The St. Louis Science Center is a major metropolitan science museum serving a population of 2.3 million people. One year ago they moved into a new facility at a new location and attendance at the museum has tripled, reaching 600,00 visitors this past year. The center will develop a "Science Playground" in order to teach basic science principles and process through a series of 45 outdoor participatory exhibitions around the major areas of motion, energy, light, sound and the natural environment. The physics of motion will be explored through exhibits such as a friction slide, lunar gravity swing, double-axis human pendulum, etc. Energy exhibits will provide experiences with watermills and water power, fulcrum leverage and solar energy. Light exploration includes a solar column, prisms and rainbows, soundwheel and whisper discs. A weather station will have a rain gauge, anemometer, a variety of barometers, etc. This contemporary playground concept was developed as a response to limitations of indoor facilities and to extend use of outdoor space in a creative manner. The exhibit will be a model for extending science learning opportunities for schools, parks, other science museums and similar institutions. The center surveyed 31 science centers, 82 parks and 85 school districts to gauge interest in use of science playground exhibits, and found a clear interest in this type of project by all sectors surveyed. Exhibit designs will be published and furnished at cost to any facility wishing to replicate all or any part of the exhibition.
The investigation of naive conceptions of science has many implications for both teaching and learning. The predominant model for past investigations has been with school children or within very formal settings. Extending investigations of misconceptions to informal settings is the challenge of this research. Museum visitors' misconceptions about two topics, gravity and mechanical advantage, will be recorded through a variety of interview formats. Twenty-five persons from each of the age ranges 9-11, 12-14, 15-18, and college students/adults will be interviewed. Information from the interview will be used to modify the current exhibit or to build new prototypes. The research will determine if a modification can be made that results in individuals moving from their previous misconceptions toward a correct conceptualization of the concepts. This research will document what individuals actually learn from museum exhibits and how "front end evaluation" can be used to redesign exhibits for maximum concept learning. The proposed research is challenging and has the potential of adding significant information to science education research on misconceptions. The principal investigator is highly respected in the field of museum education and the associated staff and consultants are the top scholars in their respective fields.
