The experience of meaning in a learning situation is a stated goal of Knowledge Promotion Reform in Norway. This study, guided by self-determination theory, examines how pursuing intrinsic and extrinsic life goals relates to the experience of meaning in vocational education. The study also examines how learning support, perceived competence, and different types of autonomous motivation are associated with students' experiences of meaning. The sample consisted of health and social care students (N?=?405) in upper secondary school. The results indicated that intrinsic goals encouraged meaningfulness in all subjects, whereas extrinsic goals related to perceived meaninglessness in vocational subjects. Learning support, perceived competence, and autonomous types of motivation all have a positive link to students' experiences of meaning, either directly or indirectly. 相似文献

In this text we compare children’s expressions in drawings to their statements during interviews, for the purpose of understanding how different situations afford children to make meaning. In specific we study how two different activities interact and afford children to make meaning differently about the human body. The analytic attention is drawn to the meaning-making the children made as they in pairs were asked to explain the body drawings that they did prior to the interviews. Meaning-making was studied by using a practical epistemology analysis, an analysis facilitating understanding of how relations are established in a developing conversation, and more generally providing understanding from a child perspective. The results indicate that several reasons are at hand for children in the two different situations; namely, social, artistic, practical, empirical and memory reasons are identified. Social reasons refer to statements belonging to the social context and items that were described as inappropriate to express. Artistic reasons were interpreted from aesthetic judgements, referring to the artistic quality of the drawing. Practical reasons were given in situations where children expressed, for example, that the space limited their opportunities to draw. Empirical reasons are built on children’s statements referring to picture items that are identified by pointing or touching their own body. Memory reasons are involved in all the situations where children explained items were previously omitted, because the body part had been temporarily forgotten. Furthermore, we suggest that children interpret situational aspects and make judgements concerning the relevance of their different reasons. By these means we hope to facilitate children’s understanding of interview questions and also to improve researchers’ understanding of children’s ability to grasp relevant details prior to their response (or participation). 相似文献

Success of the expatriate spouse has been repeatedly identified as a key to overall expatriate assignment success. However, little is known about how to increase the expatriate spouses’ adjustment to an overseas assignment. This study examines this problem from an occupational health viewpoint, looking at the relationships of stress with various outcomes related to success: satisfaction, adjustment, and well-being. In addition, the current study tests the effects of social support and a new construct, Ibasho, briefly defined as a sense of comfort and psychological security that a person feels in specific locations they regularly visit, as moderators of stressor–outcome relationships. Results suggest that stress is highly related to all outcomes measured. In addition, initial support for the independence and importance of the construct of Ibasho is established. Ibasho showed significant bivariate relationships with all of the measured variables. In addition, Ibasho accounted for unique variance in the prediction of general adjustment, personal adjustment, satisfaction, and depression above and beyond demographic control variables and social support. Finally, Ibasho interacted with stressors in order to significantly predict perceived stress. 相似文献

The article is based on a research and development work project (R&D project) conducted in a Norwegian lower secondary school. The purpose of the text is to describe the researchers’ and teachers’ roles during the initial phase of such a project, and what this phase and the close cooperation between the researcher and teachers mean for the progress of the project. The reader will see how the participating teachers modify their attitudes to the project throughout the start-up phase. This phase is outlined by means of empirical data. The study shows how such a project challenges the researchers’ communicative, social and knowledge competence. Furthermore, teachers have to see the need for development and willingly participate in developmental processes, listening to and using researchers as resource persons, if a start-up phase is to be successful for subsequent development in the project. 相似文献

The blood-brain barrier (BBB) is a critical structure that serves as the gatekeeper between the central nervous system and the rest of the body. It is the responsibility of the BBB to facilitate the entry of required nutrients into the brain and to exclude potentially harmful compounds; however, this complex structure has remained difficult to model faithfully in vitro. Accurate in vitro models are necessary for understanding how the BBB forms and functions, as well as for evaluating drug and toxin penetration across the barrier. Many previous models have failed to support all the cell types involved in the BBB formation and/or lacked the flow-created shear forces needed for mature tight junction formation. To address these issues and to help establish a more faithful in vitro model of the BBB, we have designed and fabricated a microfluidic device that is comprised of both a vascular chamber and a brain chamber separated by a porous membrane. This design allows for cell-to-cell communication between endothelial cells, astrocytes, and pericytes and independent perfusion of both compartments separated by the membrane. This NeuroVascular Unit (NVU) represents approximately one-millionth of the human brain, and hence, has sufficient cell mass to support a breadth of analytical measurements. The NVU has been validated with both fluorescein isothiocyanate (FITC)-dextran diffusion and transendothelial electrical resistance. The NVU has enabled in vitro modeling of the BBB using all human cell types and sampling effluent from both sides of the barrier. 相似文献
