Does not compute

Kids in the U.S. spend more hours in school (1,146 instructional hours per year) than do kids in the Asian countries that persistently outscore the U.S. on math and science tests — Singapore (903), Taiwan (1,050), Japan (1,005) and Hong Kong (1,013). That is despite the fact that Taiwan, Japan and Hong Kong have longer school years (190 to 201 days) than does the U.S. (180 days).

Anyone think this is right? I am not even considering cram schools...

Also, I would figure the biggest obstacle to a longer school year is not the students but the teachers and their unions.
