Spy der Mann writes "An interesting study made by to two Penn State researchers shows that increases in homework may actually hinder educational achievement (Coral Cache) instead of improving it. The researchers analyzed a large amount of data collected by the Third International Study of Mathematics and Sciences (TIMSS) in 1994 from schools in 41 nations across the fourth, eighth and 12th grades. For some analyses, they used data from an identical study carried out in '99." From the article: "An unintended consequence may be that those children who need extra work and drill the most are the ones least likely to get it. Increasing homework loads is likely to aggravate tensions within the family, thereby generating more inequality and eroding the quality of overall education."
