The US Department of Education conducted two studies which looked in to the usefulness of computer software to improve student's math and science skills. The first recently released report found no evidence of improvement in the children's math skills after using the software. The study involved 33 districts and 132 schools.
The second report from the study will look at the effects of individual products and determine whether reading and mathematics software is more effective when used by teachers who have more experience teaching with the programs.
