Doing a science project: Gender differences during childhood

By adolescence, men's participation and achievement in science exceeds women's. This article reports a case study that examined the beginnings of this gender differentiation during a naturally occurring academic activity that was designed to support and guide young children's interest in doing science. Data were collected during 2 successive years of a science fair for children in Grades 1–6 of a progressive private school. A total of 268 projects were characterized in terms of achievement and area of science. Parents provided information about the way children selected and created projects. In both years and in all grade levels, boys tended to choose to work in the physical sciences, and girls in the biological and social sciences. Peer collaborations were exclusively same sex. Achievement and parental involvement were not gender related. Factors are discussed that might lead to an early divergence of boys' and girls' interests in science within a context that promotes its exploration. © 1998 John Wiley & Sons, Inc.

Square Peg in a Round Hole? The Framework for Information Literacy in the Community College Environment

Column Editor's Note. Community college libraries are deeply underrepresented in the professional literature and organizations of academic librarianship. As a result, the challenges and successes that take place in the community college world are largely invisible to others. This JLA column lifts the curtain to reveal the uniqueness of community college libraries as described by their most passionate advocates: the librarians who work there. Articles in this column pay tribute to the commitment and creativity of community college librarians by providing a platform where they can share their professional perspectives and stories.

Standards, frameworks, or threshold concepts? The Association of College &; Research Libraries’ efforts to update and revise the Information Literacy Competency Standards for Higher Education (2000) have opened extensive dialogue not only about the content of the new standards, but about the very nature of the document. Its proposed replacement, The Framework for Information Literacy in Higher Education (2014) took a more theoretical path to describing what an information literature individual understands and how they behave. One common objection to the Framework, however, is that it is too advanced to be applicable in the undergraduate environment, and particularly in community colleges. In this essay, a community college library director takes a critical approach to the Framework to assess its relevance to the two-year college curriculum, grounding the discussion by mapping Knowledge Practices to Performance Indicators in the original Standards. The author recommends that community college librarians take an à la carte approach and integrate relevant elements of the Framework where they are useful without trying to address the entire document.     

Institute of Food Technologists (IFT) Education Division Competition 2013 Winner‐A Consumer's Guide to Probiotics: A Glimpse into the Big Picture of a Microscopic World

One of the core competencies in the Institute of Food Technologists (IFT) education standards is for students to achieve competency in communication skills (that is, oral and written communication, listening, interviewing, and so on). According to the IFT guidelines, by the time students graduate, they should not only be able to search for and condense information, but also be able to “communicate technical information to a nontechnical audience.” The Education Division of IFT sponsors a writing competition for undergraduate students to bring attention to and promote the development of communication skills. It has been shown that employees/entry‐level scientists who can communicate technical and nontechnical concepts succinctly will be in a better position to achieve management status after entering the work force. Monetary prizes are awarded to the authors of the top three papers. A revised version of the winning entry is published in the Journal of Food Science Education for dissemination to a world‐wide audience.     

The role of response-reinforcer correlation in signaled reinforcement effects

In three experiments, we examined the effects of signaling reinforcement during operant responding in order to illuminate the factors underlying instrumental overshadowing and potentiation effects. Specifically, we examined whether signaling reinforcement produces an enhancement and attentuation of responding when the response-reinforcer correlation is weak and strong, respectively. In Experiment 1, rats responded on variable-ratio (VR) or variable-interval (VI) schedules that were equated for the number of responses emitted per reinforcer. A signal correlated with reinforcement enhanced response rates on the VR schedule, but attenuated response rates were produced by the signal on the VI schedule. In Experiment 2, two groups of rats responded on a VI schedule while the two other groups received a conjoint VI, negative fixed-ratio schedule in which the subjects lost the availability of reinforcements if they emitted high response rates. A reinforcement signal attenuated responding for the simple VI groups but not for the animals given the negative fixed-ratio component, although the signal improved response efficiency in both groups. In Experiment 3, a poor correlation between responding and reinforcement was produced by a VI schedule onto which the delivery of response-independent food was superimposed. A signal for reinforcement initially elevated responding on this schedule, relative to an unsignaled condition; however, this pattern was reversed with further training. In sum, the present experiments provide little support for the view that signaling reinforcement enhances responding when the response-reinforcer correlation is weak and attenuates responding when this correlation is strong.     

The roots of gender inequity in technical areas

This article describes a study of the academic self-concepts, attributions and achievements of male and female Asian American and Caucasian students who won Westinghouse Awards in 1984 and 1985. The results of the study showed that fewer Caucasian female recipients anticipated college majors in the technical areas. Furthermore, this group of females scored lower on both parts of the SAT, scored lower on all of the self-concept scales, and also scored lower on both attribution scales. In contrast, the Asian females optimized courses for the gifted and specialized research courses to distance themselves from the American females in almost all areas. The author linked these ethnic, gender differences to underlying psychological and sociological forces that are responsible for the self-concept and attribution differences. It is these forces that must be altered for Caucasian females to rectify the gender inequalities that exist in the technical areas.     

Face processing in infancy: developmental changes in the use of different kinds of relational information

Adults use both first-order, or categorical, relations among features (e.g., the nose is above the mouth), and second-order, or fine spatial relations (e.g., the space between eyes), to process faces. Adults' expertise in face processing is thought to be based on the use of second-order relations. In the current study, 5-month-olds detected second-order changes, but 3-month-olds failed to detect second-order changes induced by 2 different manipulations. Three-month-olds did detect first-order changes, however. Also, inversion affected 5-month-olds' processing of second-order but not first-order information. These results suggest that, although sensitivity to first-order relations is available by 3 months or earlier, sensitivity to second-order information may not develop until sometime between 3 and 5 months of age.
