Mixed-methods research focused on identifying guest behavior was conducted at four focal exhibits at MOXI, the Wolf Museum of Exploration + Innovation in southern California. Teams researching two exhibits, Turn Tables and Keva Planks, were additionally interested in assessing whether modifications or manipulations to the physical exhibit impacted guest stay time. The team examining Turn Tables, a set of rotating tables, found that adding a graphic to the exhibit had a significant impact on engagement with increasing complexity (p < .05). Researchers investigating Keva Planks, which are small wooden planks guests can use to make structures, assessed how the presence of a museum floor facilitator or existing structures at the exhibit influenced stay time and engagement, and found a statistically significant difference in mean stay time in the case of both facilitator and structure present compared with only a structure present (p < .05). The final two studies used mainly qualitative observations to identify guest behaviors when interacting with exhibits. The team studying Magnetic Islands, a small magnetic structure guests can attach washers to, documented three engagement types: basic playing, building structures, and exploring magnetism. Findings indicate that when children engaged with peers rather than visiting the exhibit alone, they exhibited more complex engagement types. The final study focused specifically on the behaviors of young children to characterize the ways they chose to engage with the Light Patterns exhibit, a large color peg board covering an entire will. Findings suggest children exhibited many different behaviors at Light Patterns that demonstrated evidence of engagement with STEM practices. This research contributes to topics about Research Practitioner Partnership (RPP) models, mixed-methods research, museum facilitation, learning affordances in museum spaces, and the impact of exhibit design on the museum guest experience.
