Teach them programming in addition to that. Ideally, the students should have a minimal exposure to everything under the sun -- or at least, as much of it as is practical. An in-depth knowledge of specific fields shouldn't be required, but basic exposure is wonderful for showing people what they're interested in, as well as giving them an appreciation for what people do.
