When using "Module" as language the first line (in this case  #lang 
scheme) is
used to determine the language used. There is nothing wrong with using the
Pretty Big Language (and dropping the line #lang scheme), but since most 
programs
grow it is usually more convenient to use modules from the beginning.
Whether this is relevant for teaching purposes is another matter.
