In applying classical conditioning, there should be repetition and consistency with regard to the stimuli. If proper conditioning is implemented, the students will eventually learn to behave and learn properly.  Take for instance, a teacher has made it a daily habit that if she claps her hands 3 times, this means that the students should clean their surroundings. So even if the teacher does not say a thing but as long as she claps her hands 3 times, instantly, the children will make it sure to clean up their space. This will only be successful, if the activity or stimuli has been made a routine.
