5．Adding math talk to story time at home is a winning equation for children's math achievement，according to a new research from the University of Chicago．The study from psychologists Sian Beilock and Susan Levine shows a marked increase in math achievement among children whose families used Bedtime Math，an iPad app that delivers engaging math story problems for parents and children to solve together．
Even children who used the app with their parents as little as once a week saw gains in math achievement by the end of the school year．The app's effect was especially strong for children whose parents tend to be anxious or uncomfortable with math．
Previous research from this group has demonstrated the importance of adults'attitudes about math for children's math success．For example，a recent study found that math-anxious parents who help their children with math homework actually weaken their children's math achievement．
The new findings demonstrate that structured，positive interactions around math at home can cut the link between parents'uneasiness about math and children's low math achievement．
"Many Americans experience high levels of anxiety when they have to solve a math problem，with a majority of adults feeling at least some worries about math，"said Beilock，professor in Psychology and author of Choke，a book about stress and performance．"These math-anxious parents are probably less likely to talk about math at home，which affects how competent their children are in math．Bedtime Math encourages a dialogue between parents and kids about math，and offers a way to engage in high-quality math interactions in a low-effort，high-impact way．"
Study participants included 587 first-grade students and their parents．Families were given an iPad installed with a version of the Bedtime Math app，with which parents and their children read stories and answer questions involving math，including topics like counting，shapes and problem-solving．A control group received a reading app that had similar stories without the math content and questions related to reading comprehension instead．Children's math achievement was assessed at the beginning and end of the school year．Parents completed a questionnaire about their nervousness with math．
The more times parents and children in the math group used the app，the higher children's achievement on a math assessment at the end of the school year．Indeed，children who frequently used the math app with their parents outperformed similar students in the reading group by almost three months in math achievement at year's end．

18．

Old people are easy to feel lonely because their children are busy with their work and have little time to spend with them．Most of them have to be companied by pet dogs．However，it is sometimes impossible for some old people to keep pet dogs because they are too old or ill to take care of pet dogs．
Experts are studying the influence of robotic dogs on old people's depression（忧郁症），physical activity，and life satisfaction．Researchers are placing robotic dogs in the homes of lonely old people to see whether they can improve the quality of life for old people．Alan Beck，an expert in human-animal relationship，said，"Old people should be more active，challenged，excited．The problem is how we promote that，especially for those without friends or help．A robotic dog could be a solution．"
In the study，the robot，called AIBO，is placed for six weeks in the houses of some old people who live alone．These old people will keep a diary to note their feelings and activities before and after AIBO．Researchers will collect basic data for six weeks．Then，the researchers will review the data to decide if there are any changes in the life of its owner．
"I talk to him all the time，and he responds to my voice，"says a 70-year-old lady．"When I'm watching TV，he'll stay in my arms until he wants down．He has a mind of his own．"
The AIBOs respond to certain orders．The researchers say they have some advantages over real dogs，especially for old people．Often the elderly are disabled and cannot care for an animal by walking it or playing with it．A robotic dog needn't any exercise and feeding concerns．
"At the beginning，it was believed that no one would prefer the robotic dog because it was metal and not furry （毛茸茸的），"Beck says．"But it's amazing how quickly we have given up that belief．"
Hopefully，these robotic pets could become a more valuable health helper．They will record their masters'blood pressure，oxygen levels，or heart rhythms．AIBOs may even one day have games that can help exciting older people's minds．

A．their children don't like to stay with them
