以历史的角度、国际的视野来观察,英国开放大学和美国大学水平考试体系(CLEP)与我国高等教育自学考试有很多相似的地方。作为国外成熟的教育形式和考试制度,英国开放大学和美国CLEP考试对我国的自学考试如何发展的重要借鉴意义是不言而喻的。文章将从开放性、经济性、学分、学历(学位)及助学等几个方面,对中、英、美三种教育模式进行比较,从而根据国际教育体系的一些特点和做法对我国自学考试的改革提出一些探索式的建议。  相似文献

《Journalism Practice》2013,7(1):51-67
The extent to which information sources, that stand behind virtually all the news, are perceived by journalists as credible is a key determinant of the likelihood of their obtaining news access and public voice. The nature of source credibility judgment in journalism, however, is disputed between two major schools: while the “visceral” camp contends that it is highly subjective, intuitive and biased, the “discretional” camp perceives it as a far more reasonable and legitimate journalistic tool. The present study attempts to uncover evidence of both “visceral” and “discretional” judgment by studying the conceptual credibility (trustworthiness ratings) and practical credibility (practices indicating trust or skepticism, such as cross-checking and attribution) and the congruence between the two in a sample of 840 news items based on 1870 news sources. Findings were gleaned in face-to-face reconstruction interviews with reporters from nine leading Israeli news organizations, who reconstructed, source by source, the processes behind their items, shortly after their publication. Pro-discretional evidence shows that while journalists perceive their own experience as more credible than that of any other human agent, they do tend to stick with sources they perceive as more credible, the majority of which were relied on in the past, granting them more ready acceptance. Pro-visceral evidence, in turn, demonstrates that even the least credible sources receive substantial news space, some without any cross-checking. Furthermore, reporters ranked their sources' credibility even when they had no former record of trustworthiness. The paper suggests interpreting the composite of these findings as discretional logic with islands of visceral judgment.  相似文献

Abstract

Two open source extensions to the Firefox browser, LibX and Zotero, can improve the research process for library staff and users. Once configured and installed, LibX provides Firefox users with an additional browser toolbar and right-click functionality that can search a library's catalog, OpenURL resolver or federated search engine, as well as other Web sites. LibX also includes an autolinking feature, which embeds searchable links within other Web sites such as Google, Amazon, or Yahoo. Zotero merges the best features of other citation management programs with those of popular Web 2.0 services. Zotero users can store full citation information and sort, tag, annotate, and search these citations from within the Firefox browser. Zotero can also “scrape” citations from certain Web sites, allowing users to selectively save citations into their research collection. Zotero can generate complete bibliographies in MLA, APA, and Chicago styles. The abilities to remotely store, synchronize, and share Zotero collections are under development with a planned release date in fall 2007.  相似文献

This study investigated the effects of argument scaffolding and source credibility on science text comprehension. Eighty-seven college students were randomly assigned to an argument scaffolding activity, or no scaffolding, and read 2 science texts, attributed to a high- or a low-credibility source. The argument-scaffolding group recalled less text-based information but generated more knowledge-based inferences than did the no-scaffolding group. High source credibility enhanced readers’ text-based recall but had little effect on knowledge-based inferences or situation models. Overall, results suggest that argumentation facilitates deeper text comprehension and better argument understanding, while at the same time reducing the effect of source credibility on text processing.  相似文献

This is a report of two studies that examined the association of receivers' perceptions of sources' levels of several communication traits (shyness, communication apprehension, verbal aggressiveness) with the receivers' reported levels of affect for the source (general affect and/or liking) and the receivers' perceptions of the sources' credibility (competence, trustworthiness, goodwill). Study 1 examined employees’ perceptions of their supervisor's communication trait behaviors in the organizational context, while Study 2 examined the students' perceptions of their roommate's communication trait behaviors in an interpersonal context. As predicted on the basis of previous theory and research, both perceived communication apprehension and perceived verbal aggressiveness of the source were found to be substantially negatively correlated with credibility and affect and/or liking reported by the receiver. Contrary to our hypothesis, perceived behavioral shyness was not meaningfully associated with either credibility or affect. It is concluded that these results provide important information for distinguishing between the theoretical constructs of shyness and communication apprehension and theory in this area in general.  相似文献
