an objective method to assess teachers. Studies show that over time, test scores do not provide a【C1】______ means of separating good from bad instructors. Test scores are an【C2】______ indicator of quality because too many factors outside of the teachers control can influence student【C3】______ from year to year—or even from classroom to classroom during the same year. Often, more than half of those teachers【C4】______ as the poorest performers one year will be judged average or above average the next, and the results are【C5】______ as bad for teachers with【C6】______ classes during the same year. 【C7】______, theres a far more direct approach: measuring the amount of【C8】______ a teacher spends delivering relevant instruction—【C9】______, how much teaching a teacher actually gets done in a school day. This is hardly a new【C10】______. Thirty years ago two studies using this approach found that some teachers were able to deliver【C11】______ 14 more weeks a year of relevant instruction than their less efficient【C12】______. There was no【C13】______ to their success: it was obvious that the efficient teachers【C14】______ strictly to the curriculum, maintained stern discipline and【C15】______ non-instructional activities, like【C16】______ unessential classroom business when they【C17】______ focused on the curriculum. And both studies found that the teachers who【C18】______ more were also the teachers who【C19】______ students who performed well on【C20】______ tests.

As a general rule,American men earn more than American women． This holds true across industries, across education levels, and across states． But, theres at least one big【C1】______: part-time employees． In 2012, women who worked less than 40 hours a week generally out-earned men who spent the same【C2】______at their jobs． If they worked 35 hours a week, they earned about 11 percent mor

E．If they worked 25 hours a week, they earned about 4 percent mor

E．But once females hit that magic 40 hour【C3】______their relative pay declined dramatically． So why do women beat out men while working part-time and【C4】______out while working full-time My guess is that much of the explanation【C6】______down to two reasons: marriage and children． Women, including highly educated【C7】______, tend to cut their hours once they have families and children, especially【C8】______their husband has a higher salary． Men, meanwhile,are more likely to keep working a【C9】______week And so part-time women, as a group, are somewhat more likely to have gone to college,and【C10】______less likely to have dropped out of high school, than part-time men, who may well be working shorter【C11】______for lack of better options． The problem for women is that working part-time early in their careers can cost them salary while working full-time later in their careers,【C12】______lost experience and perhaps some【C13】______opportunities for promotions． Motherhood might be the most【C14】______job in the worl

D．But all too often, our economy still makes it【C15】______a career killer． So【C16】______part-timers, which other women out-earn men The BLS includes a job-by-job breakdown of the wage【C17】______, and among the nearly 150【C18】______with good-enough data to【C19】______, it found just two where females were better paid: counselors and health technicians． That said,as men look more toward those sorts of traditionally pink-collar jobs for employment, one has to【C20】______how long that pay advantage will last． 【C1】 A．problem
