ABSTRACT: The present study seeks to explore the development of sociability in educational spaces through increasing opportunities for social interaction in public buildings, particularly in their shared spaces. The hypothesis is that human, activity and environmental factors stand in a significant relationship with sociability of the students at the School of Art and Architecture. Underlying this study is a descriptive-analytical methodology that was applied, in form of a case study, in the School of Art and Architecture of Bu-Ali Sina University. In so doing, a survey was performed by administering a questionnaire to the subjects, i.e. sample students from among the entire population of the students at the school. The correlation of the data was then analyzed by SPSS software and influence of each variable, on the development of sociability in educational spaces, was determined. According to the findings, from among the three variables, the psychosocial characteristics of the users, which tend to be the most influential and physical features of the public environment, are the least influential factors .Also the results of correlation tests show that psychosocial factors and physical factors are directly correlated with activity-related factors.
