This paper shares research findings that explore the link between conceptual understanding, free exploration of hands-on science center exhibits, and Piagetian cognitive developmental levels. Implications on museum exhibits and field trip experiences are examined as well.
This article discusses a 1988-1990 study that analyzed the effectiveness of a collaborative effort between a museum and a school system to build an integrated curriculum package. The partners included the York County School System (VA) and the Yorktown Victory Center (operated by the Jamestown-Yorktown Foundation). The theme of the curriculum was 18th Century Medicine and the unit was designed to enhance the science, math, and social studies instruction of fourth graders.

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.
This research project is a follow-up to previous research on the persistence of high ability minority youth in college programs for mathematics, science, engineering, premedicine and predentistry. The earlier research used data retrieved from the 1985 College Board files for 5,602 students with SAT mathematical scores of 550 or above. All were minority students except for a comparison sample of 404 White students. In 1987, a first follow-up was conducted. 61 percent of the non-Asian American minority students had enrolled in college and were majoring in MSE fields in comparison with 55 percent of the White students and 70 percent for the Asian American students. In the current phase of this research, the original sample will be resurveyed, five years after high school graduation. A subsample will be interviewed in-depth. The major goal of this phase will be to answer three critical questions: which sample members are still studying or employed in MSE fields, what are their unique characteristics, and what are the theoretical and national policy implications of the results. This project is jointly supported by the Studies and Analysis and the Research in Teaching and Learning Programs.
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.
