A series of comparative analyses were carried out, revealing that the majority of the participating students perceived 25-30 as an optimum size for one class. Also, students in a relatively smaller class tended to show higher levels of satisfaction with school lives and with school and classroom facilities, more positive attitudes towards classroom atmosphere, and greater needs for peer interaction than did their counterparts. Furthermore, it was found out that the actual class size had to do with the students' perceptions of the relationships between school facilities and their levels of stress and pleasure at school.
