There are difficulties in setting regular, formal homework as primary children need supervision and help. I have no objections to general expectations that children should read regularly at home, learn times tables and spellings, engage in some research tasks or even prepare such things as a three-minute talk at home.
However, these should be set with reasonably long time allowances, ie half a term, or at least one week. My reasons are twofold: parents who work may not collect their children until early evening and then "quality" time together is vital; and children of this age often participate in group activities such as Cubs, Brownies, music, sports etc. which is vital when schools have to work so hard to cover the national curriculum.
The balance of a child's developmental needs, in terms of their family, social and academic requirements, should be carefully considered by the Government when planning to raise standards. I fully endorse the need for further controlled trials before the "more is better" policy commits every pupil to a homework regime without flexibility or understanding.
