Professor Shelley Hymel:

I agree with that but I would also suggest that within the universal programmes, there should be what I refer to as "repetition with variation". For example, we can have programmes or activities that focus on sexual identity and others that focus on racial identity.

These things have to be repeated in different ways because you reach different children with different approaches. The more diversity we have in our programmes, activities and lesson plans, the more we are likely to hit different things that children will find relevant to their particular experiences.
