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 middle-school and high-school years are a period of change and crystalization in terms of life goals, disciplinary and course preferences, and social and political attitudes. The literature provides a number of cross-sectional descriptions and models concerning cognitive and attitudinal development during adolescence and young adulthood, but there are no longitudinal data available to study these processes. The proposed longitudinal study will examine the (1) development of interest in science and mathematics, (2) the growth of scientific literacy, (3) the development of attentiveness to science and technology issues, and (4) the attraction to careers in science and engineering among two national cohorts of adolescents and young adults. One cohort will begin with a national sample of 3,000 seventh graders and follow them through the 10th grade. The second cohort will begin with a national sample of 3,000 10th graders and follow them for the next four years through the first full year after high school. Data will be collected from students, teachers, counselors, principals, and parents. A purposive sample of two or three school districts with exemplary elementary school science and mathematics education programs will be selected and comparable data will be collected in these districts. The analysis will consist of a series of expanding multivariate developmental models that will seek to understand cognitive and attitudinal growth and change in the context of family, school, and peer influences. Each wave of data collection will provide an opportunity to examine cognitive and attitudinal change measures in an increasingly rich context of previous measures. Periodic reports will be issued with each cycle of data collection and the data will be made available to other scholars on a timely basis. The first phase of the project, being funded at this time, provides approximately 15 months for instrument development and pilot testing, for sample selection, for monitor selection and training, and for working with the research advisory committee.
