Online instructional design is a relatively new field for librarians. Many librarians have taken on the challenge of creating online library tutorials without the benefit of formal education and training in the field. Librarians can learn much from research in system design, human–computer interaction, and applied psychology, as it relates to the creation of online learning systems. Researchers in these areas believe that people approach online learning systems by making use of a conceptual—or mental—model of the system. Designers' mental models influence the way they create learning systems; students' mental models affect the way they interact with and learn from the system. This article compares and contrasts the mental models of librarians and students as they relate to online library tutorials. These mental models are examined through a review of existing library tutorials, usability studies on various library tutorials, and student interviews about the research and writing process. Analysis of these models demonstrates how undergraduates' mental models vary, often significantly, from the mental models of the librarians who design the online library tutorials. Interpretations of this analysis identify ways in which to design a tutorial for more effective instruction aimed at the undergraduate. 相似文献

Contemporary scientific publishing in mathematics and physics (as in other exact sciences) is a complex and rapidly changing process. The most important element of this process, namely, the refereeing process is considered. In particular, meaningful changes towards refereeing process in mathematics and physics are identified and predicted. Considering a transition that takes place from the traditional refereeing system to other models and introducing the four basic parameters of the refereeing process, namely, the review stage, the openness for editors, referees and authors, journals and e-journals, feedback and e-feedback, several different models are proposed and described for improving the traditional refereeing system (e.g., 2-stage open and semi-open pre-review models, 1-stage open and blind pre-review models, and 0-stage open post-review models). 相似文献

This study investigated the dynamic process of people constructing mental models of MedlinePlus, a medical information web space, during their interaction with the system. Thirty-eight participants participated in the study. Their mental models of MedlinePlus were measured by a concept listing protocol and an interview method at three time points: after they freely explored the system for 5 min (T1), after the first search session (T2), and after the second search session (T3). The analysis revealed that participants constructed their mental models of MedlinePlus based on the schemas that they have of information-rich web spaces. The model construction process involved changes and development in three parallel dimensions: cognition, emotion, and behavior. The development is enabled and coordinated by three mental activities: assimilating new concepts, modifying existing concepts, and phasing out previously perceived concepts. Furthermore, mental model construction is not only a function of users' internal cognition, but also affected by external cognitive structures, including the system, system feedback, and tasks. Mental model construction is also a process distributed over time. The results suggested that mental models could serve as a framework for guiding user research and system design. The dynamic nature of the mental models indicated that an iterative approach needs to be adopted. 相似文献

如今,战略性新兴产业已经提升到国家战略地位。从产业层面上来看,因为产业信息资源是企业层面信息资源的集合,所以产业层面的信息需求具有更多的共性。本文通过厘清战略性新兴产业共性化信息需求块资源模型、机理结构模型和三维驱动模型,来分析战略性新兴产业共性化信息需求机理。文章提出了产品数据信息、运营数据信息、用户需求数据信息和品牌数据信息块资源模型。在其结构关系中,产业和企业的持续发展,最基本的结构元素是"产品"。因此,以产品为核心的信息需求则成为结构机理的核心要素。在驱动关系中,用户需求驱动、效益驱动和网络结构凝聚驱动三维驱动模型驱动着信息需求在产业-企业-产品-用户的结构模型中服务于产品。基于所提出的模型,本文以战略性新兴产业专业知识服务系统为例,为系统完善提出未来发展的建议,旨在为我国战略性新兴产业相关信息资源服务平台提供依据和参考,进而推动战略性新兴产业的运行与发展。 相似文献

Decision support systems (DSS) are a class of information systems where data, models, and an interface are combined to support a decision-maker's needs for data and analysis. This article reports on a system which fits all of the classic definitions of a DSS and which includes spatial models of object locations as crucial parts of the analytic, data, and interface support provided to the user. The system illustrates several interesting aspects of the construction of systems of this type, including the potential role of geographic information system (GIS) capabilities in DSS; the translation of user decision support needs with a geographic component into a DSS architecture; and the integration of a PC-based GIS package with additional interface, data management, and analytic tools. The system also illustrates certain managerial implications for systems of this type, including the importance of planning for system maintenance and the value of geographic data. 相似文献
