U.S. education "utterly flat" in global assessment
Today in our School Matters series, we take a look at a report out this week that shows American students are lagging behind teens around the world in critical subjects. Every three years, 15-year-olds in nearly 80 countries take an international student assessment that tests math, reading and science. American teenagers scored worse than students in countries like China, Canada, Finland, and Poland in all 3 subjects, and they ranked below average in math. CBS News contributor and psychologist Lisa Damour joins "CBS This Morning" to break down the findings.
