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

This volume explores the integration of recent research on everyday, classroom, and professional scientific thinking. It brings together an international group of researchers to present core findings from each context; discuss connections between contexts, and explore structures; technologies, and environments to facilitate the development and practice of scientific thinking. The chapters focus on: * situations from young children visiting museums, * middle-school students collaborating in classrooms, * undergraduates learning about research methods, and * professional scientists engaged in
The Informal Science Education Program has been supporting the radio series "Living on Earth" for several years. The World Media Foundation is now adding environmental science and technology features to "Living on Earth" and is developing and testing an outreach component that will involve youth as researchers and radio producers. The science and technology features, ranging in length from four to twenty-four minutes, will depart from the usual news-driven reports on the programs. Many of the segments will illustrate basic building blocks of environmental science, technology and related mathematics. Others will profile diverse pioneers in these disciplines. The radio programs will be the framework for an interdisciplinary exploration program for youth. Working with a team of educators from the Antioch University Graduate Program in Environmental Education, the project staff will develop a program in which secondary school aged youth cooperate with peers to produce professional, concise reporting on local environmental issues. Living on Earth will feature the best of the student work on National Public Radio and highlight these pieces as an expanded feature on its website.
BioTrac will expand opportunities in biomedicine for low-income, first-generation college-bound high school students, increasing the number interested in, and prepared to enter, the biomedical research pipeline. Specific objectives are to: (1) Raise awareness of careers in biomedicine and provide students with real-world biomedical research experiences; (2) Increase awareness of requirements and opportunities for related post-secondary study; (3) Increase public understanding of the importance and diversity of biomedical research; and (4) Disseminate project outcomes. In collaboration with the University of Miami (UM) and Miami-Dade County Public Schools (M-DCPS), the Museum will design and implement a replicable model program exposing students to research on selected priority areas outlined in the Public Health Service's Healthy People 2000 agenda. The program will focus on areas with significant local research capacity, ties to local growth industries, and relevance to Miami-Dade's diverse communities. Students will investigate each area through hands-on lab activities, on-line research, site visits to research facilities, and through interactions with research scientists at UM's nationally renowned Jackson Memorial Medical Complex. Students will work in teams to conduct community-focused research on aspects of each priority area, using technology skills acquired as part of the program to document their research through digital video, PowerPoint presentations, and development of a BioTrac website. Students will present their research at annual symposia held at the Museum. They will also serve as science explainers in the Museum's galleries, interpreting biomedical-related exhibits to the general public. During the summer before 12th grade, students will attend residential programs at University of Florida and Florida A&M University, gaining exposure to post-secondary programs leading to careers in biomedical research. Students in 11th and 12th grade will also be encouraged to participate in M-DCPS's Advanced Academic Internship Program, gaining up to three honors credits for work in institutions engaged in biomedical research. Following 12th grade, prior to beginning college, students will be placed in an eight-week summer internships at UM labs engaged in a broad spectrum of biomedical research. The Museum will disseminate students' research experiences and project findings through an BioTrac web page, ASTC and Upward Bound conferences and networks, and Museum and UM publications.
