The internet as a new distribution channel of scientific grey literature: The case of Italian WWW servers     

Daniela Luzi CNR-ISRDS 《Publishing Research Quarterly》1997,13(2):33-47

The enormous range of information sources and communication services available on the Internet today recalls the information explosion and information overload that characterizes this century. We are certainly facing new kinds of information and communication patterns, based on direct electronic communication between end-users among themselves and/or between end-users and information sources. Moreover, this new channel of communication provides the opportunity to distribute different types of information, which in some cases are available only in a networked environment. The aim of this article is to analyze whether this new scenario has stimulated the production and the direct distribution of grey literature as well as changing its “traditional” features. The starting point of the study are the Italian WWW servers of the National Research Council.  相似文献   

Training Theory of Mind and Executive Control: A Tool for Improving School Achievement?     

Daniela Kloo  Josef Perner 《Mind, Brain, and Education》2008,2(3):122-127

ABSTRACT— In the preschool years, there are marked improvements in theory of mind (ToM) and executive functions. And, children's competence in these two core cognitive domains is associated with their academic achievement. Therefore, training ToM and executive control could be a valuable tool for improving children's success in school. This article reviews several successful training studies in preschool children showing that these two school-related competencies can be trained. We also discuss methodological factors that may be important for the effectiveness of training programs. Finally, the review outlines implications of brain research for such training interventions.  相似文献

Perfect presence: What does this mean for the design of virtual learning environments?     

Denise Whitelock  Daniela Romano  Anne Jelfs  Paul Brna 《Education and Information Technologies》2000,5(4):277-289

One of the advantages of building a virtual reality system is that it allows students to enter new worlds which in these instances include trips to the bottom of the Atlantic Ocean, a field visit to an Oak Wood and a close encounter in a 3D maze. In all these environments the factors affecting a sense of being there or presence was investigated. Enhanced audio feedback increased a subjective sense of presence but did not increase students' conceptual learning scores. We have also found that a sense of social presence enhanced the notion of being there together with measures of collaboration. However being there can take its toll on students and our findings suggest it imposes a cognitive overload. Where students have a choice, they try and reduce this overload by asking for conceptual tools to assist them in their learning tasks. The studies reported in this paper provide some benchmark data about these issues which deserve further investigation if we are to design effective virtual environments for conceptual learning.  相似文献   

Girls and computer science: experiences,perceptions, and career aspirations     

Jung Won Hur  Carey E. Andrzejewski  Daniela Marghitu 《Computer Science Education》2017,27(2):100-120

The purpose of this mixed methods study was to examine ways to promote computer science (CS) among girls by exploring young women’s experiences and perceptions of CS as well as investigating factors affecting their career aspirations. American girls aged 10–16 participated in focus group interviews as well as pre-, post-, and follow-up surveys while attending a CS camp. The analysis of data revealed that although the participants were generally positive about the CS field, they had very limited knowledge of and experience with CS, leading to little aspiration to become computer scientists. The findings also indicated that girls’ affinity for and confidence in CS were critical factors affecting their motivation for pursuing a CS-related career. The study demonstrated that participation in the CS camp motivated a small number of participants to be interested in majoring in CS, but the activity time was too short to make a significant impact. Based on the findings, we suggest that providing CS programming experiences in K-12 classrooms is important in order to boost girls’ confidence and interest in CS.  相似文献   

Cross-cultural comparisons of child-reported emotional and physical abuse: rates, risk factors and psychosocial symptoms   总被引：1，自引：0，他引：1  

Sebre S  Sprugevica I  Novotni A  Bonevski D  Pakalniskiene V  Popescu D  Turchina T  Friedrich W  Lewis O 《Child abuse & neglect》2004,28(1):113-127

OBJECTIVES: This study was designed to assess the incidence of child emotional and physical abuse, associated risk factors and psychosocial symptoms in a cross-cultural comparison between post-communist bloc countries. Method: One-thousand one-hundred forty-five children ages 10-14 from Latvia (N = 297), Lithuania ( N = 300), Macedonia (N = 302), and Moldova (N = 246) participated in the study. They completed questionnaires assessing their experience of emotional or physical abuse, and provided information about family risk-factors and psychosocial symptoms, including PTSD-related symptoms. RESULTS: Incidence rates of maltreatment differed by country, as did levels of reported psychosocial symptoms. Incidence of emotional and physical abuse differed by region, with higher levels of abuse reported in the rural regions. In all four countries, a similar association between emotional/physical abuse and psychosocial symptoms was found, with the uniformly largest correlation between emotional abuse and anger. When examining the combined scores of emotional and physcial abuse, even higher correlation's were found, particularly in relation to anger and depression. In all four countries, parental overuse of alcohol was associated with emotional and/or physical abuse. CONCLUSIONS: Findings show differences by country in child-reported levels of emotional and physical abuse, but similar patterns of correlation with psychosocial symptoms and the risk factors of parental alcohol overuse and living in a rural area.  相似文献

The Effectiveness of Collaborative Augmented Reality in Gross Anatomy Teaching: A Quantitative and Qualitative Pilot Study     

Felix Bork  Alexander Lehner  Ulrich Eck  Nassir Navab  Jens Waschke  Daniela Kugelmann 《Anatomical sciences education》2021,14(5):590-604

In the context of gross anatomy education, novel augmented reality (AR) systems have the potential to serve as complementary pedagogical tools and facilitate interactive, student-centered learning. However, there is a lack of AR systems that enable multiple students to engage in collaborative, team-based learning environments. This article presents the results of a pilot study in which first-year medical students (n = 16) had the opportunity to work with such a collaborative AR system during a full-day gross anatomy seminar. Student performance in an anatomy knowledge test, conducted after an extensive group learning session, increased significantly compared to a pre-test in both the experimental group working with the collaborative AR system (P < 0.01) and in the control group working with traditional anatomy atlases and three-dimensional (3D) models (P < 0.01). However, no significant differences were found between the test results of both groups. While the experienced mental effort during the collaborative learning session was considered rather high (5.13 ± 2.45 on a seven-point Likert scale), both qualitative and quantitative feedback during a survey as well as the results of a System Usability Scale (SUS) questionnaire (80.00 ± 13.90) outlined the potential of the collaborative AR system for increasing students' 3D understanding of topographic anatomy and its advantages over comparable AR systems for single-user experiences. Overall, these outcomes show that collaborative AR systems such as the one evaluated within this work stimulate interactive, student-centered learning in teams and have the potential to become an integral part of a modern, multi-modal anatomy curriculum.  相似文献

Serving Others and Gaining Experience: A Study of University Students Participation in Service Learning     

Daniela Acquadro Maran  Giorgio Soro  Alessandra Biancetti  Tania Zanotta 《Higher Education Quarterly》2009,63(1):46-63

Unlike other countries, Italy has no 'service learning', the method enabling students to join accredited voluntary organisations in order to gain experience in serving others. An investigation was conducted in 2006 and 2007 to understand the opportunity that service learning provides to young adults, community and volunteer associations. The objectives were, first, to determine whether there is a need to forge links between the university and the world of volunteer work and, second, to describe the specific areas of action in the local context. A total of 603 video-recorded interviews were conducted. The findings show that there is a need to create a network for helping institutions, neighbourhoods and young adults to assess the demand and provide an organised response for educational and community needs. As a result, starting from this year, Turin University will be operating the first service learning in Italy.  相似文献
