Design of the Study and School Tours
The 2011 opening of the Crystal Bridges Museum of American Art in Northwest Arkansas created the opportunity for this study. Crystal Bridges is the first major art museum to be built in the United States in the last four decades, with more than 50,000 square feet of gallery space and an endowment in excess of $800 million. Portions of the museum’s endowment are devoted to covering all of the expenses associated with school tours. Crystal Bridges reimburses schools for the cost of buses, provides free admission and lunch, and even pays for the cost of substitute teachers to cover for teachers who accompany students on the tour.
completely free to schools
Because the tour is completely free to schools, and because Crystal Bridges was built in an area that never previously had an art museum, there was high demand for school tours. Not all school groups could be accommodated right away. So our research team worked with the staff at Crystal Bridges to assign spots for school tours by lottery. During the first two semesters of the school tour program, the museum received 525 applications from school groups representing 38,347 students in kindergarten through grade 12. We created matched pairs among the applicant groups based on similarity in grade level and other demographic factors.
An ideal and common matched pair
An ideal and common matched pair would be adjacent grades in the same school. We then randomly ordered the matched pairs to determine scheduling prioritization. Within each pair, we randomly assigned which applicant would be in the treatment group and receive a tour that semester and which would be in the control group and have its tour deferred.
We administered surveys to 10,912 students and 489 teachers at 123 different schools three weeks, on average, after the treatment group received its tour. The student surveys included multiple items assessing knowledge about art as well as measures of critical thinking, historical empathy, tolerance, and sustained interest in visiting art museums. Some groups were surveyed as late as eight weeks after the tour, but it was not possible to collect data after longer periods because each control group was guaranteed a tour during the following semester as a reward for its cooperation. There is no indication that the results reported below faded for groups surveyed after longer periods.
We also assessed students’ critical-thinking skills by asking them to write a short essay in response to a painting that they had not previously seen. Finally, we collected a behavioral measure of interest in art consumption by providing all students with a coded coupon good for free family admission to a special exhibit at the museum to see whether the field trip increased the likelihood of students making future visits.
All results reported
All results reported below are derived from regression models that control for student grade level and gender and make comparisons within each matched pair, while taking into account the fact that students in the matched pair of applicant groups are likely to be similar in ways that we are unable to observe. Standard validity tests confirmed that the survey items employed to generate the various scales used as outcomes measured the same underlying constructs.
The intervention we studied is a modest one. Students received a one-hour tour of the museum in which they typically viewed and discussed five paintings. Some students were free to roam the museum following their formal tour, but the entire experience usually involved less than half a day. Instructional materials were sent to teachers who went on a tour, but our survey of teachers suggests that these materials received relatively little attention, on average no more than an hour of total class time. The discussion of each painting during the tour was largely student-directed, with the museum educators facilitating the discourse and providing commentary beyond the names of the work and the artist and a brief description only when students requested it. This format is now the norm in school tours of art museums. The aversion to having museum educators provide information about works of art is motivated in part by progressive education theories and by a conviction among many in museum education that students retain very little factual information from their tours.
