Cloud technology is a new computing model. It distributes computation tasks in theresource pool, which consists of a large number of computers, so the applications can obtaincomputation power, storage space, and software services on-demand. This resource pool isknown as the “cloud” (Zhang, Yan, & Chen, 2012). For decades, rapid developments ininformation and communication technologies meant that education has been required tocontinually adapt to these changes. Cloud technology can be thought of as a device tosupport learning and teaching models for the 21st century and challenge-based learning(Yoosomboon & Wannapiroon, 2015). According to Jalali, Bouyer, Arasteh, and Moloudi(2013), cloud technology, a new paradigm of distributed computing, presents many newideas, concepts, principals, technologies and education styles into service-orientedcomputing. Cloud technology is the core value of the development of CLE; mostpersonalized learning systems are designed for e-learning on personal computers or mobilelearning devices (Nedungadi & Raman, 2012). Nedungadi and Raman (2012) developed acloud-based adaptive learning system by utilizing mobile devices in classrooms. Theirparticipants were 61 K–10 students and the experiment combined formative evaluation withan online learning environment. Results of their study indicated that students couldseamlessly adapt or use e-learning and m-learning systems without affecting their learningperformance. Teachers could monitor the performance of individuals and groups, andstudents were very interested in using mobile devices and gained a sense of participation.Lockyer and Patterson (2008), following the development and diffusion of Web 2.0technology, used Flickr to examine the effects of social network technology on formallearning. The network-based learning course in their study assisted students with the useof information technology for learning on the Internet, validating learning theories, andlearning techniques of practical knowledge. Their research results indicated that learnersperceived different levels of participation in different themes, and that online coursesallowed learners to engage in more in-depth participation and to better understand learningactivities with no constraints of time and place. In the application of Wikispaces, the Facultyof Medical and Health Sciences of New Zealand’s University of Auckland carried out 16Educational Technology Professional Development (ETPD) workshops for a two-year study;research results showed that a project-based workshop allowed learners to gain morespecialized knowledge and problem-solving abilities, and increased willingness in using it 136 Tzu-Hua Huang, Yuan-Chen Liu, & Pei-Chun Yu(Doherty, 2011). The data storage function of cloud technology can extract participants’feedback for analysis; the adaptive and expandable framework increased learners’ interestand sense of participation; and the function of powerful link enabled more in-depthparticipation and better understanding of learning activities. These functions imply that theinteraction, joint editing, and data storage of a CLE can be applied in extensive and in-deptheducational uses. The latest study on a cloud-based reflective learning environment provedthe effectiveness and usefulness of reflection ability to students during and after class. It alsofacilitated teachers in monitoring and planning under such an environment (Lin, Wen, Jou,& Wu, 2014). In conclusion, the technology of CLE creates more opportunities to engagestudents in learning tasks, and makes learning remote and flexible.
