Measuring perceived social presence in distributed learning groups   总被引:1,自引:0,他引:1  
Social presence—the degree to which ‘the other’ in a communication appears to be a ‘real’ person—has captured the attention of those dealing with learning in groups through computer-supported collaborative learning environments. The concept is important because it affects participation and social interaction, both necessary for effective collaboration and knowledge construction. This article reports on the construction and validation of a self-reporting (Dutch-language) Social Presence Scale to determine perceived social presence in distributed learning groups using computer-supported collaborative learning environments. The result is a one-dimensional scale consisting of five items with an internal consistency of .81. We used a nomological network of similar constructs for further validation. The findings suggest that the Social Presence Scale has potential to be useful as a measure for social presence.  相似文献

Being active in civic organizations can be expressed in multifarious forms of participation and commitment. With regard to individuals, the learning context it provides fosters personal development, sympathy for other perspectives, and social competencies in general and is, thus, particularly meaningful for young people in their second and third decades. With regard to organizations, civic participation strengthens the integration and dynamic adaptation of institutions to changing environments and, on a macro-level, raises social cohesion. The contexts of participation are various: not only in educational institutions and the world of work, but also in clubs, organizations and less formal groups, which are involved in social and political issues. Socio-structural and motivational factors, but also belonging to social networks determine the involvement in such forms of civic participation. Additionally, there is evidence of a mutual reinforcement of participation in different contexts. This is shown by the results of the DJI-Survey AID:A 2009.  相似文献

In two studies, we compared young children's performance on three variations of a nonverbally presented calculation task. The experimental tasks used the same nonverbal mode of presentation but were varied according to response type: (1) putting out disks (nonverbal production); (2) choosing the correct number of disks from a multiple-choice array (nonverbal recognition); and (3) giving a number word (verbal production). The verbal production task required children to map numerosities onto the conventional number system while the nonverbal production and nonverbal recognition tasks did not. Study 1 showed that the performance of 3-, 4- and 5-year-old middle-income children (N = 72) did not vary with the type of response required. Children's answers to nonverbally presented addition and subtraction problems were available in both verbal and nonverbal forms. In contrast. Study 2 showed that low-income children (3- and 4-year-olds; N = 48) performed significantly better on both nonverbal response type tasks than on the verbal response type task. Analysis of individual data indicated that a number of the low-income children were successful on the completely nonverbal calculation tasks, even though they had difficulty with verbal counting (i.e., set enumeration and cardinality). The findings suggest that the ability to calculate does not depend on mastery of conventional symbols of arithmetic.  相似文献

The present study was designed to investigate the relationships between role strains following the transition to secondary school and academic achievement. Academic engagement was hypothesized to mediate between role strain and achievement. The sample consisted of 749 students in their first year of secondary school. Four types of role strain were investigated: parent, teacher, school and peer. Parent and teacher role strains appeared to be negatively associated with academic achievement, as mediated through academic engagement. Parent and school role strain were directly and negatively associated with achievement. Results are discussed in the light of parenting practices and the developmental mismatch hypothesis.  相似文献

ABSTRACT

This article discusses issues concerning the spread of data-driven educational technologies in Brazil. Here, as elsewhere, educational technology continues to be promoted optimistically as the bearer of a panacea for historically-rooted social problems. Whilst some of these technologies have indeed contributed to important widening-participation programmes in the last two decades, widespread advocacy of technological ‘solutionism’, reflected in gradually stronger policy demands for efficiencies to be improved through ‘innovation’, has supported a relentless marketisation of the country’s educational systems. As transnational corporations position themselves to take control of key areas of these systems, threatening to restructure the whole sector, data-driven educational technologies provide the latest example in a series of ‘new’ ideas offered in an ever-expanding market. Based on the notion of ‘conceptual metaphors’, which encapsulate specific ways of perceiving, thinking and relating with the world, this article examines key metaphors underpinning discourses surrounding data-driven educational technologies in Brazil. In particular, the article analyses ways in which these specific metaphors may be promoting perspectives that ignore difference and obscure broader questions concerning education, thus contributing to the reproduction of previously existing problems and supporting new forms of colonisation.  相似文献

Objective: To analyze the association between attitudes of filial responsibility and adult child caregivers’ behaviors in the Southern Region of Brazil.

Methods: Cross-sectional study with 100 child caregivers of older adults. The data were collected through an interview using the protocol of filial responsibility adapted and validated to Brazilian Portuguese. Filial Expectation and Filial Piety scales evaluated the attitudes of filial responsibility. Caring behaviors assessed were: instrumental support, emotional, financial support, and companionship. The variables that presented p< .20 value in the bivariate analysis were inserted into a multivariate Poisson regression model.

Results: Financial and emotional support behaviors were significantly associated with filial piety (p = .050 and p = .001, respectively) and filial expectation (p = .013 and p = .023, respectively). Providing companionship was associated with filial piety (p = .015).

Conclusion: Attitudes of filial responsibility are associated with some but not all caregiving behaviors. Brazilians caring for older parents show more similarities to Chinese than to Canadian caregivers. Furthermore, filial responsibility and caregiving behaviors are strongly affected by Brazilian social and cultural norms. Reasons are discussed.  相似文献

There has been increasing recognition for the need to reform doctoral training practices to foster students’ personal epistemology. This study describes the design and evaluation of a learning experience designed to help students understand the scholarly publication process. Firstly, this study discusses the design of the learning experience, describing the collaborative process of writing an interdisciplinary publication using both online and face-to-face learning. Secondly, this study evaluates the effectiveness of the learning experience by examining students’ reflections. We show that participation in the learning experience helped students to develop their academic writing proficiency, collaboration and teamwork, intercultural competence, and ability to engage in reflective practice. Importantly, we show that each student also created more individualised knowledge, gaining insight into how they and others think. This study, therefore, demonstrates that personal epistemology can be fostered through collaboration in a doctoral writing group context.  相似文献
