For educational software to take advantage of contemporary views of learning, instructional designers need to employ design models that incorporate the variety of ideas that are based on constructivist frameworks for developing learning environments. These environments, if well designed, can support learner construction of knowledge, however, such frameworks are based upon arguments that learners should be placed in authentic environments that incorporate sophisticated representations of context through such constructs as “virtual worlds”. Within these environments the learner is supported by visual metaphors constructed to represent the information structure and how the “world” operates. This paper will discuss the framework employed in the development of several virtual solutions and the process by which they were constructed.  相似文献

兵荒马乱的概念,对和平时代的人来说,因为不曾经历过,有时也是一种不小的诱惑。正如不曾触网的人,对于.com的起起伏伏,总会有些未经体验的遗憾。仅凭这一点,已足以让胡一郎感到自豪,而图佑公司一周来的动荡,所展现出来的东西,更让胡一郎觉得是难得的经历。 最先离开的是市场部的Tom,人大在读的MBA,因为没有多少工作经验,又是初进Internet行业,所以在市场部里,也就是一打杂的材料。想不到的是,这小子离开图佑,摇身一变,就成了一家专业网站的BD经理,位置高了,薪水涨了,走的时候摆出一副得道升天的姿态,对图佑一脸的看不上。难免让人产生心理上的不平衡,也让胡一郎对做BD看得更轻了。 黯然离开的是老赵,这个过了而立之年的报社老编,在公司里一直扮演着忠厚的老大形象,自称一不留神掉进了.com,也意料不到地发现了年轻的快乐。离开图佑,  相似文献

With the development of new media, the issue of privacy and its determinants has become the subject of a large body of literature in recent years. The main objective of this study was to check whether loneliness is a predictor of putting private information on Facebook. The participants were 887 young people. Facebook Privacy Scale and Loneliness Scale were used. We showed that young age and loneliness are predictors of disclosure on Facebook. Moreover, junior high school students more often put private information on their Facebook profiles than senior high school and university students.  相似文献

Organizations have recognized the revenue potential for social commerce (purchasing products via social networks), but such transactions only comprise a small percentage of revenue. Companies have yet to determine the factors that contribute to social commerce failure. In social networking, trust is established when two parties have a history of trustworthy interactions. Acknowledging that social commerce represents a fundamentally different purchasing environment than typical business transactions, we examine the role of trust in determining consumers’ decisions to engage in social commerce for their purchases. We apply trust transfer theory to the social commerce context to assess whether trust in known entities can be transferred to business transactions facilitated through a social network with unknown parties. Using a field survey, we found that trust in the Internet and trust in firms significantly influence consumers’ trust and ultimately their intention to engage in social commerce. Implications for research and practice are discussed.  相似文献

The paper presents an empirical study of user involvement in developing a technical standard for a scientific community's information system project. The case illustrates how multiple perspectives are involved when considering the user role in practice. The case presents a situation where both developers and users were pre‐defined in the design and development phases of the standard as homogeneous groups of actors. Groups of actors changed to become more heterogeneous and ‘fluid’ in the deployment and implementation phases, thus forming ‘webs of developers’ and ‘webs of users’. Detailed analysis of the process in its entirety shows the blurredness of boundaries between ‘developer’ and ‘user’ categories and roles, and reveals challenges at social and organizational levels. Three models pertaining to the system development process are presented in order to illuminate differing perspectives on the user and on the development process itself. The paper draws theoretically from information systems, social informatics, and science and technology studies. The research contributes to a deeper, interdisciplinary understanding of ‘the’ user, of multiple roles in systems development, and of dynamic sets of user–developer relations.  相似文献

There is a recognized disconnect between testing research and industry practice, and more studies are needed on understanding how testing is conducted in real-world circumstances instead of demonstrating the superiority of specific methods. Recent literature indicates that testing is a cross-cutting activity that involves various organizational roles rather than the sole involvement of specialized testers. This research empirically investigates how testing involves employees in varying organizational roles in software product companies. We studied the organization and values of testing using an exploratory case study methodology through interviews, defect database analysis, workshops, analyses of documentation, and informal communications at three software product companies. We analyzed which employee groups test software in the case companies, and how many defects they find. Two companies organized testing as a team effort, and one company had a specialized testing group because of its different development model. We found evidence that testing was not an action conducted only by testing specialists. Testing by individuals with customer contact and domain expertise was an important validation method. We discovered that defects found by developers had the highest fix rates while those revealed by specialized testers had the lowest. The defect importance was susceptible to organizational competition of resources (i.e., overvaluing defects of reporter’s own products or projects). We conclude that it is important to understand the diversity of individuals participating in software testing and the relevance of validation from the end users’ viewpoint. Future research is required to evaluate testing approaches for diverse organizational roles. Finally, to improve defect information, we suggest increasing automation in defect data collection.  相似文献

