I'm not there, we have less of a problem here (but still some).
The problem is two-fold:
1) there is an aggressive anti-evolution, anti-science -- anti-reason campaign. It is not enough to just teach a smattering of evolutionary biology as if it is being imprinted on a blank slate of a mind. There needs to be a recognition of the need to start by countering the misinformation before trying to impart real information.
2) There is very little taught of a moderately complex topic.
This is partly because of the political pressure, partly due to lack of knowledge and time.
