Progress in understanding cognitive developmental change mechanisms requires methods that yield detailed data about particular changes. The microgenetic method is an approach that can yield such data. It involves (a) observations of individual children throughout the period of the change, (b) a high density of observations relative to the rate of change within that period, and (c) intensive trial-by-trial analyses intended to infer the processes that gave rise to the change. This approach can illuminate both qualitative and quantitative aspects of change, indicate the conditions under which
This article outlines an experiment in which sixty-four sixth-grade students were divided into two groups: a control group, which was given novelty-reducing treatment on a field trip, and a placebo group, which was not subject to novelty-reducing treatment. Results of the experiment showed that exploratory behavior was positively correlated with cognitive learning.

The Buffalo Society of Natural Sciences plans to conduct a 5 year project to train 150 mentor teachers (30 teachers/year) and their principals, who will then train the remaining 1100 elementary teachers in the Buffalo Public School System. The training would include two 5-week summer sessions (in a Magnet school that is physically incorporated into the Buffalo Museum of Science) and 4 in-service workshops during the academic years following each of the summer workshops. This innovative leadership project is a collaborative effort between the Buffalo Society of Natural Sciences (including both education and curatorial/science staff persons) the Buffalo Public Schools, and individuals from local colleges and universities. The setting of the project is enhanced by a Science and Math Magnet School which is housed within the museum, and by the school/museum's location in a largely inner city environment with easy accessibility to minority persons. The project is designed to provide mentor teachers with a strong science background in pedagogy and content over a two-year period of summer and academic-year workshops, and to prepare and support these mentors as they inservice their colleagues. Project staff from the museum, public schools, and the academic community will provide strong support through academic-year workshops, site visits and telecommunications networking. Principals will be appropriately involved, and will work with mentors to develop a science inservice program tailored to meet the needs of their individual schools; as a consequence, virtually all of the 1100 K-6 classroom teachers of science in the Buffalo Public Schools will have been prepared to teach investigative, hands-on science to their students. Non-NSF cost sharing is approximately 27.9% of the amount requested from NSF.

Chemistry in the Community (ChemCom) was designed to provide an attractive, open access route for all high school students to the realm of relevant and useful chemical phenomena. What began as a dream a few years ago is now a well-developed high school program brought about by the concerted efforts of high school teachers, college and university professors, and industrial chemists and financed by the National Science Foundation and the American Chemical Society. This three-year project is designed as a partnership to support the dissemination of the Chemcom curriculum. Specially selected teachers will be educated so that they can become resource teachers who will conduct ChemCom inservice workshops throughout the country. These resource teachers are expected to represent as many as 150 school systems and will reach as many as 2,000 teachers with their inservice programs. The project also includes a series of networking activities entitled "An Evening with ChemCom, the establishment of a computer network, and the production of a newsletter. The evaluation will focus on the effectiveness of this particular model for implementing curriculum change. The total cost sharing (ACS, Publisher, School Systems) is expected to be almost five times the NSF request.

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 Lawrence Hall of Science proposes to develop a major public education program, including a traveling exhibition, two planetarium programs, a play, and a kit for schools entitled "Columbus' Great Experiment." Emphasizing science and technology, Columbus' first voyage is portrayed as an experiment aimed at testing the hypothesis (based on doubtful evidence) that sailing to the west was a more practical way of reaching the Indies than by sailing east around the Horn of Africa. As with many scientific experiments, the results were quite different from what the experimenter had in mind: instead of finding a sea route to the Indies, Columbus vastly expanded knowledge about our planet and spurred developments in science and technology. These events occurred within a social and cultural context that were critical to the development of modern science, and resulted in far-reaching changes in the population and ecology of the world which continue today. The National Endowment for the Humanities has recently awarded a grant for the development of the exhibits. The present proposal requests that NSF join with NEH to complete and expand the project, by funding: a) components of three additional copies of the exhibition to be constructed by other museums, thus expanding the public audience to 19 million visitors; b) two participatory planetarium programs; c) a play about the scientific aspects of Columbus' voyage; and d) school kits that will enable teachers to present the most important ideas embodied in the exhibition to students who are unable to view the exhibition at a science center. Interest in these programs will peak around Columbus Day, 1992, we anticipate that the materials will be sufficiently interesting, informative, and entertaining to be used for many years to come.
Scientists and engineers are an underutilized resource in motivating students and assisting classroom teachers in teaching science. Pilot programs have demonstrated the value of preparing scientists for what to expect when they enter the classroom, how to incorporate the school curriculum into their program, and how best to reach the goal of making their visits a "never to be forgotten" life changing experience for students. The concept of a Survival Kit is an outgrowth of a Scientist-in-Residence program at the North Carolina Museum of Life and Science which has successfully matched scientists and public school classrooms locally since 1982. The North Carolina Museum of Life and Science proposes to conduct meetings for staff and outside educational specialists to identify the materials and strategies needed to prepare scientists to enter school classrooms. The final report of these meetings will include mechanicals of a Scientist Survival Kit, which can be disseminated across the country, and an evaluation report of how the kits can be and are used. Dr. Mark St. John, Inverness Associates, a professional evaluator noted for his work with nationally significant science education projects, will provide local and national evaluation through surveys and meetings to give a picture of the issues involved in establishing and maintaining programs of scientists in the schools and the role played by the Scientist's Survival Kit in furthering this aim.

