Well, if we're doing stylistic suggestions... :-)

class Student
         attr_accessor :name

         def initialize(name)
                 @name = name
         end

         def to_s
                 return "Name: #{@name}"
         end
end

attr_accessor is an easy way to set up a read/write instance variable; 
it creates an accessor method so you can go  object.name = "John Smith"
or  puts object.name

There's also attr_reader to set up a read-only field, and attr_writer 
for write-only.

The to_s method is the standard method used to convert an object to a 
string; so if you define it to be something sensible, you can just print 
or puts the object directly.

So, we can now do

s = Student.new("John Smith")
puts s
s.name = "John P. Smith"
puts s.name
