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.
The Franklin Institute Science Museum will design, test, fabricate, and circulate to eight museums an exhibit, "The Science of Music: Sound Waves and Sound Forms" that will introduce visitors to the physical laws that govern sound waves. By using music as an attractive and concrete subject to engage broad public interest, the exhibit will illustrate such topics as sound wave amplitude, phase, frequency, reflection and interference. Primary support for the project comes from the eight member Science Museum Exhibit Collaborative, consisting of: the Franklin Institute Science Museum, Philadelphia, PA; Discovery Place, Charlotte, NC; the Fort Worth Museum of Science and History, Fort Worth, TX; the California Museum of Science and Industry, Los Angeles, CA; the Science Museum of Minnesota, St. Paul, MN; the Museum of Science and Industry, Chicago, IL; the Center of Science and Industry (COSI), Columbus, OH; and the Museum of Science, Boston, MA. Each has contributed $50,000 and the costs of exhibit shipping and maintenance. Direct matching fund support totals more than $381,000. The exhibit will spend three months in each location, and the total audience will exceed 1.5-million visitors over its eight museum tour. This project will extend the work of a group of museums that are already helping each other in a collaborative effort. The exhibit concept has high public appeal among groups that science finds it hard to reach, including teenagers and minorities. An FY87 award of $145,000 is recommended.
