This article describes the pedagogical framework of an interdisciplinary and international project entitled NINTER (Networked Interaction: Theory-Based Cases in Teaching and Learning). The practical aim of the project is to produce a pedagogical model for learning and teaching in networked environments. The research project has its foundation on socio-constructivist learning theories, with one of the most important principles being the idea of apprenticeship in thinking. The article also takes a look at the first results obtained from different kinds of videotaped and written material that were collected during a WWW-based university course. Also questions raised from the data for future research are considered. 相似文献

The need to preserve cultural heritage on paper requires the setting up of methods and treatments that can be applied to original documents. The cellulose main degradation processes are hydrolysis and oxidation. Only the first one has been widely investigated. The Istituto Centrale per la Patologia del Libro (ICPL) focused its attention on oxidation phenomena and studied a particular class of reducing agents, namely the borane-amine complexes. During the investigation it was found that the borane tert-butylamine complex, besides being the most promising reducing agent, was also able to react with carboxylic functions. In the present study 1H and 13C NMR, Pulsed field gradient NMR spectroscopy as well as Raman spectroscopy were used as analytical tools to disclose the mechanism of the interaction between the borane tert-butylamine complex and the carboxylic functions. Given the complexity of the paper/environment interactions and the subsequent degradation phenomena, we worked on simplified models based on small carbohydrate molecules in order to reproduce the behavior of degraded paper after reductive restoration. Modified D-glucose and D-cellobiose were used in this first step in order to set up the analytical methods before approaching more complex systems such as microcrystalline cellulose and paper. Our results give the experimental evidence that borane tert-butylamine complex is also able to neutralize acidic functions. This finding has important perspectives in paper restoration. 相似文献

Word-of-mouth (WOM) can be a powerful, persuasive source of information, but relatively little is understood about how consumers utilize information in service evaluations and how the source of WOM (e.g. friends, family) affects attitudes. The importance of WOM is acknowledged in the services context; however, the research field of higher education has found some inconsistent results concerning the impact of WOM. The aim of this study, with its focus on information processing, is to enhance the understanding of these varying results with data from international master's degree applicants. By means of structural equation modeling, the results suggest that the processing of WOM differs depending on the source and the difficulty of evaluation criteria. Information through some sources of WOM is mainly cognitively processed, whereas in others information is processed more as simple cues. Overall, insights are provided into the impact of WOM, and higher education marketing. 相似文献

Empirical research reveals that students face difficulties engaging in learning and achieving their goals in a variety of learning contexts. To study effectively, students need to regulate their learning process. In spite of increased understanding of cognitive aspects of self-regulation, motivational aspects of regulation have not yet been thoroughly probed. This study investigates how motivation is connected to self-regulated learning when elementary school students (N = 32) study science in real classroom contexts using gStudy software. This was done by: (1) identifying students' situated motivation during the learning process, (2) analyzing how the students with different motivational approaches activated cognitive self-regulation in authentic learning situations across multiple learning episodes, and (3) complementing the understanding with the students' individual accounts of their motivation regulation during the learning process. The results show that there are qualitative differences in the self-regulation tactics used by the high- and low-motivation students as they study. Motivation is linked closely to active self-regulation. 相似文献

Previous research has shown that observing peers' success in learning is important for the development of children's belief in themselves as learners. However, in research, these observations are seldom made in actual classroom learning activities. This study investigated how children explain factors that lead to their peers' successes in classroom learning activities. Seventeen elementary school children from first, second and third grade participated in a ‘detective course’ in which they needed to capture moments of success using a mobile camera device. The pictures were used for photo-elicitation interviews (n?=?28) in order to find out children's views on the reasons for their peers' successes in learning situations. Pictorial data (n?=?361) were coded with data-driven categories to see what kind of situations children considered successful. The results show that the reasons given for peers' successes dealt with situation-specific information, such as mastery and quality of performance. Findings indicate that children explain peers' successes through the actions that their peers made during the situations, rather than by comparison between the abilities of their classmates. The results provide information for practitioners and teachers on how to promote children to use the example of their peers to recognise and explain successful learning situations in the classroom. 相似文献

The aim of this study was to investigate how finnish students explain factors that contribute to their achievement in classroom learning activities and whether these factors are related to support of self-regulated learning (SRL) in classroom. Over seven weeks, 24 primary school students were videotaped during their typical classroom activities in 28 lessons to capture moments when they succeeded in learning tasks. From the video observations, 62 episodes were edited and used in stimulated recall interviews in which students were asked to report the reasons they related to their achievement in learning situations. Data-driven content analysis was used to analyse the open-ended interview data. The video observation data were analysed and sorted into theory-driven categories in order to find out how SRL was supported in classrooms. The results showed that students describe achievement through the actions that they took in the learning situations, such as being able accomplish the task. The reasons given for their achievement dealt with ability to accomplish the tasks or doing academic activities in order to achieve in the task. Furthermore, the students recognised classroom activities that support SRL, acknowledging their contribution to their achievement, mostly through the support that they received from their teachers and peers. 相似文献

Young people labelled ‘disadvantaged’ or ‘at risk of social exclusion’ are increasingly directed into publicly funded or NGO-based, partly privately financed projects in order to secure their desired integration into society through work or further education. In this article, we carry out a comparative analysis of youth training programmes in Brazil and Finland based on empirical fieldwork undertaken in two separate research projects. The research data consist of qualitative interviews of the projects’ participants and management. The focus of the analysis is on youth employment projects as discursive practices, that is, on the ways that knowledge on employment and employment-related responsibilities is produced in the discourses and practices of the projects. Despite the different contexts, the analysis shows that the youth training projects share a number of commonalities with regards to the shaping of the self as entrepreneurial and self-regulated. This is linked to the global dominance of a new form of governance, which relies on and actively promotes the individualisation of responsibility and obscures the structural and societal forces that lie behind youth unemployment and exclusion. We suggest that engaging young people in critical discourses about the sources of inequality would be the key to more equitable forms of development. 相似文献

This study examined the role of motivational or attitudinal factors, such as achievement beliefs and behaviours, in learning to read before receiving formal instruction. A total of 200 Finnish children were examined at ages 5 and 6½. Half of them (n = 107) had a familial risk for dyslexia. The results showed that those children who were verbally skilful at age 5 showed a higher level of task-focused behaviour at age 6½. This task-focused behaviour then contributed to spontaneous reading acquisition. The impact of previous verbal skills on spontaneous reading acquisition was mediated in part by achievement behaviour. 相似文献

The editors of this special section have focused on a theme that is both old and new. Research on help seeking has a long history and a strong theory pointing out that help seeking is an important academic strategy of self-regulation that facilitates learning. It is a new topic to consider in the context of broadened learning environments, increased opportunities provided by technology and multiple forms of social interactions available in new learning environments. I’ll consider the special section from a self-regulated learning research perspective and focus my remarks on three themes: (a) “How does help seeking help?”, (b) “adaptiveness of strategic help seeking”, and (c) “help seeking in pairs and teams”. 相似文献
