This paper shares research findings that explore the link between conceptual understanding, free exploration of hands-on science center exhibits, and Piagetian cognitive developmental levels. Implications on museum exhibits and field trip experiences are examined as well.
The Children's Museum proposes to develop two versions of an interative physical.science exhibit dealing with wave mechanics and the related actions of vibrating and oscillation systems. One version will be a permanent exhibit that is to be a central component in the new science area of the museum, while the other will be a traveling exhibit that will tour the country under the auspices of the Association of Science.Technology Centers. The purpose of the exhibit is to heighten the interest of children in scientific experimentation, with learning taking place at three levels including sensory.motor, perceptual.operational and intutitive.conceptual. Materials for teachers will supplement the exhibit, and an internship program will train largely minority middle.school students in basic concepts and then use them as "explainers" for the general public. The request to the National Science Foundation represents 73% of the total cost of the exhibits, with the remainder coming from institutional and other sources.
Children's Television Workshop is embaring on a ground- breaking experiment in informal science education: the production of an entertaining animated series of 13 half- hour programs for Saturday morning commercial television, based on David Macaulay's bestselling book, The Way Things Work. The audience will be six- to eleven-year olds, with special focus on minority and economically disadvantaged children. The series' primary goal will be to entertain children with lively and appealing characters in a dramatic storyline, while stimulating children's interest in the scientific principles behind the workings of familiar machines and illustrating the action of their parts. NSF support will enable CTW to adapt the CTW Model -- the collaborative process used in earlier NSF-supported programs, 3-2-1 Contact and Square One Tv -- to the opportunities of the animation format and the realities of the partnership with a commercial network. Through a development agreement with CBS, CTW has begun the process of developing the series concept, characters, and storylines. Upon successful completion of this phase, production will follow with an anticipated broadcast premiere in fall 1992. NSF's $2.36 million support will allow this project to be possible by completing the series' funding; it will allow CTW to conduct significant formative research and summative analyses of educational impact, and to reach large minority and economically disadvantaged audiences through wider promotion and the creation and distribution of complementary print materials.
To provide the general public with an understanding of the basic principles that underlie the transmission, storage, and retrieval of information, the Fleet Center proposes to build SIGNALS, a 4,500 square foot exhibition. SIGNALS will be divided into three sections, of approximately 15 interactive exhibits each, which explore the physical principles of wave motion, the properties of electromagnetic pulses useful for communications, and the signal processing that enables us to handle information. An Advisory Committee comprised of highly qualified individuals at the leading edge of their fields will support development of SIGNALS; a very experienced team of exhibit developers will fabricate the exhibition. SIGNALS will become a permanent exhibition in an expanded Fleet Center, where it is expected to attract 1 million visitors a year, including at least 100,000 K-12 students. Since the lack of technological understanding is a national problem, we propose to build a 3,000 square foot traveling version of SIGNALS, contingent upon an NSF review of the completed permanent exhibition. The total cost for both exhibitions is $1,983,480. We are requesting $985,900 from NSF: $692,800 for the permanent exhibition and $293,100 for the traveling exhibition. The project will begin in June, 1992, and be completed by June, 1996.
The Science Museum of Minnesota will develop a series of "experiment benches" that are to be an unique feature of "labworks," a major new hall of physical science and technology. The small bench-top laboratory exhibits will allow visitors to create their own experiments and to become informally but directly involved in the experimental process. The target audience is junior highschool students, especially those who come as individuals and who are repeat visitors. Selected students will be trained as interns and will be paid to act as mentors for visitors. The project will include a published report, "a recipe book" for dissemination, and a subsequent conference of exhibit developers from other science museums.
The Thames Science Center collaborative with the resources of the Smithsonian Astrophysical Observatory, Wesleyan University and the National Air and Space Museum will design and develop the project, "Shoot For the Moon." This science education project will capitalize on the attraction, familiarity and proximity of the moon using it as a basis to enrich and supplement the eight and ninth grade physical science curriculum. Ten classroom units, complimentary experiments and demonstrations will be developed. "Moonwatch" software and audio visual materials, including an instructional videotape and a multi.image presentation will accompany the units. Sixteen teachers and museum educators will participate in the training, evaluation and testing as the project is integratedinto the curriculum of twelve schools and four museums. The project is designed to be replicated in schools and science centers in different geographical locations nationally. The site for development and testing will be the Thames Science Center, a regional science museum in eastern Connecticut. The science center offers formal science enrichment programs and tours for students and teacher professional development programs throughout the region.
