Why are some youth more likely to think of themselves as a science kind of person than others? In this paper, we use a cognitive social-theoretical framework to assess disparities in science identity among middle school–age youth in the United States. We investigate how discovery orientation is associated with science interest, perceived ability, importance, and reflected appraisal, and how they are related to whether youth see themselves, and perceive that others see them, as a science kind of person. We surveyed 441 students in an ethnically diverse, low-income middle school. Gender and race/ethnicity are associated with science identity but not with discovery orientation. Structural equation model results show that the positive association between discovery orientation and science identity is mediated by science interest, importance, and reflected appraisal. These findings advance understanding of how science attitudes and recognition may contribute to the underrepresentation of girls and/or minorities in science.

AbstractCurrent research in virology is changing public conceptions about vaccines and infectious disease. The University of Nebraska State Museum collaborated with research virologists, science writers, artists and learning researchers to create public outreach materials about viruses and infectious disease. The project, funded by the National Institute of Health's SEPA program, developed comics, a book with Carl Zimmer, and other materials and programs. The project launched three kinds of learning research: 1) a survey of Nebraska adults on their opinions about vaccines and infectious disease; 2) a study comparing the mental models of viruses, vaccines, and infection from virologists, teachers, and students; and 3) a controlled study of 873 high school students randomly assigned to read either a comic or a text-based essay with the same virus information.

Empirical associations among co-adapted traits such as body size and patterns of reproduction, development, and behavior are unknown for most animal species, despite numerous theories suggesting otherwise. One way to study these complex relationships is first to consider closely related species and then to generalize findings to other groups. In the present study, relationships among body size, reproductive patterns, development, and sociality were examined in 17 members of the family Canidae (canids). Large canids are more social than smaller species, and offspring of large species achieve independence and tend to breed first at a later age. Large females give birth to absolutely larger young, but relative to their own body weight they allocate fewer resources to bringing a large pup to term. Overall, sexual dimorphism in size is small to moderate, and this is associated with monogamous mating habits and paternal care of young.

The article examines the programs for high school students at science museums that are full-members of the Association of Science-Technology Centers in the U.S. It discusses how science museums attract students interested in science to provide classes or academic preceptorships. The museums involved in the study include the Museum of Science in Boston, Massachusetts, the Buhl Science Center in Pittsburgh, Pennsylvania, and the Center of Science and Industry in Columbus, Ohio.
