The present study employed naturalistic observations to compare bullying an
d victimization in the playground and in the classroom. The results indicat
ed that there were more opportunities to observe aggression and receive and
initiate aggression in the playground than in the classroom. The frequency
of bullying was higher in the playground (4.5 episodes per hour) than in t
he classroom (2.4 episodes per hour). The nature of bullying reflected the
constraints of the context (i.e. direct bullying was more prevalent in the
playground and indirect bullying was more prevalent in the classroom). Bein
g at the receiving end of aggression was more likely to occur in the playgr
ound as compared to the classroom. Nonaggressive children were more likely
to bully in the playground, whereas aggressive children were more likely to
bully in the classroom. There was no difference across context in the prop
ortion of episodes of reinforcement with peers present or in the rate of pe
er and teacher intervention. The results highlight the necessity of a syste
mic intervention programme that addresses not only the individual character
istics of bullies and victims, but also the roles of the peer group, teache
rs and the school.
