"Practices and programs of museums are changing and are vastly different from those of past museums. New approaches to the museum experience include visitor's participation in activities, hands-on experiences, and conducting civic and performing-arts functions in the museum. These are just a few of the emerging trends which give the museum a more dynamic role in education and recreation. Many new museums are more public than ever before - - places where people gather and participate in a variety of cultural experiences. The changes in roles and experiences manifest themselves in the form of the museum. This presentation will demonstrate the links between activities and physical form at different levels and scales: from the "interactive core," which responds to new concepts of display at the micro scale, to "common grounds" which provide a place for large gatherings and often make connections to the surrounding urban environment."
