I tell my Intro to Digital students to look at the LCD after each shot and do an analysis; you would be a fool not to use such a tool, especially when you are just learning to understand exposure. I also have them bracket so that they can analyze exposures on the computer as they really don't know what a good exposure is yet. As they become more fluid we add the Histogram to appreciate highlights and dark tones.
I watch new students develop terribly exposed or blank rolls or rolls of poor focus or DoF. I don't listen to that blue-collar attitude that shooting without the LCD teaches you...fill in the blank here. It is a waste of time and materials. The digital students after 1 semester far outstrip the film students in their ability to handle a camera. The folk who can teach anything but film refuse to admit that. We just got rid of one of those, thank goodness.
Film folk don't have that facility. If they did from the git-go, they would be fools not to use it. If you don't use it now because you have a zillion years of experience, well, more power to ya. If you don't want to use it for any reason (look ma, no hands) that is up to you. To decry such a method as chimping is being small and smarmy. I'm not impressed. Sneering is not an argument.
