You’re doing homework online for a science class. A question appears: Do newborn babies see the world in black and white? You don’t know the answer. Do you google it?

Searching online for the answer may get you a better grade on the homework. But it won’t necessarily help you learn. Researchers note that students who usually receive higher marks on the homework but lower test grades are much more likely to use the Internet for answers while completing their homework. With these findings in mind, the researchers are questioning the validity of homework as a useful learning tool.

Glass, a psychologist, discovered this from analyzing homework and the grades on tests that he gave college students who took his courses from 2008 to 2017. He gave his students a series of online homework tasks. In 2008, only around 3 out of 20 students performed better on their homework than on the exam. By 2017, more than half of the students performed this way. Glass wondered what caused this result. So he thought about what had changed over the 10 years. One big thing was the rise of smartphones. They existed in 2008, but were not common. Now almost everyone carries one. So it would be easier today to quickly go online and find the answer to almost any homework question. But students can’t use phones during an exam. And that might explain why they aren’t doing that well on the tests.

To test this, Glass and a co-author Kang asked students in 2017 and 2018 whether they came up with their homework answers themselves or looked them up. Students who tended to look up answers also tended to do better on homework than their exams.

In Florida, a group of parents known as “the break moms” has been fighting to pass a law guaranteeing the state’s elementary-school students at least 20 minutes of daily free play.

In a survey of school-district administrators, roughly a third said their districts had reduced outdoor play in the early 2000s. Disadvantaged kids have been the most likely to be shortchanged (克扣). According to a 2003 study, just 56 percent of children living at or below the poverty line had break, compared with 83 percent of those above the poverty line a similar disparity (差异) existed between black children and their white peers.

The benefits of break might seem obvious-time to run around helps kids stay fit. But a large body of research suggests that it also promotes cognition (认知). Many studies have found that regular exercise improves mental function and academic performance. And an analysis of studies that focused specifically on break found positive associations between physical activity and the ability to concentrate in class.

In one series of experiments, researchers controlled break start times. Some days children were let out at 10 am. and other days at 10: 30. The kids attentiveness decreased when they had to wait longer for break and refreshed themselves after they played. And when fourth-graders in a break-free school were given a weekly break. Another group of researchers found that they had an easier time staying on task and were much less restless. These experimental findings are supported by an analysis of 10,000 questionnaires filled out by third-grade teachers: Even a single 15-minute daily break was connected with more-positive ratings of classroom behavior.

Perhaps most important, break allows children to design their own games to test their abilities, to role-play and to settle their own conflicts-activities that are key to developing social skills and managing complicated situations. Initial results from an ongoing study in Texas suggest that elementary-school children who are given four 15-minute breaks a day are significantly more sympathetic toward their peers than are kids who don’t get break.

【小题1】What causes "the break moms" to start a fight?

A.children behave better when let out earlier
B.kids waiting longer are unable to stay focused again
C.third-graders have difficulty in focusing on task
D.fourth-graders are more concentrated without a break
【小题3】What can we infer if we can ensure children a certain amount of daily break?
A.They escape from life conflicts.
B.They may strengthen dependence.
C.They are more considerate towards others.
D.They are eager to manage complicated situations.

Very few people look forward to and enjoy exams. That doesn’t have to mean that you should be afraid of them, though. The following tips will help you get through that terrible exam period.

Here are eight steps to help you during exams:

1.Make sure you know how much time you will have in the exam, and how many questions there will be. Then you can divide your time among the questions to make sure that they all get answered.

2.When you’re doing an exam that involves (涉及) long answers, it is a good idea to leave some space at the end of the answer so that you can add any extra comments that might come to mind when you reread your paper.

3.Don’t spend all of your time only on questions that you know the answer to because you will get a worse mark for answering some questions very well and some not at all.

4.It is worth taking a little extra time to make sure that your handwriting is neat. Then the examiner will be able to read it! Try to avoid spelling mistakes too!

5.The more prepared you are, the more likely you are to succeed.

6.Keep calm. If you feel yourself getting worried, take a deep breath.

7.Don’t try to discuss the exam after you’ve finished it. If you’ve got different answers from your friends, there’s no point worrying about it.

8.Once an exam is over, just forget about it. There is nothing more you can do about it. The best thing you can do is to go home and prepare for the next one.
