The Rhetoric of the Probable in Scientific Commentaries: The Debate Over the Species Status of the Red Wolf

This article looks at the commentary's role in scientific disputation by analyzing the rhetoric in two scientific papers. First, it considers each author's explanation as to why disagreement exists among scientists. Second, it investigates one author's accusation that “cultural norms” have foreclosed research avenues in evolutionary studies. Third, it examines each author's appeal to values. These values cohere with their explanations as to why disagreements exist and their particular recommendations for administrating the Endangered Species Act.     

A Case Study of Teacher Beliefs on Students' Beliefs about Multiple Representations

The mathematics education community, in its call for reform, underscores the importance of mathematics instruction emphasizing the use of multiple representations in the presentation of concepts. The focus of the study was how teacher beliefs affect their ability to implement a multiple representations curriculum. The novice instructor's attitude remained neutral while the experienced instructor's attitude remained somewhat positive. Of the eight students in the study, six of them showed a more positive attitude towards technology use and multiple representations by the end of the semester. The students increased their calculator use in both classes, particularly in the experienced teacher's class. Implications for further research were that teacher training is essential if reform curricula are to be properly implemented.     

The Rise and Fall of Innovative Education: An Australian University Case Study

From 1980 to 1995, the University of Western Sydney at Hawkesbury (formerly Hawkesbury Agricultural College) in Richmond, New South Wales, Australia, pioneered an innovative undergraduate degree in Systems Agriculture based on experiential education, systems thinking, and adult learning theory. Today this program is in trouble and has reverted back to a more traditional teacher-directed approach. This article discusses the rise of the innovative education paradigm at Hawkesbury, the unique Systems Agriculture program itself, and its eventual decline. Reasons for both the shift to innovative education and its eventual downfall are explored. Implications for institutions of higher education contemplating innovative educational approaches are suggested.

Measuring spontaneous and instructed evaluation processes during Web search: Integrating concurrent thinking-aloud protocols and eye-tracking data

Web searching for complex information requires to appropriately evaluating diverse sources of information. Information science studies identified different criteria applied by searchers to evaluate Web information. However, the explicit evaluation instructions used in these studies might have resulted in a distortion of spontaneous evaluation processes. Accordingly, the present study compared explicit evaluation instructions and neutral thinking-aloud instructions. Data from thinking-aloud protocols, eye tracking, and information problem-solving were collected from 30 participants equally distributed to two experimental conditions, that is, the Instructed Evaluation condition and the Spontaneous Evaluation condition. Instructed evaluation, as compared to spontaneous evaluation, resulted in more verbal utterances of quality-related evaluation criteria, in an increased attention focus on user ratings displayed on Web pages, and in better quality of decision making, although participants in the Instructed Evaluation condition were not able to better justify their decision as compared to participants in the Spontaneous Evaluation condition.     

Prospects for improving research communication and the incentive system in science

Much concern has been expressed in recent years about the processes associated with publishing research in high-profile journals,particularly within the life sciences and biomedicine[1-4].Researchers are frequently subjected to substantial delays in communicating their work,overzealous reviewers make demands for extensive revision,and essential information and data are often relegated to supplementary files with little functionality.More broadly,much of this work is not published open access,and the quality and reliability of the science that is being reported in top-ranking journals has been called into question[5,6].     

Reframing Service-Learning as Learning and Participation With Urban Youth

This article describes a critical service-learning project that resulted from an educational partnership among a national teachers' union, a local teachers' union, and a major research university. The partnership—funded by a grant from the Corporation for National and Community Service, Learn and Serve program—focused on professional development opportunities for K–12 educators across subject areas throughout an urban school district. Teachers enrolled in a university-level graduate course where they learned about critical service-learning, engaged in community-based activities, developed partnerships with local organizations, and facilitated critical service-learning projects in local schools and communities. Here, we highlight one of the many projects that emerged from this partnership as we attempt to connect theory with practice by reframing service-learning as learning and participation. We ask: How can a reframing of service-learning as learning and participation impact how we understand the educative and social engagements of four urban youth?     

Between a rock and a hard place: women and computer technology

This paper explores certain possible reasons behind the uneasy relationship between women and technology. The cultural identification of technology with masculinity has been well documented through previous research. However, we feel it is useful to revisit this complex relationship through the scope of a more subtle distinction between ‘users’ and ‘connoisseurs’, and the struggle over power, which revolves around a specific form of hegemonic masculinity. We draw on interviews that examine students’ experiences, emotions, and statements about gender, technology, mathematics, and education, and we try to offer an understanding of the ways women negotiate their position within the dominant discourse about computing and mathematics. Our analysis employs post-structuralist discourse theory.     

ALTERNATIVES IN AURAL REHABILITATION: PROVIDER TRAINING OF NONAUDIOLOGISTS IN THE DELIVERY OF HEARING‐AID SUPPORTIVE SERVICES TO OLDER PERSONS WITH HEARING LOSS

Recently, Patterson and Dancer (1987) suggested a model wherein persons who normally come in contact with older hearing‐impaired persons can be trained to assist the older hearing‐aid user in adjustment to amplification. Their four‐phase educational model offers an alternative to traditional aural rehabilitation programs by using personnel from senior centers, nursing homes, and state and local agencies as program providers.

The present article elaborates more fully on the training that protocol providers will receive from audiologists certified by the American Speech‐Language‐Hearing Association. Providers will be carried through five stages: empathy, effective communication skills, knowledge of the interaction of aging and hearing loss, the phases outlined in the Patterson and Dancer model, and guidelines for referrals. Objective‐based provider and client response criteria are outlined for moving the client from the initial receipt of the hearing aid to its ultimate acceptance and use on a doily basis.
