This research identified and compared the learning styles of 154 ethnically diverse, upper division undergraduate and graduate students in Allied Health utilizing the "Building Excellence" (BE) (Rundle & Dunn, 2000) and the "Productivity Environmental Preference Survey" (PEPS) (Dunn, Dunn, & Price, 1996). Relationships among age, class standing, ethnicity, gender, and learning style also were examined. Correlation analyses indicated relationships between students' learning-style elements (p less than 0.001), with large effect sizes for Sound, Light, Temperature, Seating Design, Intake, Time-of-day and Mobility, Auditory, Tactile, and Kinesthetic preferences. Gender related learning-style characteristics revealed female preferences for learning by listening and male preferences for cooler temperatures, frequent movement, and learning in a pair or team during instruction. Analyses of variance and follow-up post hoc tests revealed significant age-related learning-style differences for Structure, Intake, Mobility, Early-Morning and Afternoon, and Auditory preferences.
