Objective To compare the sharing behavior of children coming from two different education models,and provide some evidence for the prevalence of mixed-age education. Methods The study used the sweets,the toy car and the learning experience as three different things to be shared,and discriminated two different sharing objects-the younger children and the same-age children,with the subjects being sixty preschoolers coming from two different education models. Results There was no significant gender effect,but the effect of different sharing things was absolutely obvious(P<0.05).The mixed-age education children were more likely to share learning experience than toy car and sweets,while the same-age education children demonstrated a similar trend.Besides,the mixed-age education children were more willing to share with their younger partners,this effect was significant in the condition when they shared toy car(P<0.05). Conclusion Mixed-aged education could accelerate children's sharing behavior with their younger partners.
