This project develops an 8-week middle-school mathematics module that introduces cryptography, the science of sending secret messages, while teaching and reinforcing the learning of related mathematical concepts. The topics range from the classical encryption systems and the historic context in which they were used through powerful modern encryption systems that provide secrecy in electronic messages today. The module also covers passwords and codes that correct errors in the transmission of information. Public awareness of the importance of cryptography is growing, as is the need to understand the issues involved. The study of cryptography provides an interesting context for students to apply traditional mathematical skills and concepts. Mathematical topics covered include percents, probability, functions, prime numbers, decimals, inverses and modular arithmetic. The main product is a middle-school student book, with accompanying teacher materials. A web site is being developed that supports the activities in this book. Abbreviated modules for Grades 3, 4 and 5 are also being developed, as well as an instructor's guide for adapting the materials for use in informal educational settings such as museums and after-school programs. The development of the module involves piloting and field-testing by experienced classroom teachers from diverse school communities and instructors of informal educational programs. Evaluation includes review by mathematicians and educators, as well as an investigation into the level of students' understanding of the topics studied.
The "Crafting & Evaluating Interactive Educational Websites" conference will be developed through a collaboration between the Cornell University Laboratory of Ornithology and the Exploratorium. The PIs will develop and host a three-day invitational conference focusing on the practice of interactive web site design, development, evaluation and maintenance intended to achieve or support informal STEM learning. The conference, which will be held in Spring, 2005, will involve 50 individuals with a wide range of expertise who will focus on a variety of issues including audience expectations and abilities, designing for learner outcomes, testing for usability, evaluation tools and accessibility. With regard to intellectual merit, conference attendees will explore challenges and barriers that hinder development of truly interactive web sites and identify best practices and promising models, tools and technologies for encouraging authentic public interaction. Conversations begun at the conference will be extended to a broader audience through development of an online manual, informed by the conference presentations and commentaries, and designed for use by the museum, media and research communities. An interactive Web site developed after the conference will allow Web developers to locate content and ideas for design, and to share new ideas and results of usability studies and evaluations.

This comprehensive ITEST project would provide sixty middle and high school teachers with an introduction to Geographic Information System (GIS) and Global Positioning System (GPS) technologies. The project, which brings together a leadership team of educators, science researchers and experts in resource management, is based at the University of Maryland Center for Environmental Science Appalachian Laboratory, a research facility that studies stream and forest ecosystems. The program will focus on environmental applications in which teachers use probes to investigate the properties of local forest and stream ecosystems. Teachers will apply their technology experiences to creating standards based lessons aligned with local curricula. The teacher participants will be recruited from rural, underserved Appalachian communities in western Maryland and northern West Virginia. Local students will be recruited to participate in a four-day summer session that includes field-testing the proposed lessons and learning about career opportunities in information technology.
This project continues the development, testing, and use of a series of web-based computer simulations for improving the teaching and learning of physics. It expands the number of simulations in physics, creates new simulations addressing introductory chemistry, creates simulations addressing the conceptual understanding of equations in solving science problems, and further refines some existing simulations. It increases, by approximately 35, the 35 online interactive simulations that have been developed for teaching physics. The project produces and widely disseminates on-line supporting materials for use in undergraduate and high school science courses. The supporting materials include: guided-discovery, tutorial worksheets; a list of learning goals; materials to support in-lecture, homework, and laboratory use; assessment instruments; and other user-contributed materials. The simulations being introduced and their effectiveness are being evaluated in at least eight additional courses in physics and chemistry at the University of Colorado and a diverse set of partner institutions. The materials are being extensively tested to ensure that they are easy to use and effective at promoting deep conceptual understanding and positive attitudes about science and technology.

Media Arts within primary and secondary education is a relatively new avenue of research. Within the context of the arts classroom, rarely is learning to program emphasized despite its importance for creative expression in a digital medium. We present outcomes from an extensive field study at a digital studio where youth accessed programming environments emphasizing graphic, music and video. Learning the language of creative coding is essential to expression in a digital medium — one with increasing importance for youth and society at large. Here, we argue that it’s not just in the viewing or
This paper presents ten guiding principles for designing construction kits for kids: design for designers; low floors and wide walls; make powerful ideas salient - not forced; support many paths, many styles; make it as simple as possible - and maybe even simpler; choose black boxes carefully; a little bit of programming goes a long way; give people what they want - not what they ask for; invent things that you would want to use yourself; and iterate, iterate - then iterate again.
