PURPOSE: This study describes the system architecture and user acceptance of a suite of programs that deliver information about newly updated library resources to clinicians' personal digital assistants (PDAs). DESCRIPTION: Participants received headlines delivered to their PDAs alerting them to new books, National Guideline Clearinghouse guidelines, Cochrane Reviews, and National Institutes of Health (NIH) Clinical Alerts, as well as updated content in UpToDate, Harrison's Online, Scientific American Medicine, and Clinical Evidence. Participants could request additional information for any of the headlines, and the information was delivered via e-mail during their next synchronization. Participants completed a survey at the conclusion of the study to gauge their opinions about the service. RESULTS/OUTCOME: Of the 816 headlines delivered to the 16 study participants' PDAs during the project, Scientific American Medicine generated the highest proportion of headline requests at 35%. Most users of the PDA Alerts software reported that they learned about new medical developments sooner than they otherwise would have, and half reported that they learned about developments that they would not have heard about at all. While some users liked the PDA platform for receiving headlines, it seemed that a Web database that allowed tailored searches and alerts could be configured to satisfy both PDA-oriented and e-mail-oriented users. 相似文献

Learning is critical to both economic prosperity and social cohesion. E-government learning, which refers to the government's use of web-based technologies to facilitate learning about subjects that are useful to citizens, is relatively new, relevant, and potentially cost-effective. This work proposes and verifies that the technology acceptance model (TAM) can explain and predict usage of e-government learning. The TAM examines how perceived ease of use and perceived usefulness and their antecedents influence intention and usage of a system. This study identifies antecedents that account for individual differences, thereby enhancing the explanatory power of the built model. A survey is used to collect data from users of an e-government learning website in Taiwan. Structural equation modeling is employed to examine the fit of the data to the model. From a theoretical point of view, this research extends the TAM to e-government learning and identifies the perceived e-government learning value and perceived enjoyment as antecedents of usage of e-government learning. This study also provides directions for future research and approaches to promote e-government learning. 相似文献

The purpose of this study is to investigate the effects of computer-assisted videodisc-based anchored instruction on attitudes toward mathematics and instruction as well as problem-solving skills among Taiwanese elementary students. Results from a t-test indicate a significant main effect on student attitudes toward mathematics. Results from a two-way Repeated Measures ANOVA show that students' problem-solving skills improve significantly with anchored instruction. Results also indicate that all the students benefit from the effects of anchored instruction on their problem-solving performance regardless of their mathematics and science abilities. The findings suggest that video-based anchored instruction provide a more motivating environment that enhanced students' problem-solving skills. This study is significant because it establishes an example of video-based anchored instruction for Taiwanese students and also provides empirical evidence of its effects on affective and cognitive responses among fifth graders in learning mathematics. This study is helpful to educators who want to help students learn to think and learn throughout technology. 相似文献

People have long relied on storytelling for communicating ideas, transferring knowledge, and consequently making decisions.
This paper describes the design and development of a case-based reasoning (CBR) knowledge repository including its case library
and the search engine to support the technology integration community. CBR assumes that community knowledge can be captured
in the form of stories (cases) so that the community members learn and solve problems by applying the lessons preserved in
the stories to the current situation. The process and results of formative evaluation following the concept of participatory
design are reported to set the context for further research and development. 相似文献
