Semi‐automating the manual literature search for systematic reviews increases efficiency     

Andrea L. Chapman  Laura C. Morgan  Gerald Gartlehner 《Health information and libraries journal》2010,27(1):22-27

Background: To minimise retrieval bias, manual literature searches are a key part of the search process of any systematic review. Considering the need to have accurate information, valid results of the manual literature search are essential to ensure scientific standards; likewise efficient approaches that minimise the amount of personnel time required to conduct a manual literature search are of great interest. Objective: The objective of this project was to determine the validity and efficiency of a new manual search method that utilises the scopus ? database. Methods: We used the traditional manual search approach as the gold standard to determine the validity and efficiency of the proposed scopus method. Outcome measures included completeness of article detection and personnel time involved. Using both methods independently, we compared the results based on accuracy of the results, validity and time spent conducting the search, efficiency. Results: Regarding accuracy, the scopus method identified the same studies as the traditional approach indicating its validity. In terms of efficiency, using scopus led to a time saving of 62.5% compared with the traditional approach (3 h versus 8 h). Conclusions: The scopus method can significantly improve the efficiency of manual searches and thus of systematic reviews.  相似文献   

Malaysian primary pre-service teachers’ perceptions of students’ disruptive behaviour     

Norzila Zakaria  Andrea Reupert  Umesh Sharma 《Asia Pacific Education Review》2013,14(3):371-380

The purpose of this paper was to investigate Malaysian primary pre-service teachers’ perceptions of students’ disruptive behaviour and their self-reported strategies to prevent and to manage such behaviours. Results indicate that Malaysian pre-service teachers understand disruptive behaviours to be those that disrupt the learning and teaching process. They identified the cause of student disruptive behaviour as factors residing within the individual student. Pre-service teachers here reported preventative strategies in terms of changing teaching strategies and threats to use punishment. When addressing students’ disruptive behaviour, pre-service teachers reported that they would use one-to-one counselling with students and remove tokens or hold back rewards. A discussion regarding the implications for teacher education institutions and future research concludes this paper.  相似文献   

Issues in Component Computing: A Synthetic Review     

Andrea A. diSessa  Flavio S. Azevedo  Orit Parnafes 《Interactive Learning Environments》2013,21(1-2):109-159

This paper provides a review of the rhetoric behind the component movement in educational software, and a critical analysis and synthesis of issues underlying the movement. We draw on case studies of several significant recent component projects in order to assess claims and to uncover and examine issues that are less often considered. While our empirical base cannot definitively answer all the questions raised, we hope to bring some clarity and some empirically based judgments to bear on how a promising technological innovation can best serve educational ends. Our study led to a focus on three critical issues: (1) the nature of the environment in which components are configured and used; (2) the extent of modifiability that is necessary for effective re-use of components; (3) how the work of designing components and component configurations is distributed among people with different competencies.  相似文献   

Students' Perception of School Violence and Math Achievement in Middle Schools of Southern Italy     

Andrea Caputo 《Educational Assessment》2013,18(4):269-284

This study aims at both investigating bullying episodes occurring at school across different grades (from 6 to 8) and evaluating whether educational achievement in math can be predicted on the ground of students' perception of school violence. The sample was composed of 11,064 students coming from middle schools of Southern Italy. Standardized tests were submitted to measure students' performance in mathematics. Background questionnaires were used to assess students' perception of school violence in relation to some bullying episodes occurring in the last month. Students' perception of school violence, which tends to decrease from Grade 6 to 8, can be considered a valid predictor of their math performance, also controlling for both individual and family background, school context, and geographical characteristics.  相似文献   

Building Relationships through a Digital Branch Library: Finding the Community in Community College Library Websites     

Andrea M. Pampaloni  Nora J. Bird 《Community College Journal of Research & Practice》2013,37(12):1125-1141

This study evaluates whether or not community college libraries have in place the characteristics necessary to develop digital branch libraries to meet the expanding and changing needs of their publics. Using Hon and Grunig’s (1999) relationship building criteria as a framework, 98 community college library websites were analyzed to determine if they can be considered digital branch libraries (King, 2009). Digital branches go beyond offering mere functionality to embody relational aspects that are critical to the success of service-based organizations. That is, they provide at least the same level of services as their brick and mortar counterparts through real staff, real collection, real building, and real community. Findings indicate that while aspects of all of King’s criteria were present, representation was inconsistent and often weak; further, the emphasis was on functional features, suggesting a need for greater relationship building practices in order to engage with their publics. Collective results are discussed, and recommendations for improvement and areas of future research are offered.  相似文献

Integration of knowledge management and collaborative learning by technical supported communication processes     

Andrea Kienle 《Education and Information Technologies》2006,11(2):161-185

To date the development of technical systems to support learning either in schools and universities (CSCL-systems), or in companies (knowledge-management systems) have largely developed separately concurrent, with no or little mutual exchange of experience. The approach presented here seeks to combine the strengths of both lines of development in order that both benefits from each others advantages achieve advantages for each development. Detailed requirements engineering is presented regarding, three research fields: communication theory; learning processes; and a study in companies. The requirements collected led to a sophisticated concept of annotations where annotations serve as communicative contributions, and (segmented) material is used as context. The combination and distinction between communicative contributions, and the material itself is a suitable approach for integrating the advantages of CSCL-systems (communication support) and knowledge management systems (support of content storage). These requirements are combined in a software system, KOLUMBUS, presented with its key features. To gather experience with KOLUMBUS and to convey potential for further improvement, two case studies were conducted. The main results, advantages and further potentials derived from these two case studies are described in this paper. The paper concludes with design recommendations for similar technical systems, as well as organizational hints for CSCL-groups (in schools or universities as well as in companies).  相似文献   

Sonic Oppression,Echoes of Resistance and the Changing Soundscapes of Rio’s Favelas in the Build-Up to the Olympics     

Andrea Medrado  Renata Souza 《Journal of Radio & Audio Media》2017,24(2):289-301

This article aims to explore the ways in which the transformations that Rio de Janeiro experienced prior to hosting the Olympics echo in the soundscapes of Favela da Maré. Here, we draw from an (auto)ethnographic approach, and combine theoretical perspectives from sound studies, auditory culture, and studies of activist media. Our research indicates that some of the authorities’ oppressive impositions on favela residents’ daily lives manifest precisely through the suppression of sounds. We would like to argue that activist media in Latin America can be better understood if situated in a complex set of daily rhythms.  相似文献
