Isn it important to teach the controversy between ID and evolution?
Yes, but not in a science class and not in a way that takes time away from teaching evolutionary biology. It’s clear that many people do not understand evolution, and that may be linked with the too little time it is given in the classroom. We need to teach the distinction between science as rational inquiry and religion as faith in history of science or philosophy classes, so that people appreciate the difference between science and religion and can make informed choices.