Who Are You? The Trade-Off between Information Utility and Privacy   总被引:1,自引:0,他引:1  
There's no doubt that personal information can be valuable to companies. People are willing to give up information about themselves not because they're stupid or because they're being tricked by evil corporations, but because it can sometimes be in their best interests to do so. From this perspective, the important questions are how users can provide or limit access to that information, what benefits they might receive in exchange for a bit of information, and how they perceive the value of those benefits.  相似文献

This paper explores how borrowers’ financial and personal information, loan characteristics and lending models affect peer-to-peer (P2P) loan funding outcomes. Using a large sample of listings from one of the largest Chinese online P2P lending platforms, we find that those borrowers earning a higher income or who own a car are more likely to receive a loan, pay lower interest rates, and are less likely to default. The credit grade assigned by the lending platform may not represent the creditworthiness of potential borrowers. We also find that the unique offline process in the Chinese P2P online lending platform exerts significant influence on the lending decision. We discuss the implications of our results for the design of big data-based lending markets.  相似文献

Many problems in paleontology reduce to finding those features that best discriminate among a set of classes. A clear example is the classification of new specimens. However, these classifications are generally challenging because the number of discriminant features and the number of samples are limited. This has been the fate of LB1, a new specimen found in the Liang Bua Cave of Flores. Several authors have attributed LB1 to a new species of Homo, H. floresiensis. According to this hypothesis, LB1 is either a member of the early Homo group or a descendent of an ancestor of the Asian H. erectus. Detractors have put forward an alternate hypothesis, which stipulates that LB1 is in fact a microcephalic modern human. In this paper, we show how we can employ a new Bayes optimal discriminant feature extraction technique to help resolve this type of issues. In this process, we present three types of experiments. First, we use this Bayes optimal discriminant technique to develop a model of morphological (shape) evolution from Australopiths to H. sapiens. LB1 fits perfectly in this model as a member of the early Homo group. Second, we build a classifier based on the available cranial and mandibular data appropriately normalized for size and volume. Again, LB1 is most similar to early Homo. Third, we build a brain endocast classifier to show that LB1 is not within the normal range of variation in H. sapiens. These results combined support the hypothesis of a very early shared ancestor for LB1 and H. erectus, and illustrate how discriminant analysis approaches can be successfully used to help classify newly discovered specimens.  相似文献

Student groups completed a rank-ordering task in a "low-structure" computerized meeting room where all group members had equal access to a shared computer with a large monitor. Strategies used by the groups to distribute control over the public monitor, determinants of which members took control, and the consequences of control strategies were examined. Groups adopted either a dedicated-scribe strategy, in which one member had control throughout the session, or a non-dedicated-scribe strategy, in which control of the public monitor passed among members. Groups with at least one member who had low proficiency with the technology were very likely to adopt a dedicated-scribe strategy. Social influence within the group, proficiency with the computer system, and gender predicted which group members would take control of the public monitor. The results suggest that a group's social structure may be altered by the use of low-structure computer support, depending on the distribution of technical proficiency in the group. Dedicated-scribe groups had marginally better task performance but reported less increase in satisfaction (over previous work together) than non-dedicated-scribe groups. The implications of this research for the design and use of group computer support are discussed.  相似文献

Surveys and opinion polls are extremely popular in the media, especially in the months preceding a general election. However, the available tools for analyzing poll results often require specialized training. Hence, data analysis remains out of reach for many casual computer users. Moreover, the visualizations used to communicate the results of surveys are typically limited to traditional statistical graphics like bar graphs and pie charts, both of which are fundamentally noninteractive. We present a simple interactive visualization that allows users to construct queries on large tabular data sets, and view the results in real time. The results of two separate user studies suggest that our interface lowers the learning curve for naive users, while still providing enough analytical power to discover interesting correlations in the data.  相似文献
