However, the promise Over at by for from in of out throughout a trip somewhere nice could encourage students to try harder and do better Over at by for from in of out throughout school. Researchers Over at by for from in of out throughout the University Over at by for from in of out throughout Bristol (in England) and the University of Chicago ( Over at by for from in of out throughout the USA) looked Over at by for from in of out throughout how promises of cash and tickets to events affected students' studying and learning. Over at by for from in of out throughout 10,000 pupils in took part Over at by for from in of out throughout the research Over at by for from in of out throughout the year 2012. There was an improvement in classwork and homework, but this did not result Over at by for from in of out throughout better test scores.
