The purpose of the study was twofold: to understand how usability affected physicians' performance as they used an electronic health record (EHR) and to ascertain whether use of a semantic search feature would better support physician performance during an information‐seeking task. Participants (n = 10) were asked to complete two search tasks to find pertinent patient information. In the first task, participants located the information as they normally would (through browsing the EHR). In the second task, participants employed a semantic search tool. Upon task completion, participants were interviewed to further understand their perceptions and information‐seeking behavior in an EHR. Statistically significant results confirmed that participants were able to more efficiently navigate through an EHR in terms of time and number of clicks when using the semantic search feature. Moreover, participants were more confident in the accuracy of their answers when using semantic search compared with the browsing method. Implications for practice are discussed. 相似文献

This paper reports a study into the role of a supporting adult in promoting effective learning relating to aspects of 3D shape in young children. Nursery and reception aged children carried out problem solving tasks using wooden blocks, in this case Poleidoblocs, embedded within playful contexts. Using the notion of 'scaffolding' and working within the child's Zone of Proximal Development, this study analyses the structured adult intervention that increases the effectiveness of learning and leads to an enhanced development of secure and transferable concepts. 相似文献

Online shared spaces are destinations where people of common interests interact to achieve common goals or borrow each other's expertise for personal pursuits. Due to a multitude of users, such spaces generate large amounts of content, thus creating a potential for information overload. To deal with it, users of online shared spaces develop information management strategies that frequently involve the use of information technology. In this paper we present a case study of the use of widgets as information management tools in uCern, an online shared workspace where healthcare industry stakeholders get involved in various types of interactions. To understand how widgets served the purpose of information management and whether they were considered useful, we administered an online questionnaire (n = 183) followed by qualitative interviews (n = 5). Data analysis revealed that study participants used widgets as tools that promoted their situation and activity awareness of events and activities going on in uCern and helped them with organizing and accessing the content in a quick and efficient manner. We also describe issues associated with the use of widgets and their usefulness as reported by participants and propose implications for design and development of online shared spaces in relation to information management tools. 相似文献
