Campus open spaces play an important role in meeting socialization and personal development needs of youth. Various studies have shown that space use of youth is different from that of general society: particularly their psychosocial nature and the activities they carry out toward this nature differ from those of the children and adults. However, only a limited number of studies have produced findings on the needs of youth toward obtaining gains related to development of psychosocial nature required to carry out the activities aimed at meeting such needs. This study analyzed the use of campus open spaces by youth. The most preferred 3 places in study area have been chosen, and with behavioral observation, the activity types occurred in these places were identified. Which of these activities are for personal development and which of them are for social development were determined.
