How much homework is 'right'?

A survey conducted by the United States Bureau of the Census (1984) found that public elementary school students reported spending an average of 4.9 hours and private school elementary students 5.5 hours a week on homework. Public high school students reported doing 6.5 hours and private school students 14.2 hours. Recent research studies by the Brown Center on Education Policy concluded that the majority of U.S. students (83% of nine-year-olds; 66% of thirteen-year-olds; 65% of seventeen-year-olds) spend less than an hour a day on homework, and this has held true for most of the past 50 years. In the last 20 years, homework has increased only in the lower grade levels, where it least matters (and indeed, may be counterproductive).

In America, NEA and the National PTA recommendations are in line with those suggested by Harris Cooper: 10 to 20 minutes per night in the first grade, and an additional 10 minutes per grade level thereafter (giving 2 hours for 12th grade).

In Britain, the Government has laid down guidelines, recommending that children as young as five should do up to an hour a week of homework on reading, spelling and numbers, rising to 1.5 hours per week for 8-9 year olds, and 30 minutes a day for 10-11 year olds. The primary motivation for the Government policy on this seems to be a hope that this will reduce the time children spend watching TV, and, presumably, instill good study habits.

TIMSS found that students on average across all the TIMSS 1999 countries spent one hour per day doing science homework, and 2.8 hours a day on all homework (the United States was below this level). On average across all countries, 36% of students reported spending one hour or more per day doing science homework.

There is some evidence that the relationship between time on homework and academic achievement may be curvilinear: pupils doing either very little or a great deal of homework tend to perform less well at school than those doing 'moderate' amounts. Presumably the association between lots of homework and poorer performance occurs because hard work is not the only factor to consider in performance -- ability and strategic skills count for a great deal, and it is likely that many very hard-working students work so long because they lack the skills to work more effectively.
