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 Educational Broadcasting Corporation (WNET in New York) is developing and producing a new public television project exploring cutting-edge technology. The project consists of an eight-part hourly broadcast component; six 60-second "mini-programs;" a World Wide Web component; and extensive educational outreach targeted to adults aged 25-39 and older. The topics for the eight programs in season one are: Replacements - prosthetic devices and biologically electronic artificial body parts In Search of Eve - the race to decode the human genome Light of the 21st Century - Fiber Optics Nanotechnology - molecular manipulation of materials Technospy - technologies used to gain information Sports Technology - the pursuit of better equipment and training regimes Artificial Intelligence - efforts to create computers the mimic human intelligence Appropriate Technologies - technologies that use local, inexpensive material Beth Hoppe, WNET's Director of Science Programs will serve as Executive Producer for the series. Each of the programs would be produced by an independent producer selected by WNET. Content advisors include: Angela Christiano, Departments of Dermatology, Genetics and Development, Columbia University; Sheila Sen Jasanoff, Harvard University JFK School of Government; Horace Freeland Judson, Center for History of Recent Science, George Washington University; Michio Kaku, theoretical physicist, CUNY and host, Explorations radio series; Wilfred Pinfold, Microprocessor Research Labs, Intel Corp.; and Barbara Wilson, chief technologist, NASA's Jet Propulsion Laboratory
