This project is aimed at perfecting and testing a new instructional method to improve the effectiveness of introductory physics teaching. the methods has two chief characteristics: 1) a systematic challenge to common sense misconceptions about the physical world, and 2) an emphasis on models and modeling as basic to physical understanding. Two versions of the method will be tested. The first version is designed especially for high school physics. It emphasizes student development of explicit models to interpret laboratory activities. After an initial test, this version will be taught to high school physics teachers in a summer Teacher Enhancement Workshop, and its effect on their subsequent teaching will be evaluated. Teachers with weak as well as strong backgrounds will be included. A special effort will be made to include females and minorities. The second version will be tested in a special college physics course designed to prepare students with weak backgrounds for a standard calculus based physics course. It emphasizes modeling techniques in problem solving. This project is jointly supported by the Division of Materials development, Research and Informal Science Education and the Division of Teacher Preparation and Enhancement.
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.
This research project is a follow-up to previous research on the persistence of high ability minority youth in college programs for mathematics, science, engineering, premedicine and predentistry. The earlier research used data retrieved from the 1985 College Board files for 5,602 students with SAT mathematical scores of 550 or above. All were minority students except for a comparison sample of 404 White students. In 1987, a first follow-up was conducted. 61 percent of the non-Asian American minority students had enrolled in college and were majoring in MSE fields in comparison with 55 percent of the White students and 70 percent for the Asian American students. In the current phase of this research, the original sample will be resurveyed, five years after high school graduation. A subsample will be interviewed in-depth. The major goal of this phase will be to answer three critical questions: which sample members are still studying or employed in MSE fields, what are their unique characteristics, and what are the theoretical and national policy implications of the results. This project is jointly supported by the Studies and Analysis and the Research in Teaching and Learning Programs.
The Computer Museum proposes to initiate a Computer Exhibits Kits Program whose goal will be to foster a better understanding of computer science and technology among the general public. The program proposes to develop and disseminate nine different kits, each consisting of a computer program, documentation, educational materials and, in some cases, specialized hardware. Other museums and science centers will be able to purchase these well tested kits at modest cost and implement them on personal computers to create exhibits for visitors ten years old and older. Strong support from other institutions suggests that the program will reach twenty million visitors a year.
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.

This project will test an instructional strategy designed to increase the pool of minority students who are successful in their study of algebra and higher mathematics courses. Since 1979, the Comprehensive Math and Science Program at Columbia University has been developing an instructional model designed to give all entering ninth grade students the opportunity to work to their highest level of capacity in mathematics. Key features of the model are a zero-based start, which makes no assumptions on students' prior mathematics background, and a complementary curriculum, which provides a set of parallel, interlocking mathematics courses that substantially increases the rate of mathematics instruction over a four semester period. Preliminary tests of the model in New York City schools have yielded encouraging results. In the current project, the instructional materials will be completed and the model will be extensively tested in New York City and in Fulton County, Georgia. The testing will be accompanied by the development of an apprenticeship model for teacher training, which will pair new teachers with experienced teachers in the interlocking courses of the program.
The 4-H organization of Virginia is developing a Marine and Aquatic Education Program with a strong field study component for youngsters ages five through nine. They plan to reach these young people through local and community 4-H clubs and in summer camps. One part of the program is aimed at the handicapped and development of strategies to meet their special needs. Other components of the program include volunteer training of high school students and adult leaders and a series of publications with emphasis on "hands-on" activities. There is a strong national dissemination plan and, through a national survey, the Virginia 4-H have determined that 27 state 4-H organizations are interested in adapting program. The 4-H organization is the largest youth organization in the United States with a membership of 4.3 million young people. They have a strong network, both urban and rural, with minorities representing 22% of the membership, 53% are female and 63% are under 11 years of age. The Virginia 4-H mirrors the national picture but with a slightly more rural membership. This project provides an opportunity to strengthen science learning outside of the formal education system by supporting a test project in marine education. Over the next three years the project will be tested with 38,500 youngsters and 500 adults. The program will then be expanded to all 115,467 Virginia members as well as a strong outreach effort to the national membership. This project is directed at two important goals for the Informal Science Education Program: strengthening out-of-school science programs for young people and the handicapped. The marine science area is one of high interest and significance both locally and nationally. The staff are experienced and committed and the program is cost effective at a little over $3.00 per person.

