Abstract Distance education planners make complex decisions that result in substantial investments and have long‐term implications. This article provides a framework to categorize planning issues into four distinct program stages and three decision areas. The framework brings to the surface and highlights numerous areas of uncertainty and potential disagreement among decision makers and provides an organizing backdrop to improve the distance education planning process. 相似文献

Teachers’ content-related knowledge is a key factor influencing the learning progress of students. Different models of content-related knowledge have been proposed by educational researchers; most of them take into account three categories: content knowledge, pedagogical content knowledge, and curricular knowledge. As there is no consensus about the empirical separability (i.e. empirical structure) of content-related knowledge yet, a total of 134 biology teachers from secondary schools completed three tests which were to capture each of the three categories of content-related knowledge. The empirical structure of content-related knowledge was analyzed by Rasch analysis, which suggests content-related knowledge to be composed of (1) content knowledge, (2) pedagogical content knowledge, and (3) curricular knowledge. Pedagogical content knowledge and curricular knowledge are highly related (rlatent?=?.70). The latent correlations between content knowledge and pedagogical content knowledge (rlatent?=?.48)—and curricular knowledge, respectively (rlatent?=?.35)—are moderate to low (all ps?<?.001). Beyond the empirical structure of content-related knowledge, different learning opportunities for teachers were investigated with regard to their relationship to content knowledge, pedagogical content knowledge, and curricular knowledge acquisition. Our results show that an in-depth training in teacher education, professional development, and teacher self-study are positively related to particular categories of content-related knowledge. Furthermore, our results indicate that teaching experience is negatively related to curricular knowledge, compared to no significant relationship with content knowledge and pedagogical content knowledge. 相似文献

Audiences are what lend the “social” to social media. However, not all publics are equally welcomed by social media users, especially personal bloggers. Blog authors frequently exclude particular groups or types of people from their online content. As they negotiate the interplay of audience and blog, authors continuously create and destroy mediated publics, which are an important feature of the contemporary public/private distinction. The ways in which they manage those publics depend on the interplay of content and audiences. The creation and exclusion of numerous mediated blog publics illustrates a shift in the public/private distinction. 相似文献

For this study the researchers used data from the 2006 North Carolina Teacher Working Conditions survey to investigate the possible relationship between mentoring and intentionality with respect to beginning teachers’ intentions to remain in the profession. The sample consists of 8838 teachers who were mentored during their first two years of teaching. To determine whether the quality of mentoring is related to teachers’ intentions to stay or leave the profession, mentor matching, degree of support, and frequency of interactions were variables examined. Beginning teachers who were matched by grade level, who received assistance with the supports investigated, and who met with mentors at least once monthly for the specified activities were more likely to commit to remaining in the profession than their peers who had received less support. 相似文献

In this article, we build on arguments in risk communication that the predominant linear risk communication models are problematic for their failure to consider audience and additional contextual issues. The “failure”; of these risk communication models has led, some scholars argue, to a number of ethical and communicative problems. We seek to extend the critique, arguing that “risk”; is socially constructed. The claim for the social construction of risk has significant implications for both risk communication and the roles of technical communicators in risk situations. We frame these implications as a “critical rhetoric”; of risk communication that (1) dissolves the separation of risk assessment from risk communication to locate epistemology within communicative processes; (2) foregrounds power in risk communication as a way to frame ethical audience involvement; (3) argues for the technical communicator as one possessing the research and writing skills necessary for the complex processes of constructing and communicating risk. 相似文献

Nearly a decade ago, Sullivan presented her interpretation of the four generations of community college leaders by describing them as “the founding fathers, the good managers, the collaborators, and the millennium generation” (Sullivan, 2001, p. 559). She predicted a shift to frames utilizing the Four-Frame Model of Leadership by Bolman and Deal (1991). This article provides a discussion of the research that has been published using the Bolman and Deal model and a synopsis of the current leadership challenges faced by community college leaders. And finally, a new prediction is made of the values, skills, and frames needed for these leaders. 相似文献

Abstract Even though e‐commerce almost disappeared from public discussion, it still assumes a vital role in the strategic management of most enterprises. New entry in e‐commerce, whether as a new business segment of an established company or as a new enterprise, is likely to deal with the liabilities of size and newness. The aim of this paper it to discuss if those factors have an impact on the implementation and success of B2C e‐commerce. We chose the online book market as our reference market and drew a random sample of retailers and publishers with an online shop. The quality of the web presence, indirect success (number of links to a particular site) and direct success (turnover of the web shop) were compared in subsamples constructed by the use of median splits according to age and size. Younger companies and larger companies were found to have a web presence of higher quality and were more successful than older or smaller companies. We conclude that the liabilities of newness do not seem to have an adverse performance impact in e‐commerce. However, when a market entry is considered, new players must ensure that they can commit enough resources to build a high quality web presence. 相似文献

Government agencies are gradually moving from simpler towards more sophisticated and complex practices of social media use, which are characterized by important innovations at the technological, political and organizational level. This paper intends to provide two contributions to the current discourse about such advanced approaches to social media exploitation. The first is of practical nature and has to do with assessing the potential and the challenges of a centralized cross-platform approach to social media by government agencies in their policy making processes. The second contribution is of theoretical nature and consists in the development of a multi-dimensional framework for an integrated evaluation of such advanced practices of social media exploitation in public policy making from technological, political and organizational perspectives, drawing from theoretical constructs from different domains. The proposed framework is applied for the evaluation of a pilot consultation campaign conducted in Italy using multiple social media and concerning the large scale application of a telemedicine program. 相似文献

ABSTRACT The tremendous increase in the availability of full text electronic resources has been particularly beneficial to distance education students who do not have easy access to print collections. However, Western Michigan University (WMU) has been experiencing a decrease in requests for traditional document delivery of print based materials. This article presents a case study of WMU document delivery services for the distance education community. A survey was also conducted of libraries serving distance education programs to determine whether other institutions are also experiencing a decrease in usage of document delivery. Survey results show a more universal trend toward decreasing requests for delivery of print based articles; book requests are also decreasing but not at the same rate. The article concludes with some possible reasons for the decrease in usage of document delivery for distance education. 相似文献

Italian state museums are characterised by a rigid bureaucratic structure and are almost completely financed by government
transfers. In this paper we develop a simplified two-stage model in an attempt to explain how the government's preferences
for differentiated museum functions may affect museum organisation. The model shows that the government prefers that complementary
functions (e.g., conservation and scientific research) be produced by a single museum, whereas it prefers that substitutable
functions (e.g., conservation and access by the general public) be produced by two museums. We use this prediction for an
empirical analysis of the organisational structure of Italian state museums.
On the basis of the unique ISTAT census of the Italian museum system, we test with two separate probit models the probability
of observing in a state museum the concentration of either scientific activities of conservation and research or promotion
activities for education and the general public. Higher classes of centralisation for the state museums are also considered
by means of an ordered probit model. The results seem to suggest that the Italian state museum structure, as surveyed in the
early 1990s, fully reflected the traditional policy model viewing museums as institutions devoted to conservation, scientific
research and education.
