“…Various efforts are made to stimulate the development of children's social competence, one of which is by giving rewards in the form of praise, star symbol, or toy that can effectively improve children's prosocial behavior, which is, one of the indicators of social competences (Fabes, Fultz, Eisenberg, May-Plumlee, & Christopher, 1989). Besides, storytelling activities (Mincic, 2007), video games (Greitemeyer & Osswald, 2010), and lego games (Pang, 2010) are also proven to be an alternative to improve children's social competence. This form of stimulation is inseparable from the participation of parents and teachers to direct the children in developing their social competence, as evidenced by the research conducted by Berns (1997) that presents the involvement of teachers and parents as one of the successes of school programs.…”
