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.
"3-2-1 Contact," the nationally broadcast award winning children's public television science series, has been reaching children aged 8-12 with daily half hour science programming since 1980 with support from both the National Science Foundation and the U. S. Department of Education. In seven seasons of production, CTW has produced 225 regular and two special shows, generating an estimated 633 million viewings by the target audience and more than 1.66 billion viewings by viewers of all ages. With completion of primary show production, the series will begin repeat broadcasts in the fall of 1989 drawn from the library of existing programs. This final award will support continued broadcast of the series and insure the widest possible distribution and utilization of "3-2-1 Contact." CTW will implement a Transition Plan to sustain series broadcast, establish series access as a VCR based science resource, and insure permanent access for teachers, schools, and out of school resources to the "3-2-1 Contact" program library. Broadcast activities will include supporting a portion of the costs of residuals for rebroadcast for a five year period, production of five "3-2-1 Contact EXTRAS" -- single topic half hour specials with high visibility -- and encouraging increased off air taping of the series by teachers. Support for school use of the series will be strengthened with the development and distribution of topic indexing software and teacher guides, the creation of short "3-2-1 Contact" segments specifically tailored to the classroom needs of teachers and a series blockfeed to schools to create a permanent archive of shows. Community outreach partnerships will be strengthened and home video opportunities explored as well. This five year award will allow millions of American children the continued opportunity to view science programming after school on a regular basis, and will assist their teachers in making effective use of "3-2-1 Contact" program materials in classroom settings.

This exploratory study is designed to determine attributes of large urban school districts which would maximize the probability of success for implementing and sustaining major educational reforms. The study will include personal interviews with key change agents in a number of such school districts where changes have been attempted and will identify attributes which lead to failure as well as those which lead to success. The project will culminate with a draft document of an "Urban School District Systemic Reform Initiative in Science and Mathematics" which incorporates findings, in NSF solicitation format.
The Museum of Northern Arizona proposes to initiate a two-part project in natural-science education on the Colorado Plateau, with a strong focus on the Native Americans of the region, and especially their children. The project involves, one, the installation of modern geology and biology exhibits that are highly relevant for understanding the natural history of an important area and, two, the development of two closely associated new educational outreach programs, one based on well designed kits for school use and the other involving the training of teachers in the use of those kits.
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.
The New York Hall of Science, working with the Association of Science-Technology Centers Traveling Exhibition Service proposes to develop, test and nationally tour a 500 square foot hands-on exhibition and associated education materials for use by students, teachers, and families on AIDS and the human immune system. The program will be targeted at grades 6 - 12 and their families. It will be developed in year one and then toured in years two and three. One copy of the exhibition will be presented at the New York Hall of Science for the highly AIDS impacted metropolitan area. The other copy of the exhibition will tour to 10 museums nationally. Annual training for the touring sites will ensure that the exhibition and materials can be effectively utilized in conjunction with existing education and science career programs in each city. It is stated that the exhibition and education materials will improve the public understanding of contemporary science and medicine by communicating one essential component of twentieth century biology seldom presented to the public: the fundamentals of microbiology underlying the much-discussed AIDS epidemic. Learning objectives designed for age appropriateness include: (1) to understand the nature of HIV and the difference between testing positive for HIV antibodies and having AIDS; (2) to understand the operation of healthy and infected immune systems; (3) to understand what behaviors result in the spread of HIV and (4) to understand how people can prevent infection. In order to ensure effectiveness in meeting these goals, an independent evaluator will be employed in year one to evaluate each stage of the exhibition in formation and, then, in year two to produce summative evaluation for dissemination to the health and museum education fields.
