Reduced Knowledge of Results Frequency Enhances Error Detection

Abstract

The purpose of the present study was to determine the effects of consonant and dissonant role playing with high or low justification on attitude change toward physical education courses. An analysis of the attitude of 311 college subjects before and after role playing showed that role playing in a physical education course produced an attitude change in the direction of the role played. Consonant role playing reinforced initial attitudes, but dissonant role playing resulted in a significantly greater change in the direction of the role played. Low justification tended to produce greater attitude change in the dissonant role playing, but high and low justification seemed equally effective in reinforcing a prior attitude in consonant role playing.     

Contemporary high-profile scientists and their interactions with the community

This article presents a case study of 10 high-profile Australian research scientists. These scientists are highly committed to engaging with the public. They interact with a wide range of groups in the community, including the traditional media. They are aware that they are seen as representatives of science at a time when the authority of science and scientists is threatened in Australia by controversy around issues such as climate change and vaccination. Through their experiences of interacting with non-scientists, they have developed views about qualities, characteristics and knowledge that contribute to, or inhibit, positive interactions between scientists and non-scientists. Their experiences and insights highlight aspects of contemporary science that are not generally acknowledged in science curricula.     

‘Becoming our own experts’: lessons from the past

This article reports on a local curriculum development project from the 1970s that shared many of the features of action research, though it was not thought of as such. Teacher control, the bridging of the theory–practice divide, the centrality of practitioner classroom research, and the quality of pupils' learning were all features of the project. The article also discusses the problematics of outsider involvement, of contributions to knowledge, and of authenticity.     

An Informed Look at Doctoral Vivas (Oral Examinations) in the Preparation of Counselor Educators

Viva voce is the Latin expression traditionally used to refer to doctoral oral examinations. Viva voce, or simply viva, examinations are a standard requirement for doctoral candidacy and degree completion in many counselor education programs. Despite the prevalent use of vivas as an assessment and learning tool, the counselor education literature is scant on information about their rationale, method, and impact. Current trends toward transparency and accountability in higher education now require that counselor educators and researchers take steps to ensure that the use of vivas is justified beyond tradition alone.     

“Wealth Makes Many Friends”: Children Expect More Giving From Resource-Rich Than Resource-Poor Individuals

Young children show social preferences for resource-rich individuals, although few studies have explored the causes underlying such preferences. We evaluate the viability of one candidate cause: Children believe that resource wealth relates to behavior, such that they expect the resource rich to be more likely to materially benefit others (including themselves) than the resource poor. In Studies 1 and 2 (ages 4–10), American children from predominantly middle-income families (n = 94) and Indian children from lower income families (n = 30) predicted that the resource rich would be likelier to share with others than the resource poor. In Study 3, American children (n = 66) made similar predictions in an incentivized decision-making task. The possibility that children's expectations regarding giving contribute to prowealth preferences is discussed.     

Suicidal Behavior and Help Seeking Among Diverse College Students

Suicidal and help‐seeking behaviors of students of color remain a significant problem on college campuses. Self‐reported suicidal experiences and help‐seeking behavior of diverse students are examined on the basis of results from a national survey of college student mental health. The results suggest significant differences in the expression of suicidal thoughts and behavior across racial and ethnic groups and different experiences in their referral for, and utilization of, professional help.     

Sources of self-efficacy beliefs of students in a technology-intensive asynchronous college algebra course

The purpose of this study was to explore the influence of the four traditionally hypothesized sources of self-efficacy on learners' self-efficacy beliefs regarding learning mathematics in an asynchronous environment. The context of the study was a college algebra and trigonometry course offered in an asynchronous, technology-intensive emporium model at a large, public university in the southeastern United States. Participants (N = 99) completed surveys assessing their self-efficacy to learn mathematics in this environment as well as to assess their mastery experiences, vicarious experiences, social persuasion, and physiological state. Regression analysis indicated that in this environment, the most important factors are vicarious experiences, followed by affective/physiological influences.     

Pharmaceutical prospects: biopharming and the geography of technological expectations

The paper explores the role of imagined geographies in the shaping of new technologies. I argue that the role of place in future-oriented visions of technoscience is a neglected topic in studies of the social shaping of technology. The paper proposes an approach that combines the sociology of expectations with the geography of science. It focuses on the interplay between envisaged and current geographies to highlight the recursive dynamics of place and imagination. To illustrate this approach, the paper discusses the example of biopharming, the production of biopharmaceuticals using genetically modified crops. I argue that expectations for biopharming bear the imprint of place, or rather of the places in which they are imagined, as well as those they imagine, and ultimately those they produce. I use this example to suggest how social studies of science and technology can usefully investigate the spaces, places and scales of technological development.

Reconstruction versus transformation: Post-war education and the struggle for gender equity in Sierra Leone

In post-war contexts, education is widely regarded as essential not only for civic reconciliation, but also as a key force for gender equity. In Sierra Leone, however, despite enhanced educational opportunities for girls, much of the emphasis on post-war educational reconstruction is unlikely to rectify gender inequities that remain entrenched within mainstream schooling and in the broader social context. Yet the capacity of education to contribute to gender-based change has not been entirely muted. Several women's associations are supporting girls’ education as integral to economic and political actions aimed at challenging the hegemony of patriarchy and gendered violence. What remains to be seen is whether these discrete efforts can foster a women's movement capable of altering the structures of patriarchal power in Sierra Leone.
