This model science teacher retention and mentoring project will involve more than 300 elementary teachers in "Lesson Study" of inquiry science around school gardens. Drawing on the rich resources of the University of California Botanical Garden and the science educators at the Lawrence Hall of Science this project will develop Teacher Leaders and provide science content professional development to colleagues in four urban school districts. Using the rich and authentic contexts of gardens to engage students and teachers in scientific inquiry opens the opportunity to invite parents to become actively involved with their children in the learning process. As teachers improve their classroom practices of teaching science through inquiry with the help of school-based mentoring they are able to connect the teaching of science to mathematics and literacy and will be able to apply the lesson study approach in their teaching of other innovative projects. Teacher leaders and mentors will have on-going learning opportunities as well as engage participating teachers in lesson study and reflection aimed toward improving science content understanding and the quality of science learning in summer garden learning experiences and having context rich science inquiry experiences throughout the school year.
This collaborative project aims to establish a national computational resource to move the research community much closer to the realization of the goal of the Tree of Life initiative, namely, to reconstruct the evolutionary history of all organisms. This goal is the computational Grand Challenge of evolutionary biology. Current methods are limited to problems several orders of magnitude smaller, and they fail to provide sufficient accuracy at the high end of their range. The planned resource will be designed as an incubator to promote the development of new ideas for this enormously challenging computational task; it will create a forum for experimentalists, computational biologists, and computer scientists to share data, compare methods, and analyze results, thereby speeding up tool development while also sustaining current biological research projects. The resource will be composed of a large computational platform, a collection of interoperable high-performance software for phylogenetic analysis, and a large database of datasets, both real and simulated, and their analyses; it will be accessible through any Web browser by developers, researchers, and educators. The software, freely available in source form, will be usable on scales varying from laptops to high-performance, Grid-enabled, compute engines such as this project's platform, and will be packaged to be compatible with current popular tools. In order to build this resource, this collaborative project will support research programs in phyloinformatics (databases to store multilevel data with detailed annotations and to support complex, tree-oriented queries), in optimization algorithms, Bayesian inference, and symbolic manipulation for phylogeny reconstruction, and in simulation of branching evolution at the genomic level, all within the context of a virtual collaborative center. Biology, and phylogeny in particular, have been almost completely redefined by modern information technology, both in terms of data acquisition and in terms of analysis. Phylogeneticists have formulated specific models and questions that can now be addressed using recent advances in database technology and optimization algorithms. The time is thus exactly right for a close collaboration of biologists and computer scientists to address the IT issues in phylogenetics, many of which call for novel approaches, due to a combination of combinatorial difficulty and overall scale. The project research team includes computer scientists working in databases, algorithm design, algorithm engineering, and high-performance computing, evolutionary biologists and systematists, bioinformaticians, and biostatisticians, with a history of successful collaboration and a record of fundamental contributions, to provide the required breadth and depth. This project will bring together researchers from many areas and foster new types of collaborations and new styles of research in computational biology; moreover, the interaction of algorithms, databases, modeling, and biology will give new impetus and new directions in each area. It will help create the computational infrastructure that the research community will use over the next decades, as more whole genomes are sequenced and enough data are collected to attempt the inference of the Tree of Life. The project will help evolutionary biologists understand the mechanisms of evolution, the relationships among evolution, structure, and function of biomolecules, and a host of other research problems in biology, eventually leading to major progress in ecology, pharmaceutics, forensics, and security. The project will publicize evolution, genomics, and bioinformatics through informal education programs at museum partners of the collaborating institutions. It also will motivate high-school students and college undergraduates to pursue careers in bioinformatics. The project provides an extraordinary opportunity to train students, both undergraduate and graduate, as well as postdoctoral researchers, in one of the most exciting interdisciplinary areas in science. The collaborating institutions serve a large number of underrepresented groups and are committed to increasing their participation in research.

Flip It, Fold It, Figure It Out! is a 1500-sq. foot traveling mathematics exhibition with companion take-home educational materials. There are two copies of the traveling exhibit: one for the members of the North Carolina Grassroots Science Museums Collaborative reaching over 500,000 visitors, and a second for travel nationally to science centers reaching an estimated 750,000 additional visitors. Take-home activity kits were developed for visitors to continue informal mathematics explorations at home. The activities included expand and extend the exhibit themes, offering multiple levels to meet the needs of K-5 students and their families.
The Developmental Studies Center (DSC) will implement "Home, School and Community: AfterSchool Math for Grades 3-5," a program that targets at-risk and low income children in afterschool programs. AfterSchool Math trains youth workers to help students in grades 3-5 better understand measurement and geometry concepts, building on the success of the NSF-funded Home, School and Community mathematics program for grades K-2 (ESI #97-05421). The project develops, field-tests and evaluates thirty math games and ten story guides, which support the social and mathematical development of children, while emphasizing cooperative learning. The content for all materials will be aligned with national standards in mathematics. A 12-hour professional development workshop for youth workers and an 18-hour workshop for facilitators or youth worker leaders are also planned. Two training videos and a facilitator manual will be produced to support this aspect of the project. Field testing will occur in Kansas, Louisiana and Missouri. This proposal has been augmented to include a special emphasis on rural communities which doubles the number of field test sites from 50 to 100. A Rural Outreach Specialist will conduct focus group meetings to determine needs unique to rural programs and lead the field testing in these communities. It is anticipated that over 3,200 youth workers will be trained and a national cadre of more than 300 youth worker leaders will be created.
