Effective knowledge sharing underpins the day-to-day work activities in knowledge-intensive organizational environments. This paper integrates key concepts from the literature towards a model to explain effective knowledge sharing in such environments. It is proposed that the effectiveness of knowledge sharing is determined by the maturity of informal and formal social networks and a shared information and knowledge-based artefact network (AN) in a particular work context. It is further proposed that facilitating mechanisms within the social and ANs, and mechanisms that link these networks, affect the overall efficiency of knowledge sharing in complex environments. Three case studies are used to illustrate the model, highlighting typical knowledge-sharing problems that result when certain model elements are absent or insufficient in a particular environment. The model is discussed in terms of diagnosing knowledge-sharing problems, organizational knowledge strategy, and the role of information and communication technology in knowledge sharing. 相似文献

Effects of Different Instructional Approaches on Young Children's Achievement and Motivation 总被引：3，自引：0，他引：3
Children in child-centered preschools and kindergartens were compared to children in didactic, highly academic programs in terms of their basic skills achievement and a set of motivation variables. The study included 227 poor, minority, and middle-class children between the ages of 4 and 6 years. Children in didactic programs that stressed basic skills had significantly higher scores on a letters/reading achievement test but not on a numbers achievement test. Being enrolled in a didactic early childhood education program was associated with relatively negative outcomes on most of the motivation measures. Compared to children in child-centered programs, children in didactic programs rated their abilities significantly lower, had lower expectations for success on academic tasks, showed more dependency on adults for permission and approval, evidenced less pride in their accomplishments, and claimed to worry more about school. Program effects were the same for economically disadvantaged and middle-class children, and for preschoolers and kindergartners. 相似文献

This phenomenological study, based on ecological systems theory, examined the college student bereavement experience in a Christian university. Undergraduate students (N = 127) from a small Christian university provided answers to open‐ended questions about their experiences regarding college following a death loss. Results indicate that students are generally successful in adapting to bereavement and prefer an environment open to discussing death and asking difficult religious questions. Implications for counselors are provided. 相似文献

AbstractThe literature on improving student engagement with assessment and feedback has a tendency to treat all students as if they are the same. Students with lower levels of attainment are generally under-represented within empirical studies and their feedback behaviours are less well understood. The recent drive to improve student assessment and feedback literacy and the move from ‘feedback’ being information about a task to being a process of understanding and using performance information is a larger conceptual leap for some students than others. In this paper, we consider issues surrounding the transition to new modes of feedback, focussing on what is needed for those who find study difficult and persistently are disappointed by their levels of attainment, to benefit from and take advantage of our feedback pedagogies. We examine literature advocating strategies such as increasing agency, using praise, developing feedback literacy and cultivating a growth mind-set. We argue that students who underachieve may benefit from strong relationships with educators and peers, exposure to feedback rich, low stakes environments, which permit repeated integrations of practice and feedback, and building feedback literacy through peer assessment activities. 相似文献

Since the inception of the My Favorite Murder podcast in January 2016, cohosts Karen Kilgariff and Georgia Hardstark have built an empowered fanbase that tunes in weekly to hear a true-crime/comedy mashup. The present study analyzed what draws MFM listeners with a mental illness diagnosis to the podcast and how they utilize related social media platforms to connect with others by employing both a uses and gratifications paradigm and concepts from the audience involvement literature. An online survey of users of the MFM Facebook group (N = 541) was conducted and the results are discussed. 相似文献

The purpose of this study was to investigate the relationship between the contributions students make to the problem-based tutorial group process as observed by their peers, self-study time and achievement. To that end, the Maastricht Peer Activity Rating Scale was administered to students participating in Problem-Based Learning tutorial groups. With this rating scale students had to rate the constructive, collaborative and motivational activities of their peers within the tutorial group. In addition, time spent on self-study was measured with a self-estimation method and achievement was measured with a unit test and a group assignment. A causal model of these variables was developed, in which the three types of activities were assumed to affect time spent on self-study, which would in turn affect unit test scores and group assignment scores. A structural equation modeling analysis indicated acceptable model fit. Especially apparent was the evidence for the causal relations between a student’s constructive activities and his/her unit test score and between a student’s collaborative activities and the group assignment score. On the other hand, time spent on self-study was not affected by the students’ contributions, nor did it have an effect on the unit test score. These results suggest that there are indeed causal relations between a student’s contributions to the tutorial group process and achievement. 相似文献
