings andavoided costs in health care,crime,welfare dependence and other things.D)The consequences of doing,poorly in the ninth grade can impact more than students ability tofind a good job.It can also impact the extent to

37、which they enjoy life.Students lose many of thefriends they turned to for support when they move from the eighth to the ninth grade.One study ofninth-grade students found that 50 percent of friendships among ninth graders changed from onemonth to the next,signaling striking instability in friendship

38、s.E)In addition,studies find the first year of high school typically shows one of the greatestincreases in depression of any year over the lifespan.Researchers think that one explanation is thatties to friends are broken while academic demands arerising.Furthermore,most adult cases ofclinical depres

39、sion first emerge in adolescence(青春期).The World Health Organization reportsthat depression has the greatest burden of disease worldwide,in terms of the total cost of treatmentand the loss of productivity.F)Given all thats riding on having a successful ninth grade experience,it pays to explore whatca

40、n be done to meet the academic,social and emotional challenges of the transition to high school.So far,our studies have yielded one main insight:Students beliefs about change-their beliefsabout whether people are stuck one way forever,or whether people can change their personalitiesand abilities-are

41、 related to their ability to cope,succeed academically and maintain good mentalhealth.Past research has called these beliefs“mindsets(思维模式),”with a fixed mindsetreferring to the belief that people cannot change and a“growth mindset referring to the belief thatpeople can change.G)In one recent study,

42、we examined 360 adolescents beliefs about the nature of“smartness-that is,their fixed mindsets about intelligence.We then assessed biological stress responses forstudents whose grades were dropping by examining their stress hormones(荷尔蒙).Students who第7 页,共4 9 页believed that intelligence is fixed-tha

43、t you are stuck being“not smart if you struggle in school-showed higher levels of stress hormones when their grades were declining at the beginning of theninth grade.If students believed that intelligence could improve-that is to say,when they heldmore of a growth mindset of intelligence-they showed

44、 lower levels of stress hormones whentheir grades were declining.This was an exciting result because it showed that the bodys stressresponses are not determined solely by ones grades.Instead,declining grades only predictedworse stress hormones among students who believed that worsening grades were a

45、 permanent andhopeless state of affairs.H)We also investigated the social side of the high school transition.In this study,instead ofteaching students that their smartness can change,we taught them that their social standing-thatis,whether they are bullied or excluded or left out-can change over tim

46、e.We then looked at highschool students stress responses to daily social difficulties.That is,we taught them a growthmindset about their social lives.In this study,students came into the laboratory and were asked togive a public speech in front of upper-year students.The topic of the speech was what

47、 makes onepopular in high school.Following this,students had to complete a difficult mental math task infront of the same upper-year students.I)Experiment results showed that students who were not taught that people can change showedpoor stress responses.When these students gave the speech,their blo

48、od vessels contracted andtheir hearts pumped less blood through the body-both responses that the body shows when it ispreparing for damage or defeat after a physical threat.Then they gave worse speeches and mademore mistakes in math.But when students were taught that people can change,they had bette

49、rresponses to stress,in part because they felt like they had the resources to deal with the demandingsituation.Students who got the growth mindset intervention(干预)showed less-contracted bloodvessels and their hearts pumped more blood-both of which contributed to more oxygen getting tothe brain,and,u

50、ltimately,better performance on the speech and mental math tasks.J)These findings lead to several possibilities that we are investigating further.First,we areworking to replicate(复制)these findings in more diverse school communities.We want to knowin which types of schools and for which kinds of stud
