Years before encountering their first formal science lessons in elementary school, children may already be practicing scientific thinking on a weekly, if not daily, basis. In one recent survey, parents reported that their kindergartners engaged, on average, in more than 300 informal science education activities per year - watching science television shows, reading science-oriented books, and visiting museums and zoos (Korpan, Bisanz, Bisanz, Boehme, & Lynch, 1997). This strikes us as a lot, but it is likely to pale in comparison to what young children may experience five years from now
College students (in Experiment 1) and 7th-grade students (in Experiment 2) learned how to design the roots, stem, and leaves of plants to survive in 8 different environments through a computer-based multimedia lesson. They learned by interacting with an animated pedagogical agent who spoke to them (Group PA) or received identical graphics and explanations as on-screen text without a pedagogical agent (Group No PA). Group PA outperformed Group No PA on transfer tests and interest ratings but not on retention tests. To investigate further the basis for this personal agent effect, we varied the

The Exploratorium is testing new methods of using Internet-based programming to increase the public understanding of current scientific research. Exploratorium staff, working with a group of advisors, will assess the current status of projects that focus on conveying information about research. They then will develop and test a prototype website. The exploratory research will examine such questions as: What information about research is important and critical to convey to the public? How do you build a Web presence that can rapidly accommodate new findings? What is an appropriate oversight process to assure inclusion of appropriate research? What are sufficient update intervals? How does such a Web site build an audience? How can the Web effort be coordinated with other PUR projects? How can the Web site provide opportunities for public input and discussion? How do you develop buy-in and participation from researchers? Is the additional interpretation/annotation sufficient to give the public a deeper level of understanding? These planning and prototyping efforts will be coordinated with other simultaneous Public Understanding of Research planning projects.
The Exploratorium will develop "The Electronic Guidebook: Extending Museum Experience Using Networked Handheld Computers." Through this project, the Exploratorium and the Concord Consortium will investigate the use of new technologies to enhance the learning experience of science museum visitors. The exponentially increasing availability of portable personal computing devices provides an opportunity for science museums to develop new ways for visitors to experiment and interact with exhibits. The partners will design and prototype a museum-based "Electronic Guidebook" for visitors. Twenty-five Exploratorium exhibits will be connected to a museum network and handheld portable computers through infrared connections. The target audiences for this project are the general public (adults and families) and children in the K-12 age range. The primary disciplinary focus is physics, with a secondary focus on mathematics.
