When the Ministry of Education, Culture, Sports, Science and Technology surveyed elementary and junior high school students nationwide for the first time, it was clear that 25 or less books accounted for 30%, while the larger the number of books, the higher the correct answer rate of the test. became.
In May, the Ministry of Education, Culture, Sports, Science and Technology conducted a "national academic ability test" for more than 2 million sixth graders and third graders nationwide, and is one of the indicators to measure the economic and cultural capital of households. For the first time, I investigated the "number of books in the home", which is also used in international surveys.
As a result, the number of books in the house was
▽ 0 to 10 for elementary school students 11%, junior high school students 14%
▽ 11 to 25 books for elementary school students 19%, junior high school students 20%,
less than 25 books The children who answered accounted for 30%.
▽ 26-100 books were 34%
for elementary school students, 32% for junior high school students ▽ 101-500 books were 32% for elementary school students, 30% for junior high school students
▽ 501 or more books were 5% for both elementary and
junior high
school students.
Looking at the correct answer rate of the academic ability test, in elementary school mathematics, there is a difference of 18 points between the child with the largest number of books and the child with the least number of books, and there is a difference of 15 points even in the national language of junior high school. Tended to be higher.
Ryoji Matsuoka, an associate professor at Waseda University, an educational sociologist, said, "It is significant that a large-scale national survey showed that there are differences in academic ability depending on the family environment, and we discuss policies based on the actual situation of children with difficulties. I want you to do it. "
