Educational Theorist: Recent editorials have called for limits on the amount of homework assigned to schoolchildren younger than 12. They point out that free-time activities play an important role in childhood development and that homework in large quantities can severely restrict children's free time, hindering their development. But the actual average homework time for children under 12-little more than 30 minutes per night-leaves plenty of free time. In reality, therefore, the editorials' rationale cannot justify the restriction they advocate.
