Those with fixed mindsets(观念），as Professor Dweck says,believe that people are good at something-either good at math or music.For those people,mistakes serve no purpose but to highlight failure.Those with growth mindsets believe that some people are better or worse in certain areas but we can all improve and develop our skills and abilities.They are much more likely to be able to accept mistakes because they know they're part of learning.

This doesn't mean,of course,that we can all be world-class chess players,but rather that we all have a much greater ability to develop our potential than we think we do.It takes hard work, however,and we can't do it without taking chances and making mistakes. 

I know a group of fourth-grade and fifth-grade teachers in New York,who,inspired by the idea that children need to learn to make and live with mistakes,are developing their own lesson plans to help students examine the ideas of effort,and learn to take risks and accept imperfection and be willing to sit with the uncertainty of not knowing.

It's a big task.But over time,I think we can teach students how to change their idea at least slightly,so they look at mistakes as a very helpful part of learning.

According to the passage,why are many students afraid of making mistakes?

A.Because a miss is as good as a mile.

B.Because time and tide wait for no man.

C.Because results are more important than process.

D.Because early mistakes are the seeds of future trouble.
