• • Parents tend to be anxious about children’s brains and test scores
  • What matters in child’s life is not the skills school teaches mostly
  • GED- high school graduation exam
    • Class claimed to change people’s attitude in 2 months
  • If its true, why do we have schools
  • Is GED same as high school?
  • Farther investigation showed GED students performed slightly better than undergraduates, but didn’t perform as good as high school students
    • Performance in occupation, reading, success rates in college/marriage/military….
    • This didn’t show up in the test results, however
  • GED and high school, in terms of score/passing, its only cognitive ability
  • Non-cognitive ability affecting this?
    • Character
    • Self regulation, self consciousness, delaying gratification,  resisting impulse
  • Why testing?
    • • Testing can be showed in data form, while character is not quantifiable (cognitive)
      • Character testing is also expensive, and school runs on taxpayer money (non-cognitive)
  • Poverty is unhealthy environment that gives off stress to children, which in turn makes them perform less in school environment
  • Stress hormones distracts students from learning

      • Got arrested for punching a cop (assault of a police) when she was 15
      • Her mom didn’t want Kewauna to have the same life as her
      • Entered a program in high school that taught students non- cognitive skills
      • Her grades and SAT scores improved after learning the non- cognitive skills, eventually got accepted to University
  • Stress from family issues couldn’t be resolved with school
