Researchers from the University of Arkansas examined the impact of high-quality theater productions on school groups. This is the first randomized experiment to discover what students get out of seeing live theater. Among students assigned to see live theater, the researchers found enhanced knowledge of the plot and vocabulary in those plays, greater tolerance, and improved ability to read the emotions of others. These results are generally consistent with the researchers’ previous work looking at the impact attending a field trip to an art museum has on students.
