This isn't related to super so much as it is the nature of inheritance and modules in Ruby. See this diagram:

If you want inheritance for singleton methods of an object from a module you must _extend_ the object with a module defining _instance_ methods.

For example:

module Foo
  def self.included(klass)
    klass.extend(ClassMethods)
  end
  module ClassMethods
    def bar; …; end
  end
end

class Bar
  include Foo
end

Bar.bar
