The new studies show that fewer than half of the 9th graders in many of the nation’s largest cities, can ever graduate. The studies clearly show that the dropout rate isn’t dropping. And, in particular, the dropout rate isn’t dropping for poor and minority students.

Amazingly, though so many regret the rising dropout rate, our schools continue to lack formal plans--or any plans--to teach students motivation(动机). Most schools have no game plan to ensure that students understand that school will be completely necessary. Schools expect youth and children to act as though school is important, but they never teach them to believe that.

Years ago, families ensured that the offspring recognized the value of school. But in many modern families, the children may fail to recognize the importance of school life just because these families may actually tell the child that school is not important. Since many families are not motivating their children to be interested students, youth professionals, like teachers may need to provide this training. Otherwise, it is likely the dropout rate will continue not to drop, but only worsen.

Here are some strategies to convince even the most apathetic (无动于衷的) students that they must stay in school.

Ask students if they will ever need to work: The world has changed. 100 years ago, factory work was the booming job, and it required no education. Today, factories are increasingly automated. Most computer-related jobs require education and at least a high school diploma.

Ask students which century they will be prepared for: In 1900, the most common jobs were farm laborer and domestic servant—education not needed. Now, the most common jobs are office and sales worker—education and diploma usually needed. An amazing 6 out of 10 people today work in a store or office.

Ask students to devise a way that the employee could be replaced. For example, the coming trend in fast food is to use computers rather than people to run the restaurant. A prototype is apparently already being tested. The students should discover that most jobs that lack education and diploma requirements may be ripe for automation.
