“but also the scientific evidence against it.”
As worded that means NOT teaching ID.
==Darwin’s theory of evolution and the scientific evidence that supports it
As worded that means NOT teaching Darwin’s fanciful creation myth.
It should include teaching enough about ID, so that students can say why it isn’t a scientific theory.
It helps to provide both examples, and non-examples to teach about any concept. If you wish to teach why evolution is a scientific theory — it would help to be able to distinguish it from theories you don’t consider scientific.
Please note, the above concerns pedagogy only — it isn’t meant to be a comment on the substantive issues (between evolution, and ID, etc.).
