Prototype exhibits of "The Universe by the Powers of Ten" illustrated in three dimensions an exponential journey away from earth. The goal of the summative evaluation, implemented by Multimedia Research, was to assess the educational impact of the exhibits and accompanying interpretive techniques, for both non-school adult and teen samples and 6th grade school samples in the Maryland Science Center and the Montshire Museum of Science. Two interpretive conditions were compared - a printed handout and an explainer presentation. Further, the Montshire non-school sample experienced a third
Informal learning in math, science, and technology is an increasingly important vehicle for educating the public. Throughout their lifetime, the average citizen will spend a much greater amount of time in informal learning environments than in school. For these efforts to continue without benefit of understanding, the dynamics of what makes informal learning experiences work, is a waste of valuable funding resources. Research Communications Ltd. (RCL) proposes an effort to investigate what has been learned about informal learning in math, science, and technology and to develop some directions for future research in this important area. The first step in the process would be to review the existing literature in the three primary areas of informal education for math, science, and technology: television/radio, community projects, and science museums and technology centers with a focus on evaluation studies that have shown what strategies have worked and those that have not. The outcome of this effort would be a comprehensive publication of what is currently known about informal learning research in math, science and technology.
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.
