This research examines some of the factors that influence the learning process in an informal science education setting such as the Explora Science Center. Goals of the study include the completion of a qualitative as well as quantitative study on adult learning in an informal, hands on setting, observing and determining the learner characteristics which are crucial to the learning experience, and determining the multicultural use factors in a culturally diverse community. Statistical information on who visits which exhibits for what period of time is included. Age and gender are represented in the data displays and findings indicate that there are age and ethnic effects in adult visitor interaction with the exhibits. Numerous data tables are included to lend additional support to the research project. (Contains 29 references.) (DDR)
