基于Wikipedia的资源型化学教与学   总被引:2,自引:0,他引:2  
Wikipedia是基于Wiki技术的目前全球最著名的英文网络百科全书,它利用超级链接构建化学信息网络,展现大量的化学知识及与相关情境素材,鲜明体现了Web2.0特征.基于Wikipedh的丰富化学资源,可以应用于新课程教学备课、化学主题科普论文写作,更可应用于开展多元化的化学教学活动.  相似文献

据CNN报道,百科全书式网站Wikipedia.com 现已成为一个很热门网站。和其他百科全书网站不同,该网站是由网友提供材料编写的。该网站是一个免费的百科全书式网站,内有十四万多篇文章,是由世界各地的网民提供的。Wikipedia网站不但免费易用,而且还允许使用者添加或编辑新的内容。“Wik”是夏威夷土语“快”的意思,该网站提供给使用者快速、方便的方法来出版自己写的文章,也可以允许有不同的写作风格。以两个香港大学的学生Abbie Wong(王)和Olivia Yuen(阮)为例,他们将介绍香港海域沿岸风景的文章放到Wikipedia去了。Wong写了有关中华白海…  相似文献

Internet usage logs captured during self‐directed learning sessions were used to determine how undergraduate medical students used five popular sites to locate and access biomedical resources. Students' perceptions of each site's usefulness and reliability were determined through a survey. Google and Wikipedia were the most frequently used sites despite students rating them as the least reliable of the five sites investigated. The library—the students' primary point of access to online journals—was the least used site, and when using Google less than 40% of pages or resources located by students were from ‘high’ quality sources. Students' use of all sites' search tools was unsophisticated. Despite being avid users of online information and search tools, the students targeted in this study appeared to lack the requisite information‐seeking skills to make the most of online resources. Although there is evidence that these skills improved over time, a greater emphasis on information literacy skills training may be required to ensure that graduates are able to locate the best available evidence to support their professional practice.  相似文献

In traditional classrooms, a textbook was often the only source of knowledge available; in stark contrast, today's classrooms have an infinite number of knowledge sources available through the Internet. Nevertheless, a range of studies suggest that students systematically favor Wikipedia in their school-related literacy practices. The present study investigates this tendency among students in upper-secondary school, using a survey with multiple choice and open-ended questions. The main finding suggests that students favor Wikipedia because the site provides them with what they need, being fast, flexible, and easy to use. At the same time, students are aware of credibility issues associated with Wikipedia. A discrepancy between students’ positive attitudes to including Wikipedia in their school-related literacy practices and their teachers’ lack of approval of this knowledge source is discussed.  相似文献
