This study addressed the questions of whether or not the IMAX/OMNIMAX film "Tropical Rainforest" contributes to a positive attitude towards, and and increase in knowledge about, the tropical rain forests of the world. Results indicate that there are statistically significant increases in knowledge gained as well as an increase in positive attitudes towards the tropical rain forests. All three specific audiences (grades 1-6; grades 7-12; adult general) tended to increase overall.
From the Proceedings of the 1992 Annual Visitor Studies Conference. Reviews a study, conducted as part of a formative evaluation of an HIV/AIDS exhibit developed by the New York Hall of Science, which was designed to investigate two issues: 1) What is the current state of youth awareness of the mechanisms by which condoms help prevent the spread of HIV and other sexually transmitted diseases; and 2) Which of two exhibit designs most efficiently communicates concepts related to HIV sexual transmission prevention. A copy of the survey used in the study is included in the appendix of this report.
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.
The middle-school and high-school years are a period of change and crystalization in terms of life goals, disciplinary and course preferences, and social and political attitudes. The literature provides a number of cross-sectional descriptions and models concerning cognitive and attitudinal development during adolescence and young adulthood, but there are no longitudinal data available to study these processes. The proposed longitudinal study will examine the (1) development of interest in science and mathematics, (2) the growth of scientific literacy, (3) the development of attentiveness to science and technology issues, and (4) the attraction to careers in science and engineering among two national cohorts of adolescents and young adults. One cohort will begin with a national sample of 3,000 seventh graders and follow them through the 10th grade. The second cohort will begin with a national sample of 3,000 10th graders and follow them for the next four years through the first full year after high school. Data will be collected from students, teachers, counselors, principals, and parents. A purposive sample of two or three school districts with exemplary elementary school science and mathematics education programs will be selected and comparable data will be collected in these districts. The analysis will consist of a series of expanding multivariate developmental models that will seek to understand cognitive and attitudinal growth and change in the context of family, school, and peer influences. Each wave of data collection will provide an opportunity to examine cognitive and attitudinal change measures in an increasingly rich context of previous measures. Periodic reports will be issued with each cycle of data collection and the data will be made available to other scholars on a timely basis. The first phase of the project, being funded at this time, provides approximately 15 months for instrument development and pilot testing, for sample selection, for monitor selection and training, and for working with the research advisory committee.
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.
