摘要:AbstractThe aim of this study was twofold: to investigate a) possible differences between boys and girls and b) within groups’ differences in regards to their general and modified behavior towards the involvement of schoolmates with disabilities, in their mainstream physical education classes. Participantswere 168 primary grade school children; 76 boys and 92 girls, between 10 to 12 years of age (M=11.15,SD=.70), who completed the Greek version of the Children's’ Attitudes towards Inclusion in Physical Education-Revised questionnaire(CAIPE-R). Results indicated only within groups differences; both boys and girls showed higher (more positive) modified behavior on collaborating with a school-mate with disabilityin the physical education lesson.