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 middle school years are critical in determining a student's success and continued participation in mathematics. This proposal involves the expansion of MESA (Mathematics, Engineering, Science Achievement) model to the junior high/middle school population in the State of Washington. The project will focus on updating and revitalizing middle school mathematics curriculum, the goal being to increase minority student enrollment in algebra in the ninth grade. The MESA model also recognizes the need for teacher support and provides teacher seminars on a regular basis. Additionally, the expansion of the statewide Pre- College Center at the University of Washington will include the coordination of a statewide program at the junior high/middle school level. The MESA model is based on a partnership between industry and educators--a cooperative effort involving scientists on loan from industry, educators at the university level and educators at the secondary school levels working together to develop curricula that will stimulate student interest and achievement in mathematics and science. The staff for the project is well qualified with experience in the MESA program and in curriculum development and teacher training. The proposal addresses a clear need for improving minority mathematics education in middle/junior high schools and promises to have an impact throughout the nation for all students by serving as a model academic program. The project goals are consistent with the Instructional Materials guidelines. Therefore, an award is recommended.
The Mississippi Museum of Natural Science proposes to build on its program of activities that involve children in science and bring them into contact with the approaches, objects and equipment that scientists use, with each activity designed to stimulate thinking and heighten interest in science. Cardinal features of the program are the development of hands-on exhibits, science kits for classroom use and a studied tie with the children's television program, "3-2-1 Contact." The goals are to coordinate these activities with hands-on science activities for students in grades 3-6, and to coordinate classroom activities with those at the museum, which conducts "3-2-1 Contact Days" throughout the year when students come to the museum and take part in experiments, observations and enrichment lessons and actively manipulate museum objects. The museum now will refine the program components, including improvement and duplication of the hands-on kits, continuation of the workshops for elementary teachers and development of new participatory exhibits dealing with insects and endangered species, and will present them to an expanded audience. One-third of the children in the state live below the poverty level, and fifty per cent represent minority populations. As most of these children lack such out-of-school experiences these informal science activities are particularly meaningful.
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.
Cognitive research indicates that science experts commonly use diagrams as mediational tools for reasoning visually. But in science education materials and practices, visuals are typically "aids" rather than fundamental representations. This research will examine how students learn to comprehend, use, and construct diagrams as thinking tools. It will focus on the diagram-dense field of beginning optics. The project has two interacting phases: research on how students understand static optics diagrams, and development and refinement of prototype computer- based dynamic diagrams and diagramming tools. Specific tasks are: (1) Pilot research, and analysis of diagrams in optics texts, (2) research on instructional practices with these diagrams, (3) research on student understanding and use of diagrams, (4) design and develop interactive diagrams and a dynamic diagram-construction kit, (5) carry out research with prototypes, and (6) formulate and disseminate implications for creation and use of interactive diagrams in science education. Such research on visual education in science will help guide development of new curricula and software for science education. The project team of cognitive scientists, science educators, graphics specialists, and systems developers is devoted to promoting learning and reasoning in science with new data, theory, and innovative prototypes of dynamic diagrams. These interdisciplinary activities more directly link science education research, materials development, and classroom activities. Cost sharing is provided by the Institute for Research on Learning which is contributing indirect costs and APPEL which is contributing four MacIntosh II systems.
