It also explores whether it would be possible to solve the above pedagogical dilemmas through implementing collaborative learning mode in ESL. After analyzing the data collected from case study, classroom observation and post-hoc interviews, researcher discovers that collaborative learning mode exerts a considerable positive influence on reducing students' learning anxiety and rebuilding their self-confidence. In addition, peer interaction and group collaboration are highly motivating and effective for ESL learners at college level.展开更多

Readily accessible equipment, aswell as structured training curriculum should be provided to guarantee adequate practice hours and skillproficiency. Dry-lab training is typically adopted before animal model surgery, usually comprising ofpurpose-built bulky simulators that is neither accessible nor portable. In this technical note, we designed ahome-made simulator, using two 4 L water jugs as operating space that are communicated inside, plus anobservation hole taped in between to mimic the triangular working space of laparoscopic surgery. Imagingwas achieved via smartphone camera, which was wirelessly connected to a laptop and a projector for realtime display on multiple screens, using built-in multi-screen collaboration software. A self-regulated andproficiency-based training curriculum was adopted. This dry-lab simulator is low-cost, highly portable andeasily replicable for basic laparoscopic skills training for the beginners to intermediate surgeons, whichmay serve as a good way for the standardized residency and specialist training program.展开更多

Research, however,shows that many virtual CoPs do not achieve their expected potential because online interaction among healthcare professionals is generally low. Focusing on health visitors, who are UK qualified midwives or nurses who have undertaken additional qualifications as specialist public health workers in the community, the paper examines the factors that influence online interaction among health visitors collaborating to share knowledge and experience in a virtual CoP. The paper makes suggestions for how to improve online interaction among health professionals in virtual CoPs by increasing the size of membership in order to take advantage of both posting and viewing contributions, facilitating moderation to improve networking among geographically dispersed members groups and im-proving the topic relevance in order to stimulate contributions.展开更多

With the development of the Internet and the popularization of computers, cooperative education is becoming increasingly important. In consideration of the immature stage of the current domestic collaborative education platform, in order to promote the communication among students, teachers and parents, and to facilitate the collaborative supervision and management of teachers and parents, we design and construct the family-school collaborative education platform.展开更多

Efficient techniques for watching, navigating and sharing videos on mobile devices collaboratively are appealing in mobile environment. In this paper, we propose a novel approach supporting efficiently collaborative operations on videos with sketch gestures. Furthermore, effective collaborative annotation and navigation operations are given to interact with videos on mobile devices for facilitating users' communication based on mobile devices' characteristics. Gesture operation and collaborative interaction architecture are given and improved during the interactive process. Finally, a user study is conducted showing that the effectivity and collaborative accessibility of video exploration is improved.展开更多

Hence, these patterns support the comprehensiveness of both the interaction design and implementation while easing code modification for groupware application. Groupware is used to describe a broad range of technologies that support person-to-person collaboration. How to design and develop a groupware in an effective manner remains a research question worth exploring. This paper introduces a reusable method, patterns, to develop a single shared display application. Nine different interactive patterns that allow participants to interact collaboratively or non-collaboratively in a single shared display application are introduced in this paper. This is followed by the presentation of our quantitative results on the usability of the interactive patterns and the reusability of the patterns in designing and maintaining a single shared display application. From the results, not only are the patterns useful and easy to understand, the patterns actually ease the process of designing and maintenance during the application development under a single shared display.展开更多
