The 4th R: Teaching about religion in the public schools
The Social Studies
Historically, public education has failed to find a constitutionally and educationally sound role for religion in schools. Dever et al assert that the main reason for teaching about religion is to help children to understand beliefs other than their own and to explore the role of religion in shaping the US and other cultures.
