Investigating the effectiveness of a POE-based teaching activity on students’ understanding of condensation

This article reports on the development of a Predict–Observe–Explain, POE-based teaching strategy to facilitate conceptual change and its effectiveness on student understanding of condensation. The sample consisted of 52 first-year students in primary science education department. Students’ ideas were elicited using a test consisting of five probe questions and semi-structured interviews. A teaching activity composed of three Predict–Discuss–Explain–Observe–Discuss–Explain (PDEODE) tasks was employed, based on students’ preconceptions identified with the test. Conceptual change in students’ understanding of condensation was evaluated via a pre-, post-, and delayed post-test approach and students’ interviews. Test scores were analyzed using both qualitative and quantitative methods. The findings suggested that the strategy helps students to achieve better conceptual understanding for the concept of condensation and enables students to retain these new conceptions in their long-term memory.     

Perceived relational intimacy and relational message content

This study provides further validation of the relational message scales (Burgoon & Hale, 1987). The “preferred” relational message schema presented by Burgoon and Hale is shown to be internally consistent, reliable, and to reflect changes in communication as relationships increase in intimacy.

A Matter of Language or Culture: Coverage of the 2004 U.S. Elections on Spanish- and English-Language Television

This article fills a gap in the communication and political science literature by comparing how Spanish- and English-language television stations cover U.S. elections. A content analysis of more than 400 national network news stories and nearly 3,000 local news stories reveals that local and network Spanish-language stations provide less election coverage than their English-language counterparts. Although Spanish-language stations are more likely to focus election coverage on “Latino” issues or interests, the results indicate only moderate differences in how stations in each language frame their election stories, with stations in both languages concentrating more coverage around campaign strategy and the horse race than substantive issues.     

Meeting the E-Resources Challenge through Collaboration: An OCLC Perspective on Effective Management,Access, and Delivery of Electronic Collections

The session explored how collaboration among libraries, suppliers, and the OCLC Online Computer Library Center, Inc. (OCLC) cooperative can address some of the problems being faced with the management of electronic resources. Examples of specific challenges that impact budgets and services are: libraries’ reliance on multiple non-interoperable systems; the difficulties in getting and maintaining high quality and timely metadata; and the issues with managing workflows that cross system and staff boundaries. As work continues to introduce and enhance integrated systems for electronic resource management, these cooperative efforts can improve both the quality of the services and the associated data and workflows.     

Darwin’s Other Bulldog: Charles Kingsley and the Popularisation of Evolution in Victorian England

The nineteenth-century Anglican Priest Charles Kingsley (1819?C1875) was a significant populariser of Darwin??s theory of evolution by natural selection. Kingsley was successful in this regard because he developed such diverse connections throughout his career. In the 1840s he associated with Chartists and radical journalists; in the 1850s and 1860s he moved freely in scientific circles and was elected Fellow of the Linnean Society of London in 1856 and Fellow of the Geological Society of London in 1863. In 1859 he was appointed Chaplain in Ordinary to the Queen. In 1860 the Prince Consort was willing and able to secure Kingsley appointment as the Regius Professor of Modern History at Cambridge University and he subsequently became tutor to the Prince of Wales. Thereafter he was frequently invited into high Victorian Society. A friend of ??Darwin??s Bulldog?? Thomas Huxley, of the eminent geologist Charles Lyell and a correspondent of Darwin, at every turn he sought to promote Darwin??s ideas as theologically orthodox, a life-long campaign in which he was eminently successful.
