We cannot blame the schools alone for that dismal decline in SAT verbal scores. […] What happens at home really matters. And when our kids come home from school, do they pick up a book, or do they sit glued to the tube watching music videos? Parents: don’t make the mistake of thinking your kids only learn from 9 a.m. to 3 p.m. You are and always will be their first teachers.
