Earth & Sky is a two-minute public radio science series about environmental sciences, earth sciences, and astronomy. As broadcast of the series expanded across the U.S., Multimedia Research implemented summative evaluations of listeners in three different radio markets. The evaluations focus on whether listening to the series influences adults' knowledge of, interest in, and attitudes toward science and whether the series affects listeners' science-related activities.
In this paper, the Franklin Institute's Ann Mintz discusses the managerial challenges associated with evaluation projects. Mintz explains how evaluators teeter on a continuum serving as both as artists and educators throughout the evaluation process. She cites evidence from an ongoing project at the Franklin Institute called the The Franklin Institute Computer Network that serves seven categories of museum visitors.
In domains with multiple competing goals, people face a basic challenge: How to make their strategy use flexible enough to deal with shifting circumstances without losing track of their overall objectives. This article examines how young children meet this challenge in one such domain, tic-tac-toe. Experiment 1 provides an overviews of development in the area; it indicates that children's tic-tac-toe strategies are rule based and that new rules are added one at a time. Experiment 2 demonstrates that even young children flexibly tailor their strategy use to meet shifting circumstances
The Franklin Institute Science Museum will develop, install and evaluate a museum-wide Interactive Computer Information System (ICIS) designed to enhance visitors' exhibit learning through museum-wide visitor information access and connectivity. ICIS will provide educational experiences for 1.2 million people per year, tailoring its information presentations to individual visitor needs and levels of knowledge. Exhibit based units will add advanced presentation functions beyond the usual graphics and text labels. ICIS will include 67 touchscreen-operated computer stations and six min- computers linking 27 exhibit areas in The Franklin Institute. This project is a collaboration between The Franklin Institute and the Unisys Corporation, which will provide over a five year period systems engineering, hardware, installation, maintenance and training of museum personnel valued at $2.4 million. An extensive evaluation plan will include studies of visitor-computer interaction, the economics and management of system maintenance, collaboration between museum and corporation and effectiveness of computer-based exhibit interpretation techniques. Project results will be disseminated through conference presentations, seminars and published articles.
Digital image processing offers several possible new approaches to the teaching of a variety of mathematical concepts at the middle-school and high-school levels. There is reason to believe that this approach will be successful in reaching some "at-risk" students that other approaches miss. Since digital images can be made to reflect almost any aspect of the real world, some students may have an easier time taking an interest in them than they might with artificial figures or images resulting from other graphics- oriented approaches. Using computer-based tools such as image processing operators, curve-fitting operators, shape analysis operators, and graphical synthesis, students may explore a world of mathematical concepts starting from the psychologically "safe" territory of their own physical and cultural environments. There is reason to hope that this approach will be particularly successful with students from diverse backgrounds, girls and members of minority groups, because the imagery used in experiments can easily be tailored to individual tastes. The work of the project consists of creating detailed designs of the learning modules, implementing them on microcomputers, and evaluating their effectiveness in a variety of ways, using trials with students at Rainier Beach High School, which is an urban public high school having an ethnically diverse student body and a Macintosh computer laboratory.

The Computer Museum in Boston, MA is requesting a SGER of $49,000 to support preliminary research into the use of virtual reality as a tool for informal science. Using a virtual reality environment of the human cell, they will test to determined: 1) if people gain a physical understanding of the human cell, including a sense of scale, the shape and location of elements, and the physical relationship between elements, and 2) if people gain an understanding of the concept of a system by interacting in the virtual world of the human cell. The PI will be David Greschler, Exhibit Developer at the Museum. He has developed two major exhibits at the Museum, has worked at the MIT Media Laboratory, and has taught educational software design at the Harvard Graduate School of Education. Eben Gay will be co-PI and will have oversight for the software development of the virtual reality. He has been Principal Engineer at Digital Equipment Corporation since 1980 and has been building virtual realities since 1982.
This is a study of the writing styles appropriate for describing science and nature television programs, thereby making them accessible to visually impaired audiences, and to access the audience's needs and preferences for science and nature programs.
