Through the lens of discursive institutionalism, and drawing on an extensive corpus of metajournalistic discourse dating from 2000 to 2017, this study considers how journalists have defined and (re)constructed their gatekeeping role against the backdrop of seismic changes confronting their field. In so doing, it considers the legitimizing or delegitimizing discourses journalistic actors use when addressing journalism’s gatekeeping role. 相似文献

This study seeks to understand “listening” as a practice and norm of journalism in the context of an eruption of journalistic discourse about listening surrounding the 2016 US election. An examination of US journalists’ own discourse about listening pointed to an understanding of the need to listen more, better, and to a more diverse set of voices. The widespread criticism of journalism’s performance frequently pointed to failures of listening as a root cause of the more general failure to adequately cover the campaign. Thus, listening involved a set of skills, but was also sometimes construed as a moral obligation. Overall, however, the discourse showed an anemic understanding of listening, often pointing to the public’s inability to listen to journalists. 相似文献

Worldwide, a tendency is visible in which upper secondary science curricula are innovated in the direction of context‐based education. Crucial to these innovations is the way teachers interact with newly developed teaching materials and implement them in classroom practice. The focus of our research is to identify characteristics of the interaction between innovative context‐based materials and teachers that hinder or facilitate classroom implementation as intended by the designers. Four cases of classroom implementation by four experienced teachers with different degrees of experiences in context‐based education, all implementing ‘Chemie im Kontext’ (CHiK) teaching materials, were carried out using a previously developed framework for analysis. It was found that a crucial aspect of CHiK, that of taking students' questions and using them as an orientation as the ‘focal event’ for the following lessons, was difficult to implement. The employed contexts are too general and broad to be effectively applicable as a setting in which activities such as students developing their own ideas and exploring them logically take place. Therefore, it is recommended that extensive teacher professionalization is required on this aspect to show teachers its value and to increase their repertoire of necessary teaching activities. 相似文献

This study explains the history of a 1959 amendment to the 1934 Communications Act through the lens of historical institutionalism. The amendment created broad exemptions for newscasts, documentaries, interviews, and news events, triggering the equal time provision for candidates for public office. While this study offers a variety of new empirical details, the chief goal is explanation based on an examination of historical mechanisms—path dependence, critical junctures, agglomeration, asymmetries of power, reinforcement of expectations, and temporal sequencing—that shaped the policy options leading up to the amendment. 相似文献

Relating students' reasoning to the history of science: The case of chemical equilibrium 总被引：1，自引：0，他引：1
In this study, the reasoning of students, who are introduced to the concept of chemical equilibrium, was related to the historical
development of this concept. In the first stage of the study, remarkable similarities were observed between students' reasoning
on the issue of incomplete chemical conversions and the reasoning of 19th-century scientists, especially when molecular notions
were included. In the next stage of the study, some authentic problems and questions, that were essential in the historical
development of chemical equilibrium, were presented to students. It appeared that they recognised the significance of these
problems and questions. Moreover, most students were eager to find explanations. Students, reasoning in molecular terms, would
sometimes explain these problems in terms similar to historical explanations. Other students, however, suggested explanations
in non-molecular terms, which, although chemically valid, did not appear to have historical antecedents. It was concluded
that the study of authentic historical sources may inspire the design of effective teaching activities. 相似文献

This review summarizes and builds on a seminar about assessment of student learning in higher education. Assessment can be looked upon as simply something that has to be done at the end of a course. During the course of discussions at the seminar the participants became more aware of how assessment can have an impact on learning. This means that assessment can be used as a means to improve learning. This realization is not a new one, but it is highlighted here in a more coherent and concise way than usual. Many alternative methods of assessment are possible. Some instructional design rules will be presented here for designing assessment sessions in such a way that learning can be improved. When designing an assessment method, one can be guided by the following considerations. The content of assessment should be chosen in accordance with the learning outcomes one hopes to achieve. The organization of assessment can be designed in such a way that the desired learning process is promoted. The outcome of assessment can provide feedback to many of the stakeholders: to the students on their learning process; to the faculty on its outcomes; and to the teacher by pointing out the following steps to be taken in improving assessment, learning and teaching. 相似文献

ABSTRACTVocation, interpreted as the calling of every individual believer to serve God in ordinary life, has been an important feature of Protestantism. However, not only has the notion of vocation gradually disappeared from the late modern understanding of work and profession, the identification of vocation and work has also been criticized by theologians such as Karl Barth, Miroslav Volf, Jacques Ellul, and Gerrit de Kruijf. From their eschatological perspective, these theologians hold that because our true vocation is to be citizens of God's kingdom, work is a relative good or even a necessary evil. Although this criticism is in various respects justified and relevant, it tends to overlook the particularity of callings included in the Protestant conception of vocation. Therefore, an alternative approach is presented, in which vocation as a particular calling from God's side can be reconnected to everyday life, including the life sphere of work and profession. From this approach, this article explores the implications for discerning vocation in the practice of Christian higher education as a communal practice of discernment of one's callings, as related to the primary calling to be a citizen of the kingdom of God, and as aimed at the common good. 相似文献

Few historians of science would associate the Spanish Empire with scientific innovation. However, recent research is increasingly demonstrating the Crown's strong commitment to scientific research, particularly in the areas of botany, natural history and medicine. Although this commitment began in the 16th century, it reached full development in the 18th, when Enlightenment ideals led to growing interest in exploiting natural resources in the New World. Interest in new resources, which offered alternatives to silver and traditional cash crops, focused largely on medicinal herbs indigenous to the Americas. Herbs that provided 'miracle cures' for age-old diseases would bring both material and moral wealth to the Crown, and were thus pursued vigorously throughout Spanish America. The result was a search for an 'herbal' El Dorado, reminiscent of 16th-century expeditions in search of a mythical land of gold--only in this case, medicine, not metal, was the goal. 相似文献
