Creativity in education research has received increasing attention, although the major focus of this research has been on children. Despite pleas by several adult educators for promoting creativity, very few studies have focused on adult learners, leaving to it to be explored what approaches are useful for adult educators to facilitate creativity in adult learners and how to construct those approaches. Therefore, this study aimed at examining whether developing creativity is also an important element in adult education, through studying the effects of brainstorming and play activities on adults' creativity. Creativity research suggests that (a) everyone possesses creativity and (b) creativity can be taught and developed. Therefore, teachers are an important resource in facilitating students' learning experience and unleashing their potential in the classroom. The purpose of this study was to examine the effects of brainstorming and play activities on adults' creativity. A quasi-experimental, 2 x 2 factorial study with a convenience sampling was used for the current study. Forty-six adults were recruited from four classes in a Southwestern U.S. private university. The four classes were randomly assigned to one of four conditions (two treatments: brainstorming and play), with three being experimental groups and one a control group. Each treatment was allowed ten minutes for completion. After experiencing different treatments, participants took 20 minutes to create a collage as a product to reflect their creativity. The 46 collages were evaluated by six experts in terms of three dimensions: creativity, technical goodness, and aesthetics. The assessment procedure followed the guidelines of the Consensual Assessment Technique. The major findings indicated that although play and brainstorming did not show an effect in this research, there was a nonsignificant trend showing subtle gender effects. Interpretation of results should be treated with caution because of several identified limitations. Possible directions for future studies and a model for artistic creative performance were also proposed. [The dissertation citations contained here are published with the permission of ProQuest LLC.
