Experimental students grew aesthetically more than the controls. There was a floor effect among experimentals in the early years of the program: students who were 'overdue' for change - students in a beginning stage and the older grade - gained the most. Primary among the findings is that by the end of the program the experimental students were talking about art in ways comparable to most adult museum visitors. This means that students in the program, even at average ages eleven and thirteen, were thinking about art in ways that are typical of much older people who have self-selected to attend museums. The program also supported the growth of critical thinking skills, which transferred to non-art objects.
