This paper discusses the methodologies, key findings, and implications of a research project that examined the effectiveness of exhibits for making children understand scientific concepts. The two-part study was conducted at Nehru Science Centre (Bombay, India).

This is a brief summary of Barbara Birney's 1988 article featured in "Environment and Behavior," which discussed key findings from the formative evaluation of Brookfield Zoo's "Flying Walk" exhibit. The exhibit was designed to teach visitors the proper wing movement of birds.
In this brief article, Ruth Freeman summarizes a report of ongoing evaluation efforts of the effectiveness of the Discovery Gallery at the Royal Ontario Museum.
In this article, University of Wisconsin-Milwaukee researchers Dawn D' Amico and Wendy Pokorny discuss findings from their study that investigated the impact of a museum visit on preconceived notions of scientific explanation. D' Amico and Pokorny found that visitors' preconceptions were unlikely to change as a result of viewing exhibits.
Hands-On Science Outreach, Inc. has for a number of years developed and operated recreational after school and Saturday Science Classes for children, at first in Montgomery County, MD; and subsequently, with NSF support, at more than 22 sites around the country. During the last 10 years, they have reached more than 20,000 students with their unique collection of hands-on science activities. The project is well on the way to becoming self sufficient, and this final award will document both the philosophy of instruction and specific teaching methods that they have used and provide a third party evaluation of the processes of learning that they encourage in informal science education programs. Hands-On Science Outreach, Inc. will publish two 32 page booklets outlining their history, philosophy, and methods, and will conduct a third party evaluation of classes in four demographically diverse sites around the country, carried out under the direction of Dr. Harris Shettel, a nationally recognized informal education researcher. The resulting reports and publications will be widely disseminated, providing valuable information to others planning to offer hands-on science activities for children.
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.
The investigation of naive conceptions of science has many implications for both teaching and learning. The predominant model for past investigations has been with school children or within very formal settings. Extending investigations of misconceptions to informal settings is the challenge of this research. Museum visitors' misconceptions about two topics, gravity and mechanical advantage, will be recorded through a variety of interview formats. Twenty-five persons from each of the age ranges 9-11, 12-14, 15-18, and college students/adults will be interviewed. Information from the interview will be used to modify the current exhibit or to build new prototypes. The research will determine if a modification can be made that results in individuals moving from their previous misconceptions toward a correct conceptualization of the concepts. This research will document what individuals actually learn from museum exhibits and how "front end evaluation" can be used to redesign exhibits for maximum concept learning. The proposed research is challenging and has the potential of adding significant information to science education research on misconceptions. The principal investigator is highly respected in the field of museum education and the associated staff and consultants are the top scholars in their respective fields.
The proposers will organize and conduct the first of what is hoped will become an Annual Symposium on Children's Science Books that will focus national attention on this important and overlooked channel for science literacy. This first two day symposium will involve 75 editors, authors, librarians and educators in an intensive exploration of science books intended as independent or collateral reading materials for children at home, classroom or library. A national advisory committee will help shape the symposium's content. Professional and popular articles and a book will disseminate the results of the meeting. This project will explore an often-overlooked area of popular science education, and will involve science researchers committed to participating in improving popular education and communication in science. NSF support will be supplemented by university funds and income from the symposium.
