19.Recently we asked how you feel about calculators in school.We heard from about thirty people in twelve countries,including a large number of Chinese.For example,Turbo Zhang writes,"My brain is rusting (生锈).Why?Because I use calculators everywhere,on my mobile phone,on my computer,etc.New technology makes us use everything except our brain."Yes,calculators can provide us with an answer,but we may not understand it completely.Just as a student at an architectural and engineering college in China,Zhao Jingtao,says,using a calculator is"a kind of laziness".
Critics of using calculators in school,at least until high school or university,outnumbered supporters two to one.In their opinion,calculators affect badly the thinking ways of students because they don't need to make an effort to get a result.They should work out problems with some kind of pain without computers.Then they may come to appreciate the power of these sophisticated (精密的)machines.Also,it is good to use your brain because calculators are not always available.Heroin,a math teacher in Kurdistan--Iraq,says good math skills help in life.So he believes in solving problems with a pencil until high school.
But Wenbo from China says calculators reduce careless mistakes.When they were young they couldn't use calculators.But when entering high school,they have to solve a lot of math problems.They have to use a calculator.It makes their homework easier.So he insists,"The hand-held calculators has been important in my studies and even in my life."
And the education expert,Barnabas Nyaaba in Ghana,advises that"as we enjoy the use of calculators,let's be careful so that it does not have any bad effects on us."
