Well most of the god-tards have moved on from disputing that things evolve. Rather their new shit is intelligent design, which says that god works behind the scenes, controlling how things evolve and change. So they aren't disputing the fact that change happens, they are disputing the theory as to why.
However their counter is not a theory, since there is no way to test it, and hence has no place in science class. Even if it is right, it is not science as it is not something one can test. Any time you mention god, by definition outside of the universe and untestable, you aren't talking science.
Within the Creation movement, nobody with any idea what they were talking about has ever disputed that evolution does occur. They do not believe that all life evolved from a single common ancestor, but they do believe that all life evolved from whatever Noah was able to fit on the Ark some 4,000 years ago.
You are absolutely correct that Intelligent Design is not a scientific theory, and has no place in a science class. ID is a philosophy that says "this couldn't have happened without supernatural intervention," but it offers no testable alternative. By definition, anything supernatural falls outside the realm of empirical science, which deals only with the natural world. There is no way to test God, because God can simply choose not to participate in your test.
However, before there was ID there was Creation Science, which begins with the premise that the Bible is an accurate (though incomplete) historical account of how the universe and everything in it came to be. If you start from that hypothesis, there's all sorts of testing that can be done. You can propose a theory to explain some aspect of the world around you which is consistent with the Bible, test to see if your theory holds water, and change your theory when the evidence proves it false. In some cases you can even make predictions based on your theory, and find out later if your predictions came true. And the great thing is, it doesn't matter if the Bible is actually true or not - even if your hypothesis was based on a fantasy, the results are still based on observation.
So, does that belong in a science class? I think it's at least worth a mention.
