A typology of school science models

Modelling is the essence of thinking and working scientifically. But how do secondary students view science models? Usually as toys or miniatures of real-life objects with few students actually understanding why scientists use multiple models to explain concepts. A conceptual typology of models is presented and explained to help teachers select models that are appropriate to the conceptual ability of their students. The article concludes by recommending that teachers model scientific modelling to their students, encourage the use of multiple models in science lessons, progressively introduce sophisticated models, systematically present in-class models using the Focus, Action and Reflection (FAR) guide and socially negotiate all model meanings.     

Instruction in radio and television in twenty‐five selected universities

The mushroom growth of radio and television instruction taking place since the end of World War II has left in its wake a patch‐work guilt of academic programs in colleges and universities from coast to coast. The importance of trying to answer the question ‘Where are we going?”; indicates a need for realistic stock‐taking and thorough curriculum evaluation.

In keeping with its policy of seeking to advance the field of knowledge as to education for broadcasting, the Journal presents a special report on the current state of the curriculum which, it is hoped, will prove of value to all those interested in education for broadcasting.     

A Critique of Internet Polls as Symbolic Representation and Pseudo-Events

The Internet continues to grow as an information and entertainment medium. Internet growth has implications for the news industry. Twenty-four hour news networks such as CNN and MSNBC regularly encourage viewers of their television programs to visit their Web sites. While visiting news Web sites, visitors are invited to participate in opinion polls. Unfortunately, these online opinion polls are not scientific and have little real news value. In spite of these limitations, news Web sites' Internet polls are often treated as serious topics in broadcast news discussions. This article examines media organizations' Internet online polls and critiques them as instances of symbolic representation and pseudo-events that have arisen largely out of the integration of print, broadcast, and Internet media.     

Ombuds processes and disputant reconciliation

Effective dispute resolution systems are critical to the functioning of large universities and organizations. However, the design of dispute resolution systems is often inadequate to achieving the stated goals of the system. Analysis of the cases of 45 disputants reveals how the design of a university dispute system and the social context can prevent an ombudsperson from successfully reconciling relationships. This study shows how a dispute system that generally failed to utilize face-to-face meetings or mediation techniques between disputants in a social context of fear and limited social ties was unable to reconcile or preserve working relationships. Analysis from normative pragmatic and social contextual approaches to disputing provides a mechanism for understanding the problems encountered by this ombudsperson and provides a tool for designing more effective dispute resolution systems.     

'Talking about my generation': a state-of-the-art review of health information for men in the andropause

The focus of this article is the availability and use of information in the UK about the male menopause or as it's beginning to be known by the general public and health professionals, the andropause. The experiences of men suffering from the andropause today are reflective of menopausal women some 20 or 30 years ago. Ignorance and fear of the andropause condition abounds in the general public and amongst health professionals. There is a paucity of information in the literature about the symptoms and condition of the andropause. The review considers the provision and use of information available for men in the andropause in the public domain, examining both NHS and condition specific sources. The use of electronic sources is specifically reviewed, including an online forum. The use of electronic sources is indicative of other health information users. The reviewer concludes by suggesting that increased knowledge sharing is required by health professionals and the general public about the symptoms and condition of the andropause. It is recommended that men in the andropause identify a 'champion' to assist their cause. This will help in gaining greater recognition and understanding of the condition and attract the most appropriate treatment.     

“...If I Had a Choice,I Would....” A Feminist Poststructuralist Perspective on Girls in Physical Education

A significant number of studies evidence girls' lack of participation in physical education. This study used feminist poststructuralism to examine the ways in which high school girls participated in or resisted physical education. Using qualitative research methods, researchers collected field notes, informal interviews, and formal interviews with the teacher and 15 female students. In contrast to previous studies, girls in this study enjoyed and valued physical activity. As active agents, they chose to participate in or resist specific physical activities through their negotiations of gender relations. Physical education classes emerged as a contested terrain in which girls supported the notion of equal opportunity in physical activity but perceived limits on their choices in physical education as compared to male peers.     

Non‐numeric Intrajudge Consistency Feedback in an Angoff Procedure

The credibility of standard‐setting cut scores depends in part on two sources of consistency evidence: intrajudge and interjudge consistency. Although intrajudge consistency feedback has often been provided to Angoff judges in practice, more evidence is needed to determine whether it achieves its intended effect. In this randomized experiment with 36 judges, non‐numeric item‐level intrajudge consistency feedback was provided to treatment‐group judges after the first and second rounds of Angoff ratings. Compared to the judges in the control condition, those receiving the feedback significantly improved their intrajudge consistency, with the effect being stronger after the first round than after the second round. To examine whether this feedback has deleterious effects on between‐judge consistency, I also examined interjudge consistency at the cut score level and the item level using generalizability theory. The results showed that without the feedback, cut score variability worsened; with the feedback, idiosyncratic item‐level variability improved. These results suggest that non‐numeric intrajudge consistency feedback achieves its intended effect and potentially improves interjudge consistency. The findings contribute to standard‐setting feedback research and provide empirical evidence for practitioners planning Angoff procedures.     

Sustainable Procurement: Integrating Classroom Learning with University Sustainability Programs

Organizations are facing increased pressure from various stakeholders to address issues of sustainability, resulting in a growing demand for sustainability education and training. Procurement groups remain the key drivers of many sustainability‐related strategies, placing pressure on universities to integrate sustainability concepts into the business curriculum. This article describes a replicable educational model that allows students to learn about sustainable procurement while concurrently promoting sustainability within the university community.     

Comparing Models of Nature of Science Dimensionality Based on the Next Generation Science Standards

Instruments measuring understanding of the nature of science (NOS) are required if educational institutions intend to use benchmarks or examine the effects of interventions targeting students’ NOS development. Compared to other constructs, NOS understanding is complex, having been the subject of debate among scholars in both its substance and its dimensionality. This complexity invites challenges in defining what is to be measured. Drawing from the perspective that policy reform documents provide pragmatic consensus-based definitions of NOS, this study investigated how well the dimensionality described in the NOS component of the Next Generation Science Standards (NGSS) framework matched the empirical structure of data collected from a set of secondary-school students’ responses to an NOS instrument comprising multiple-choice and Likert-scale items. Using multidimensional item response modeling to compare structures of NOS dimensionality, we found that treating NOS as comprising multiple dimensions—as defined by the themes in the NGSS NOS framework—resulted in a better fitting model than when treating NOS as a single dimension. The multidimensional model also had fewer poorly functioning items and revealed NOS profiles that otherwise would have been masked in a model treating NOS as a single dimension. These results provide support for the NOS NGSS framework and contribute to the ongoing discussion about the dimensionality of NOS.
