10 factors that influence school grades

Stephen Levitt is called a dissident economist, probably because he uses the economy incorrectly: not in order to build a business or take corporate profits. In the book Freakonomics, co-authored by journalist Stephen Dubner, he examines everyday life from an economic point of view. It turns out that if you study subjective categories from this perspective, such as parenting, everything that used to seem obvious is turned upside down.

There are a great many books on parenting. It would seem that it could be easier - buy any and follow the advice of experts. The only problem is that there are a lot of these books - as many as “expert” views on education, which often completely contradict each other. People like simple solutions. Books in which the author argues for a long time that parenting is a complex and multilateral process are sold worse than the conventional “5 simple rules on how to be a super mom”. There is, of course, no universal recipe for being ideal parents. And all this, in general, they understand, but still hope to find it in the next book.

The book by Stephen Dubner and Stephen Levitt, Freakonomics, was published by Mann, Ivanov and Ferber in 2011.
Steven Levitt does not offer such a recipe either. Moreover, he even questions the very need to strive for the ideal and tries to find out what parents can really do for their child, and on which nothing depends on them.

To study, he chooses the child’s success rate that is easiest to objectively measure - school grades

Without claiming a place among experts in education, the authors of "Freekonomics" turn to the usual data format for economists - statistics. Their findings can make parents worried who believe that their child will certainly succeed if they do everything “as expected”.

For example, we are used to thinking that studying at a high school or high school is the key to successful graduation. And this is the first belief that Levitt debunks. In fact, he says, the percentage of graduates with high scores in schools that are considered the best is so high, mainly because children who are initially motivated to study go there.

“Choosing a school doesn’t matter,” says Levitt, relying on the results of a study in Chicago, where the selection of students for high-level schools at that time was based on a lottery: all students who want to leave the district school to a better one, received equal random odds. Comparing the test results of children who managed to change schools and those who remained in the old, he noted that winning or losing the lottery almost did not affect their performance.
