## The right to do wrong

The right to make mistakes is a fundamental right for any learner. No skill can
be effectively learned without making mistakes. The most obvious example is when
one tries to learn how play on a musical instrument. First you hear awful sound,
then it gets better and if he stick with it, he gets to play. The same
thing should be when trying to learn math, but for some reason people get
nervous when they make math mistakes. Many people think that there is no room
for mistakes when learning or researching math. This attitude take the sandbox
out of the learner (or researcher) turning math interaction into a daunting
unpleasant task. When one starts to play he knows that he is making awful
strange noises, but he continue to play until he get the "right" sound, his ears
help him in getting to know when he got it. It seems that a math learner lack
"ears", therefore he cannot tell whether he is right or wrong, however this
assumption is simply wrong. The role of a good math teacher is to help student
to "grow ears" in other words math teacher must help their student to develop
skills that will allow him to criticize and evaluate his and others work. But unlike
music the "Math Evaluation Skill" or MES is ought to be developed while
learning. Some may say that musical hearing skills also developed in musicians
and this may be OK if one would like to continue the comparison, but the point
is that math teachers are unaware of the importance of mistakes when they teach
the subject.