The Franklin Institute Science Museum, a major American Science Center serving more than 700,000 individuals annually, proposes to create a 3,700 square foot permanent exhibition that will promote public interest in and understanding of the concepts and principles of mathematics in concrete, tangible form. The exhibition will consist of five clusters of hands-on devices, interactive computer programs, models, and text on the themes of Geometry; Symmetry; Chance, Probability and Randomness; Series, Sequences and Limits; and "Modern Math"--Fractals, Knots and Braids and Topology. Museum staff will utilize several mathematicians as advisors and design participants and will develop adjunct educational materials for use by teachers, students, and family members. They will disseminate exhibition techniques and content by providing six collaborating museums with selected copies of exhibit devices and hardware for their use in developing temporary or permanent mathematics exhibits. Staff of the six museums will join advisors for a design conference during exhibition planning, and will provide evaluation reports on their use of the exhibit materials. Knowledge of mathematics is not only necessary for everyday life; it is central to public understanding of science and engineering, and a key to continued participation in science and engineering, and a key to continued participation in science education in high school and college. Increasing national interest improvement in the mathematical ability of americans at all levels, pre-college and college, make this proposed exhibition particularly timely.
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 Lawrence Hall of Science proposes to develop two 1400 square foot interactive exhibitions based on the latest research findings on the structure and function of the human brain; one for permanent display at the Hall, and one for circulation to 12 science museums over a five year period. The exhibition will use large scale models and equipment from two television programs on the brain. Substantial input from scientists and psychologists will be combined with the educational expertise of curriculum development, museum, and design staff from the Lawrence Hall of Science to create the exhibitions. Visitor and school related curriculum materials will be developed, including a video library and an auditorium show for large group school use. The Lawrence Hall of Science has more than 300,000 visitors per year and is a major science education research and development facility; the twelve host museums will reflect museums in both large and medium sized cities well distributed geographically. More than three million people will view the exhibits over a five year period. The topic is timely, the treatment substantive and educational, and the qualifications of staff and advisors high. The re-use and relationship to a major television series, "The Brain", is an ingenious and effective strategy. The Lawrence Hall of Science is matching the National Science Foundation contribution with comparable private funds. A 24-month FY87 award of $ is recommended.
The Girls Clubs of America (GCA) plans to develop over a three year period informal science learning activities to increase the participation of women aged 14-18 in mathematics and science. These materials are part of an overall program, "Operation SMART," that is a major national commitment by the Girls Clubs of America to include science and mathematics education as a major component of GCA activities at all age levels. Prior projects have developed and implemented successful materials directed at elementary and middle school girls; the present project extends this effort into the critically important high school age years. The materials will be developed by project staff in association with developers at the Educational Development Center (EDC), piloted and tested in four Girls Clubs sites along with training chapters nationwide. A publisher will be identified for national distribution and sales of activity materials sets and a book-length publication designed for use by education programs of other youth-serving organizations. A partnership with the Business and Professional Women's Association (BPW/USA) and its 3400 local chapters and with the AAAS Linkages Project will create many non-Girls Club sites. Dissemination to other youth- serving organizations will be carried out through the National Collaboration for Youth. As a result, Operation SMART's high school age materials should reach several hundred thousand young women. Foundations and businesses will provide substantial additional project support; approximately 51% of the total $ l.4 million project budget is requested from NSF.
The American Museum of Natural History proposes to design and build a new permanent 9,000-square-foot Hall of Human Biology and Evolution over a three-year period. The exhibit is to start out with human biology and then move smoothly to human evolution and the fossil record and other evidences of early humans. The new exhibit will range from the molecular/genetic level to the emergence of human beings, and will include archeological excavations and findings, reconstruction and discussion of humanoids, early human evolution, human structure and function, and human diversity. In addition to stimulating the interests of visitors (2.7 million in 1986-87) in human biology and evolution through the use of traditional and interactive technology, the new exhibit program will provide curriculum supplement for elementary and high school classes and teacher-training guides and workshops to assist in the integration of the exhibition materials into classroom studies. The primary educational goal is to give the widest possible audience a concrete sense of where and how the human animal fits in the natural world through examination of the traits that we share with all creatures and those that are peculiar to humans. The exhibit promises further contribution by bridging the current exhibits on animal life and those on the rich ethnological collections on the diversity of human cultures. NSF dollars are to cover the costs only of planning, building and evaluating the exhibit, with no funds for staff.
