what's going on in the real world?
We face a question, it is an English paper infront of my eyes. No, it is, in fact, three paper in front of my eyes, I am good at handle question on it, but I am not quite good at that three paper. It’s seems that I always make mistakes while spread the small blackrectangle on the answer sheet1, it is frustrating. But why?
Deduction:
Vague Deduction: the mistake of makingmistake in one paper is x, then making mistake in two paper is 2*x(1-x) +x^(2),
Detail deduction:
the real deduction is the key part of this article which means that if we see the answer sheet as an information sources, two similarit resource will contain much more less information than one answer sheet which combined two answer sheet together, this can be proofd like this information equals to the negative value of entropy,
while make two answer the entroy have greatly increased,
information entropy =- pi*ln(pi),while the information equals to sum(pi*ln(pi)) ( the formate of the qq limitation is also frustrating)
then the information have declined which means that the two paper is not actually two paper. it contains much less informatin,and which of course lead more redudancy in paper use. which the result may is 1.4 between 1.5,( I need an math teacher,properly a very good one.this is just an evaluate value according to my experience of hundreds of math equations, to proove it is of some difficulty, my email address is [email protected])
Introspection:
if we make an exam that the examed information is much less than the informatin it contains. why we make two answeer sheet. just 1.5 contains will make the same result? why ? why we always stupid and blind to see that the infromation we see and actually use is very different from what's going on in the real world. I am nothing but an curious boy always make mistakes by accident or by design to see and to get a totally new perspective of the real world.
(Generally speaking,the information we use to exam the quality of the students is actually much less than the information it contained)
Part two:
Value Of Information (not equal to) Information Amount(which have many physical way to caculate like Shannon Entropy, or something else) =not=information leaved in our mind
Let't talk about what is between informatin value and the information leaved in our mind. ( they are basic concept and it's relflction in our mind, actually may be seen as something realted to us,which means that are not caculated by the equation of math but with the equations build in our mind)
why informatin
Anslysis of the paepr, real world analysis.Real world thinking.
When the number of the paper increase, (if the paper is independent (free) with each other’s.) we will finally makemistakes. (through this is not what actually happen in the real world, I haveheard from some excellent students who is good at doing exam have told me thatthey never make mistakes during this process, this kind of students is very rare,and actually very good)
Why we increase the number of answer sheet?As they can lead people to make more mistakes?
The way we thinking is very different from the decider of the policy with the user of the policy.
If we have two answer sheets and we have to finish one and then the another. (Maybe the paper is too long so the decide maker made this decision, which in fact is a big mistake and has been almost impossible to change in short time)
Small problem I have the habit of answerall the problem in the original paper and then spread it to the answer sheetwhich lead to me get zero grade in the level four English listening test. Why don’they give us five minutes to spread the answer on the original paper to theanswer sheet?
First this is an reform about five years, if there are five minutes to spread theanswer it will be quite easy to cheat on the exam science the level four examdo not have very serious checking procedure. As I assume there isa child making big cheat and make a great influence.only rare things will havecontain big information So the decision maker have a problem about cheat, thenhow to solve it? Yes it is very easy and indeed very efficiency.
(Original people think at an original waysometime something contain more information than it is in economic pay back.
Which leadpeople to make very bad decision. We change the exam procedure for it is noteasy to make cheat while at the same time we lost more money energy because of toomany mistakes is during this new procedure, because that when we applied to newprocedure there are always someone left to the past get mistake, this us to seethat new thing will make some change, and people will make mistakes this isnormal, what they didn’t see is thenature that we do will be more easy to make one system than other!!)
