According to Kobe University, the ages were divided according to the year when the course of study was changed, and the learning situation of science and mathematics subjects in high school and the number of patent applications after becoming an engineer were analyzed by age group.

　As a result, there is a big difference in the number of patent applications and renewals between the generation under 3 years old who has 700 hours of science and mathematics lessons and the generation above 47 hours of lessons. It turned out that there was.
It was also shown that the number of hours of science and mathematics classes in junior high school correlates with the degree of skill in physics and mathematics in high school, and that those who are good at physics and mathematics have relatively higher research results.The research group believes that the revised course of study and the reduction of time for science and mathematics classes have led to a decline in Japan's R & D capabilities.

　It has been pointed out that Japan's R & D capabilities have declined, as the number of patent applications has decreased in recent years. The fact is that the number of engineering papers per person is also being separated from the world's top level.Moreover, the supply of domestic R & D developers is declining due to the student's departure from science.
There were many voices citing the revision of the course of study as the cause, and it was required to verify the influence of the revision of the course of study.
