The lecture of Dr. Pawl Wadden let me think about the university. In the lecture, he told us that in Japan, it is difficult to enter the university and easy to graduate. On the other hand, in the U.S, it is easy to enter, however very hard to graduate. These differences are very interesting!
Japanese university students often play with their friends and don't study enough because they can easily graduate from college, just like elevators. Compare to Japanese college students, the college students in the U.S study very hard so as to graduate. Maybe that's the one of the reasons why American students are smarter than Japanese ones. So, I propose that the Japanese university should give students much homework and make the norm for the graduation more strict.
Now, Japanese educational system has to be changed. I think by comparing Japanese colleges with American ones, Dr. Pawl Wadden implied that we must study harder for being better students than the other countries students.
