The purpose of this review, spanning over 12 years of publication of Distances et Médiations des Savoirs (DMS), formerly Distance et Savoirs (DMS) (2003–2014), is guided by the question why and how French-speaking researchers addressed the issues of time, workload and costs in distance learning, and how this was affected by the increasing influence of information and communication technologies.  相似文献

Purpose: Changing research design and methodologies regarding how researchers articulate with end-users of technology is an important consideration in developing sustainable agricultural practices. This paper analyzes a joint experiment as a multi-stakeholder process and contributes to understand how the way of organizing social learning affects stakeholders’ ownership of process outcomes. Design/Methodology/Approach:A learning group composed of the different stakeholders of the oil palm seed system in Benin was set around a joint experiment. We use a detailed account of the group dynamics to understand the social process. Findings: The way the process is designed and conducted has a great effect on the ownership by the participants. Methodological steps taken in this research process showed its efficacy to produce quick and positive feedback mechanisms. Stakeholders’ perspectives on what constitutes a quality oil palm seedling varied widely. Participants, mainly nursery holders, learned new production practices. Representatives of the research center learned a mismatch of recommendations with users’ contexts. Field observations further to the process indicate changes in practices among stakeholders that would be sustainable. Practical Implications: Beyond focusing on outcomes, initiatives in multi-stakeholder processes should also document and analyze social processes in order to better understand the mechanisms by which such processes foster socio-technical change, as well as identify potential institutional barriers to such processes. Originality/Value: Through a detailed analysis of group dynamics, this paper addresses an important knowledge gap in participatory agricultural development.  相似文献

Students more and more have access to online recordings of the lectures they attend at universities. The volume and length of these recorded lectures however make them difficult to navigate. Research shows that students primarily watch the recorded lectures while preparing for their exams. They do watch the full recorded lectures, but review only the parts that are relevant to them. While doing so, they often lack the required mechanisms to locate efficiently those parts of the recorded lecture that they want to view. In this paper, we describe an experiment where expert tagging is used as a means to facilitate the students' search. In the experiment, 255 students had the option to use tags to navigate 18 recorded lectures. We used the data tracked by the lecture capture system to analyze the use of the tags by the students. We compared these data to students who did not use the tagging interface (TI). Results show that the use of the TI increases in time. Students use the TI more actively over time while reducing the amount of video that they view. The experiment also shows that students who use the TI score higher grades when compared with students who use the regular interface.  相似文献

Adolescence is marked by the development of personal identity and is associated with structural and functional changes in brain regions associated with Self processing. Yet, little is known about the neural correlates of self‐reference processing and self‐reference effect in adolescents. This functional magnetic resonance imaging study consists of a self‐reference paradigm followed by a recognition test proposed to 30 healthy adolescents aged 13–18 years old. Results showed that the rostral anterior cingulate cortex is specifically involved in self‐reference processing and that this specialization develops gradually from 13 to 18 years old. The self‐reference effect is associated with increased brain activation changes during encoding, suggesting that the beneficial effect of Self on memory may occur at encoding of self‐referential information, rather than at retrieval.  相似文献

The globalized economy remains deeply rooted in historically shaped territories, in opposition to the common-place image of a footloose economy of flows. Regions provide the market economy with immaterial resources essential to its development. This is strongly reinforced, in my opinion, by a range of complex effects primarly linked to the change in competition patterns in global markets. Firms are driven to adopt quality - and innovation-based strategies, and still are obliged to reduce costs. Traditional, rigidly fragmented, Taylorist production organization, highly efficient in a stable price-based competition environment, is becoming counterproductive in this new context. The competitivness of companies lies no longer in the mere intensification of work and traditional productivity effects. It results mainly from the density and the relevance of co-operation established between the different actors in a value chain. And this co-operation cannot be set up - this is the point I wish to emphasize - either by the decisionmaking of a more or less centralized technostructure or through sheer market forces. The ability to promote inter-firm co-operation and confidence, to share values and anticipations, the convergence of projects, the relevance of institutionnal frames and finally the quality of local public and private governance are the key factors of success, instead of traditional geographic location factors, more or less neutralized by the decrease of communication costs. In other words, the key resources for development are socially and politically built up,and not a given of nature, as in the past. Potentially, all regions and cities, whatever their size, stand to benefit from this.  相似文献

The purpose of this study was to identify the different subgroups of students at risk of dropping out of school. The typology was developed based on the three main contexts associated with school dropout risk, namely, the personal, family and school contexts. On the basis of these factors, the clustering results enabled us to categorize at-risk students into four subgroups: (1) the Anti-Social Covert behavior type, (2) the Uninterested in school type, (3) the School and Social Adjustment Difficulties type, and (4) the Depressive type. Moreover, considering all the contexts involved in school dropout, the clustering technique confirms the importance of behavior problems and learning difficulties, while emphasizing the significance of both depression and the family and classroom environments in the development of dropout risk. Students at risk of dropping out of school report many family organisational problems and that they obtain little emotional support from their parents. They also perceive little order or organisation in the classroom.  相似文献

The postsecondary education and work status of 46 rubella deaf young adults was described and evaluated as an outcome of ethnicity, socioeconomic status, preschool attendance, early parent involvement, and degree of prior mainstreaming. With regard to postsecondary education attendance, 24 had two or more years, 11 had one year or less, and 11 had none. At time of interview, 19 were still attending school, 22 were working and five were neither working nor attending an educational program. Ethnic minority young adults were underrepresented in the group with two or more years of postsecondary education, and overrepresented in the group neither working nor in school at time of interview. Prior mainstreaming was a determinant of postsecondary education attendance over and above the effects of demographic and background characteristics. Implications of these findings are discussed.  相似文献
