The effect of online co-regulated learning in the implementation of team-based learning on improving students’ involvement     

Chia-Wen Tsai 《高等教育研究与发展》2015,34(6):1270-1280

Many education institutions and teachers are recognizing and applying online learning and related educational technologies to help students achieve satisfactory learning performance. Due to the free entertainment on the Internet that may distract students’ attention from online courses and with the purpose of developing students’ teamwork abilities, the author in this study adopted team-based learning (TBL) and co-regulated learning (CRL) to develop students’ involvement in a blended computing course. The subjects in this study were 111 first-year students from three classes taking a compulsory course titled ‘Applied information technology: data processing’. The first group (G1, which received online TBL and CRL) and the second group (G2, which received online TBL only) were the experimental groups. The last group (CG), which received the traditional teaching method in a blended learning environment, served as the control group. The results in this study indicate that students who receive the online TBL have significantly higher involvement than those without. However, the online CRL does not contribute to better development of students’ involvement in the implementation of TBL. The insights for teachers who plan to adopt e-learning, and the reasons for the ineffectiveness of CRL, are discussed in this study.  相似文献

Small Circles: Mobile Telephony and the Cultivation of the Private Sphere     

Rich Ling  Johannes Bjelland  Pål Roe Sundsøy  Scott W. Campbell 《The Information Society》2014,30(4):282-291

This article examines how we use mobile telephony to maintain our physically and socially closest social circle. The analysis is based on traffic data gathered from Norway using approximately 24 million calls and texts made by private individuals. Previous research has shown that our temporal and spatial movement is highly predictable and that the majority of calls and text messages are sent to only four to six different persons. This article extends this research by examining both tie strength and the distance between the interlocutors in urban and rural settings. The findings show that even as information and communication technologies (ICTs) potentially put the world at our fingertips, the mobile phone is an instrument of a more limited geographical and social sphere. Approximately two-thirds of our calls/texts go to strong ties that are within a 25-km radius.  相似文献   

Real time exploration and management of large medical volumetric datasets on small mobile devices—Evaluation of remote volume rendering approach     

Tomasz Hachaj 《International Journal of Information Management》2014

In this paper I present the architecture of system that can be used for real time exploration and management of large medical volumetric datasets. The new state of the art solution presented in this paper is an example of visual data management system. System prototype evaluation proved that it is possible to use low-powered (and cheap) up-to-date mobile devices with programmable GPUs as the remote interfaces for exploration of large volumetric medical data. The implementation was done with high-level programming language that enables portability between different hardware models. The lack of lossy compression enables to display high quality medical images visualizations without any simplifications and noises in frequency domain. The prototype of system is capable to remotely render and send to a client (for example cell phone or tablet) rendered data with frequency 30 fps with limited resolution during interaction. One second after the interaction is finished client machine receives full resolution image. The evaluation of the system was performed on volumetric computed tomography angiography image with approximate size 512³ voxels.  相似文献
