He says, "We found a strong causal relationship between arts-based learning and improved creativity skills and innovation outcomes in adolescents, and between arts-based learning and increased collaborative behavior in adults."
• The high school students who had arts-based learning showed large and statistically significant pre/post improvements in such creative thinking skills as idea range (13%), problem analysis (50%) and number of solutions generated (37%). In many cases, students who had traditional STEM learning actually declined in these aspects of creative thinking -- so the overall differentials between arts-based and traditional learning was even more dramatic (idea range = 22%, problem analysis = 121%, solutions generated = 43%). Thus, it appears as though arts-based learning may be an effective way to "inoculate" learners against the collapse of creativity that may sometimes accompany traditional forms of high school learning.
• Arts-based learning had a far more powerful impact on the collaborative behaviors of adults than traditional learning, based on actual observed behaviors. Examples from the final week of the study: arts-based teams exhibited 56% more instances of empathic listening, 33% more instances of mutual respect being shown, 119% more instances of trust being demonstrated and 24% more sharing of leadership. All differences cited here are statistically significant.
• The innovation outputs of high school student teams who had arts-based learning showed 111% greater insight into the challenge, a 74% greater ability to clearly identify a relevant problem, a 43% improvement in problem solving, and their innovations had 68% more impact. All are statistically significant.
• 120 days after the study, high school students who had arts-based learning were 24% more likely to have been able to apply the learning to school, extracurricular, work or volunteer activities, than students who had traditional learning. They were also 44% more optimistic in their belief that the training would prove helpful in those realms in the future.
