Disadvantaged Students
One consistent pattern in our results is that the benefits of a school tour are generally much larger for students from less-advantaged backgrounds. Students from rural areas and high-poverty schools, as well as minority students, typically show gains that are two to three times larger than those of the total sample. Disadvantaged students assigned by lottery to receive a school tour of an art museum make exceptionally large gains in critical thinking, historical empathy, tolerance, and becoming art consumers.
It appears that the less prior exposure to culturally enriching experiences students have, the larger the benefit of receiving a school tour of a museum. We have some direct measures to support this explanation. To isolate the effect of the first time visiting the museum, we truncated our sample to include only control-group students who had never visited Crystal Bridges and treatment-group students who had visited for the first time during their tour. The effect for this first visit is roughly twice as large as that for the overall sample, just as it is for disadvantaged students.
In addition, we administered a different version of our survey to students in kindergarten through 2nd grade. Very young students are less likely to have had previous exposure to culturally enriching experiences. Very young students make exceptionally large improvements in the observed outcomes, just like disadvantaged students and first-time visitors.
When we examine effects for subgroups of advantaged students, we typically find much smaller or null effects. Students from large towns and low-poverty schools experience few significant gains from their school tour of an art museum. If schools do not provide culturally enriching experiences for these students, their families are likely to have the inclination and ability to provide those experiences on their own. But the families of disadvantaged students are less likely to substitute their own efforts when schools do not offer culturally enriching experiences. Disadvantaged students need their schools to take them on enriching field trips if they are likely to have these experiences at all.
