Temple University's Institute on Aging (Philadelphia, Pennsylvania) has developed a unique model for cross-age learning. During the summers of 1980 and 1981, two intergenerational learning retreats were held which (1) provided participants with an innovative educational and cultural experience; (2) fostered communication among persons at different life stages; (3) broke down age-related myths and stereotypes; and (4) served as a demonstration project for other local and national intergenerational activities. The 50 to 60 persons involved in each retreat were diversified in terms of age (ages 14-93), race, ethnic background, socioeconomic status, and education. The week-long retreats, planned by intergenerational advisory committees, provided stimulating educational programs and activities which would stimulate interaction among the different age groups. The programs were divided into three distinct but integrated components: academic sessions, core groups, and recreational/cultural activities. All age groups reacted positively to being closely involved with people of different ages. A factor contributing to the success of the retreats was the collaborative learning/teaching relationship which was promoted. It was hoped that the retreats would be catalysts for other intergenerational activities and, to further this goal, a number of followup actions were initiated. (EM)
