We aim to identify the engagement strategies that higher education students, engaging in emergency online learning in low-resource settings, perceive to be effective. We conducted a sequential mixed-methods study based on Moore’s interaction framework for distance education. We administered a questionnaire to 313 students engaging in emergency online learning in low-resource settings to examine their perceptions of different engagement strategies. Our results showed that student–content engagement strategies, e.g., screen sharing, summaries, and class recordings, are perceived as the most effective, closely followed by student–teacher strategies, e.g., Q and A sessions and reminders. Student–student strategies, e.g., group chat and collaborative work, are perceived as the least effective. The perceived effectiveness of engagement strategies varies based on the students’ gender and technology access. To support instructors, instructional designers, and researchers, we propose a 10-level guide for engaging students during emergency online classes in low-resource settings.

Screen Sharing

Real-time screen-sharing provides users with ubiquitous access to remote applications, such as computer games, movie players, and desktop applications (apps), anywhere and anytime. In this article, we study the performance of different screen-sharing technologies, which can be classified into native and clientless ones. The native ones dictate that users install special-purpose software, while the clientless ones directly run in web browsers. In particular, we conduct extensive experiments in three steps. First, we identify a suite of the most representative native and clientless screen-sharing technologies. Second, we propose a systematic measurement methodology for comparing screen-sharing technologies under diverse and dynamic network conditions using different performance metrics. Last, we conduct extensive experiments and perform in-depth analysis to quantify the performance gap between clientless and native screen-sharing technologies. We found that our WebRTC-based implementation achieves the best overall performance. More precisely, it consumes a maximum of 3 Mbps bandwidth while reaching a high decoding ratio and delivering good video quality. Moreover, it leads to a steadily high decoding ratio and video quality under dynamic network conditions. By presenting the very first rigorous comparisons of the native and clientless screen-sharing technologies, this article will stimulate more exciting studies on the emerging clientless screen-sharing technologies.

Screen Sharing

Abstract Objective Electronic health records (EHRs) in physician offices can both enhance and detract from the patient experience. Best practices have emerged focusing on screen sharing. We sought to determine if adding a second monitor, mirroring the EHR for patients, would be welcome and useful for patients and clinicians. Materials and Methods This mixed-method study was conducted in a general medicine clinic from March to June 2016. Clinicians and patients met in a specially equipped exam room with a patient-facing monitor. Visits were video-recorded to assess time spent viewing the EHR and followed by interviews, which were transcribed and analyzed using established qualitative methods. Results Eight clinicians and 24 patients participated. Main themes included the second screen serving as a catalyst for patient engagement, augmenting the clinic visit in a meaningful way, improving transparency of the care process and documentation, and providing a substantially different experience for patients than a shared single screen. Concerns and suggestions for improvement were also reported. Quantitative results showed high patient engagement times with the EHR (25% of the visit length) compared to reports in previous studies. The median satisfaction score was 5 out of 5 for patients and 3.3 out of 5 for clinicians. Discussion and Conclusion Providing patient access to the EHRs with this design was linked with several benefits including improved patient engagement, education, transparency, comprehension, and trust. Future studies should explore how best to display information in such screens for patients and identify impact on care, safety, and quality.

Share Information

Web conferencing is a technology that allows groups of individuals in a variety of diverse locations to communicate and share information without having to leave their desks. It provides features such as whiteboarding, screen sharing, chat, and polling. It eliminates the need to travel, reduces downtime, increases efficiency, and reduces costs. AT&T worked on proofs of concepts and prototypes for personal conferencing systems for 20 years and finally released its product in 1993 (Perey, 2003). Microsoft released NetMeeting in about 1995. Wooley now lists 95 real-time collaboration products and Web sites on his Web site, ThinkofIt. com. The growth of real-time collaboration has grown significantly and been more successful in the last few years, as the CPUs in PCs are faster, the PCs have more memory, and more bandwidth is available and cheaper. Frost and Sullivan’s 2002 report estimates that by 2008, $2 billion will be spent on Web conferencing (as cited by Perey, 2003). This technology allows a business to conduct training simultaneously, globally creating a collaborative learning environment while keeping costs down.
